The only differences between micro and macro evolution are time and scale. That there are still unanswered questions is without doubt. However, it is obvious that the vast majority of the scientific world accepts evolution as a truth. The micro and macro qualifiers are just silly and too frequently used only for combat.
If anyone is interested in the actual theory (and not a cartoon straw-man), its predictions, and the confirmation of those predictions of macro-evolution:
http://www.talkorigins.org/faqs/comdesc/
Thanks, I'll try to wade through it...
Nyarlathotep, you have come up with some excellent resources!
For a quick sample of how much 'crack-pottery' is in this thread, let's just consider the following similar statements:
------------------------------------
"However how do you think that macro evolution makes any sens when it does not even deliver an explanation of why it happened?"
------------------------------------
"Macro is when a honeycreeper becomes a crow. (no explanation given of why this happened)
(the idea is that with even more generations the honeycreeper could become an entirely new specie with different body structure)...A theory/hypothesis is an explanation of the facts, it deals with the why it happened...Darwin delivers the why with his "natural selection" paper for micro-evolution which was magnificent...But when he proposed the macro-evolution, he did not deliver the explanation, he just postulated the idea with the current evidence he had at the time."
-------------------------------------
"If one wishes to claim that the structure of bones changes, then he must provide an explanation of why it happened, that is what science demands, not me."
--------------------------------------
"MACRO EVOLUTION HYPOTHESIS scraps that requirement(the WHY) and thus it becomes unscientific and contradictory to MICRO EVOLUTION THEORY itself."
--------------------------------------
--------------------------------------
According to the (in)famous crackpot index:
http://math.ucr.edu/home/baez/crackpot.html
"10 [crackpot]points for arguing that while a current well-established theory predicts phenomena correctly, it doesn't explain "why" they occur, or fails to provide a "mechanism".
That is 40 crackpot points right there!
The joke is on the creationist! If you accept any serious degree of microevolution then you have accepted all of the starting conditions in order for Darwinian natural selection to act. Moreover, there is no inherent stopping point in the light of modern genetics. (Before modern genetics demonstrated otherwise, it was thought by some that small changes would be swamped out before they got very far.)
In some cases life forms have been connected by "microevolutionary" steps at the genus level, let alone between species! As for smooth, living gradients between good species, check out "ring species." Ring species are species whose ancestors have spread out over a vast ring of territory (such as some trees bordering the North Pole or a certain lizard whose close relatives form a ring around the central valley in California). Each step around the ring represents only a change in subspecies, but the two endpoints are distinct enough to qualify as two certified species!
Evolution was originally viewed as a slow, step by small step process that went on at a continuous rate. For some "lower" life forms that is actually the case. However, various problems led Stephen Jay Gould and Niles Eldredge to argue that most of the really big changes (macroevolution) proceeded in a wholly different manner. A species (one reasonably well adapted) mainly sat around doing nothing (it would have to evolve away from its ideal environment if it evolved further), then because of a dramatic change in the environment (weather, predators, a big meteorite, etc.) everything suddenly went into an evolutionary overdrive. In most cases it was probably a small subgroup that had colonized a new environment; evolution can move rapidly in small groups moving into new environments. Thus, evolution stands still for many species but, on occasions, takes big leaps. (These "big leaps" don't skip any steps. It's just that evolution is moving at a much faster rate. If you are pushed into a new environment, it's adapt quickly or die.) Steven Jay Gould and Niles Eldredge's idea--not a refutation of evolution but a modification--is accepted by many biologists today though some debate continues. Punctuated Equilibrium, the idea advanced by Stephen Jay Gould and Niles Eldredge, gives a natural explanation for statistical gaps often (but not always) documented at the species or genus level. (At the highest taxonomic levels fossils between major types blend into each other so smoothly that, in some cases, paleontologists are stumped as to which side of the line to place a fossil! Doesn't sound like the creation of unique kinds (with later small variations) to me!
More recently it has been discovered that some surprisingly big changes can happen "overnight" if certain control genes are hit by a mutation. The details at the DNA level proceed step by step, aside from segments being swapped or inserted, or a misalignment, but even a small change in DNA can be translated into a major change in the structure of an animal. There is strong evidence that some of the biggest changes in the evolution of "higher" life may have involved some fairly large but survivable steps!
By the way, if a creationist wants to personally witness 20 million years or more of evolution (macroevolution) then he had better plan on living a long, long time! However, if that creationist wants to see compelling evidence for 20 million years or more of evolution, he need go no further than Hawaii--or a hundred other places.
Yea most of what you said is correct.
Punctuated Equilibrium was the reply to the question?
If there should be a gradual change like Darwin proposed, why doesn't it appear in the fossil record?
Why does the fossil record show new species that seem to just appear?
(eg Cambrian Explosion)
Stephen Jay Gould tried to explain this with stasis and "overnight" mutations that do the same gradual stages but at a faster rate to the point of leaving no fossils behind.
Again a nice idea but there is no evidence for it to apply to anything else but the fish example he used as an explanation.
Fish are easy to isolate but how can you apply the same principle with apes which are migratory creatures?
It is true that mutations occur at a faster rate with interbreeding and sudden change of environment but Stephen Jay Gould failed at showing positive mutations to occur.
The fish did not become a lizard or something, they became a new type of fish which is somewhat inferior compared to the other fish at sea/river but more adapted to that small pond they were in.
Stephen Jay Gould failed also to show how those new fish actually outlived the rest of the fish which was the basis of Natural Selection. Survival of the fittest.
Thus Punctuated Equilibrium is more of an exception to the rule then a help to a Theory, and that is why it was so criticized by evolutionists themselves since they wanted a general theory that explains all the species origin.
The Punctuated Equilibrium explanation given doesn't show that, it actually reveals some of the problems that Macro-evolution already has that the evolutionists do not want to address:
-- Stasis of most species(most don't seem to change after millions of years in the fossil record)
-- New species just appear in the fossil record without links in between that show a gradual change.
"More recently it has been discovered that some surprisingly big changes can happen "overnight" if certain control genes are hit by a mutation."
"There is strong evidence"
It is possible but I would still like the reference of that, because I want to see how it is related to Macro-evolution rather Micro-evolution.
" paleontologists are stumped as to which side of the line to place a fossil"
You mean they are stumped at what to label them?
Fossils are not easy to distinguish since it depends on the state of the fossil, age and also on the possibility that the specimen is a fossil because it could not survive in nature. If more then one of the same type is found, then yes the specie was indeed popular to leave 2 fossils since they are very hard to make/find/salvage.
Jeff Vella Leone,
Thank you for taking the time to reply. I believe (after reading many of your posts) that you don't really understand the fossil evidence for evolution, evidence that is absolutely decisive. Therefore, let me recommend an excellent book: "Evolution: What The Fossils Say and Why It Matters" by Dr. Donald Prothero. I hope that you can read this book since it is one of the best books on the subject, a book for an intelligent reader but not necessarily simple reading. Dr. Donald Prothero, with whom I made two trips, is a humble geologist of international fame who is associated with Caltech. He knows what the fossil record is all about! Also, you should try to follow up on the resources offered by Nyarlathotep as they are excellent. As one who is searching for the truth, you owe it to yourself to study those resources even though some of it is not easy.
As does "The Pragmatic," I have trouble understanding your use of microevolution and macroevolution. Your use of those words are NOT how scientists use them. I consulted "The American Heritage Dictionary of Science" which mostly confirms my own use of those terms. Microevolution mostly refers to sub-species evolution, evolution within a species that does not go outside its borders. Macroevolution refers to evolution leading to new species, especially to higher taxonomic categories such as families or phylae. The evolution of a horse or elephant from dog-sized, Eocene animals would be macroevolution. The evolution of birds from dinosaurs would be macroevolution. They are labels, not explanations. Therefore, there is no such thing as "microevolutionary theory" and "macroevolutionary theory." Those words describe how much evolution has occurred, not how it has occurred. They are not important scientific terms, only terms of convenience.
Now, I will do my best to reply to your post:
[Punctuated Equilibrium was the reply to the question?]
It is the name Stephen Jay Gould and Niles Eldredge gave to their modification of the prevailing theory of evolution.
[If there should be a gradual change like Darwin proposed, why doesn't it appear in the fossil record?]
It most certainly does appear in some cases! Keep in mind that evolution proceeds most rapidly in small, outlying groups living under different environments. Fossil preservation is few and far between, limited mainly to unusual events, and those fossils of small groups of animals or plants living in limited areas usually don't get preserved at all. If a small group of plants or animals evolves for a long time, through many stages, and then becomes very successful and large, the fossil record will usually show fossils from the originally successful population followed by the later successful population. The in-between fossils, belonging to small populations in small areas, will usually not be found. That is one way to get a "gap" in the fossil record. Conditions are rarely so good and consistent as to preserved a long series of gradual changes in the fossil record, especially for larger animals. If you calculated the depth of earth needed to bury one horse fossil every 10,000 years, then another layer on top of that, etc., you would begin to understand how much sediment would be needed to cover the fossil horse record! Preserving gradual changes over 50 million years is out of the question for a variety of reasons, including erosion. However, you don't need every single step to see the trend.
[Why does the fossil record show new species that seem to just appear? (eg Cambrian Explosion)
Stephen Jay Gould tried to explain this with stasis and "overnight" mutations that do the same gradual stages but at a faster rate to the point of leaving no fossils behind. Again a nice idea but there is no evidence for it to apply to anything else but the fish example he used as an explanation.]
What you see statistically in the fossil record are the very successful species whose fossils have a chance to be preserved. You don't usually see the intermediate fossils left by small, rapidly evolving populations. Another possibility (as was true for some trilobites in New York) is that a species may do its evolving elsewhere before returning to the original home grounds, that being the location checked by the geologist. Therefore, new species often (but not always) seem to appear out of nowhere in the fossil record.
By the way, the Cambrian "explosion" probably took 10 to 30 million years. It didn't happen overnight! Just prior to that time the Earth seems to have been frozen over, and one idea is that it thawed to a degree that allowed life to take off. Another idea is that oxygen reached a critical level and allowed more complicated life to develop. We don't have the final answer, but there is no problem here for evolution. Since your knowledge of the fossil record is very weak, you should be careful about saying "there is no evidence." My guess is that there is plenty of evidence, which would explain why punctuated equilibrium is widely accepted by biologists and paleontologists. Note that Stephen Jay Gould was not talking about "overnight mutations." He was talking about a period of rapid evolution driven by environmental pressure.
[Fish are easy to isolate but how can you apply the same principle with apes which are migratory creatures?
It is true that mutations occur at a faster rate with interbreeding and sudden change of environment but Stephen Jay Gould failed at showing positive mutations to occur.]
Mutation rates have nothing (little) to do with the environment or interbreeding! It is natural selection working on existing genetic variability, driven by environmental pressure, that sets the rate (among other things). Interbreeding merely concentrates mutations already existing. Of course positive mutations occur! How else did desert plants become adapted in wonderful ways to desert environments?
[The fish did not become a lizard or something, they became a new type of fish which is somewhat inferior compared to the other fish at sea/river but more adapted to that small pond they were in.]
I don't know what type of fish Stephen Jay Gould was studying, but I do know that fish fossils grade smoothly into amphibian fossils which grade smoothly into reptile fossils.
[Stephen Jay Gould failed also to show how those new fish actually outlived the rest of the fish which was the basis of Natural Selection. Survival of the fittest.]
There is no such requirement! You need to hit the books and gain a basic understanding of evolution. Most evolution is a branching out process that does not require the extinction of the original population. (An excellent, beginning book to read is: "Undeniable" by Bill Nye (known as the science guy in the U.S.).)
[Thus Punctuated Equilibrium is more of an exception to the rule then a help to a Theory, and that is why it was so criticized by evolutionists themselves since they wanted a general theory that explains all the species origin.]
Today, Punctuated Equilibrium is widely accepted among biologists and paleontologist because it explains so many facts. To better appreciate it you need to study a good site on the Internet.
[The Punctuated Equilibrium explanation given doesn't show that, it actually reveals some of the problems that Macro-evolution already has that the evolutionists do not want to address:
-- Stasis of most species (most don't seem to change after millions of years in the fossil record)
-- New species just appear in the fossil record without links in between that show a gradual change.]
Punctuated Equilibrium explains a lot of facts, especially why new species "just appear" in the fossil record without links showing a gradual change. Some of this I explained above. Why wouldn't evolutionists want to address scientific problems in their theories? Isn't that what Darwin did, something that all good scientists do?
["More recently it has been discovered that some surprisingly big changes can happen "overnight" if certain control genes are hit by a mutation."
"There is strong evidence"
It is possible but I would still like the reference of that, because I want to see how it is related to Macro-evolution rather Micro-evolution.]
It is demonstrated in the laboratory. For instance, a simple mutation can convert a flies halteres into wings if I remember correctly. The shape of the adult human face is that of an immature chimp's. There is a whole area of study regarding the apparent preservation of immature features on one species in a related species. You should be able to find something on the Internet. If you can't, I can try to help you. Such major changes would be a basis (an important building block) for very large evolutionary changes.
[" paleontologists are stumped as to which side of the line to place a fossil"
You mean they are stumped at what to label them?]
Yes.
[Fossils are not easy to distinguish since it depends on the state of the fossil, age and also on the possibility that the specimen is a fossil because it could not survive in nature. If more then one of the same type is found, then yes the specie was indeed popular to leave 2 fossils since they are very hard to make/find/salvage.]
Some fossils may be hard to distinguish from others because of the reasons you cited. Usually it is not a problem since multiple fossils are usually available and, in some places, even whole.
Thank you for your lovely posts, Greensnake. You are a wonderful teacher!
My pleasure, CyberLN. For me, science is a fun exploration of reality. It's sticking your nose through the cosmic sphere (as in that old woodcut) to see what lies beyond. It's the greatest adventure game of all!
Jeff Vella Leone (5-11 7:54),
I thought I'd try to answer some of your previous questions.
[IF man evolved from another completely different specie through a very very long period of time (macro evolution), this should show up in the fossil record.
What would show up?
Intermediary species in between that would show a very linear progression from ape (proposed by Darwin) and a human fossil.
Basically a version of an ape which has human like features.]
Early ape and hominid fossils are rare! (Hominids are members of the family Hominidae, those primates that make up the human branch of the "evolutionary tree." All are extinct now except for one member of that family--us.) The remains of dead apes and hominids, whether in jungles or on savannas, are poor candidates for fossil preservation. They just sit there until picked apart by animals or degraded by nature. The necessary quick burial in sediment is hard to come by. No paleontologist would ever expect to find an extended sequence of nice intermediates that show a very linear progression! They celebrate wildly when a few bones are found!
Nevertheless, over the years a considerable number of hominid fossils have been found. You can read about them in Dr. Prothero's book: "Evolution: What The Fossils Say and Why It Matters." The older hominid fossils show a distinct mix of human and ape characteristics. The oldest ones are generally ape-like and have small brain sizes. Neanderthals, our closest relatives, are very human-like but much more robust. Did you know that some human populations have a significant number of Neanderthal genes?
[Well, Darwin failed at showing those "links" himself so HE estimated that the Missing links should be found in around 10 years given the rate at which fossils were being uncovered at the time, ELSE HE SAID THAT IF THEY ARE NOT FOUND BY THEN, HIS HYPOTHESIS WOULD BE WRONG.]
In Darwin's time the hominid fossil finds were practically non-existent. Quoting him this way is wrong, because the measure of a scientific hypothesis is always the evidence--never an authoritative statement. Furthermore, I doubt that Darwin ever said such a thing in quite that way. I think that Darwin has been quoted incorrectly. Let's go back to the source and find that statement in its actual context. I'd like to see what he really said.
[There is no definitive evidence that any of the fossils we have of apes show human like features.(human structure vs ape structure)
But if you think there is, then please tell me where to find it since I have been digging hard for it and all the papers I have read on the subject missed it somehow.]
Aside from Dr. Prothero's book (mentioned above) let me also recommend:
http://evolution.berkeley.edu and http://www.talkorigins.org
Talk Origins has a lot of good material, some of it dealing with evolution.
Jeff Vella Leone (5-11 10:06),
[Evolution occurs with adaptation to an environment, you must also provide the environment that pushed towards that change.
Until that environment is provided macro evolution for human origins remains an unsupported extraordinary claim.]
Enough fossils and other evidence will make the case--even without knowledge of the environment. (See Dr. Prothero's book for a discussion of the fossils that show human evolution.) Yet, we do know that around the time hominids arose the African environment was that of a savanna. Jungle had given way to a savanna. If the dates are correct, then early apes living in trees had to largely abandon them since those trees were now spread out over the savanna. Perhaps that had something to do with the evolution of upright humans.
[When it comes to scientific papers the evidence in them falls short to 0 my friend.
But I would be happy if you prove me wrong. This is a subject I have huge interest in.]
I must completely disagree! As I mentioned earlier, over the years quite a few hominid fossils have been found and they all get reported in various scientific journals. Please read Dr. Prothero's book and decide whether the evidence is still near zero.
["The recurrent laryngeal nerve in mammals is another example of evolution and so are the vestigial organs."
How are they proof of macro evolution?]
Dr. Prothero describes the case for the giraffe nicely. In the giraffe the laryngeal nerve is an incredibly clumsy "design" that actually can endanger the giraffe to some extent. How did it get that way? Evolution is the clear answer! The story as to how we know that is best left to Dr. Prothero, being a bit lengthy, but you can probably find the details on the Internet. (Look under "giraffe" and "laryngeal nerve.") Remember, Macroevolution refers to evolution above the species level.
Vestigial organs were once useful but are now obsolete--with respect to their original use. (Evolution can sometimes recycle a vestigial organ for another purpose.) If an animal has a vestigial organ that only makes sense in a wholly different animal, then that is prime evidence of macroevolution. Whales (some) still have vestigial remnants of hind legs which clearly served a completely different animal in the past. Indeed, whale fossils trace back to a four-legged river animal! Vestigial organs are windows into the past and speak powerfully of macroevolution.
[Yea that is what Darwin proposed in his paper:
"NATURAL SELECTION" (postulated micro-evolution )
Then he made another paper named:
"Origins Of Man"(postulated macro-evolution)]
As I mentioned in a later post, and I think it good to repeat it here, microevolution and macroevolution are not explanations. They are labels. Microevolution mostly refers to evolution that does not go beyond the species level and it results in sub-species, varieties, or just some small changes. Macroevolution refers to evolution that has exceeded the species level, especially evolution that has exceeded the higher taxonomic levels. They are words of convenience and not important scientific terms.
Darwin's first book identifies natural selection as the main engine of evolution. Today, we know that there are some other factors at work, but natural selection is still the main engine. Natural selection applies to human evolution as well, but Darwin (already fearing loud protests) saved the matter of human evolution for a much later book. Darwin is not offering two different theories in his two books. He offers one theory that applies to two subjects.
["missing links are being discovered everyday and you can go online and look at the fossil record which reflects them"
Nope that is a lie, you failed to even address my description of what missing links are, so should I even dignify you with a reply? or should I wait till you actually start addressing my points on the subject?]
But it is the truth! (Once again, please read Dr. Prothero's book to feel the massive weight of the fossil evidence.) May I add that your definition of a missing link is not the point. We are concerned with a paleontologist's understanding of a missing link. The paleontologist and evolutionary biologist are in a better position to say what we should expect to find in the fossil record.
Jeff Vella Leone (5-11 15:12),
["DNA has proven that were are all descendants from the same single cell."
Nope it did not, where is this proof?]
["DNA has proven that were are all descendants from the same single cell. "
I wonder how are you going to support that claim?
A cell does not necessarily have a nucleus, which contains the DNA.]
In a nutshell the proof goes like this: Over time DNA collects various changes for a variety of reasons. Now, if a species has recently split into two or more species then all of those species will have very similar DNA with only a few minor differences. But if the split took place a long time ago, if their common ancestor lived many tens of millions of years ago, then the differences between the DNA of those surviving species will be much greater. By carefully studying the similarities and differences between the DNA of all species, we find that it is possible to construct an "evolutionary tree" diagram! This is the primary prediction of macroevolution! There is no way to get such a diagram without obvious fudging unless life arose from primitive cells. That's where the root-end of the "evolutionary tree" points. (Life might have begun with a number of different cells in different locations, but one line survived and all life today bears its stamp.)
The second point is that the DNA code is a true code (not being tied to any direct, functional application) and there is no reason in the world for thinking that unrelated life forms would all use the same DNA code. The fact that they do use the same code (with a few very minor exceptions) is strong evidence that life all came from a common source and that would point to a primitive cell. Whether it actually comes down to one, particular cell I don't know, but such a cell would be the logical source of a very specific DNA code.
It's true that prokaryotes (bacteria, for example) don't have a nucleus, but they still have DNA which often forms a loop in the cytoplasm.
[You seem to jump to Abiogenesis here instead of evolution which is well acknowledged that it is not proven or supported with enough evidence yet.]
What hasn't been found (yet) is a clear pathway from non-living to living. The fossil record goes back to a time where no life can be found. A little further up the geologic column we might find chemical hints of life. Still further up are the prokaryotes which have no nucleus. Still further up, we find single celled fossils with nuclei. Much further up, near the Cambrian, we get true multi-celled animals (rather than colonies of cells). After that, the evolutionary road produces complex plants and animals. It seems to me that the most reasonable conclusion is that between the non-life and life parts of the geologic column life must have appeared. Abiogenesis now has some plausible explanations that are far better than the earlier speculations, but the details have yet to be worked out.
Jeff Vella Leone (5-11 18:14),
["DNA Structure by Watson and Crick supported the theory of Evolution"
how did it support macro evolution?
please explain to me, which parts supports macro evolution?]
DNA supports the "evolutionary tree" diagram as explained above. It may interest you to know that a virtually identical "evolutionary tree" is supported by a study of the similarities and differences between cytochrome-C molecules. Cytochrome-C plays such a basic role at the cellular level, doing exactly the same thing for grass as for humans, that you could probably switch the two and never know the difference! Cytochrome-C has enough non-critical areas so that random mutations can collect there without doing any harm. Therefore, if two species diverged recently then their cytochrome-C molecules have the same (nearly) mutation pattern. If the two species are "distant cousins" then their cytochrome-C mutation patterns will be much more different. Using the same idea as for DNA, we can study the similarities and differences between the cytochrome-C of different species, and the same "evolutionary tree" relationship (with only minor differences) pops out! If not evolution, then what? And, we can create the same evolutionary tree from the order and nature of the fossil record and also from anatomical studies of living animals. The odds that such diverse studies should all come up with the same "evolutionary tree" relationship by chance is about as close to zero as you can get! The only common factor among these methods is that changes over time have been, in some way, recorded. Here is the main proof of macroevolution. We haven't even touched the other major evidences such as geographical distribution, vestigial organs, homologies, and many others. One interesting side-line is that the principles of natural selection work wonderfully well in industry. That's a whole 'nother story!
[It was shocking to me that almost all papers just refer to Darwin original paper on the subject as a reference and just move on the specific area they are building a hypothesis on.]
Are you kidding me? Modern scientific papers would have no reason to cite Darwin unless it is an historical note. If you are a scientist you cite the most recent research relevant to your paper. Evolution has advance 150 odd years since Darwin! Darwin's genius is in identifying natural selection as the main engine for evolution, which is central to biological evolution (micro and macro) to this very day.
[I can imagine god creating Adam and Eve, which I know it is bullshit, and YET I cannot imagine this dam environment,
=that is the nail in the coffin for macro evolution for me and any other scientific person.]
Sorry, but you don't speak for me! Elsewhere--very briefly--I have given the main proof for macroevolution, i.e., evidence that has no reasonable alternative interpretation. Scientists have discussed the probable environments at the time of early hominid evolution, but it isn't even needed to make the case for macroevolution.
[--What natural environment could make a night vision creature that hunts at night like a Miocene ape become a color vision human that sucks at hunting at night?]
[What all the apes became selective and stopped eating grass/nuts? a collective decision?]
[--Apes had hair to protect them from cold and sun radiation, we simply don't, what environment could possibly do that?]
Apes do not seriously eat grass, which has too much silicon and requires special digestion (as found in bovines). But my real point is this. The fact that you cannot imagine how something happened is not an argument against it! Isn't that what we call the "argument from ignorance?" That someone can't think of how powered flight might be done, or how the Bombardier Beetle evolved its systems for shooting scalding fluid, does not mean that no one ever will. At one time not even the best scientists had the slightest clue as to what made the sun shine. Darwin, himself, was greatly troubled because a heat dissipation argument ruled out the time he needed for evolution, and try as he might Darwin could not imagine a way around it! However, in time airplanes were built, the Bombardier Beetle's evolution explained, the means for the sun to shine understood, and the discovery of radioactivity gave Darwin all the time he needed for his evolution. Ask for the sake of knowledge, but don't offer your limited imagination as proof against macroevolution.
[--In nature the apes were the kings, nothing was hunting them(so many fossils found) and they virtually did not change for millions of years in the fossil record, but suddenly 300 000 years ago or so, they changed into humans by some mysterious natural environment, doesn't seem bullshit to you?]
No it doesn't. Ape ancestors came in a variety of sizes and many of them, no doubt, were hunted. They also diversified (evolved) considerably. What we have today is but a small part of that family tree. At about 7 million years ago the hominid line branched off from the primitive apes and went through several million years of evolution--taking them from small-brained creatures to creatures with modern, human cranial capacities. The heavy evolutionary lifting was done by 300,000 years ago, but it seems that some important change did occur late in the game that made us fully modern in mind as well as body. At 60,000 years ago we start finding art, that also being about the time Neanderthal Man disappeared. But he isn't totally gone--we share some of his genes!
Where in this long process do you find a sudden change from primitive ape to modern man? No doubt many changes in the environment have played a role, so why do you imagine only one environment? Your idea of environment should also go beyond geography and weather to include interaction with other hominids and animals, with diseases, with plants. Why so much emphasis on environment when unimpeachable evidence for macroevolution is at hand? Please think about those things, the whole picture.
I apologize for the late reply.
OK... it seems this will be a long post so I posted it here instead.
@Greensnake
Thank you for taking the time to reply.
I have to admit that at least you did try to reply to "some" of the points I raised, but I am disappointed with the way you answered them.
1)First thing, it is basically evident in your claims that you fail to understand who has the burden of proof here.
2)Second, is that you seem to not understand how to support your claims.
I am the one challenging the claim of macro-evolution for evidence on some aspects of it's extraordinary claims.
You cannot do what my local priest does, when someone challenges your belief you cannot send him to read a book or a site.
Even though it might contain the answer, you should point out the answer and where it is located(not from a book but a paper.)
If you think you know something, then you should find no problem in quoting/referencing(papers) and finding the evidence that has been requested to support your claims/beliefs.
Ok, that being said I will now address the points you raised one by one in your first long posts.
"I believe (after reading many of your posts) that you don't really understand the fossil evidence for evolution"
It is possible, I certainly do not understand every aspect of them or even know more then 10% of all fossils.
Does that say anything about the subject at hand?
(1)NO, the burden of proof is on you to support your claim that macro-evolution(label) is supported by evidence.
", evidence that is absolutely decisive."
Please deliver the very best you have.
I am still waiting.
"I hope that you can read this book since it is one of the best books on the subject"
(2)thanks for the suggestion, I will try, but this is not the way you support your claims.
"Dr. Donald Prothero, with whom I made two trips, is a humble geologist of international fame who is associated with Caltech. He knows what the fossil record is all about!"
Now here lies the crux of the problem which hinders progress.
You thought that by mentioning this, it would make your belief more credible, and it truly does to most mindless people.
For me it says something like this:
"This guy might be influenced too much by fame/propaganda/bias to be scientific in his opinion."
Now I am not saying you are unscientific, but saying something like that in a mature debate does not help your case but it hinders it.
It is called an argument of popularity fallacy.
I do not care if the entire world believes in Jesus Christ, including the president and kings or the entire scientific community for that matter.
For true scientifically minded people, those petty things are insignificant.
"Also, you should try to follow up on the resources offered by Nyarlathotep as they are excellent."
I do not read troll posts, + if you think anything he said is worth mentioning, then claim it for yourself with proper quoting and referencing and we will check it out.
"Microevolution mostly refers to sub-species evolution, evolution within a species that does not go outside its borders. Macroevolution refers to evolution leading to new species, especially to higher taxonomic categories such as families or phylae."
They are terms that are not as fixed as most would want them to be, but I can agree with your label explanation, they were invented after Darwin postulations to distinguish the claims between the researchers when the research was still so young, thus the vagueness.
So we agree on the terms, where did you disagree with what I said on this subject?
"Therefore, there is no such thing as "microevolutionary theory" and "macroevolutionary theory."
yep Macro-evolution Theory does not exist in fact, only Micro-evolution or Evolution Theory exists.
Macro as you said is a label for a postulation(extension) of evolution(micro-evolution).
"Those words describe how much evolution has occurred, not how it has occurred. They are not important scientific terms, only terms of convenience."
Nope, Evolution theory DOES NOT describe how much evolution has occurred but IF it does occur.
Micro-evolution is the minimum type of evolution, the type described by Darwin in his explanation of how Nature Selects(evolution), completely explained in Natural selection paper.
Later researchers ascribed labels to "how much evolution has occurred" Micro and Macro.
Micro(the one Darwin explained well) is shown to exist and Macro(the one Darwin failed to explain), is still hanging.
"Microevolution mostly refers to sub-species evolution, evolution within a species that does not go outside its borders. Macroevolution refers to evolution leading to new species, especially to higher taxonomic categories such as families or phylae."
I do not see how this definition contradicts what I have said?
We are agreeing that they are labels introduced AFTER Darwin.
[If there should be a gradual change like Darwin proposed, why doesn't it appear in the fossil record?]
"It most certainly does appear in some cases!"
(1) Burden of proof.
+ If you go and read the punctuated equilibrium paper, it was attempting to explain exactly that question.
"Keep in mind that evolution proceeds most rapidly in small, outlying groups living under different environments."
(1)Evidence for it to apply to all species? Why not large groups under different environments?
"If a small group of plants or animals evolves for a long time, through many stages, and then becomes very successful and large, the fossil record will usually show fossils from the originally successful population followed by the later successful population."
We agree, the most successful are more likely to leave fossils then the less successful ones.
(1)But again this only means that you are failing the burden of proof for your claim and putting an excuse for it.
You cannot do that when trying to support a claim with evidence.
I can claim that the moon is made of cheese at the core and we don't have evidence because we haven't reached the core yet.
I am putting an excuse to cover the fact that I cannot support my claim.
"The in-between fossils, belonging to small populations in small areas, will usually not be found."
true but, you are assuming many things here, you are assuming that this applies to every situation the fossils are missing, which is not the case. In fact this excuse only holds if there is evidence to suggest that a specie is "belonging to small populations in small areas". Failure to show that, it means that punctuated equilibrium does not account for those.
Apart from that minor problem, punctuated equilibrium also has the problem of containment which you failed to address yet.
Apart from fishes in ponds how does a specie get a totally new environment and "is belonging to small populations in small areas"?
The "WHY" of the hypothesis is completely ignored thus not even reaching the level of a scientific Hypothesis for macro-evolution using punctuated equilibrium.
" That is one way to get a "gap" in the fossil record."
Yes of fishes in ponds, You again failed at showing how this applies to other species with an explanation.
"Conditions are rarely so good and consistent as to preserved a long series of gradual changes in the fossil record, especially for larger animals."
True, but a specie needs to be successful for enough time to adapt and evolve to an environment, and with enough time, it is bound to leave a fossil eventually like it happens.
This is why we found so many ape fossils, because they were everywhere and very very successful contradicting your point of
"belonging to small populations in small areas".
Apes were migratory creatures, they moved from 1 environment to the next, their body could survive most environments on earth.
It simply contradicts the idea of an isolated environment making drastic changes to a small group.
Apes(facts) simply contradict punctuated equilibrium.(their stasis does not happen in a contained small group thus the hypothesis is proven not working for all species)
"If you calculated the depth of earth needed to bury one horse fossil every 10,000 years, then another layer on top of that, etc."
Awc
OK first of all, I assumed you knew how fossils are made in practice, which seems I was wrong.
Fossils are made mainly in 2 main ways:
-Your body is buried in mud by a flash flood and you become a fossil.
-Your are attacked and killed by an animal and before the animal eats you, another bigger animal comes along and scares your killer and stumbles upon your body burying you in mud and the same process occurs.
Yes it is a miracle to become a fossil.
It is another miracle to find one without destroying it.
Basically it is a miracle on top of another miracle to preserve a fossil, but they do happen because of the popularity and time evolution takes to happen. Thus we should be able to see this evolution.
AND WE DO SEE IT for Micro-evolution, yet when it comes for macro-evolution we fail.
Which should be easier then micro-evolution, yet somehow we don't, and thus we have to come up with excuses like punctuated equilibrium.
After knowing this you should know why you should scrap the horse analogy. All you need is a horses dying in a flash flood, the layers of sedimentation will always happen if the horse is buried in mud.
So yes if horses became dragons, then it is very likely that we should observe this transformation in the fossil record given the long time needed for such a transformation to occur through Macro-evolution.
"However, you don't need every single step to see the trend."
(1)Not every step, but enough steps to serve as evidence to support the claim of macro-evolution.
Not enough steps have been presented for any specie yet, not even the fishes in the pond described by punctuated equilibrium.
"What you see statistically in the fossil record are the very successful species whose fossils have a chance to be preserved. You don't usually see the intermediate fossils left by small, rapidly evolving populations."
You are assuming there are intermediate fossils, it is your belief based on what you have been told.
If there wasn't at all, the fossil record would be exactly as it is right now.
Science works like this:
You go where the evidence leads.
The evidence seems to indicate that species just appear and intermediate species seem never to be popular enough to enter in the fossil record to the point that one can consider them to not exist.
Punctuated equilibrium does not account for any other specie except the fishes in ponds, thus it fails at helping the gap in the fossil record.
"Another possibility (as was true for some trilobites in New York) is that a species may do its evolving elsewhere before returning to the original home grounds, that being the location checked by the geologist. Therefore, new species often (but not always) seem to appear out of nowhere in the fossil record."
This is like debating a creationists where instead of having a god of the gaps argument, I am having a macro-evolution of the gaps.
(1) the burden of proof is on you to support such a claim.
It is an excuse for providing no evidence, that macro-evolution is even happening.
The Cambrian explosion is a problem because there is not enough time for the standard Darwinian evolution to happen and generate such an explosion of new species through adaptation of the previous species recorded in the fossil record.
Apart for offering no explanation of WHY it happened.
(1)Now you are claiming that it must have happened, but the burden of proof is on you to show that such a thing could even happen.
Remember a hypothesis is an explanation, and the explanation is simply not there.
I do think species evolve and change to adapt to environments, but claiming that new more complex species emerge form different less complex ones is pushing it.
It is like saying: since a car can move, it can fly too, ignoring the complexity of aerodynamics, weight distribution etc...
"By the way, the Cambrian "explosion" probably took 10 to 30 million years. It didn't happen overnight! "
It did happen Overnight in evolutionary terms. I thought we were having a mature debate and you would understand that statement since it is often used in the scientific community to mean just that.
"Just prior to that time the Earth seems to have been frozen over, and one idea is that it thawed to a degree that allowed life to take off"
Lol, yea nice explanation, soon we will hear that the earth burned to a degree that it allowed life to take off.
These are not even scientists, the drunk around the corner could come up with at least an explanation rather then a dodge.
This is not an explanation, you wish to say that if we thaw a piece of land from Ice NEW MORE COMPLEX species will just Macro-evolve in little time from SIMPLER older ones and then suddenly stop macro-evolving, but continue with the normal Darwinian evolution(part-stasis).
(1)Where is the evidence of this absurdity?
This is what I call making stuff up to fit a 140 year old hypothesis that contradicts the laws of nature that demand a reason for something to happen. New complex species do not magically evolve from simpler ones without reason in such a shot time and then stop sudenly, especially if the reason is the effects of a natural habitat not even explained.
"Another idea is that oxygen reached a critical level and allowed more complicated life to develop"
yea that did happen but no explanation is given how oxygen kick started a boost in evolution that was never seen ever again in history,
(1)Oxygen did allow for more complicated life true, but it did not do miracles. It does not completely transform new species, this has not been shown in labs to occur. The burden of proof is on you to show that oxygen does speed up evolution instead of just effecting evolution.
"We don't have the final answer, but there is no problem here for evolution."
True we do not have answers and not true, it does hinder Macro evolution since macro-evolution is trying to explain the origin of species and the Cambrian explosion is evidence that shows that something else happened in that case, NOT macro-evolution.
Thus a true scientist must look for other options that give an actual explanation.
"Since your knowledge of the fossil record is very weak, you should be careful about saying "there is no evidence.""
Well, if you think so why not provide the evidence?
(1)Remember I am the one doubting your claim, the burden of proof is on you not me.
You sound like my local priest when he says you do not know the entire bible(just claiming that I do not) to excuse him to discredit my argument and not providing the answer for my question.
I only asked for the evidence you are so confident that exists.
I am still waiting.
"My guess is that there is plenty of evidence, which would explain why punctuated equilibrium is widely accepted by biologists and paleontologists. Note that Stephen Jay Gould was not talking about "overnight mutations." He was talking about a period of rapid evolution driven by environmental pressure."
Overnight meant not in a single day, but in evolutionary terms, very very fast.
Human evolution from pre-humans is considered Overnight too since it is considered less then a million years at the moment by the scientific community. Not a single bone matches in just 1 million years.= Overnight.
[Fish are easy to isolate but how can you apply the same principle with apes which are migratory creatures?
It is true that mutations occur at a faster rate with interbreeding and sudden change of environment but Stephen Jay Gould failed at showing positive mutations to occur.]
"Mutation rates have nothing (little) to do with the environment or interbreeding!"
Really?, Are you saying that mutations occur less with interbreeding and sudden change of environment?
Because that would contradict all the facts we know about interbreeding mutations and also the latest evidence in mutations for bacteria which are direct result of environment changes.
It is basic knowledge that if everybody marries his sister/brother, mutation rates are higher.
If the environment changes eg; radiation field, mutations are also higher.
"It is natural selection working on existing genetic variability"
I did not say natural selection was not also involved or that it was not the main factor, I just stated that some other 2 factors increase the mutation rate, that you seem to agree with it here:
"driven by environmental pressure, that sets the rate (among other things). Interbreeding merely concentrates mutations already existing."
I don't even know why you even bothered to oppose that statement, it was the basis for punctuated equilibrium.
An accelerated micro-evolution that would not show up in the fossil record because of the little time for the intermediary species lived.(just 1 million years or so. "overnight evolution")
While you ignored completely the point that was relevant to the subject:
"Fish are easy to isolate but how can you apply the same principle with apes which are migratory creatures?"
"Of course positive mutations occur!"
(1)Evidence?
"How else did desert plants become adapted in wonderful ways to desert environments?"
God of the gaps?
Just because we do not know something, it does not mean, god did it, or macro-evolution did it, or that "positive mutations occur!"
That is not science.
About desert plants, you do not need fast positive mutations(punctuated equilibrium), instead one could use micro-evolution to explain a very slow adaptation/mutations to less watery areas of some plants. Even if micro-evolution could not explain it, it does not matter since it would be a god of the gaps argument.
I only claimed that "Jay Gould failed at showing positive mutations to occur."
You seemed to commit a straw-man fallacy here, and competently ignore the point I raised.
I know he failed to show it in his paper since he never even tried to show it, he postulated it as an assumption.
"I don't know what type of fish Stephen Jay Gould was studying, but I do know that fish fossils grade smoothly into amphibian fossils which grade smoothly into reptile fossils.
(2)Good finally something you think to know but again you fail to show the evidence for it.
[Stephen Jay Gould failed also to show how those new fish actually outlived the rest of the fish which was the basis of Natural Selection. Survival of the fittest.]
"There is no such requirement!"
Lol Natural selection, is riddled with the idea/explanation that the fittest in the environment survive and the rest eventually die out, thus the species evolved to fit better that environment.
It is the explanation of how Natural Selection occurs naturally in nature.
If you do not know about that you need to read Natural Selection.
Then after the survival of the fittest happens one has to show how the new specie managed to become the majority when reunited to the rest of the world.(sea/river)
The small fish in the pond did not explain how they become the majority, thus punctuated equilibrium does not explain the facts that apes went extinct while humans did not. (new specie shows up in the fossil record while old ones disappear)
How did a more adapted to nature specie go extinct compared to a specie adapted to a particual environment, not the most common one?
When the fish in the pond joines the rest of the other fishes in the sea/river, how did those fare against a more adapted fish at sea/river?
How did the fish of the pond(the end result, new specie) show up in the fossil record while the older ones go extinct?
Basically how does punctuated equilibrium explain the gap in the fossil record compared to the extinction of older and more adapted to the usual environment?(I know that not all the older versions go extinct but some do and punctuated equilibrium makes a contradiction when this happens)
"You need to hit the books and gain a basic understanding of evolution. "
Seriously man, stop making claims about me that you constantly fail to support.
It does not help your case at all.
"Most evolution is a branching out process that does not require the extinction of the original population."
I did not say it requires the extinction or that the less fitted MUST die out, but they should die out in the new environment according to Natural selection prediction. A theory is a prediction.
NATURE SELECTS the ones who will survive in a particular environment.
(the ones that remain in the old environment should survive though, assuming the old environment still exists)
"(An excellent, beginning book to read is: "Undeniable" by Bill Nye (known as the science guy in the U.S.).)"
Books are interpretations of the papers, you should start reading those instead, look at the references of the books, and compare the references with other papers. Check the authors papers own remarks and criticisms.
"Today, Punctuated Equilibrium is widely accepted among biologists and paleontologist because it explains so many facts. To better appreciate it you need to study a good site on the Internet."
Lol man seriously, I pointed to you contradictions in Punctuated Equilibrium that do not explain the facts which you ignored.
A hypothesis(explanation) should explain all the facts, it does not, and that is why it fails to support macro-evolution.
"Punctuated Equilibrium explains a lot of facts, especially why new species "just appear" in the fossil record without links showing a gradual change."
We agree it fits some of the facts(no intermediate fossils) with its stasis hypothesis(explanation), but fails in presenting the hypothesis of the sudden explosion of new species that occur in the Cambrian explosion.
The failure in presenting an explanation for those species is the problem.
How do species which are not trapped fishes suddenly stop the stasis period and decide to do a rapid macro-evolution?
Remember the trapped fishes did only a rapid/fast Micro-evolution not even a macro-evolution.
He did not even show how or why the fish in the pond became a reptile or something in his paper.
Also fails to explain how the stasis seem to be happening all at once for all species just after the Cambrian explosion which is also very unlikely.
"Why wouldn't evolutionists want to address scientific problems in their theories? Isn't that what Darwin did, something that all good scientists do?"
Not if politics is involved and too many people have their job/reputation based on it to give it up.
You need to look at the scientific community to be as dogmatic as a church, to understand why all of them(100%) would go and persecute the Wright Brothers when they proved mathematically that humans can fly in their scientific paper. The scientific community came up with papers and mathematical formulas to discredit them, and this kept going until finally they managed to built the first plane themselves.
Also the reason why 98% of the scientific community was also against Darwin when he published the paper Natural Selection for 10 whole years until the creationist used politics to try and teach creationism in schools. Suddenly Darwin's hypothesis became a better alternative, not because it was scientific but because it was convenient to them at the time.
Since then we have been repeating the same things over and over again regardless of all the new conflicting evidence we find.
Darwin was a good scientist, but most in the scientific community are conformists, they are fans of what they learned, they found jobs because of papers they published on what they learned.
If someone comes along to show that their papers are based on nonsense, they might lose their reputation and jobs.
That is why they are mostly not really scientists that care for the truth but care for themselves first.(human trait)
There are good scientists but most of them fear ridicule and persecution from the establishment, and one cannot blame them if they just ignore the subject entirely. It is a career breaker not a maker for sure.
It is up to the people who care about the truth to be scientific and challenge the dogmatic views with intelligent questions so there could be progress.
"The shape of the adult human face is that of an immature chimp's. "
LOL this was awesome.
Did you know that; that cannot happen for the simple fact that chimps have so many different things.
-Huge brow ridges compared to humans
-Circular eye sockets compared the the squarish eyesockets of humans
-Huge chin, sticking out of the face where humans don't.
-Nearly flat nose, huge nose cavity where humans have a small cavity with a nose sticking out.
-Chimps have low and small forehead while humans have a huge forehead as if it hit a truck or something.
So yes, you would be right if you give that poor human a hell of a beating in the face to completely restructure the bone of his skull, then you might not distinguish him from an "immature chimp" when he is still an embryo lol.
One should not rely on interpretations.
You should have said that IT WOULD LOOK LIKE an immature chimp's for someone who doesn't know anything about the subject.
If you know what to look for, it is very clear what a chimp looks like and what a human looks like.
The younger a specie is, the more similar it is to other species, that does not mean at all that other species could have evolved from it, thus it is not evidence for macro-evolution of apes to become humans.
When you go eat a rabbit at a restaurant, the chef could cook you a cat and it does indeed look like a rabbit when it is served, unless you know what to look for.
Did the rabbit evolve into a cat?
This is the kind of evidence you are presenting to me and it is not evidence.
Evidence is when one looks at the bones and compares similarity in detail(structure, thickness etc..).
"If you can't, I can try to help you."
Yes, it be nice to see how they mange to transform an chimp head into a human and leaving it as a chimp.
"You mean they are stumped at what to label them?]
Yes."
That was irony on my part, as if anyone should care about the label we give them.
One should focus on the differences, labels change when new conflicting data arrives and when most are of the same OPINION about the change.
"Some fossils may be hard to distinguish from others because of the reasons you cited. Usually it is not a problem since multiple fossils are usually available and, in some places, even whole."
yes but how does this support your point that this is somewhat evidence of macro-evolution?:
" paleontologists are stumped as to which side of the line to place a fossil"
I see it evidence for micro-evolution and the confusion is for the reasons you and I discussed.
I will reply to the other post in a new post since this one is become too long.
(I have not even read the other posts)
I apologize for mistakes I might have made that are addressed in the other post but I don't have time to reply to it so I won't read it else I could not resist to reply.
(1)In short you need to provide the evidence for your claims instead of sending me to read books(/entire sites) hunting for the evidence relevant to your claim.
That does not mean I would not try and get those books but it would be for my own research not to try and check if your claims are supported.
Jeff - "You need to look at the scientific community to be as dogmatic as a church, to understand why all of them(100%) would go and persecute the Wright Brothers when they proved mathematically that humans can fly in their scientific paper. The scientific community came up with papers and mathematical formulas to discredit them, and this kept going until finally they managed to built the first plane themselves."
That is a myth that is popular among crackpots and conspiracy theorists; sadly I'm not surprised to hear it from you, but it isn't true. Furthermore it isn't even possible to prove either case mathematically; that alone should scream myth to anyone who is not credulous.

"I thought I'd try to answer some of your previous questions."
I will reply to all the answers to SOME of my previous questions.
It is important to note that all my questions must be answered to make the claim that the hypothesis is supported by logic/science, not just some of the questions.
Everybody can pick and choose what to ignore when he knows he cannot support his claims.
"Early ape and hominid fossils are rare!"
Not really, all fossils are rare, but apes are one of the few species which we have quite a few. But it is true that some parts(eg: the feet, are indeed rare since they are the hardest to preserve).
"All are extinct now except for one member of that family--us.)"
That is an assumption, since we have, not found any yet, and since 1/3 of the deep wooded areas of the planet was never foot surveyed once, it is a pretty bold assumption.
These are migratory creatures, that can smell and hear anything a mile away.
Claiming they are extinct because we haven't found them yet is an assumption.
Also fossils are not made in deep forests since anything that dies there gets recycled by nature.
The Panda is a fine example of how easy it is for us humans to not know about an existing specie. (took us 60 years to find it after knowing it was there)
"The necessary quick burial in sediment is hard to come by."
"Nevertheless, over the years a considerable number of hominid fossils have been found."
As I said in my previous reply, fossils are usually made when an animal is buried in mud, and apes were everywhere and in huge numbers else we would not have found so many fossils of them.
Yes fossils are incredibly hard to find, but luckily for us, apes where everywhere since nothing was hunting them, thus eating and reproducing for millions of years shows up in the fossil record.
They could take out 2 lions with ease(the human size ones).(each was around 10 times stronger then a human)
Their Micro-evolution also shows up in the fossil record, it is their Macro evolution(going to humans) that is completely missing.
Thus the evidence is simply not there.
"The older hominid fossils show a distinct mix of human and ape characteristics."
Where? What characteristics?
"Did you know that some human populations have a significant number of Neanderthal genes?"
Yes, so what?
Showing that Neanderthals are somehow related to us, does not show that we macro-evolved from their ancestor, or that they macro-evolved from an ancestor at all.
It just shows that we and Neanderthals are compatible enough that somewhere along the line in history a Neanderthal could have mated with a human and their genes appear in some humans.
Extrapolating that, to support the idea that we share a common ancestor is pushing it.
Our DNA is different, drastically different, maybe we can mate like a donkey can mate with a horse to produce an offspring that can reproduce(unlike the mule).
There is the story of ZANA, a possible Neanderthal that was captured by a Russian tribe(1890's) and they used her as a sex slave.
She bore children and one of them was excavated.
His skull looks like a Neanderthal skull.(more ape-ish)
https://exemplore.com/cryptids/Mystery-Files-The-Story-of-Zana-Do-Neande...
"In Darwin's time the hominid fossil finds were practically non-existent."
Actually they were coming at a faster rate then expected.
Though compared to what we have found after 150 years from his paper one could say your phrase.
"I'd like to see what he really said."
I did not quote him, I summarized what he estimated but I won't be bothered to go dig which paper/letter did he make that estimation since it does not hinder my point at all which you did not even address.
150 years looking really hard for a very specific something and coming empty handed is absence of evidence to support the claim.
Just so we are on the same page, here are some quotes that show how much lack of evidence there is, and if you wish to say that by now we found new evidence then please present it.
"Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such finely graduated organic chain; and this, perhaps is the most obvious and gravest objection which can be urged against my theory."
Charles Robert Darwin,
The Origin of Species: The Preservation of Favored Races in the Struggle for Life, 1st edition reprint.
“The extreme rarity of transitional forms in the fossil record persists as the trade secret of paleontology (study of fossils). In any local area, a species does not arise gradually by the steady transformation of its ancestors, it appears all at once and fully formed."
Dr. Stephen J. Gould, Prof of Geology and Paleontology, Harvard University. Mentioned in one of his regular columns in Natural History Magazine (1977) and also in The Panda's Thumb, 1980, p. 181-182
"The record certainly did not reveal gradual transformations of structure in the course of time. On the contrary, it showed that species generally remained constant throughout their history. New types or classes seemed to appear fully formed, with no sign of an evolutionary trend by which they could have emerged from an earlier type."
Bowler, 'Evolution: The History of an Idea', 1984, p. 187
"http://evolution.berkeley.edu and http://www.talkorigins.org
Talk Origins has a lot of good material, some of it dealing with evolution."
As I said in my previous post to you, you need to properly support your claims and understand the burden of proof.
Even a priest can send me to read the bible on bible hub claiming that it "has a lot of good material, some of it dealing with evolution."
"Enough fossils and other evidence will make the case--even without knowledge of the environment. "
That right there is faith.
That is not science.
First of all there ISN'T even a single fossil that could NOT be explained by something else, rather than a transitional fossil of macro-evolution.
Second, even if you find the transitional fossil, not knowing HOW this transition occurs or WHY, means only that MYSTERIOUSLY a specie similar enough to look like a transition, appears in the fossil record.
This is like saying, "OHH wow one person is sick and now another person is sick, so demons exist."
"Enough" sick people "and other evidence will make the case--even without knowledge of the environment. "
If you can see the "Not a Cause for a Cause" fallacy in the demons analogy, you should see the fallacy in your macro-evolution.
https://bookofbadarguments.com/
"Perhaps that had something to do with the evolution of upright humans."
You were wise to use the "Perhaps" here, because the hypothesis presented for upright walking always was ridiculous.
Fist of all there is no evidence that apes did not walk upright from start.
But during Darwin times upright walking was considered a human only trait.(dogmatically)
Today scientists are at least accepting that walking upright is no biggy, it does not give us any advantage unless we are climbing trees which went against the Savannah hypothesis and also problematic since the apes/monkeys are better at climbing trees then us.
You should look at the aquatic ape hypothesis, it is an eye opener for people truly interested to find the truth on this subject.

"[When it comes to scientific papers the evidence in them falls short to 0 my friend.
But I would be happy if you prove me wrong. This is a subject I have huge interest in.]
I must completely disagree! As I mentioned earlier, over the years quite a few hominid fossils have been found and they all get reported in various scientific journals. Please read Dr. Prothero's book and decide whether the evidence is still near zero"
I asked for scientific papers and the evidence they present.
I do not want to go and read an entire book to find the evidence you think it contains.
If you wish to claim that there is evidence because you know there is evidence, then quote and link me to the part of the paper that supports your claim.
Burden of proof.
"How are they proof of macro evolution?]
Dr. Prothero describes the case for the giraffe nicely. In the giraffe the laryngeal nerve is an incredibly clumsy "design" that actually can endanger the giraffe to some extent.
yes I had this subject raised already when Richard Dawkings used the giraffe dissection to show something like this.
It only shows how much we do not know about the brain and it's connection to some organ functions.
The "laryngeal nerve is clumsy" because we do not know yet why it is like that, we think it is clumsy if we assume macro evolution caused a clumsy evolution, like the appendix in humans (not working).
This is not evidence of macro-evolution, but only a possible explanation of such occurrences assuming macro-evolution.
NOT THE ONLY POSSIBLE EXPLANATION.
An easier expansion is that they serve a function we have not yet discovered like what usually happens.
A more easier explanation is that we do not know yet why some organs stop functioning.
(Evolution can sometimes recycle a vestigial organ for another purpose.)
LOL
Wanna see you supporting that claim.
"another purpose" Like what?
You know how ridiculous that claim is?
or you believe everything they claim because they say it?
"If an animal has a vestigial organ that only makes sense in a wholly different animal, then that is prime evidence of macroevolution."
What?
It only shows that the animal is a wholly different animal.
We humans have an appendix which is not working, other animals(apes) have it working= evidence that somewhere along the line our appendix stopped working/or was never working.
It is not evidence that we evolved from other animals.
It is evidence against macro-evolution actually, it shows clearly that we are different, we have a very important survival organ not working which all other animals have it working to survive.
It shows an anomaly that does not happen in the wild.(in the natural environments we know of).
We should be adapting to 1 or more of those environments not be worse at them.
Evidence against macro-evolution and that is why they don't popularize much about it.
"Indeed, whale fossils trace back to a four-legged river animal"
I could come up with 100's of other possibilities for "vestigial remnants of hind legs" on whales.
As I said those can be dismissed as a completely different species unless you find the transitional fossils to show that one is slowly evolving to become the other.
We see the fossil of a tiger and then we see the fossil of a cheetah, they look similar but the structure is different, just because we know the structure of a dog/wolf, we know that the cheetah is not related to the tiger, else we would say:
Look how similar they look, even though the legs are a bit off, macro-evolution happened, speed was in damand and the tiger evolved into a cheetah (dog type of legs).
Why not say it is a different specie when we see the same thing happening to a whale?
Can a whale have legs/flippers without we imposing our explanation that it must have been a land animal before?
This is bias.
This is no evidence at all.
Who said that the back flippers are "vestigial remnants of hind legs" as a fact?
They could have served a purpose before some catastrophic events that shaped the entire planet and then micro-evolution could have made them inert or extinct, while others without "vestigial remnants of hind legs"(flippers) survived.
I grant that macro-evolution could explain the situation but it is just 1 of many possible explanations.
This is not evidence, it is speculation.
"[Yea that is what Darwin proposed in his paper:
"NATURAL SELECTION" (postulated micro-evolution )
Then he made another paper named:
"Origins Of Man"(postulated macro-evolution)]
As I mentioned in a later post, and I think it good to repeat it here, microevolution and macroevolution are not explanations.They are labels."
Labels of explanations, explanations of:
"Microevolution mostly refers to evolution that does not go beyond the species level and it results in sub-species, varieties, or just some small changes. Macroevolution refers to evolution that has exceeded the species level, especially evolution that has exceeded the higher taxonomic levels."
You just EXPLAINED what the labels refer to.
"They are words of convenience and not important scientific terms."
Yea we agree, and that is why I am using them, and so are you.
"Darwin's first book identifies natural selection as the main engine of evolution."
True
"Today, we know that there are some other factors at work,"
Nope, we don't know, we expanded on that theory and came up with new ideas that add to it, than and we gave them labels.
"but natural selection is still the main engine."
True, but you cannot call natural selection if you don't explain the natural selection part can you?
What natural habitat selected a particular specie?
"Natural selection applies to human evolution as well,"
Nope it does not, they claim it does, yes.
What natural habitat selected humans out of the other apes?
AHH, you cannot follow the paper now!, can you? since it is a different claim based not on the science of Darwin, but on a label called macro-evolution that gives NO explanation, NO SCIENCE.
Just believe it, and your sins are forgiven.
"but Darwin (already fearing loud protests) saved the matter of human evolution for a much later book."
That is your humble opinion, he did certainly fear protests and it was wise of him to go baby steps with things which are based on evidence first before putting forward things which are not based on evidence.
" Darwin is not offering two different theories in his two books. He offers one theory that applies to two subjects."
No, they are different claims and deserved 2 different papers, the latter is however assuming the first as an assumption.
Darwin first proposed the idea of evolution(it exists), then he proposed the idea that human origin could be explained by an evolution process.
Darwin just proposed the idea which is very scientific, but people that think that both claims are the same thing are wrong and commit this fallacy:
A Not a Cause for a Cause Fallacy
https://bookofbadarguments.com/
"But it is the truth! "
Missing links are not what you think you are, I have explained them and you did not address my explanation at all, and instead you just insist that my "definition of a missing link is not the point."
"We are concerned with a paleontologist's understanding of a missing link."
Again an argument of authority fallacy.
I explain why some subjects are not touched or even admitted in my previous post.
(politics,money, power, job security, pride, fame)
The idea that the scientific community is immune to these things is patent nonsense, it is dogmatic as a church especially on a subject that creationists are so heated upon.( a 150 year war)
They would prefer to say nothing rather then say a word too many, that might cost them their job.
"an "evolutionary tree" diagram! "
Yes we agree, that is a micro-evolution, there should be no big changes there.
EG: types of bees.
"This is the primary prediction of macroevolution!"
NO NO NO NO
This only shows Micro-evolution, it should not predict that some branch will eventually completely change.
It does not predict that a honey creeper will eventually(with enough splits) will become a crow.
You will always have a split which would survive in the environment which is in, unless the environments demands it, there should be little to no change(stasis).
"There is no way to get such a diagram without obvious fudging unless life arose from primitive cells."
WHAT?
I say "obvious fudging" is the business of the day, since no evidence what so ever was presented to support any of the claims.
primitive cells???
Where does the "primitive cells" come into?
Man seriously you need to study the subject more because you are taking assumptions that have been hammered in your head as facts and you are not making any sens.
There is no link between "primitive cells"(like prokaryotes) and basically any other specie/bacteria on earth.
There is to this day no explanation supported by evidence for their macro-evolution.
Why did they change when for millions of years they remains virtually the same?
Infact some scientist would admit that at least one of the prokaryotes could have come from a meteorite, since 2 different types of prokaryotic bacteria appear on earth virtually at the same time and that contradicts how Abiogenesis or evolution should happen.
"(Life might have begun with a number of different cells in different locations, but one line survived and all life today bears its stamp.)"
Seriously you did not even explain anything in that statement.
I bet the book of Mormon gave a better explanation than you did.(never even read it)
What stamp? seriously just take the prokaryotes and try to imagine how the hell did the cell nucleus come from the prokaryotes by a natural environment?
How do you get something so complex that we can beryl replicate it from scratch by some random effects of the environment.
If we had their stamp, then we would not have cell nucleus but just prokaryotes.
What we have instead is the same prokaryotes + a lot more stuff.
"no reason in the world for thinking that unrelated life forms would all use the same DNA code."
The key is "in the world"
Living on the same planet is a very valid reason why we would have very similar structure and DNA.
Maybe only the ones with that type of DNA could survive on this planet.
["DNA has proven that were are all descendants from the same single cell."
Nope it did not, where is this proof?]
You still did not give me any proof but just a very bold claim, that it must have happened.
Just because you don't know how or why it happened.
"It's true that prokaryotes (bacteria, for example) don't have a nucleus, but they still have DNA which often forms a loop in the cytoplasm."
Yes, but you are claiming that somehow, after millions of years, Prokaryotes become Eukaryotes naturally(miraculously).
No cell nucleus went to very complex cell nucleus just like that, nature can do everything.
No explanation needed, just believe it.
The truth is that both the Prokaryotes and Eukaryotes just appear in the fossil record with no transitions in between.
Your explanation is not supported by evidence. it is a nice idea if the fossil record shows what you are claiming, since it doesn't, throw it in the bin already and start looking for an actual explanation that fits the facts.
"What hasn't been found (yet) is a clear pathway from non-living to living."
Yes, finally we agree on something, how does it feel when you don't know something?
Is it not better to accept it, instead of trying to defend a claim which is indefensible?
"that you could probably switch the two and never know the difference!"
Yes we are all carbon/silica based lifeforms I know, it does not show macro-evolution.
Just because Cytochrome-C are so similar it only means that we both do survive on this planet, and thus similarities are bound to arise.
This is like comparing cats and dogs and being amazed that both have 4 legs and have have hair.
we can study the similarities and differences between the cytochrome-C of different species, and the same "evolutionary tree" relationship (with only minor differences) pops out! If not evolution, then what?
I have not studied the cytochrome-C in particular so I need a bit of clarification here.
Is this video representing your evidence?
https://www.youtube.com/watch?v=RLV_fSXO6So
So you are saying that the difference pattern in mutations of cytochrome-C follows the evolutionary tree pattern right?
Well that is not evidence of macro-evolution but evidence that cytochrome-C has been effected by those mutations throughout history in those species tested.
About the video claim of inheriting it from our common ancestor:
Yes it is a possible explanation but not the only explanation either.
It is one of the few times where the hypothesis conforms to the facts, it is not evidence though.
I could make a claim that I can fly since I know the earth is a sphere, how else would I know it is a sphere?
Therefor my knowledge is evidence for my claim that I can fly.
See the fallacy there?
It is one of the few times where the hypothesis(flying) conforms to the facts, it is not evidence though.
"[It was shocking to me that almost all papers just refer to Darwin original paper on the subject as a reference and just move on the specific area they are building a hypothesis on.]"
"Are you kidding me? Modern scientific papers would have no reason to cite Darwin unless it is an historical note."
No I am not, most papers whenever they use macro-evolution(assume it) they just put Darwin's paper as reference, with no explanation of how it works.
"If you are a scientist you cite the most recent research relevant to your paper. "
Yes you would, but when you go and look on that paper to see where it is getting the evidence to support its claim, you notice that they all assume macro-evolution and cite a paper which cites another paper, etc.... until you finally reach the paper referencing to Darwin's.
"Sorry, but you don't speak for me! Elsewhere--very briefly--I have given the main proof for macro-evolution, i.e., evidence that has no reasonable alternative interpretation."
Lol I can come up with an alternative not supported by evidence in less then 5 seconds,
You have not presented evidence, much less proof.
"The fact that you cannot imagine how something happened is not an argument against it!"
You sound like my local priest.
"The fact that you cannot apply logic to god is not an argument against god."
If I cannot imagine it, it means it is so illogical that nature does miracles that no one can imagine it.
Isn't that what we call the "argument from ignorance?"
Argument from ignorance is when, one does not have the information and makes a claim.
Here the one making the claim is the guys that think macro-evolution happens without having the information to claim it.
I am just a skeptic and asking for evidence for the claim.
I am still waiting.
"At one time not even the best scientists had the slightest clue as to what made the sun shine."
I could imagine what makes the sun shine and I'm sure most people could imagine flying with bird feathers.
"Ask for the sake of knowledge, but don't offer your limited imagination as proof against macroevolution."
Burden of proof.
I offered nothing, I asked for an explanation since you claimed it is part of the theory of evolution and you failed at delivering it.
I also failed at trying to find one, by trying to imagine it and thus stated why I did not believe such nonsense.
"No it doesn't. Ape ancestors came in a variety of sizes and many of them, no doubt, were hunted. "
Straw-man?
I though we were mature enough to understand that we were talking about the human sized apes here, since we were talking about human origins.
"The heavy evolutionary lifting was done by 300,000 years ago,"
lol you mean complete transformation?
"At 60,000 years ago we start finding art, that also being about the time Neanderthal Man disappeared."
Nice picture but that does not mean that 300 000 years before they did not have art too, this is speculation.
30 000 years ago is the last neanderthal fossil/tools if you ignore the ZANA story I mentioned above.
"But he isn't totally gone--we share some of his genes!"
You know that before year 2000 the scientific community believed that we humans evolved from Neanderthals right?
Then DNA proved them wrong and they came up with the common ancestor and we are still stuck with it to this day.
This time they won't name which one though, lesson learned.
People will believe they know what they are talking about anyway so why bother.
"Where in this long process do you find a sudden change from primitive ape to modern man?"
100 000-300 000 BC cro-magnon(humans) seem nothing like the other apes.
"No doubt many changes in the environment have played a role, so why do you imagine only one environment? "
For evolution to take effect you need a long period of time, the time is simply not there, not even for 1 type of environment to make such changes to the body structure, more then 1 is even less realistic.
"Your idea of environment should also go beyond geography and weather to include interaction with other hominids and animals, with diseases, with plants."
The environment includes all those things.
1 environment justifies some changes or all the changes at once if need be.
The more different environments claimed the more time is needed.
First the specie is exposed to 1 environment and then to the other one, or both together if they are compatible(unlikely).
"Why so much emphasis on environment when unimpeachable evidence for macroevolution is at hand? "
You have provided no such evidence, only some aspects that seem to make macro-evolution conform to some of the facts.
Why are you ignoring the explanation when it is the basis of every scientific hypothesis?
"Please think about those things, the whole picture."
A whole picture:
You have a specie which is not adapted well in any natural habitat currently known on earth, but they claim that he does come out of those habitats somehow.
They never explain how though, so we must accept it on faith.
I am sorry, if one wishes to claim he is scientific one must use the scientific method and explain what happened, else admit that he does not know what happened and not just claim it must have been evolution since nature can do anything.
Claiming that evolution did it without an explanation, is like saying that god did it because god can do anything, and I cannot accept that, since it is not science.
Jeff Vella Leone (5-20-2016 13:23 and 5-24-2016 01:34)
Jeff, thank you for your two posts. Because of their extreme length, I'll gather a selection of points that I feel are more or less central to our discussion and, no doubt, a few others. A lot of material has been left out because it was either repetitive, of minor significance to our discussion, wild speculation, or (quite often) because it was impossible to understand what you were saying. (You need to expand key replies so that each idea gets developed properly and leads smoothly to the next point.) Perhaps, English is a second language for you. Sorry if I am a little rough in places but I was appalled by some of your statements. If you feel that I missed something really important, please bring those few items to my attention after carefully rewriting them. And, thank you for this excellent source: https://bookofbadarguments.com/
To avoid reader fatigue (you poor guys out there who are trying to follow this!) I will post my reply (over a few days) by sections, each section dealing more or less with a particular sub-topic of my discussion. The first post will be about what is proper in our search for truth. When all of the material is posted, I'll then I'll address some of the latest comments.
ARGUMENTS ABOUT HOW TO GET AT THE TRUTH
Jeff, keep in mind that this is a forum! I can give you a broad overview of the decisive evidence for macroevolution, answer some specific questions, demonstrate its power by asking other questions, and defend evolution (macroevolution) against your specific objections, but I'm not going to write a textbook for you! I'm not going to dig up endless references for common, scientific knowledge that was established many decades ago. Even if I had the time, I would not waste it by duplicating any of the excellent works already in existence.
If you want to see a book-sized explanation that goes into endless detail, that gives lots of references, I can recommend books for you to read, books that are not so simple (or so advanced) as to waste your time. If you have less time, then study some of those excellent Internet sites that you mentioned instead of mining them for quotes! (http://evolution.berkeley.edu and http://www.talkorigins.org)
[[It is important to note that all my questions must be answered to make the claim that the hypothesis is supported by logic/science, not just some of the questions.]]
[[1)First thing, it is basically evident in your claims that you fail to understand who has the burden of proof here.]]
Not true! Suppose a flat-earther used the same logic and declared that his long list of questions all had to be answered in order for you to make the claim that the spherical earth hypothesis is supported by logic/science? Is that a sound argument? Nope. If the evidence for something, such as a spherical earth, is so overwhelming that virtually all experts take it as established knowledge then it is fair to say that it is supported by logic and science even if ALL of a doubter's pet questions are ignored. Regarding macro evolution, most attacks by far are based on straw men versions of the fossil record, of evolution, or deal with insignificant details and irrelevant points, or have been answered many times already. Serious questions will rise to the attention of the scientific community (sooner or later) and be presented in the scientific journals, which allows other scientists to test them or plan further research.
As for scientific support, we need only note that the scientific debate has been over for a long time! Neo-Darwinian evolution (also called the Modern Synthesis) is now central to modern biology. (Neo-Darwinian evolution arrived when Darwin's ideas were united with modern genetics circa the 1930s.) Take a look at any textbook on general biology used in the great universities of the world--or any university, or college, or city college, of merit. Show me recent issues of "Nature" or "Science" (the leading scientific journals in the English language) that feature any "debate" over the basic fact of evolution.
I pulled 3 copies of Science out of the closet (29 Apr 2016, 6 May 2016, 13 May 2016). There is no hint of a debate over the fact of evolution. The May 6 issue has an article (under "News") relating to the size of the human brain. Humans are viewed as "high-energy apes." Another article (under "Research") deals with an aspect of primate evolution. In the May 13 issue we find an article (under "News") relating to the evolution of the Venus Flytrap. An article relating to the insights of molecular evolution, and another relating to the origin of life, may be found under "Research." I could waste even more time by pulling out even more copies of Science, but I think the message should be clear enough. In the scientific world evolution above the species level (macroevolution) is treated as a settled issue. It is the starting point for today's research.
You are the one who is trying to overthrow long established knowledge, meaning that you have to do more than pose questions and riddles as creationists do. The burden of proof is on your shoulders for the same reason that it is on a flat-earther's shoulders. At some point a scientific debate often reaches a firm conclusion after which it would be silly to continue rehashing old arguments. After that point, if someone wants to object, they have to convince the scientific community that they have a really hot argument. That is, the burden of proof is on the shoulders of those who challenge accepted scientific knowledge (knowledge that has passed rigorous tests). They must show that their objections have not been answered already, that their article reflects accurately (and acknowledges) the known data and theories, and that their objection destroys a central pillar upholding the accepted knowledge. Do all that and you can be another Einstein or another Copernicus!
[[You cannot do what my local priest does, when someone challenges your belief you cannot send him to read a book or a site.]]
Dr. Prothero's book "Evolution: What the Fossils Say and Why It Matters" is offered as a summary of the evidence demonstrating the wealth of the fossil record and its obvious support of macroevolution. Dr. Prothero lists numerous fossils and their observed relationships in geologic time and similarity. Many of those fossils are illustrated. I made my arguments and I referred you to this excellent summary of the evidence. Nothing wrong with that! Referring to a body of factual evidence is not a cheap substitute for reasoning! (Yes, some people do have a habit of referring us to this, that, or some other book or source when they run out of gas. I fully agree with your feelings on that matter, but that is not the case here.) We're talking about a data reference.
Bill Nye's book "Undeniable: Evolution and the Science of Creationism" is offered as easy (but excellent) background reading to get you up to speed on what evolution is really all about. (Some of your questions and points led me to believe that you might benefit from this book.) It is not a substitute for any of my arguments, but it may help you understand them.
[[Everybody can pick and choose what to ignore when he knows he cannot support his claims.]]
Am I ignoring something important? I am interested in the truth, but I really don't have the time to address every point you choose to bring up in lengthy posts, especially if they are impossible to interpret. Perhaps you might point out the most important (few) points that you feel are being ignored. Then, take the time and space to state them clearly so that they have smooth transitions between their parts. I shouldn't have to guess at what you're saying.
[[If you think you know something, then you should find no problem in quoting/referencing(papers) and finding the evidence that has been requested to support your claims/beliefs.]]
If a point is central and sources hard to find, then that would be the thing to do. Yes, we could agree on that. If it is widely accepted by the experts, then I don't always feel a need to dig up some token quote. When debating Bible-believers I often point out that serious Bible scholars reject the notion that the Gospels are eyewitness accounts or even historical narratives. Usually, I don't bother to dig up any quotes for this common fact unless pressed. Finally, I might be offering a point as general information and not anticipate that it would become a debating point.
[["Also, you should try to follow up on the resources offered by Nyarlathotep as they are excellent."
I do not read troll posts, + if you think anything he said is worth mentioning, then claim it for yourself with proper quoting and referencing and we will check it out.]]
Nyarlathotep offered excellent sources! Why do you disparage them by calling them "troll posts"? Judging by many of your questions and arguments, you definitely need to study them along with Dr. Prothero's book.
[["You need to hit the books and gain a basic understanding of evolution. "
Seriously man, stop making claims about me that you constantly fail to support.
It does not help your case at all.]]
Fail to support? Half this post is spent correcting your basic misconceptions about evolution! That's why I have recommended several books for you to study. It would be nice to begin a discussion without having to review the basics every time. Maybe this is a good time to ask you about your scientific background. What background do you have?
[["(An excellent, beginning book to read is: "Undeniable" by Bill Nye (known as the science guy in the U.S.).)"
Books are interpretations of the papers, you should start reading those instead, look at the references of the books, and compare the references with other papers. Check the authors papers own remarks and criticisms.]]
Research papers would be hard for a layman to read and they are very narrowly focused. Most people would not get much good out of them. Bill Nye's book covers all kinds of common misconceptions about evolution in a very friendly way. Having encountered many such misconceptions in this discussion, I really do think that you would greatly benefit by reading it. It looks like such a fun book that I may read it myself even though few things in it would be totally new to me!
[["Why wouldn't evolutionists want to address scientific problems in their theories? Isn't that what Darwin did, something that all good scientists do?"
Not if politics is involved and too many people have their job/reputation based on it to give it up.
You need to look at the scientific community to be as dogmatic as a church, to understand why all of them(100%) would go and persecute the Wright Brothers when they proved mathematically that humans can fly in their scientific paper.]]
Scientists make a habit of addressing possible problems in their papers because if they don't other scientists will. Also, it's a matter of courtesy to anyone planning similar research or follow-up studies.
Sometimes scientists may be slow in accepting something new, such as Darwin's evolution or Einstein's relativity, but that is only temporary. Maybe you should meet a few scientists as I have. They are not nearly as dogmatic (on the whole) as you believe, and the great majority of them became scientists to explore the unknown. Moreover, no good scientific journal would accept a paper from a scientist who makes no effort to identify weaknesses in his or her hypothesis. Scientists win awards by finding errors in accepted ideas, not in defending them!
[[Also the reason why 98% of the scientific community was also against Darwin when he published the paper Natural Selection for 10 whole years until the creationist used politics to try and teach creationism in schools. Suddenly Darwin's hypothesis became a better alternative, not because it was scientific but because it was convenient to them at the time.]]
You're kidding, right? You must be joking! Please tell me that you are joking! This is an idiot's tale. You don't want to go there. Scientists rejected Darwin at first because the scientific community, itself, was almost entirely creationist!! After a few years they begin to accept Darwin's idea because (unlike modern creationists) many of them, especially younger scientists, had respect for the evidence--evidence that Darwin piled high in his "Origin of Species," evidence that continued to grow as new geologic data came in. The battle over the schools, which were originally creationist, only came AFTER evolution was generally accepted due to overwhelming evidence. Your sorry portrait of the scientific community as a dishonest, scheming lot does you no credit. I am shocked!
[[If someone comes along to show that their papers are based on nonsense, they might lose their reputation and jobs.
That is why they are mostly not really scientists that care for the truth but care for themselves first.(human trait)
There are good scientists but most of them fear ridicule and persecution from the establishment, and one cannot blame them if they just ignore the subject entirely. It is a career breaker not a maker for sure.]]
10,000 scientific papers all based on hidden nonsense??
I am glad that I am here so that I can deny this MONSTROUS LIE. (For you, a delusion since you may actually believe in it.) Having known a few important scientists to varying degrees, and having read the books of others, it is very clear to me that the vast majority of scientists go into science because they want to explore the unknown. They are very much interested in the truth! Oh, sure, there are a few dishonest scientists who are industry shills or who "enhance" their papers to make themselves look good. A few fudge data because they think they will be vindicated when more scientists follow up their research. What of it? There's crud at the bottom of every barrel.
A favorite sport in the scientific community is to find errors in another scientist's paper. Moreover, that paper must be accepted by a journal before it can be published there. Journal reputation is not enhanced by printing crap! Nobel prizes aren't given out for hiding behind accepted doctrines! Science is a self-cleaning operation.
[[It is up to the people who care about the truth to be scientific and challenge the dogmatic views with intelligent questions so there could be progress.]]
I take it that you see yourself as one of those people. But isn't it also your duty to know something about the subject that you criticize it? Even if you don't believe in the arguments you should know them--backward and forward! I studied creationist books when I criticized creationism. I studied the Bible (and many other sources) when I criticized Bible-believers. So, you have another reason to study those books that I have recommended, every one of them.
[[That does not mean I would not try and get those books but it would be for my own research not to try and check if your claims are supported.]]
That's the best reason, the main reason I had in mind. However, you should also be willing (as a searcher for truth) to actively search out material that might prove yourself wrong, especially key books like the one Dr. Prothero wrote. Book references, of course, cannot be used as substitutes for arguments. On that we both agree. Every time a creationist gets stuck he tells me to go read this or that book and that the answers will be in there somewhere! That won't do! But, if a book is referenced for its data rather than as a substitute for reasoning, then that is a good reference.
THE FOSSIL RECORD **********************
[[If there should be a gradual change like Darwin proposed, why doesn't it appear in the fossil record?]
"It most certainly does appear in some cases!"
(1) Burden of proof.]]
(Lewin, 1981, p.645, Nature)
This may be the first detailed fossil documentation going from one species to another. It involves mollusk fossils collected near Lake Turkana in northern Kenya. A fairly long stasis was interrupted twice by brief, abrupt periods of evolution covering perhaps 5000-50,000 years, and the transitional fossils nicely connect the old species with the new ones. Those two periods of stasis interruption correlate with a dramatic drop in lake level.
(P. D. Gingerich, 1982, Time Resolution in Mammalian Evolution; Sampling, Lineages, and Faunal Turnover. Proceedings, Third North American Paleontology Convention, Montreal, vol. 1, p.209)
Professor Gingerich of the University of Michigan found fossil teeth of early primates living in Wyoming U.S.A. that graded smoothly between two species with different teeth.
Dr. Prothero actually supplies photos (p.180) of smooth transitions of 1) Praemurica (over about 4 million years); 2) Globoconella (from unkeeled forms to keeled forms over about 2 million years); 3) the genus Fohsella (from unkeeled ancestral forms to a highly keeled species). These are planktonic foraminifera.
"An intensive study of 15,000 trilobite fossils from Wales provided a good example of what happens when a scientist looks instead for the in-between species. The trilobites, a massively successful group of arthropods that flourished through the Permian, showed so many intermediate forms that classifying individual fossils into species became an exercise in arbitrariness." (Tobin and Dusheck, Asking About Life, 2nd edition, p.386)
Thus, we have an example from a standard college biology textbook.
[["Why then is not every geological formation and every stratum full of such intermediate links? Geology assuredly does not reveal any such finely graduated organic chain; and this, perhaps is the most obvious and gravest objection which can be urged against my theory."
Charles Robert Darwin,
The Origin of Species: The Preservation of Favored Races in the Struggle for Life, 1st edition reprint.]]
[[“The extreme rarity of transitional forms in the fossil record persists as the trade secret of paleontology (study of fossils). In any local area, a species does not arise gradually by the steady transformation of its ancestors, it appears all at once and fully formed."
Dr. Stephen J. Gould, Prof of Geology and Paleontology, Harvard University. Mentioned in one of his regular columns in Natural History Magazine (1977) and also in The Panda's Thumb, 1980, p. 181-182]] {Thank you for an accurate and well documented quote!}
The key word in this last quote is "rarity." This quote stands as testimony to the fact that there are transitional forms in some cases.
This statistical pattern is what led Stephen Jay Gould and Niles Eldredge to develop their theory of punctuated equilibrium. Thus, the statistical pattern of gaps at the genus or species level--and the no-gap exceptions which do exist--are fully explained. There is no threat here to macroevolution. By the way, I hope that you actually read The Panda's Thumb. It is a fun and insightful book. I might add that at the higher levels (fish-amphibian, amphibian-reptile, reptile-mammal) the fossils grade so smoothly that placing the boundary is somewhat arbitrary. Isn't that what macroevolution predicts? Macroevolution (with punctuated equilibrium) also accounts for statistical gaps at the genus and species level.
[[Missing links are not what you think you are, I have explained them and you did not address my explanation at all, and instead you just insist that my "definition of a missing link is not the point."
"We are concerned with a paleontologist's understanding of a missing link."
Again an argument of authority fallacy.]]
Am I to accept your ideas about missing links, even though you are not an expert, and reject ideas from real experts because they are "authority figures?" If you want to know about strange noises from your car you consult a mechanic; if you want to know the details about "gaps" or "missing links" in the fossil record you consult a paleontologist.
[[The truth is that both the Prokaryotes and Eukaryotes just appear in the fossil record with no transitions in between.
Your explanation is not supported by evidence. it is a nice idea if the fossil record shows what you are claiming, since it doesn't, throw it in the bin already and start looking for an actual explanation that fits the facts.]]
Do they? Since the boundary between prokaryotes and eukaryotes in the geologic record is not clear, how can you say there are no transitional forms? Don't you have to search at the boundary and hope that the record there is complete? At most, you can only say that we haven't found any. (The search is very difficult.) By the way, the fossil record is not the only source of information relating to the transition between prokaryotes and eukaryotes. Have a look at Dr. Donald Prothero's book, "Evolution: What the Fossils Say and Why It Matters" (pp.154-157), for powerful evidence of that transition.
[["Conditions are rarely so good and consistent as to preserved a long series of gradual changes in the fossil record, especially for larger animals."
True, but a specie needs to be successful for enough time to adapt and evolve to an environment, and with enough time, it is bound to leave a fossil eventually like it happens.]]
Did you know that at one time a great flock of passenger pigeons could blackened the sky in America for 3 days as it flew by? How many fossils do you think they would have left over thousands of years? I think paleontologists know of two! Bats make up nearly one quarter of all mammals. How many bat fossils do you think we have? Look it up! Success doesn't necessarily mean lots of fossils, especially in areas where they are rarely preserved. Fossil preservation is a rare and chancy affair on land, so you can't expect a nice, tight series of fossils covering many millions of years. There is also the matter of erosion. The longer the time span, the more likely an area will be eroded. On land erosion is the rule. There is also the matter of migration.
THE HOMINID LINE FROM THE EXTINCT APES TO US ********
[["As I mentioned earlier, over the years quite a few hominid fossils have been found and they all get reported in various scientific journals. Please read Dr. Prothero's book and decide whether the evidence is still near zero"
I asked for scientific papers and the evidence they present.
I do not want to go and read an entire book to find the evidence you think it contains.]]
You need only read the 16 pages that constitute chapter 15. (You really need to read the whole book as it is one, beautiful summary of the transitional fossil evidence for animals in general. If short on time, you could just look at a couple of chapters to get a feel for the massive evidence. It's not a boring book.)
Surely, you are not of the opinion that the hominid species listed a little further down in this post never showed up in any of the scientific journals! Am I supposed to spend hours of my time searching for research papers to prove that such fossils exist? Why would I waste time demonstrating the obvious? Have you ever heard of a new species not being discussed in a scientific journal? My point is that the fossil evidence for hominids does exist contrary to your claim. If you want the details for each find you will have to do your own research, or you can read a few pages in Dr. Prothero's book. If you want to claim that the paleontologists who set up the hominid (now hominin) taxon, who assigned fossils to it, got it all wrong then you will have to do more than make bold proclamations, especially since you are not an exert in classifying fossils. (If you have spent years handling these ancient skulls let us know and I'll retract this last statement.)
[["All {of the hominids} are extinct now except for one member of that family--us.)"
That is an assumption, since we have, not found any yet, and since 1/3 of the deep wooded areas of the planet was never foot surveyed once, it is a pretty bold assumption.]]
Not true! When Darwin wrote "The Descent of Man" in 1871 one could honestly say that there were no good hominid fossils. Since then thousands of hominid {now hominin} fossils have been found, "…including a few good skeletons and many good skulls that show clearly how humans have evolved over 7 million years." "A tour through the bomb-proof hominid vault in the Kenya National Museum in Nairobi is a revelation: a whole room full of fossils that document our evolution, and whose existence the creationists {and others!} must deny." (Dr. Prothero, from "Evolution: What the Fossils Say and Why It Matters") Museums in Africa, Europe, and Asia have large collections of our early ancestors. Books and exhibits allow the public to see these fossils up close.
Hominids can only survive as viable populations, meaning that they would have to travel some distance to successfully hunt and gather. Most likely the whole population would be moving about to follow resources. You can't hide them under a leaf! Moreover, when a population dips below a certain level, calculations show that they go extinct. Forget about Adam and Eve hiding out in some jungle version of a bomb shelter. That the other hominids are extinct is a sound conclusion made by people who are better informed on these matters than yourself, but I'm not going to debate it since it is irrelevant. The real point is that we do have good intermediates between the extinct apes and Homo sapiens. Let me list some of the fossils making up our own family tree, the Hominidae. (A more recent revision throws in Chimpanzees, Gorillas, and some other apes, but we will use the older definition throughout my posts.) In his book Dr. Prothero comments on each fossil species, a good reason for you to read his book.
Dated at about 6-7 million years ago is Sahelanthropus tchadensis, the earliest entry in our own taxonomic family (Hominidae). Other fossils (mostly going from older to younger) are: Ororrin tugenensis, Ardipithecus ramidus, Ardipithecus kadabba, Australopithecus anamensis, Australopithecus afarensis, Australopithecus garhi, Australopithecus bahrelghazali, Australopithecus africanus, Paranthropus aethiopicus, Paranthropus boisei, and Paranthropus robustus. In our own taxonomic genus we have: Homo rudolfensis, Homo ergaster, Homo erectus, Homo cepranesis, Homo mauritanicus, Homo heidelbergensis, and others. Although some adjustments may have been made since Dr. Prothero wrote his book in 2007, the evidence is going to be more--not less. It clearly refutes your odd claim that no hominid fossils have yet been found!
[[Their Micro-evolution also shows up in the fossil record, it is their Macro evolution(going to humans) that is completely missing.
Thus the evidence is simply not there.]]
Check out the above list of hominids. (I bet a few new ones have been added since the above taxonomic family was sketched out!) The hominids (now hominins) ARE the evolutionary line leading from extinct apes to us! Once again you are using "microevolution" in a confusing manner. The diversity of apes in the Miocene is a case of macroevolution as is the rise of the hominids. (See my previous posts defining micro and macro evolution.)
[["The older hominid fossils show a distinct mix of human and ape characteristics."
Where? What characteristics?]]
I shall refer you to Dr. Prothero's book "Evolution: What the Fossils Say and Why It Matters," chapter 15. Once again, this is a referral to data--not a substitute for reasoning. On pages 349-341 Dr. Prothero mentions some of the mix of human and ape characteristics that have been found. (If those fossils had only ape characteristics they would not be classified as hominids {that would be "hominins" in the recent taxonomic revision}; If they had only human characteristics they could hardly be placed anywhere near the front of the hominid line in older strata. Obviously, many of those species have a mix of human and ape characteristics unless you are challenging the whole taxonomic foundation! In that case I'd like to see your credentials or, at least, your sources.)
[["Did you know that some human populations have a significant number of Neanderthal genes?"
Yes, so what?
Showing that Neanderthals are somehow related to us, does not show that we macro-evolved from their ancestor, or that they macro-evolved from an ancestor at all.
It just shows that we and Neanderthals are compatible enough that somewhere along the line in history a Neanderthal could have mated with a human and their genes appear in some humans.
Extrapolating that, to support the idea that we share a common ancestor is pushing it.]]
When Dr. Prothero wrote his excellent book Neanderthals were classified as a different species (Homo neanderthalensis). More recent evaluations lean towards a subspecies (Homo sapiens neanderthalensis). Our two lines of ancestors are calculated to have diverged around 600,000 years ago. DNA studies suggest that two or three interbreeding events occurred, the last one being perhaps 50,000 - 60,000 years ago.
Common ancestry is the reason why groups of animals or plants share certain similarities. We are not talking about similarities that are environmentally necessary, such as the ability of certain plants to store water in a desert, or the form needed for fish to swim really fast in the ocean. We are talking about non-essential similarities that only make sense if inherited from a common ancestor. For example, rats, bats, elephants, horses, and whales all share mammalian characteristics despite the radically different roles they play. Unless you believe in really freaky odds you have only one place to go to explain such shared characteristics--inheritance. The whole mammalian line evolved from a common ancestor! As mammals diverged, those characteristics more or less went along with them.
The reason the Neanderthals are so similar to us in non-essential details (so similar that interbreeding was also possible) is that we share a recent ancestor. Thus, we have taken our first step back on the hominid line to the extinct apes!
[["... Ape ancestors came in a variety of sizes and many of them, no doubt, were hunted. "
Straw-man?
I though we were mature enough to understand that we were talking about the human sized apes here, since we were talking about human origins.]]
Much of your material, sorry to say, is nebulous and poorly connected, and I can only guess at your argument. Perhaps you are not aware that most of the hominids are considerably smaller than modern humans. We're not talking about a line of giant apes who can fend off all attacks! And even hominids the size of us would be easy prey for large cats. "Lucy" was three-and-a-half feet tall and had a mixture of ape and human features such as long dangling arms from apes, and spine, foot and leg bones that enabled her to walk upright.
THE NATURE OF BIOLOGICAL EVOLUTION
[["but {Darwin's contribution of} natural selection is still the main engine."
True, but you cannot call natural selection if you don't explain the natural selection part can you?
What natural habitat selected a particular specie?]]
The "natural" in natural selection refers to nature (the environment) as doing the selecting. It is not a statement about a particular environment. Compare that to artificial selection where humans make the selections (as in breeding). The handful of principles that make natural selection work (and artificial selection too) are not difficult to understand and may be found in any good, general biology textbook. None of these principles requires identifying a particular environment.
Environments, of course, are very important in the actual evolutionary process. Deserts, for example, favor plants with thick bodies (protected by spines) for storing water, or plants with very deep roots to tap into underground water, or delicate plants that quickly flower after a rain, set seed, and die. Their seeds survive until the next good rainy season arrives and begin the cycle again. There are many strategies that plants and animals can adopt for the various environments, and the study of such is an important part of evolution. But, there is no requirement to identify environments involved in order to demonstrate evolution. Enough fossil evidence or genetic evidence will do.
[["Natural selection applies to human evolution as well,"
Nope it does not, they claim it does, yes.
What natural habitat selected humans out of the other apes?]]
The principles behind natural selection, the main engine for evolution, make no distinction between humans and other animals or plants. If the required conditions are present, and they are, then evolution is happening (though periods of stasis are possible). You still see a false need to identify environments. If the evidence is in the fossil record or in the DNA that is enough to say that evolution has gone from "A" to "B." Knowledge of the environmental driving forces are not needed to establish the fact of an evolutionary sequence.
[[Macro as you said is a label for a postulation(extension) of evolution(micro-evolution).
"Those words describe how much evolution has occurred, not how it has occurred. They are not important scientific terms, only terms of convenience."
Nope, Evolution theory DOES NOT describe how much evolution has occurred but IF it does occur. …]]
I really don't understand what you are talking about in your discussion of these terms, so let me go over macro and micro evolution once again. Darwinian evolution, later morphing with genetics to become Neo-Darwinian evolution, or just modern biological evolution, is the general explanation of the diversity of all life on earth. Among other things, it asserts that any two species has a common ancestor, that they are all related in a "family tree." That's what scientists mean when they talk about "evolution." (The evidence from the fossil record, from DNA, from comparative anatomy (cladistics), from cytochrome c and certain other large molecules, from the geographical distribution of species, from vestigial organs, from atavisms (genetic throwbacks) and from a range of other evidences, prove evolution beyond a reasonable doubt. That's why you never see any debate about the fact of evolution in scientific journals. That's why university textbooks all over the world treat it as a fact to be taught and explained. The scientific debate ended a long time ago! I've talked about some of this evidence elsewhere, but I'm not going to write a whole textbook in this forum to recap the massive evidence generated by 100 years of biology! Nor, mostly, will I spend time documenting facts that have been accepted throughout the scientific world for years. It's all out there if you want to study it.)
Darwin thought that evolution constantly moved along on little steps that led, eventually, to the diversity of all life, and that was the view for some time. Neo-Darwinian evolution (Darwinian evolution + genetics) is one idea as to how evolution proceeds; don't confuse it with microevolution. Neo-Darwinian evolution may refer to evolution within the species level (in which case we are talking about microevolution) or it may refer to evolution above the species level (in which case we are talking about macroevolution).
A more recent view of evolution, punctuated equilibrium, was put forward by Stephen Jay Gould and Niles Eldredge to explain statistical gaps at the species and genera level. Species mostly remain in stasis (very low evolutionary activity that is mostly random) but go into overdrive when conditions are right. It can also be referring to microevolution or macroevolution.
The big point is this: Neo-Darwinian evolution can refer to microevolution OR macroevolution as can evolution incorporating punctuated equilibrium. Natural selection, Darwin's main idea, is the main engine for both.
[[First of all there ISN'T even a single fossil that could NOT be explained by something else, rather than a transitional fossil of macro-evolution.]]
Why don't you give us a detailed example to illustrate your point? I pointed out in some detail in a previous post that the fossil record, DNA, cytochrome-C, and comparative anatomy all yield similar evolutionary "trees." Inherited change through time is the only rational explanation. With the general pattern at hand, we may surmise that every fossil is part of the evolutionary "tree" and, therefore, they are all connected by evolutionary pathways. That makes all of them intermediate to what came before and after along that branch of evolution. If you have a better explanation for this fantastic convergence of data I'd love to hear it. The evolutionary "tree" is the primary prediction of macroevolution! It is verified by the completely different methodologies listed above.
[[Second, even if you find the transitional fossil, not knowing HOW this transition occurs or WHY, means only that MYSTERIOUSLY a specie similar enough to look like a transition, appears in the fossil record.]]
If two fossil species look very much alike that means (almost certainly) that they are closely related and, therefore, if one fossil is slight older than another that constitutes prime evidence for a transition fossil.
The evolutionary "tree" relationship for life makes it clear that life has evolved, and this macroevolution is reflected in the fossil record. Fossil similarity correlates with similar geologic times and locations. Isn't that what macroevolution predicts? If it's in the right place at the right time, and if it links fossils above and below its geologic level in a particular locality, that's strong evidence for a transitional fossil. If that fossil is part of a sequence of fossil changes that can be traced further upward or downward in the fossil record, then we have even more evidence. We are not flying blind! Understanding why the transition took place, be it chance events, continuous environmental pressure over time, or a change in environment, would be nice but is hardly necessary.
[[Fist of all there is no evidence that apes did not walk upright from start.]]
Are you an expert on ape mobility? If not, then you should cite a textbook or other generally accepted authority. A dividing line between hominids (in the original sense of the word) and their ape relatives is the ability to walk upright. Probably any ape could walk a short distance on two legs; walking more or less upright naturally is another matter. It's all in the bones and their connections. Such details tell us whether walking was upright or not. Many, perhaps all, of the extinct apes went primarily on all fours.
[["If a small group of plants or animals evolves for a long time, through many stages, and then becomes very successful and large, the fossil record will usually show fossils from the originally successful population followed by the later successful population."
We agree, the most successful are more likely to leave fossils then the less successful ones.
(1)But again this only means that you are failing the burden of proof for your claim and putting an excuse for it.
You cannot do that when trying to support a claim with evidence.]]
This is a theoretical model (part of the generally accepted punctuated equilibrium model) that explains the fossil gap pattern, a model that relies on the fact that there are small, fringe populations as a rule. That's why it begins with an "if." Nobody is claiming that it explains every gap, but it is a strong enough reason to explain most gaps. Surely, you are not claiming that small, rapidly evolving populations cannot, on occasion, become highly successful.
[["The in-between fossils, belonging to small populations in small areas, will usually not be found."
true but, you are assuming many things here, you are assuming that this applies to every situation the fossils are missing, which is not the case. In fact this excuse only holds if there is evidence to suggest that a specie is "belonging to small populations in small areas". Failure to show that, it means that punctuated equilibrium does not account for those.]]
There is no excuse here. It is a simple and logical statement and it is not intended to explain every gap. If you have this kind of situation you don't expect (as a rule) to find their fossils. Therefore, if there is a breakthrough in one of these populations, the transitional form will not likely be preserved. Simple logic. Small populations in outlying areas where the environment begins to differ, where mutations and genes have their greatest effect on the population, is exactly where you would expect accelerated evolution. If the main population covers a large region, the outlying populations along its perimeter will likely represent a variety of environments. These outposts are potential hotbeds of evolution compared to most other areas.
[[Apart from that minor problem, punctuated equilibrium also has the problem of containment which you failed to address yet.
Apart from fishes in ponds how does a specie get a totally new environment and "is belonging to small populations in small areas"?
The "WHY" of the hypothesis is completely ignored thus not even reaching the level of a scientific Hypothesis for macro-evolution using punctuated equilibrium.]]
Containment problem?? I have no idea of what you are talking about. How do fish in a pond fit in? I'd love to find out! Please use more space in presenting your ideas and not be so cryptic.
May I ask what kind of background you have that allows you to speak so authoritatively about punctuated equilibrium? You know nothing about the subject (as far as I can tell) but have no trouble concluding (as best as I can make out) that an important feature of it doesn't rise to an hypothesis! Since when did you become the expert? I seldom see any sources, let along good ones. It's always proclamations based on some idea you have. Honestly, most of your questions and arguments show no awareness of the subject! I really don't have the time to be your tutor in such matters, but I'll carry you a few more miles.
You really need to take a few months off and study a good, solid college-level textbook on biology such as Asking About Life, 3nd ed., Tobin and Dusheck. It is a fascinating book--not a choir. Seriously, consider reading Dr. Prothero's book. If nothing else read Undeniable: Evolution and the Science of Creation by Bill Nye. That's the easiest one to read but it will correct many misconceptions. Bill is an excellent teacher.
As the main population grows its borders eventually push into new terrain that is not so favorable (the new environment), and populations tend to either die out or adapt to these new environments. As this goes on and on there is a tendency for outlying populations to be cut off. A river changes, they get too far away, a new predator takes up residence between an outlying population and the main population, a mountain chain arises, a canyon erodes, or a hundred other causes may lead to permanent separation. At that point, the outlying population continues adapting to its new environment and might, over time, become a new species. Outlying populations tend to be small because they represent only a portion of the perimeter of the main population and often adapt to limited niches.
[[The Cambrian explosion is a problem because there is not enough time for the standard Darwinian evolution to happen and generate such an explosion of new species through adaptation of the previous species recorded in the fossil record.]]
Are you going to refer us to a scientific paper or a textbook or is this another of your proclamations? The Cambrian "explosion" took place over 10-30 millions years depending on where you measure it. Given that life was moving into a totally new niches without any competition (where evolution would be accelerated), that seems like plenty of time to me.
[["By the way, the Cambrian "explosion" probably took 10 to 30 million years. It didn't happen overnight! "
It did happen Overnight in evolutionary terms. I thought we were having a mature debate and you would understand that statement since it is often used in the scientific community to mean just that.]]
I understand how the phrase is used. Who are you to declare that 30 or even 10 million years is not enough? Once again I see only a proclamation from a fellow who has no expertise in paleontology.
[["Just prior to that time the Earth seems to have been frozen over, and one idea is that it thawed to a degree that allowed life to take off"
Lol, yea nice explanation, soon we will hear that the earth burned to a degree that it allowed life to take off.
These are not even scientists, the drunk around the corner could come up with at least an explanation rather then a dodge.]]
If it seems silly to you it is because you are terribly ignorant of geology. However, that doesn't prevent you in the least from pontificating on the subject and ridiculing others, does it? Shame! Those who know the fewest facts are least likely to be embarrassed by the truth! I'm sorry, but I'm going to have to embarrass you.
"The evidence: Neoproterozoic rocks on all of Earth's landmasses (except Antarctica) show glacial striations produced by huge ice sheets. We also find tillites, dropstones (chunks of rock released from melting icebergs), and varved clays from glacial lakes. The episode of frigid conditions has been named the Varangian glaciation …" (Harold Levin, The Earth Through Time, 8th ed., p.251)
I suppose I should also tell you that the Neoproterozoic occurred just prior to the Cambrian. Some scientists think the whole Earth was mostly a giant snowball!
[[It is basic knowledge that if everybody marries his sister/brother, mutation rates are higher.]]
You are confusing the rate of expression of a mutation with mutation rates. Two different things! If two recessive, matching mutated genes are received by a baby, the odds being much greater for inbreeding, then the mutation is expressed. Mutation rates refer to how often a site on the DNA is changed by radiation, chemicals, or whatnot.
[["Of course positive mutations occur!"
(1)Evidence?]]
J. Lederberg and E. M. Lederberg, J. Bacteriol. 63:399 (1952)
These researchers demonstrated way back in 1952 that a mutation can arise that allowed the species of bacteria they were growing to survive the antibiotic streptomycin. Patricia Clarke identified mutations of Pseudomonus that enabled them to grow by metabolizing novel organic chemicals. Francisco Ayala found that the size of a dense populations of fruit flies increased as genetic changes occurred that enabled the flies to use their food more efficiently. (F. J. Ayala, Science 162:1453 (1968)) Paul Hansche found a mutation in yeast that doubled the gene that codes for the enzyme acid monophosphatase. The mutant yeast, with an increased amount of the enzyme coming from the extra gene, could obtain more organic phosphate from its environment which gave it an advantage over the non-mutant yeast. (P. E. Hansche, Genetics 79:661 (1975))
If you trouble yourself to google "beneficial mutations" you can find scores of positive mutations! Why do you ask me to provide sources when they are readily available? Ask for a source if the material is difficult to find.
[[Basically how does punctuated equilibrium explain the gap in the fossil record compared to the extinction of older and more adapted to the usual environment?(I know that not all the older versions go extinct but some do and punctuated equilibrium makes a contradiction when this happens)]]
Please expand this statement so that I can understand what you are talking about. Gap? Punctuated equilibrium explains a certain class of statistical gaps not "the gap."
[["Today, Punctuated Equilibrium is widely accepted among biologists and paleontologist because it explains so many facts. To better appreciate it you need to study a good site on the Internet."
Lol man seriously, I pointed to you contradictions in Punctuated Equilibrium that do not explain the facts which you ignored.]]
These "contradictions" only exist in you mind because they apply to a faulty conception you have of punctuated equilibrium. (That's my best understanding based on what I can make of your argument.) I can either choose your analysis (that of an amateur) or I can choose the analysis of the majority of the world's experts on the subject.
[[NATURE SELECTS the ones who will survive in a particular environment.
(the ones that remain in the old environment should survive though, assuming the old environment still exists)]]
Exactly! You have that exactly right. Sooner or later, usually sooner, environments change. Jungle may become grassland, ice-covered land may become jungle, new predators and diseases might evolve, grasslands may turn into deserts, an asteroid might collide with the Earth, etc. The fossil record indicates that most species only survive a few million years.
[["The shape of the adult human face is that of an immature chimp's. "
LOL this was awesome.
Did you know that; that cannot happen for the simple fact that chimps have so many different things.]]
[[-Huge chin, sticking out of the face where humans don't.]]
I said "immature chimp's" (as in very young). There is a huge difference you know! I get it. You grabbed a photo of an adult chimp and just assumed that an immature chimp was a smaller version. Tisk! Tisk! By now you should have realized that I don't make really stupid statements, so there must have been more to it. Right?
[[-So yes, you would be right if you give that poor human a hell of a beating in the face to completely restructure the bone of his skull, then you might not distinguish him from an "immature chimp" when he is still an embryo lol.]]
What seems obvious to a man who knows 10 things might be rejected altogether by a man who knows 1000 things. Give your reply some thought. You don't want to make a complete fool out of yourself! Hint: Read the last pages of chapter 15 in Dr. Prothero's book. That will tell you what it's all about (with drawings).
PROOF AND CRITICISMS OF MACROEVOLUTION ************************
[[(1)NO, the burden of proof is on you to support your claim that macro-evolution(label) is supported by evidence.
", evidence that is absolutely decisive."
Please deliver the very best you have.
I am still waiting.]]
Did you miss my discussions on the evolutionary "tree?" There's the proof (decisive evidence) for macroevolution in a nutshell! Such an amazing convergence of data from three or four totally independent sources, all pointing to similar evolutionary "trees" has no rational explanation other than macroevolution. (I'm using "macroevolution" in its normal sense, the evolution of plants and animals above the species level. The diversity of mammals would be a case of macroevolution.)
Keep in mind that this is a forum! I can give you a broad overview of the decisive evidence for macroevolution, answer some specific questions, demonstrate its power by asking other questions, correct erroneous concepts, and defend evolution (macroevolution) against your specific objections, but I'm not going to write a textbook for you! I'm not going to dig up endless references for common, scientific knowledge that was established many decades ago. Even if I had the time, I would not waste it duplicating any of the excellent books already in print. If you want to see a book-sized explanation that goes into endless detail, that gives lots of references, I can recommend books for you to read, books that are not so simple (or so far advanced) as to waste your time. If you have less time, then study some of those excellent Internet sites you mentioned instead of searching them for quotes! (http://evolution.berkeley.edu and http://www.talkorigins.org)
If not macroevolution, then how do you account for the order of the fossil record? How is it that this order reflects the evolutionary "tree" relationship? How is it that we can trace the horses back to small, shrub-eating, forest animals with real toes? And, we haven't even looked at other strong lines of evidence for macroevolution. (The distribution of plants and animals reflect macroevolution. Vestigial organs reflect macroevolution. Groups of plants and animals that share a set of non-essential characteristics--indicating a common ancestor--clearly reflect macroevolution. I hardly have the time to explore all these other proofs in depth so I'm mainly listing them for your own interest.)
Since you intelligently reject religious mythology, and since you reject macroevolution, I am left wondering how you account for the origin of humanity? Where, in your opinion, did Homo sapiens come from?
[["Dr. Prothero describes the case for the giraffe nicely. In the giraffe the laryngeal nerve is an incredibly clumsy "design" that actually can endanger the giraffe to some extent."
…The "laryngeal nerve is clumsy" because we do not know yet why it is like that, we think it is clumsy if we assume macro evolution caused a clumsy evolution, like the appendix in humans (not working).
This is not evidence of macro-evolution, but only a possible explanation of such occurrences assuming macro-evolution.
NOT THE ONLY POSSIBLE EXPLANATION.]]
[[An easier expansion is that they serve a function we have not yet discovered like what usually happens.]]
The laryngeal nerve is like a wire that connects two regions so that messages can be sent. The fine details of transmitting messages or of the construction of that "wire" might leave room for future discovery, but its overall function is simplicity itself--it's just a "wire." In the giraffe it is vastly longer (looping awkwardly about) than is required. One doesn't need a PhD to see that such an arrangement is incredibly clumsy. There is no mystery about that!
The point of my example is that we do know--BEYOND A REASONABLE DOUBT--why that situation arose. Macroevolution accounts NATURALLY for it and is not just a "possible" explanation! There are no credible alternative explanations known. If you would only read Dr. Prothero's book you would get a better feel for such things. Remember, the possible is no substitute for the probable. It won't do to say that there might be other "possible" explanations when a good one is at hand with no serious alternatives in sight.
[["(Evolution can sometimes recycle a vestigial organ for another purpose.)"
LOL
Wanna see you supporting that claim.
"another purpose" Like what?
You know how ridiculous that claim is?
or you believe everything they claim because they say it?]]
Darwin, himself, understood that evolution could modify an existing structure into one serving an entirely different purpose. Now isn't a vestigial organ an existing structure, one that no longer serves its original purpose? The wings of penguins, once used for flight, now serve as flippers. Obviously, the flight capability of a penguin's wings had to become vestigial before evolution could completely modify them as flippers. If they were still needed for flight the transition would have been fatal. "Wasps and bees did not develop a sting de novo in order to protect themselves. They use a modified egg-laying tool that is adapted in their more primitive relatives to insert eggs into plants. The result is that only female wasps and bees can sting, and the males are defenseless." Douglas J. Futuyma "Science on Trial." Professor Futuyma's book received high praise from Ernst Mayr.
The only reason I made this comment is because creationists often claim that vestigial organs might have unknown uses and, therefore, are not really vestigial organs. However, there is no reason why evolution can't modify some vestigial organs, to some degree, somewhere, at some time, for a totally new purpose. Simple logic. The laugh is on you.
[["If an animal has a vestigial organ that only makes sense in a wholly different animal, then that is prime evidence of macroevolution."
What?
It only shows that the animal is a wholly different animal.]]
It's a fact that vestigial hind legs exist in some whales, actually protruding from the sides in rare cases! Yes, I completely agree with you that the whale is a wholly different animal than its four-legged ancestors that hung around rivers! I would say that evolving from 4-legged animals to whales qualifies as an excellent example of macroevolution. Where else did those whales inherit their leg genes?
[["Indeed, whale fossils trace back to a four-legged river animal"
I could come up with 100's of other possibilities for "vestigial remnants of hind legs" on whales.]]
We still have the question as to how the whale got its leg genes, degenerate though they now may be. Why don't you dip into your 100's of other explanations and see if you can give us 4 good ones? While you are at it you might explain why human embryos go through a stage where they have a fur coat, and why chickens have remnant genes for teeth which can be activated in the laboratory. These are genetic clues to the nature of past ancestors who were very different! It's more evidence for macroevolution!
Why do humans have a remnant of a tail which, in some individuals, is actually expressed as a degenerate tail? Where did some snakes get the genes for their vestigial hind legs? Why do snakes have one lung defunct and one lung good? Snakes were probably a lizard-like animal when both lungs were fully functional, when they had functioning legs. Macroevolution! How do you deal with this fact: "The routing of nerves and fluid pathways in the human body resembles the tangle of wiring and pipes in an aging house, a heritage from fish and amphibian ancestors." (Neil H. Shubin, "Scientific American" January 2009, "This Old Body"). Macroevolution once again!
[[Can a whale have legs/flippers without we imposing our explanation that it must have been a land animal before?
This is bias.
This is no evidence at all.]]
You are hardly an expert on whale anatomy, so your opinion here is worthless. What on earth would an ocean-going whale be doing with a pair of hind legs? Vestigial legs on whales are not always expressed, so they obviously serve no hidden function. The only good explanation is that they are genetic baggage left over from their days as river animals.
[[They could have served a purpose before some catastrophic events that shaped the entire planet and then micro-evolution could have made them inert or extinct, while others without "vestigial remnants of hind legs"(flippers) survived.]]
A former purpose? You mean like whales dancing on their legs? This wild and woolly speculation about whales on legs and an undocumented catastrophe does you no credit! These days we also have a decent fossil record that traces whales right back to a four-legged river animal. Again, see Dr. Prothero's book for a rundown of the evidence.
[["This is the primary prediction of macroevolution! {the evolutionary "tree" relationship}"
NO NO NO NO
This only shows Micro-evolution, it should not predict that some branch will eventually completely change.]]
You're confusing the prediction of a "tree" relationship (a general concept) with a prediction as to where macroevolution will eventually lead. The latter cannot be predicted as you noted. That we will get a "tree" relationship IS the primary prediction of macroevolution. Macroevolution predicts that any two species will have a common ancestor, and that means a "tree" diagram. The main prediction of macroevolution has been verified by several independent methods as mentioned elsewhere in these posts.
[["Man seriously you need to study the subject more because you are taking assumptions that have been hammered in your head as facts and you are not making any sens.
There is no link between "primitive cells"(like prokaryotes) and basically any other specie/bacteria on earth.
There is to this day no explanation supported by evidence for their macro-evolution.]]
Prokaryotes ARE bacteria! Modern DNA studies show that the common ancestor of prokaryotes diverged into at least 2 of the biggest branches of the evolutionary tree (the domains of Eubacteria and Archaea). That we all share the same DNA code is clear evidence that we are linked by macroevolution. Why else would we have the same code?
[[Why did they {prokaryotes} change when for millions of years they remains virtually the same?]]
Their unchallenged reign was closer to 2 billion years! What's your point?
[[Infact some scientist would admit that at least one of the prokaryotes could have come from a meteorite, since 2 different types of prokaryotic bacteria appear on earth virtually at the same time and that contradicts how Abiogenesis or evolution should happen.]]
Your understanding of abiogenesis and evolution leaves much to be desired! Why shouldn't Eubacteria and Archaea (both domains consisting of prokaryotes) share the earth at the same time? Any prokaryote arriving from outer space (and another world) would not have the same DNA code assuming they even had DNA. Moreover, if prokaryotes from space initially seeded earth, and that all of us consequently shared their DNA code, that would hardly be an argument against macroevolution!
[["(Life might have begun with a number of different cells in different locations, but one line survived and all life today bears its stamp.)"
Seriously you did not even explain anything in that statement.
I bet the book of Mormon gave a better explanation than you did.(never even read it)
What stamp? seriously just take the prokaryotes and try to imagine how the hell did the cell nucleus come from the prokaryotes by a natural environment?]]
[[… you are claiming that somehow, after millions of years, Prokaryotes become Eukaryotes naturally(miraculously).
No cell nucleus went to very complex cell nucleus just like that, nature can do everything.
No explanation needed, just believe it.]]
You need to learn something about the subject before you start telling everyone what can or can't happen! I was talking about the common DNA code for all life. That is prime evidence that all life traces back to one source. You will understand it much better if you take the trouble to study a college level introductory textbook in biology. "Asking About Life" by Tobin and Dusheck is an excellent (and fun) textbook. I have studied it myself.
Studying Tobin and Dusheck's textbook might actually be fun for you (even though it's about 900 pages long) and you will be able to understand a lot of things, including how prokaryotes may have gotten their nuclei. Or, you can just look up the latest findings on Wikipedia where you will be given 4 reasonable explanations--there being no final conclusion as of yet.
The fact that you can't imagine how it could have happen is of no importance. You don't have the background to understand how things work in that situation. Creationists make this mistake all the time when they claim that evolution can not explain this or that. It might seem impossible to their minds, but so what? Scientists, because of their extensive knowledge of the subject, can see much deeper into the matter of the origin of the nucleus, and they have found several reasonable explanations.
[["DNA has proven that were are all descendants from the same single cell."
Nope it did not, where is this proof?]
You still did not give me any proof but just a very bold claim, that it must have happened.
Just because you don't know how or why it happened.]]
Perhaps you are not aware of the fact that the DNA code for life is essentially arbitrary. (I'm sorry but I don't have time to explain that to you. It's one of those things you will learn about should you study Tobin and Dusheck's book mentioned just above.) Therefore, if life is not linked by evolution then we would expect a multitude of different DNA codes. If life is linked by evolution then we would expect to see the same DNA code throughout. The latter case is observed, so we have strong evidence that life traces back to one source. (If it traced back to two sources we would have two different DNA codes corresponding to the two lineages.)
[[I have not studied the cytochrome-C in particular so I need a bit of clarification here.]]
Is this video {site given} representing your evidence? {Haven't looked at it.}
Well that is not evidence of macro-evolution but evidence that cytochrome-C has been effected by those mutations throughout history in those species tested.]]
Take a look at this site: chemistry.umeche.main.edu/CHY431/Evolve2.html
It also includes the classic evolutionary "tree" derived from studies of cytochrome c. Before you start digging into your bag of rationalizations you might want to put in some study. Rather than dealing with the total nonsense you present here, I'll give you a chance to study. Understand how cytochrome c yields an evolutionary tree. Then present your objections.
Well, that's the last of the batch.
Jeff - "The Panda is a fine example of how easy it is for us humans to not know about an existing specie. (took us 60 years to find it after knowing it was there)"
The 'discovery' of the panda pre-dates recorded history.
Jeff - "ZANA, a possible Neanderthal that was captured by a Russian tribe"
More cryptozoology Jeff, although not surprising from someone who believes in Bigfoot and ancient aliens.
I have friends who have done the years and years of work and study to be called PhDs in anthropology and paleozoology. They are field scientists and university professors. I trust their word far, far more than I would trust the word of someone who spouts information gleaned only from various internet sites including YouTube. And interestingly, none of them is a pawn to the conspiracies some posters have accused scientists to be.
The old, grand conspiracy theory is the hallmark of every fruitcake organization that ever stumbled crossed the stage! You see it in flying saucer literature, in literature about the assassination of Kennedy, in the literature that denies that we ever made it to the moon, in literature about the "face" on Mars, in the literature of false healers and their supposed cures, and in literature that (insert your favorite here). Of course, it's in the anti-evolution literature as well. If you are a pseudoscientist and run out of gas, there's always the old conspiracy theory.
I find it fascinating that someone hit the disagree button for this post of mine. With which part do they disagree? That I do not know these people? That they do not have the stated credentials? That I actually don't trust them more than someone without that education and experience? Perhaps the disagreer has evidence of my friends' complicity in a conspiracy. Hmmm....
I suspect that the person who disagreed with my post either didn't read it or just didn't like it.
@ Greensnake : That was one of the best short explanations on evolution I have ever read.
Appreciate it, Charvak! Bye the way, if you have any favorite anti-evolution arguments that you would care to see discussed I'll do my best.
Greensnake - Best compelling, and energetic, work on evolution I've read lately.
Nyarlathotep - Marvelous link.
Thanks for the replies.
"Perhaps, English is a second language for you."
Yep it is, does it mean that it was not understandable?
Certainly not.
When someone doesn't understand something, he should ask for further clarification, not just ignore it.
Unless ignoring it was the real intention, and my claimed bad English was just the pathetic excuse.
If it was just on 1 or 2 of my points, I would never mention it, but you seem to ignore like 2/3 of all my points on purpose.
It is becoming too irritating at this point.
"Jeff, keep in mind that this is a forum!"
Yes, this is a place where people debate, and in mature debates people that make claims need to support them with proper quoting and references.
"I'm not going to write a textbook for you!"
I never asked you to do so.
Your reply to my questions should be in this manner:
My question:
Where is the evidence for claim a?
Your answer:
Here it is: "Quote" + Reference of paper.
(so some 4 lines on average)
What do I get instead:
-More unsupported claims
-Go read this/that book because you think it contains the reply for my question.
-pages and pages of accusations, contradictions and fallacies that you end up ignoring the moment I point them out to you.
"I'm not going to dig up endless references for common, scientific knowledge that was established many decades ago."
You BELIEVE that it is "common, scientific knowledge", while I am just challenging that belief.
People BELIEVED the earth was the center of the universe too and they too BELIEVED it was "common, scientific knowledge".
Now we learned the scientific method so we don't need to BELIEVE things anymore, we can go and actually support our claims in mature debates.
I am just asking you to support your claims.
If you do not wish to do it, then accept that you don't know the subject enough to defend your claims using the scientific method, thus you prefer to BELIEVE in it just like Pragmatic does.
"Even if I had the time, I would not waste it by duplicating any of the excellent works already in existence."
As I said, if there was evidence it would only take you 4 lines of text( for each claim) to point me to the evidence.
You do not need to explain anything at all.
"mining them for quotes!"
Lol, The evidence is self evident.
It is usually the main argument of any paper, you do not need to mine anything.
Books/sites that have interpretations and are filled with bullshit, yes they could make you mine for the actual evidence if there is any at all.
You basically proved my point.
(http://evolution.berkeley.edu and http://www.talkorigins.org)
Again, I have read some parts of those sites for other reasons, they are generic and anything related to macro-evolution is mostly either completely false or partially true.
They are not a reliable source of information on our topic at hand. Essentially they are propaganda.
If you wish to claim differently, then quote where they support your claims.
(eg how do those sites present evidence that prokaryotes macro-evolved in eukaryotes?)
[[It is important to note that all my questions must be answered to make the claim that the hypothesis is supported by logic/science, not just some of the questions.]]
[[1)First thing, it is basically evident in your claims that you fail to understand who has the burden of proof here.]]
"Not true! Suppose a flat-earther used the same logic and declared that his long list of questions all had to be answered in order for you to make the claim that the spherical earth hypothesis is supported by logic/science? Is that a sound argument?
OW man, this is becoming too irritating."
Can you stop the Straw-mans please?
How DARE you compare my lack of making a claim, to the claim of a "flat-earther".
I just asked questions about the facts that any hypothesis MUST explain.
YOU CANNOT MAKE/DEFEND A HYPOTHESIS/THEORY IF IT DOES NOT EXPLAIN ALL THE FACTS IT IS RELATED TO.
A hypothesis is an attempt at explaining ALL the facts with an idea/claim using evidence.
When enough evidence is presented it could become a theory.
Now, if with time new facts emerge, the hypothesis MUST also incorporate those facts if it is valid.
So you cannot dismiss and ignore ANY of my questions regarding those facts I pointed out.
YOU MUST ADDRESS THEM FOR THE HYPOTHESIS TO BE SCIENTIFIC.
"Regarding macro evolution, most attacks......"
I do not care what other attacks did or did not do.
It is irrelevant to your unsupported claims.
This is a typical "Guilt by association" fallacy.
"insignificant details and irrelevant points"
That is what you believe, not what you have demonstrated so far.
So far you have showed you cannot present a scrap of evidence for your claims and instead you have to resort to fallacies.
"Serious questions will rise to the attention of the scientific community (sooner or later) and be presented in the scientific journals, which allows other scientists to test them or plan further research."
Yes we agree, but what happens in reality is that "Serious questions" get ignored if they are not popular enough.
History proves it.
Over and over again, geniuses/skeptics that pose "Serious questions" get killed/ignored/ridiculed because they are not popular enough.
"(sooner or later)" could apply to your belief in macro-evolution too.
"Show me recent issues of "Nature" or "Science" (the leading scientific journals in the English language) that feature any "debate" over the basic fact of evolution."
Yep that is the problem of dogma.
You are basically proving my point, that it must be the truth since it is so popular not because it is scientific.
Argument of popularity fallacy.
"There is no hint of a debate over the fact of evolution."
Yes, that is a serious problem that should be addressed, that is why I am raising the issue in the first place.
How long can we afford to ignore the facts just because it is convenient to believe in macro-evolution?
Think how much more could we have advanced in any fields(related), if the money wasted on a contradictory hypothesis was spent on a hypothesis that actually explains all the facts not just some?
"In the scientific world evolution above the species level (macro-evolution) is treated as a settled issue. It is the starting point for today's research."
Yes, though they been at it not just today, for more then a 100 years, the progress in it is basically the same.
Nothing to present as actual evidence, but more contradictions to the facts when it comes to the explanation(that the hypothesis should have delivered from start).
"overthrow long established knowledge"
No, overthrow long established belief and dogma.
It is an uphill struggle, I do understand how the Wright brothers felt.
"meaning that you have to do more than pose questions and riddles as creationists do."
If creationists pose serious scientific questions on this subject they are more scientific then the Neo-Darwinists on this specific subject.
What motivates them is irrelevant if the questions are logical and scientific.
You should not have a bias and commit a Genetic Fallacy.
I do not see how the burden of proof is on me just because the majority thinks otherwise when THEY make a claim?
" The burden of proof is on your shoulders for the same reason that it is on a flat-earther's shoulders."
I am not making any claims, I looked at the facts and the facts say that species just appear in the fossil record without any intermediate fossils, many like me have noticed it( I quoted them).
Thus macro-evolution hypothesis to be scientific it MUST explain how that happened if Macro-evolution is what happened and not something else.
It fails at explaining even after putting the excuse for a 100+ years that the fossil record was incomplete.
Time proved that it has nothing to do with the incompleteness of the fossil record but that if there are intermediate fossils they seem to avoid getting in the fossil record for some unknown reason.
Punctuated equilibrium fails at giving a valid explanation for any species except the small fish in the pond apart from lacking an explanation for other aspects of their hypothesis.(which you failed to address in my previous posts)
"At some point a scientific debate often reaches a firm conclusion after which it would be silly to continue rehashing old arguments."
So if it is an old conclusion we must accept it as gospel truth? As if the scientific community was never wrong on old debate conclusions right?
(yes I used the word gospel on purpose :))
You know how religious that sentence sounded right?
"After that point, if someone wants to object, they have to convince the scientific community that they have a really hot argument."
yea, the belief that that is even scientific and not dogmatic, is also another problem with the scientific community.
That is why I said that you have to look at the scientific community as a Church when it comes to some topics which have been accepted as gospel truth for a long time.
"(knowledge that has passed rigorous tests)."
You BELIEVE it has passed through rigorous tests.
In fact to this day we still cannot even replicate a single macro-evolution in the lab.
So where are the rigorous tests?
Where are the artificially made eukaryotes from prokaryotes?
If nature did it randomly(by chance), it should be easy to replicate in a lab when we know what things are missing from a prokaryote.
All you need is to find the paper with the experiments, no need for a text book, just a quote and a link to the paper.(2 lines?)
I'm sure that those "excellent resources!" you wanted me to read make it very easy to find.
"Do all that and you can be another Einstein"
You know that Einstein lost most of his Nobel nominations because he died before his ideas were even accepted even though he had the scientific method and evidence to back up his theories?
Why?
Mainly because the scientific community is not as scientific as they wish to make you believe, but they are more about popularity at the time.(basically money/power/status)
"The size of the deflection was exactly as Einstein had predicted from relativity in 1915. The prize should have been his, but the committee snubbed him again."

"I made my arguments and I referred you to this excellent summary of the evidence. Nothing wrong with that! Referring to a body of factual evidence is not a cheap substitute for reasoning!"
A summery is an interpretation, while if you have any evidence you would just go strait to the evidence.
You do not need interpretations, go to the paper that describes the experiment,
Show what the book presents as evidence.
"lists numerous fossils and their observed relationships"
Yes point them out, since I am actually challenging those "observed relationships".
I studied some of them and they are not evidence but could be easily dismissed as another specie entirely, like the whale case.
"Nothing wrong with that!"
Yes it is wrong, I am asking for evidence and you are giving me the opinions of people on those claimed evidence.
This is like asking to talk to god and they would say that ONLY through the interpretation/priest you can talk to god.
I am sick and tired of asking the same questions over and over again, I want the evidence, not the opinions of people on the evidence.
You have to understand that most of these guys have been thought this as a given, they do not think outside of the box they were caged in, what appears to them as evidence might be their biased opinion because they assume macro-evolution.
This shows up in their papers too so i tend to expect that books authors do the same.
"Referring to a body of factual evidence is not a cheap substitute for reasoning!"
It is if the evidence is represented by a guy who filtered the ones he likes because he is biased on macro-evolution.
He does not have the perspective of an open minded person that takes everything into consideration.
Thus if he finds something that does not help his case, he will ignore it and miss that it actually hinders his case instead of just being irrelevant.
This happens often in any line of research, since it is very easy to miss important aspects when you are not looking for them.
Evolutionists are looking just for aspects to support macro-evolution, not for aspects that challanges it, that is why you don't find books written like Darwin's own paper, where he tries to challenge his own ideas.
That is a true scientist.
"(Yes, some people do have a habit of referring us to this,..."
You won't believe how every single evolutionist does it to me.
"(Some of your questions and points led me to believe that you might benefit from this book.)"
Thanks, I will read them for my own research.
"Am I ignoring something important?"
yes, You are ignoring the most important.
If macro-evolution is a scientific hypothesis, it MUST explain the facts. It must offer an explanation of the facts.
It is its main purpose.
Yet, it does not explain anything at all, it does not explain why or how it happens, it just doesn't.
There is no science behind it, there is no Nature Selected this or that. There is no this mutation does this or that.
Nature can do anything, who needs science?
If you cannot even show that macro-evolution cannot even reach the level of a scientific hypothesis, then you cannot say it is scientific.
It is a belief, you have to believe it on faith that it happens.
I can come up with better hypothesis in minutes which are not supported by evidence, but you do not need to believe them on faith either since they fit all the facts, not just some.
"When debating Bible-believers I often point out that serious Bible scholars reject the notion that the Gospels"
Yes but Bible-believers are not skeptics that are asking for evidence from an Evolutionist believer.
They are making a claim and the burden of proof is on them.
"If it is widely accepted by the experts, then I don't always feel a need to dig up some token quote."
That is an argument of Irrelevant authority fallacy.
You assume someone is an expert on this subject but in truth none is. A lot think they are yes and they write books on it.
This is a highly theoretical subject and practically everybody is shooting ideas left right and center.
The scientific community thought we descended from Neanderthals just 15 years ago and they were proven wrong by geneticists.
Jeff-"I do not read troll posts"
"Why do you disparage them by calling them "troll posts"? "
Straw-man?
I did not call them troll posts, I call Nyarlathotep posts as "troll posts".
He trolls and tries to provoke a flame war and some most disgraceful forum members think that this is acceptable on a forum. They also encourage him to do it more by claiming that he is not trolling at all. Shameful but one would expect it from dishonest people.
"Judging by many of your questions and arguments, you definitely need to study them along with Dr. Prothero's book."
Yea I respect your judgments even though I disagree with it, I think you should be the one actually learning to filter the bullshit.
"Fail to support? Half this post is spent correcting your basic misconceptions about evolution!"
I am pretty sure I addressed every single point you raised and nowhere there you corrected any misconceptions I had, more like pulling fallacies one after the other and thinking they are misconceptions.
"What background do you have?"
This is the problem.
You still cannot be scientific about the subject.
What background could I possible have to help me on this subject which deals with so many topics?
Or are you going for the genetic fallacy?
This is a topic that unless you did a full thesis on(for yourself), you won't get the necessary knowledge about it since it is so big, that usually what happens is that they specialize in a workable components of it like genetics, ethnology, archaeology etc...
So you either love the subject(search for the truth) or you won't know much about it.
No field of work will get you anywhere close on the full picture.
(for the evolution topic alone I had to study: bacteria, skulls, footprints, fossils, dna, rna, history of some animals, dating methods, the solar system, tectonic plates, catastrophic events/extinctions, most apes discovered, teeth, etc...)
"Research papers would be hard for a layman to read and they are very narrowly focused. Most people would not get much good out of them. Bill Nye's book covers all kinds of common misconceptions about evolution in a very friendly way."
Friendly way means, let him filter the evidence for you.
You should stick to the papers when it comes to important issues like the evidence for macro-evolution.
If Bill Nye's book is a good book as you claim, then it should make it easy to access where it is supported in the papers.
"Sometimes scientists may be slow in accepting something new, such as Darwin's evolution or Einstein's relativity, but that is only temporary."
Yes but some aspects of Einstein's relativity have not been accepted to this day.
Sometimes they may just bury it completely like what they did to Tesla, when he was proposing energy via wireless.
NO ONE funded his research even though he showed it is possible and also had credibility with his previous discoveries.
Why?
Politics/money/power were not on his side, his idealism was not popular at the time with the scientific community.
You are naive to think that the scientific community is not shaped around those factors.
If science is in accordance with those factors it happens and if not, it simply stops being scientific.
This is not some major conspiracy, it is human nature, everybody looks after his own interests.
Few would choose to lose their job by researching a subject which hinders their employers.(like what Tesla did)
Even fewer would succeed like the wright brothers.(they had to build the plane themselves).
"They are not nearly as dogmatic"
I did not say all scientists are dogmatic or that scientists are dogmatic.
I said the scientific community is dogmatic on some old concepts.
"Scientists win awards by finding errors in accepted ideas, not in defending them!"
Yea, only if the errors are accepted by the scientific community which decides what is OK or not.
Can't you see that if I find an error in macro-evolution, I won't get an award because that subject is not OK to find errors.
I will get ridiculed, called a conspiracy theorist, called that I know nothing on the subject, asked to go read a book etc...
"Scientists rejected Darwin at first because the scientific community, itself, was almost entirely creationist!!"
That is a myth, yes a good part was, but most were not.
First of all Darwin published his paper in a way to be liked by creationists.
He mentions god both at the beginning and at the end of his paper Origin of Species.
Eg:"There is grandeur in this view of life, with its several powers, having been originally breathed by the Creator into a few forms or into one"
https://www.goodreads.com/reader/3861-on-the-origin-of-species?percent=9...
In fact just 10 years later after his release of the paper they must have converted from creationist to Darwinist/naturalists right?
Since they made a U-TURN and most supported Darwin's idea now.
"especially younger scientists"
It had nothing to do with younger scientists more to do with politics.
The idea was liked by both the scientific community and the creationists, thus it did not cause much inter-denominational religious strife except for some fundamentalists.
"by the time Darwin died, his theory had been accepted by the scientific establishment and was well on the way to being accepted by the Church too."
https://www.darwinproject.ac.uk/darwin-and-religion-america
Seriously man filter the bullshit.
The scientific community never wanted religion thought in schools because of religious differences and this predated Darwin's paper. Then later in 1925 a heated debate started and the scientific community chose to side with Darwin's idea instead of removing it until there was concrete evidence because it was convenient.
The creationists main argument was:
If you (scientific community) do not know what happened, let us teach the children a possible scenario.
Darwin's idea was a better alternative against this argument.
"I am shocked!"
You should be, the scientific community first adopted the idea because it was convenient and then it kept macro-evolution thought to children without any real evidence to back it up, again for convenience.
"10,000 scientific papers all based on hidden nonsense??"
If they all just assume macro evolution and just build on it, yes they are as based on nonsense as a castle built on sand.
"it is very clear to me that the vast majority of scientists go into science because they want to explore the unknown."
Yea that surly is the case at first, but when you get down to reality, and understand that you need to feed your family, you start to think differently.
"They are very much interested in the truth!"
Sure but some are but very few are motivated enough to risk ending up on the streets jobless.
In the end most of those who are "interested in the truth!"would just avoid the subject in an official capacity.
"Science is a self-cleaning operation."
Science is, but the scientific community is not especially when it is influenced by politics, power and greed.
"But isn't it also your duty to know something about the subject that you criticize it?"
It is my duty to know the subject, it is not my duty to read all the interpretations of those subjects, just like it is not my duty to read all versions of the bible when debating a creationist.
That is why I am very insisting for you to go strait to the evidence(source) instead of sending me to read books and sites which are probably filtered interpretations that influenced your current belief.
I apologize if there are some replies which are addressed in the next posts which I haven't read yet.
I will reply to the rest of your posts when I have time.
Jeff - "What do I get instead:...More unsupported claims"
When you are a conspiracy theorist, anything that contradicts your world view is an unsupported claim---by definition---because the theorists can (and typically will) dismiss anything that does not fit as part of the conspiracy. If essentially every biologists on the planet disagrees with you? Simple, just claim they don't really disagree but they are being forced into saying it because they will lose their jobs. 10's of thousands of peer reviewed articles disagree with you? No problem, they are part of the conspiracy as well! A conspiracy theory is an infinite hole, you can toss as much inconvenient material into as you need. Don't get me wrong; conspiracies do happen, but we should be very careful before embracing them as an explanation because of the above problem. A good rule of thumb is to consider how many conspirators are required. The more people it requires, the less likely it is to be an accurate explanation.
---------------------------------
Jeff - "(http://evolution.berkeley.edu and http://www.talkorigins.org)...They are not a reliable source of information on our topic at hand. Essentially they are propaganda."
The conspiracy widens to include the Universe of California at Berkeley (typically regarded as the top university in the world for science).
---------------------------------
Jeff - How DARE you compare my lack of making a claim, to the claim of a "flat-earther".
It seem like a pretty good comparison, since both require a conspiracy of millions of scientists, many at the top centers of learning around the world.
---------------------------------
Jeff - "You know that Einstein lost most of his Nobel nominations because he died before his ideas were even accepted even though he had the scientific method and evidence to back up his theories?"
WTF are you talking about? Einstein's work was essentially universally accepted by the time he was in his 40's. That's pretty darn good for a physicist! I also see some rather nasty cognitive dissonance in your above statement since you have told us previously that general relativity is fundamentally flawed. Also they don't issue multiple Nobel prizes in physics to the same person (the exception is if you get one, then later work with someone on a new project, to keep from short changing your new partner you can receive a 2nd as part of the group, and even that is rare).
---------------------------------
Jeff - "You have to understand that most of these guys have been thought this as a given, they do not think outside of the box they were caged in, what appears to them as evidence might be their biased opinion because they assume macro-evolution."
Dunning–Kruger effect: https://en.wikipedia.org/wiki/Dunning%E2%80%93Kruger_effect
Also note that this creates additional cognitive dissonance. On one hand you tell us it is a conspiracy, on the other you tell us that biologists are incompetent (or at least that you are more competent than them).
---------------------------------
Jeff - "[Nyarlathotep] trolls and tries to provoke a flame war and some most disgraceful forum members think that this is acceptable on a forum. They also encourage him to do it more by claiming that he is not trolling at all."
I don't think that calling a spade a spade is trolling. I don't think holding someone accountable for previous posts in other threads is trolling. I admit I do both of these things; so if you can get a site admin to state unequivocally that those actions are a form of trolling, I will leave the site.
---------------------------------
Jeff - "What background could I possible have to help me on this subject which deals with so many topics?"
Well perhaps you could start by learning about the long list of transitional fossils that have been found (you know, the ones you keep telling us don't exist?).

Based on your posts, no need to leave, Nyar.
Jeff,
Thank you for your patience.
[[If it was just on 1 or 2 of my points, I would never mention it, but you seem to ignore like 2/3 of all my points on purpose.]]
Many times you interpret my points in strange, confused ways and then, because of that, ask irrelevant questions and make irrelevant attacks. When that is combined with your abbreviated writing and the fact that English is a second language, the result becomes such a tangle that I have no choice but to ignore it. You question endlessly ideas that science accepts as basic facts, ideas that are covered in great detail in textbooks and other places. Sometimes I just get tired explaining things that you can easily read. Also, when you make bald-faced proclamations without support, sometimes I don't feel obligated to answer them.
[[As I said, if there was evidence it would only take you 4 lines of text( for each claim) to point me to the evidence.]]
What you are really asking for many times are complicated explanations that require a great deal more than 4 lines of text! Example: Explaining the richness of the fossil hominid record. Example: Explaining the evolutionary "tree" and why it proves macroevolution. When that explanation is already in a book, and I point out the book to you, you should study it.
[[(http://evolution.berkeley.edu and http://www.talkorigins.org)
Again, I have read some parts of those sites for other reasons, they are generic and anything related to macro-evolution is mostly either completely false or partially true.
They are not a reliable source of information on our topic at hand. Essentially they are propaganda.]]
This is just your opinion which means nothing since you are not an expert. Why do you constantly offer your unsupported opinion? These sites are offered as general background study, so there is nothing to quote. For example, they explain what an evolutionary "tree" is. If you are going to call such excellent sites "propaganda," as though your opinion settles it, then why even ask me to quote authoritative sources? To say it another way, if expertise means nothing to you in these sites then what is the point in asking for quotes? Aren't they just more expert opinions?
[[It is important to note that all my questions must be answered to make the claim that the hypothesis is supported by logic/science, not just some of the questions.]]
[[1)First thing, it is basically evident in your claims that you fail to understand who has the burden of proof here.]]
"Not true! Suppose a flat-earther used the same logic and declared that his long list of questions all had to be answered in order for you to make the claim that the spherical earth hypothesis is supported by logic/science? Is that a sound argument?
OW man, this is becoming too irritating."
Can you stop the Straw-mans please?
How DARE you compare my lack of making a claim, to the claim of a "flat-earther".]]
The point is this: How much time must I spend answering questions that are irrelevant because they deal with a confused idea of my arguments or of standard scientific concepts? You seem to have the idea that if I don't answer every one of these questions I must drop my point. I don't like to spend great quantities of time on questions that are not a threat because they miss the point and lead down some side alley.
[[So far you have showed you cannot present a scrap of evidence for your claims and instead you have to resort to fallacies.]]
Are you saying that the evolutionary "tree" relationship diagram is not evidence?? If you can not see that as evidence, then truly there is nothing that could ever count as evidence! Why is there no discussion about this central evidence for macroevolution?
[[Yes we agree, but what happens in reality is that "Serious questions" get ignored if they are not popular enough.]]
If we look at recent times, which we have to do if we are talking about an authoritative scientific community, the answer is right before you! Darwin was ignored at first because his idea was not popular. Einstein was ignore more or less until the solar eclipse of 1919 proved him right. Rachel Carson (author of Silent Spring) was ignored and even attacked because she exposed the poisons industry was dumping into the environment. They get ignored only for a while unless they are totally wrong.
[["Show me recent issues of "Nature" or "Science" (the leading scientific journals in the English language) that feature any "debate" over the basic fact of evolution."
Yep that is the problem of dogma.
You are basically proving my point, that it must be the truth since it is so popular not because it is scientific.]]
Who says these journals are not scientific--you?? What are your credentials? These journals are exactly where the world's best and most important research is reported! If there is no debate there over the fact of evolution, then there is no real debate among real scientists anywhere in the world. You are wrong. Unpopular ideas do get published in these journals (remember cold fusion? Remember the 5th fundamental force?), but they must be presented by competent scientists and at least look believable. Attacks on the fact of evolution (as versus details) are not published because they are not good science, not because they are unpopular. That issue, your opinion notwithstanding, was settled long ago.
[[Argument of popularity fallacy.]]
Totally wrong!
[["There is no hint of a debate over the fact of evolution."
Yes, that is a serious problem that should be addressed, that is why I am raising the issue in the first place.
How long can we afford to ignore the facts just because it is convenient to believe in macro-evolution?]]
There is no debate because the issue has been settled among real scientists. Macroevolution IS the truth and not merely some convenience. (How could it be a convenience?) Nothing is being ignored except bad arguments (mostly from people with no credentials) who refuse to accept the truth. Asking that scientists reopen the question is like asking that they reopen the question of a 6000-year-old Earth!
[[I am not making any claims, I looked at the facts and the facts say that species just appear in the fossil record without any intermediate fossils, many like me have noticed it( I quoted them).
Thus macro-evolution hypothesis to be scientific it MUST explain how that happened if Macro-evolution is what happened and not something else.]]
The explanation is called "punctuated equilibrium." I've pointed this out many times! How is it that you still claim that this is a big mystery??
[[Punctuated equilibrium fails at giving a valid explanation for any species except the small fish in the pond…]
Pure nonsense! You have in no way discredited punctuated equilibrium. Mostly, you give us unsubstantiated opinions as though they are general truths. If not that, we get confused arguments that show no understanding of punctuated equilibrium beyond a few basic, disconnected facts. Before you can discredit some idea you have to know what it is all about. That means the details, the stuff of university textbooks.
[[Where are the artificially made eukaryotes from prokaryotes?
If nature did it randomly(by chance), it should be easy to replicate in a lab when we know what things are missing from a prokaryote.]]
Nature also makes potatoes. So go into your laboratory and make a potato! It should be easy if you know what ingredients you need. These kinds of arguments are crazy!! That's why they get ignored. Has it occurred to you that nature took a billion years? You can't simulate a billion years of evolution in any laboratory.
[[All you need is to find the paper with the experiments, no need for a text book, just a quote and a link to the paper.(2 lines?)]]
More craziness!! Now you want me to dig up a paper based on your crazy argument above, an argument I don't even support because it is crazy, an argument based on nothing more than an ignorant opinion! I'm supposed to waste time searching for something that doesn't exist; no scientist would ever make such a claim. This is why much of your stuff gets ignored.
[[I am sick and tired of asking the same questions over and over again, I want the evidence, not the opinions of people on the evidence.]]
There is nothing I could possibly offer you that you would not reject on the basis of your unsupported opinions, your grand proclamations, and much of the evidence you ask for is just plain crazy (as pointed out above) or based on confused understandings. I offer the world's leading scientific journals. Nope, not good enough for you. I offer university textbooks. Nope, not good enough. Nyarlathotep offered especially excellent Internet sites. Nope, they are just propaganda. I offer the consensus of the scientific community. Nope, they reject unpopular ideas. I offered the evolutionary "tree" relationship that proves macroevolution. You mostly ignored it--no detailed discussion at all. It is now clear to me that your rejection of macroevolution is not going to change no matter what anyone says. I suspected that from the start but I wanted to challenge you with some of the facts. Unfortunately, you can't even connect with these facts to give a coherent reply.
[["Am I ignoring something important?"
yes, You are ignoring the most important.
If macro-evolution is a scientific hypothesis, it MUST explain the facts. It must offer an explanation of the facts. {It does! It does!}
It is its main purpose.
Yet, it does not explain anything at all, it does not explain why or how it happens, it just doesn't.]]
You are confused as to what needs to be explained, because you don't understand evolution (macroevolution). All we get (once again) is your opinion and you are hardly an expert here.
[[There is no science behind it, there is no Nature Selected this or that. There is no this mutation does this or that.
Nature can do anything, who needs science?]]
More bald-faced opinions from yourself (you're not an expert), more confusion about natural selection. Listen carefully: Natural selection is a general principle based on several axioms. When those axioms are met, natural selection is possible. It's a matter of logic that can even be applied in industry. You seem to have mistaken natural selection (a general principle) for a statement about the details of how each species evolved. Such details are usually not available, but we know that each type of environment applies its own selective pressure. (As for specific mutations, in one of my later posts I gave you some examples. Perhaps you have not yet read them.)
[["What background do you have?"
This is the problem.
You still cannot be scientific about the subject.
What background could I possible have to help me on this subject which deals with so many topics?]]
Nobody is asking you to be an expert in all of the related fields! Even Stephen J. Gould wasn't. At the very least you need to understand what you criticize--the basic ideas of evolution. That means studying a university-level textbook on biology. Evolution relates to the whole of biology. It's not that hard but it does take time if you do it right. If you want to challenge accepted science, then you had better have a PhD and a research grant otherwise no one will take you seriously. Nor should they. For these forum debates, anything, even the basic primer by Bill Nye, is better than nothing.
[["Research papers would be hard for a layman to read and they are very narrowly focused. Most people would not get much good out of them. Bill Nye's book covers all kinds of common misconceptions about evolution in a very friendly way."
Friendly way means, let him filter the evidence for you.]]
So, you have restricted yourself to research papers that you don't understand? Research papers don't teach the basics, and you have not even mastered the basics judging by your debate. Give Bill Nye a try. You might actually learn something if you can get out of your denial mode.
[[If Bill Nye's book is a good book as you claim, then it should make it easy to access where it is supported in the papers.]]
Of what possible use are citations of research papers in a book introducing a reader to general principles? Research papers ASSUME general principles in their narrowly focused studies. Furthermore, a reader who is just learning the basics is hardly going to be able to read a research paper anyway! It is filled with technical jargon and assumes its reader is well aware of the basics. Then you demand that Bill Nye's book must live up to this insane criteria if it is any good! This is just plain nuts!!
[["Scientists win awards by finding errors in accepted ideas, not in defending them!"
Yea, only if the errors are accepted by the scientific community which decides what is OK or not.]]
Horse manure!! A hypothesis is in error when it does not make correct predictions. It's something every competent researcher can see, not something voted on by the establishment. Where do you get these ideas?
[[Can't you see that if I find an error in macro-evolution, I won't get an award because that subject is not OK to find errors.]]
Your chance of finding an error in macroevolution is ZERO because you don't even know what it is! If you do reach the point where you know something about macroevolution, you would still lack the advanced knowledge to do serious research. You have not gone beyond armchair speculation of the worst kind!
[["Scientists rejected Darwin at first because the scientific community, itself, was almost entirely creationist!!"
That is a myth, yes a good part was, but most were not.]]
Hit the history books!
Sorry, but following your arguments (which I see as nothing more than a series of bald-faced assertions punctuated by confused concepts) is like going down the rabbit hole in Alice and Wonderland. You need to take a break from denying evolution and actually do some study. Bill Nye's book is a good place to start. You may even find it interesting.
It's about time for me to take a good look at some of the other forums. In this one we are just talking past each other, so we should give it a rest.
Jeff,
