In addition to being
the bananaman, Ray Comfort is the co-popularizer of the
crocoduck. Comfort believes that because modern biology shows that birds are descended from theropod ancestors, there must be a transitional form between extant birds and extant reptiles; hence a half-crocodile, half-duck.
Here's the video in which Comfort's ex-child actor sidekick Kirk Cameron made that claim.
That general false claim--the claim that evolution predicts that there must be an evolutionary pathway directly linking two extant organisms or extant biological structures--is not unique to creationist loons, though. Doug Axe has posted
a response to
Paul McBride's review of "Science and Human Origins" on ENV, and has disabled comments on his post. I won't elaborate, but will note that an amusing part of Axe's response is this:
Ann [Gauger] and I conducted experiments to find out how many changes would have to occur in a particular enzyme X in order for it to begin performing the function of another enzyme, Y. We found that they are too numerous for unguided evolution to have accomplished this transformation, even with the benefits of a massive bacterial population and billions of years. Having carefully made the case that our chosen X and Y are appropriate for the aims of our study, we think this result has catastrophic implications for Darwinism.
As has been shown, though, the research that Axe cites,
The Evolutionary Accessibility of New Enzymes Functions: A Case Study from the Biotin Pathway,
does not test an evolutionary hypothesis. By studying whether one extant enzyme in a family of enzymes could have evolved from another extant enzyme in the same family, when the evolutionary account is actually that both evolved from a common ancestor, Gauger and Axe are making precisely the same error that Comfort and Cameron made: the notion that "common descent" means that related extant populations evolved from each other, rather than from a common ancestral population. That about equivalent to claiming that common descent means that I am descended from my cousin Keith.
Even young-earth creationist biochemist Todd Wood
rebutted that particular claim more than a year ago. Wood wrote
Instead of ancestral reconstruction, Gauger and Axe focused directly on converting an existing enzyme into another existing enzyme. That left me scratching my head, since no evolutionary biologist would propose that an extant enzyme evolved directly into another extant enzyme. So they're testing a model that no one would take seriously? Hmmm...
Axe and Gauger quite simply didn't test an evolutionary hypothesis in the paper Axe cited, but Axe continues to claim that it says something about the limits of evolution. But when even an honest young-earth creationist sees the error, persisting in it is no more than perverse. Axe is doing the equivalent of waving Ray Comfort's crocoduck over his head, hollering "Evolution couldn't do it!" Maybe Ray will have an opening in his ministry for Axe when the BioLogic Institute sinks beneath the waves.

And, by the way, there's a good model for how to do research on protein evolution. See here for a review and here for an example.

Thanks for the references Richard.
The creationists have a choice, they can persist in their mischaracterizations and lose all credibility, or they can admit that modern evolutionary biology is a productive field with the real experts making advancements every day while they wallow in ignorance.
Perhaps Ray would like to address the actual science, not his mischaracterizations. Perhaps not. Perhaps Ann would like to explain the methods she used in her "experiments" to reconstruct ancestral character states. Perhaps not.

1) Could any evidence convince you of the theory of evolution, and if so, what type of evidence is now lacking, that would convince you if present?
2) The Supreme Court ruled against the direct teaching of Biblical Young Earth Creationism as science in public schools; however, if that ruling were overturned, which would you support more, teaching of ID, or direct teaching of Bible-based YEC?
3) Do you think it is important for opponents of the theory of evolution to fully understand the theory of evolution? If so, can you explain it, and if not, can you explain why not?
4) Who is the designer? How can we test your answer?
5) What did that designer do? How can we test your answer?
6) How did the designer do it? How can we test your answer?
7) When did the designer do it? How can we test your answer?
8) What is an example of something that was not designed by the designer?
9) Some parts of the Bible suggest that pi equals exactly three, and that the earth is flat and has four corners. Do you accept these as facts of physical reality, and if not, why do you deny the theory of evolution on the grounds of Biblical literacy, if it can be symbolic about other scientific issues?
10) Can you please summarize what Axe and Gauger have done in your own words, and explain, in your own words, without cutting and pasting, what it has to do with the theory of evolution?
Get ready, chirping crickets and lonesome howling coyotes, because you're going to be the only ones answering these questions.

Flint · 20 July 2012
Mike, I think you're on the right track there. There is always an underlying inability to grasp the notion of evolutionary change. It nearly always gets depicted as some CURRENT organism "evolving" into some other CURRENT organism. God created all the organisms there were and always will be, so what else could evolution BE? So they seem convinced that ONE of these enzymes must be the "common ancestor", could be any of them, so just pick one.
Maybe if you pinned these folks into a corner, they might conceded that, well, yeah, there probably WAS a common ancestor -- but it would have to be "almost just like" all the rest of the family. Nothing new is ever created; the Designer isn't in that business anymore. Since they are doing all this science to demonstrate the necessity of the "theory of poof", a genuine evolutionary hypothesis simply does not fit the model.

We all know creationists are putting on a show for those who don't know anything about science, detest science, and/or are so religious they'll believe anything fed to them that to them sounds reasonable as long as it doesn't contradict their religious beliefs. And we know they're full of crap, whereas true scientists/investigators can produce tons of evidence and experimental results, but creationists are only after the PR battle, not facts, and people shun reality, it threatens their psychological well being and their dream world. Thus creationists know they have to constantly preach to the choir and make their pseudo-science efforts look like science, that's all.

Maybe we can make it easy for them. Can you turn a chimp into a human? No, there are too many changes that need to occur. But, starting with a common ancestor, you can get divergence of two reproductively isolated lineages and presto, chimps and humans. The evidence that this in fact did occur is overwhelming, to deny it is to deny reality.
Now maybe Mr. crocoduck would like to tell us how his "model" represents common descent. Maybe Mr. "can't turn one protein into another" would like to tell us how his model represents an evolutionary hypothesis. Maybe these guys would like to explain why the papers using reconstruction of ancestral character states are published in real journals and their made-up nonsense is not. Maybe they would like to explain exactly who it is they think they are fooling and why they are trying to fool anyone. If they realize that their misrepresentations and distortions are dishonest, shame on them. If they don't realize this, more shame.

"Our results indicated that a minimum of seven mutations would be required to convert or reconfigure one enzyme toward the other’s function. No one disputes that part of our research."
So, if you started from the ancestral sequence, probably only three or four changes would be required in each lineage. No one disputes that part either. So why didn't you mention that? And why leave out the part about changes in duplicate gene copies of the ancestral sequence and lack of functional constraint in intermediates?

Is it out of place to use the drunkard's walk metaphor?
I'm thinking you could emulate this in a graphic and understandable way by having a dozen automobiles start from the same place. Let's give them gas tanks that only hold enough to cover ten miles. Let's further say that ever hour or so, each automobile becomes two, which continue independently.
At every intersection, each driver flips a multi-faced die to determine which direction to take (including the possibility of reverse or standing still.)
After a day or so we note the positions of the autos, and using Axe's methodology, we determine the probability that they all started from the same point by calculating the probability that two will converge in the future to the same location.

You reject your old hypothesis and construct a new one, then test it rigorously. If you are not willing to do this, then don't bother to look at any evidence. What is the point if you are not going to be honest enough to accept the conclusions? What you can't do is claim to honor the evidence then ignore it when it becomes inconvenient. What you can't do is continue to misrepresent the evidence when it has been pointed out to you that your are constructing a straw man. What you can't do is claim that your beliefs are based on the evidence when they are contrary to all of the evidence. That is dishonest, plain and simple. If you choose to do that, you shouldn't expect to get away with it.

I suppose one can argue that creationists are ignorant, stupid and wicked. And they were all of these things, incorrigibly, by the age of 7.
One can only marvel at the malleability of the infant human mind, that such irrecoverable damage could be done, so that even as educated and competent adults, they STILL can't help being ignorant, stupid and wicked.
We should all be thankful we were fortunate enough to have sane parents. But I find the creationist efforts to rectify the irreconcilable to be fascinating and complex, and I wonder at the layers within the phenomenon of consciousness that result in compartmentalization, rationalization, and doublethink.
Your "who cares WHY people commit crimes, just lock 'em all up" approach doesn't even address the symptoms, much less the problem. As I see it, the problem is the powerful grip superstition has on our minds. So long as people believe in gods, people will doublethink because they must. Anyone who can believe in gods can believe in anything.

No one has explicitly mentioned one possible contributory factor to implacable religious conviction, namely mental disorder.
I suspect that for some believers, or perhaps all to some extent, there is malfunction of the cognitive mechanisms which distinguish reality from fantasy. It seems to me that there is a compulsive-obsessive component to this kind of belief. In these ways and others, religious belief appears to be similar to delusional disorders.

This is a fascinating discussion, but I think it's missing the point. If creationists were like the Amish, no sympathy would be necessary. They'd be happy believing what they do, and leaving the rest of the world alone. But too many creationists are aggressive about their beliefs, and that kind of behavior isn't worthy of sympathy. Opposition and ridicule are their reward. I don't care if they're sincere, or what goes on in their heads.

It's the plain idiocy of it that gets me. Axe and Gauger were flailing at a straw man caricature of evolution, using fundamentally false assumptions about it. This was pointed out with breathtaking clarity by Paul McBride, by stating precisely what the theory actually says. And SteveP's take on this? That only "evolutionists" know what the theory says.
Yeah, well. Maybe so. That could conceivably be because they're the ones who study it and try not to misrepresent it.
Robert Byers · 22 July 2012
As a card carrying creationist loon I would still say fossils are not part of biological investigation for relationships, if any, between biological items.
Case in point are these conclusions about connecting birds and dinos because of some like details in some fossilized creatures under the terms of birds and dinos.
Its all lines of reasoning and nothing more.
Just because one lays eggs does not make a dino related to a bird or related to a lizard.
Many lizards and snakes don't lay eggs and many do but they are still lizards and snakes.
Laying however does not make a t rex a big bird.
They could, and did, just lay eggs because it suited them. yet this detail and others in which relationship is drawn between birds and dinos is just guessing.
Even if true it still would be guessing based on somebodies classification system.
it was just lack of imagination to figure out the option that having like anatomical details is for like needs and a ceiling to options for biology.
In fact evolutionism is increasingly forced to set limits to options for biological origins and change because of the increasing awareness of how much convergence there is in nature. or as they call it convergent evolution is forcing conclusions of fewer options for how structures and functions in biology work.
its all been a grand error of presumption.

Same thing with DNA fingerprints they ain't alive either so they are just wrong claims as evidences. cant draw conclusions on relationships from DNA its all false assumptions and not biological evidence. its atomic and unproven just like fossils is just rocks

Steve P. -
When you don't even answer a question on a test, you still get a grade - zero.
Here are some more questions you can't seem to answer.
Part A
1) Since you're so in love with Axe and Gauger's research, demonstrate that you have a clue what they did by describing their experiment and conclusions in detail. No need to criticize. Just explain what they actually did. Use any source material you need.
Part B
1) Could any evidence convince you of the theory of evolution, and if so, what type of evidence is now lacking, that would convince you if present?
2) The Supreme Court ruled against the direct teaching of Biblical Young Earth Creationism as science in public schools; however, if that ruling were overturned, which would you support more, teaching of ID, or direct teaching of Bible-based YEC?
3) Do you think it is important for opponents of the theory of evolution to fully understand the theory of evolution? If so, can you explain it, and if not, can you explain why not?
4) Who is the designer? How can we test your answer?
5) What did that designer do? How can we test your answer?
6) How did the designer do it? How can we test your answer?
7) When did the designer do it? How can we test your answer?

Here are some more questions for Steve P. (even if he doesn't have the guts or brains to answer):
1) WHat would one expect to see if two chromosomes fused? What telomeric sequences would be expected? What centromeric sequences would be expected?
2) What do we observe in human chromosome two? Is it what one would expect to see if two chromosomes fused since humans and chimps last shared a common ancestor?
3) Why is the telomere in the center of human chromosome two degenerate? Is this expected if it is the result of a chromosomal fusion?
4) Why do humans and chimps have exactly the same genes in exactly the same positions on all of the chromosomes (i.e. synteny)?
5) Why are humans and chimps the most closely related species genetically for both mitochondrial and nuclear genes?
6) Why do humans and chimps share many unique SINE insertions?
7) Why is there a nested hierarchy of genetic similarity in primates that is the same for chromosomes, mitochondrial genes, nuclear genes and SINE insertions?
8) Why do you think that the claim that modern chimps cannot turn into modern humans is a real scientific hypothesis?
I predict that Steve will not answer any of these questions. I predict that he will do nothing but throw out meaningless personal insults and completely avoid all of the real scientific issues. In other words, he will engage in exactly the same dishonest tactics as those he seeks to defend.
TomS · 24 July 2012
What I'd like to hear about is, if the great similarity between humans and chimps is due to "intelligent design" ...
Does that mean that there is a common purpose behind the design of humans and chimps?
I know that if the similarity is due to common descent, or any other purposeless natural regularities, or even if it is due to random chance, that means nothing at all. But if it was purposefully done, well doesn't that mean that we should tell our kids that they were purposefully designed to be like chimps?
