ISTM you have drawn first blood in this duel.
1) It's still a duhh-bird, duhh-theropod, -duhh dinosaur, -duhh
reptile, -duhh fowl.
2) It has a wishbone, just like a theropod. Therefore, it is still a
theropod.
3) The feathers were drawn in on both sides of the limestone.
Therefore, it is fake.

Could I take a crack at it?
To be a transitional fossil implies that it's a transition between some
predecessor species and some successor species in the so-called
evolutionary tree.
Have those been identified in the case of Archaeopteryx?
Isn't it possible that Archaeopteryx represents some kind of
evolutionary dead end that left no avian descendants? The actual
transitional species between reptiles and birds--the common ancestor of
all birds--might still be some other species than Archaeopteryx.
As dinosaurs began to evolve feathers, there may have appeared a number
of different species that started to look more bird-like. But how can
we know which one is the common ancestor of all birds?
-- Steven L.
Take your pick:
1. Because it exists.
Therefore it can't be transitional.
It can only be transitional if it doesn't exist.
2. Because it's a 100% modern bird, and if it's a bird it can't be a
dinosaur. Any differences between archaeopteryx and a modern bird are
either
a) frauds perpetuated by atheists or
b) irrelevant because it's a 100% modern bird
3. A true transitional would be a fossil with only half a wing
(presumably the distal end) and archaeopteryx has fully formed wings
like a modern bird.
4. One of the 'dino-bird' fossils found in China in the 1990s turned
out to be a fake, and therefore *all* fossils showing characters of
dinosaurs are birds must be a fake.
5. You are only claiming it's transitional because you are a rabid
atheist intent on undermining True Christianity (TM) and it supports
your evilutionist faith.

That all depends on your definition of "transitional". The true purpose
of this challenge is to probe Tony's definition. Now, I will agree that
by your definition we are unable to identify any transitional fossils,
since we can't determine ancestry. It's impossible to distinguish an
ancestor from the ancestor's cousin, whether at the individual or
species level. And that's why to me, "transitional" doesn't imply direct
ancestry, merely an intermediate condition that shows us what the
ancestor was like. Given the paucity of theropod fossils relative to
their true historical diversity, we are unlikely to have found any
particular ancestor, and perhaps any ancestors at all. Nevertheless, we
have many transitional fossils.
Can he use Ray Martinez' dictionary to answer that?
Ooh, I like that game. Here's more:
Pope John Paul was misintepreted as accepting evolution...no wait...he
really did accept it but was "bullied" into it...no wait...
"transitional fossils", or more recently transitional forms, simply
represent fossils whose characteristics are a mix between one kind of
animal and another. They suggest an evolutionary association but not
necessarily one of direct ancestry, which is of course impossible to
prove from the fossil record alone.
Forrest has already taken the challenge and like Elsberry offered
scientific reports for which he didn't read beyond the abstract. And
likewise Forrest was terribly embarassed. Need links to relive this

Yet another lie.
Yes, but it needn't be ancestral to any currently living species.
Archaeopteryx is considered to be transitional in the sense that it
marks a stage in the transition from non-flying theropod dinosaurs to
modern birds, not that it is an ancestor of the latter.
>

Cladistic analysis shows that it was an evolutionary dead-end. Most
likely, at least according to one study (that I read about maybe 10
years ago), it is three nodes away from the ancestor of modern birds.
But since we can learn a lot from the cousins of the ancestors in a
"transitional radiation," and because it has a host of the traits of
the ancestor of modern birds, it is considered to be transitional.
The actual

Not only is that considered to be likely based simply on the odds, the
evidence shows that this is so.
Of course, it would make no sense to recognize that Archaeopteryx has
been shown to have branched off from the ancestor of modern birds
without also recognizing the fact that the same sort of evidence
demonstrates that it is indeed closely related to a species of an
early in the stage of bird evolution.

Cladistic analysis could show that a specimen has no obvious traits
showing it to branch off to a dead end, but it couldn't really
demonstrate that we had the exact ancestral species (especially not
because the bones of what might be today considered different species
might not reveal any meaningful deviations at all). However, we learn
a lot about evolution from "cousins," both those living and those
representing extinct lines.

Excellent. Harshman has begun the New Transitional Fossil Challenge
Since we all wish to see evidence of neoDarwinism's most contentious
claim----that is, we wish to see evidence of gradual, successive,
progressive development of a structure that did not exist in
predecessor populations. The theory predicts that such gradual,
successive, progressive changes must have been ubiquitous to explain
all of biological diversity from a self replicating entity.
So in order to discuss this Harshman has to identify what structure of
the Archaeopteryx did not exist in predecessor populations, is in a
non mature state and is progressing towards maturity. Otherwise the
Archaeopteryx is nonthing more than an interesting mosaic with fully
formed, mature structures. Such mossaics exist in the living world.

The question is: How did the fossil record capture the fine
gradations of the EXISTING foram shell in Elsberry's "proof" over the
space of 15 million years but capture not a single NOVEL structure
developing to maturity where it did not exist in predecessor
populations? The foram shell existed in the starting population under
examination and remained a foram shell at the end of 15 million years.
Darwin knew the fossil record was damning in 1859, Gould knew it was
damning 1973, and everyone knows it is still damning today.
Evolutionists string together end nodes in the fossil record and
merely "conceive" of a lineal connection. There is no genuine,
observable connection.
You seem to be confusing me with someone else.

...which is just the sort of drivel creationists produce when asked
why Archaeopteyx is not a transitional. Thank you for confirming that
you also consider it to be drivel.
Now, how about explaining to us in non-drivel why any rational human

you run away again like the moral and intellectual coward you have

Can you please explain what you mean by "maturity"? Because it sounds
like a fundamental misunderstanding of evolutionary biology; perhaps
you imagine creatures with some sort of formless bump wondering when
an arm might appear?
Every species, by virtue of being alive and reproducing, has "parts
that work". Those features are indeed mature, for that creature. Is a
fin a "mature" appendage, or is it an immature leg? Is a paw mature,
or is it an immature hand, hoof, or in the case of bats, wing?
In short, mature structures, if such a term were to mean anything,
generally evolve from other mature (i.e. functional) structures.

"Evidence confirming an observation is

OK. I would say that the wing itself is such a structure. It's clearly
partly formed. It has flight feathers, and therefore is a wing. Yet it's
pretty much identical to any other theropod forelimb, except for being a
bit longer than most, and it lacks a great many of the important
features of a real bird's wing: there is no carpometacarpus, merely
unfused bones. Similarly, the planalges are unfused. There is no allula.
There is no triosseal canal, and therefore the coracoideus muscles would
be unable to power the upstroke as in living birds. This is clearly a
primitive and incomplete wing.
And of course we have a fine series of fossils showing the gradual
development of all these structures, including even the feathers, which
I would be happy to explain to you.

Actually, you are confused. Darwin liked to raise objections for the
purpose of disposing of them, which he did handily immediately
thereafter. Gould, of course, agreed that transitional forms were
plentiful in the fossil record. Even you should be able to find a quote
to that effect.

I think you are confused about what "observable" means.
I love this paragraph. It encapsulates so many misunderstanding in
such a small space that it's truly a work of art.
It's hard to know where to start.
1. You imagine that evolution has a goal, specifically the goal of
producing the set of species of living things that now exist on the
earth.
2. You think that this particular brief moment in geological time is
special and, by chance, happens to hold in it the long sought goal of
biological evolution.
3. You think that plants and animals living at other times must look
"immature" or less than "fully formed" if evolution is correct.
4. You fail to recognize that any currently living species may well be
"immature" or "not fully formed" if measured against its descendants a
few million years hence.
5. You think that evolution progresses towards goals.
6. You imagine that the theory of evolution predicts that the fossil
record will be full of animals with functionless, immature "not yet
wings" or eyeballs which have not yet developed retinas, or some such
fantasies.
You are generally prolix with words, so that there's relatively little
substance per word, but you've outdone yourself here in the density of
errors.

Well, they at least might look different, and lack some features of
modern ones.

I'm sure some of them are, but that doesn't help us find the intermediates.

Of course Tony thinks that evolution doesn't happen at all. What you're
talking about here is Tony's caricature of what he thinks we think.

Now, be fair. He hasn't yet demanded that intermediates be functionless.
If he's going that route, let him do it himself.

And let's note that Tony has not so far addressed the challenge at all.
He's playing for time, perhaps. The challenge was to show why
Archaeopteryx isn't transitional, and he has attempted to turn the
tables with a counter-challenge for me to show why it is. Of course I've
obliged him anyway.
Translation: I can't answer the question so I'll just lie and throw

Ring species then give contemporary evidence of transitions between
species.
Wikipedia has an article on ring species at http://en.wikipedia.org/wiki/Ring_species.
Fundamentally with ring species you have something like:
Population A can mate with population B.
Population B can mate with population C.
Population C can mate with population D.
But Population A cannot mate with population D.
Therefore populations B and C are partway between populations A and D.
The Wikipedia article goes into some detail about populations of
gulls. There are other examples.
Tony?
It was also my understanding that they are; it's even in the
t.o FAQ:
http://www.talkorigins.org/faqs/comdesc/section5.html
From the section "Prediction 5.5: Stages of Speciation":
"Another example of a ring species is the gull genus Larus.
L. argentatus and L. fuscus were originally identified as
distinct species in England. However, there is a continuous
ring of Larus hybrids extending to the east and west all the
way round the North Pole. Only in England are they incapable
of interbreeding."
Can you give a bit more detail about your objection to this?
Thanks.

complex is not a ring species. Proceedings of the Royal Society of

Hey, I can play that drivel game too !
7. Because dinosaurs and modern birds lived at the same time, and, at
some point maited to produce a bizarre hybid, the Archaeoptery bird.
Therefore the Archaeopteryx is not a true transitional, just a mere
hybrid, just like the well-know crocoduck.
What do I win ?
Key points:
1. Ring species do exist evenif these gulls are not an example.
2. The existence of ring species would demonstrate the existence of
transitional species since the challenge given is this one:

The intermediates between the ends of ring species are partway
"between one species and another". Therefore they meet this
definition.
A designer crocoduck handbag of course.
That's why I said "Fortunately so", in response to "There are other
examples". Snipping context leads to needless repetition.
The Ensatina complex is a true ring species, and the Phylloscopus
complex probably is.

Tony - I believe that's who 'troll' is - was asked to provide a

definition that was provided.
By that definition, transitionals exist, as demonstrated by ring
species.
Q.E.D.
Thanks! For others interested in this there's a pdf
available:
http://rspb.royalsocietypublishing.org/content/271/1542/893.full.pdf+html
If I'm reading this correctly, it looks as though while the
gulls aren't a classic ring species yet, they may become one
in the future. From the synopsis:
"Contrary to the ring-species model, we find no genetic
evidence for a closure of the circumpolar ring through
colonization of Europe by North American herring gulls.
However, closure of the ring in the opposite direction may
be imminent, with lesser black-backed gulls about to
colonize North America."
....and from the text:
"It will be interesting to see whether graellsii will turn
out to be reproductively isolated from North American
smithsonianus. If so, the circumpolar ring of interbreeding
taxa might yet close to form a classic ring species, not by
an invasion of herring gulls from North America to Europe as
postulated earlier (Geyr von Schweppenburg 1938; Mayr 1942),
but by expansion of lesser black-backed gulls in the
opposite direction."
Do you agree with this interpretation?
>Oddly enough, the Wikipedia article cites that paper but doesn't seem to

Or maybe the author was anticipating the closure of the
ring; if so it should have been noted, both in the Wiki
article and in the t.o FAQ.
Anyway, thanks again.
There is no reason to believe that troll is Tony.
It doesn't seem to be an interpretation. It's a hypothesis about what
might happen. But sure; what's not to agree with?

There is no way to know that it is a transitional species because
there is no way to demonstrate a reproductive link with another
species. It is called a transitional species because paleontologists
use it to make a transition from dinosaurs to birds in the model of
evolution. But scientific models are not natural reality and they do
not reflect what really happened in natural history.
Could you define "transitional fossil" for me?
And you seem to be saying that science is not a valid method of arriving
at knowledge of the world. Is that actually your claim?
I'd rather be a "dishonest creationist" than an arch-hypocrite calling

Yes, if Archaeopteryx never speciated then it was not transitional
but it would still be intermediate between reptile and bird.

On the other hand if one looks at all the archeopteryx's specimens:
1. it has perching feet,
2. possessed the basic pattern and proportions of the avian wing with
modern-like feathers; the primary fearthers of non flying birds are
distinctly different. there is little reason to suppose that the
Archeopteryx was not capable of and engaged in powered flight.
3. a robust furcula,
4. its cranium was essentially avian in all important aspects (which
might imply the possession of an avian nervous system and circulatory
system).
5. the quadrate of the Eichastatt specimen of the Archeopteryx was
double-headed and thus similar in condition to that of the modern
bird.
6. it has been asserted that Archaeopteryx shares 21 specialized
characters with coelurosaurian dinosaurs. Research on various
anatomical features of Archaeopteryx in the last ten years or so,
however, has shown, in every case, that the characteristic in question
is bird-like, not reptile-like.
7. it has been reasonably established that neither the teeth nor the
ankle of Archaeopteryx could have been derived from theropod
dinosaurs—the teeth being those typical of other (presumably later)
toothed birds, and the ankle bones showing no homology with those of
dinosaurs.
8. the pubis of Archaeopteryx was oriented in a bird-like position.
9. recent examinations of the ear region of Archaeopteryx shows,
contrary to previous studies, that this region is very similar to the
otic region of modern birds.
10. no one hypothesizes due to recent discoveries that the
Archeopteryx is the predecessor of any modern birds. As such the
absence of the alula is irrelevent to the issue of neoDarwinian
transformism. Furthermore the alula is not necessary for flight and
is important depending upon the size and camber of the wing.
11. there have been discoveries of fossil birds which predate the
Archeopteryx
>And of course we have a fine series of fossils showing the gradual

As I point out above there is at least as much evidence that the
Archeopteryx is a fully-formed, mature bird capable of fully powered
flight with not the slightest hint of a structure in some stage of
development.
Yet if Darwin's theory is correct we should see more structures in the
fossil record in varying stages of development than mature ones. This
is why Darwin placed little importance in the "species"----they were
rarely fixed. He expected to see a significant number of developing
nascent structures and overlap between "adjacent" species along the
continuum of evolutionary transformation. Yet we see absolutely no
unambigous examples of this.

Notice that Harshman makes light of this significant problem. Minor
changes of EXISTING structures abounds in both the living AND the
fossil world. Yet there is not a single example of an unambiguous
nascent structure or its develpment to maturity in either the living
or the fossil one.

Darwin was honest enough to admit that the absence of genuine
transitional forms was a significant problem for his theory. And
while he did give good reasons why the fossil record would never be
completely adequate, he under no circumstances explained away their
absence. He fully expected the discovery of nascent structures in
various stages of development as time marched on. No such structures
have ever materialized. NEVER. NEVER. Darwin admitted that this
was a significant problem.
Gould was an admitted atheist and he likewise never produced any
genuine evidence of neoDarwinian transformism. He likewise took fully
formed mature forms and strung them together in a conceived sequence.
He spent from 1973 on trying to explain stasis and disputing Darwin's
gradualism.

One finds that you have taken some nonsense of some creationist web
site, none of which is relevant to the question of whether Archaeopteryx
is a transitional fossil. You list some derived characters, but that
would be expected in a transitional form, in addition to the primitive
and intermediate characters I mentioned, none of which you have even
attempted to refute.

Sort of. Not, however, the sort that is meant when talking about

True.

As did many other prior theropods. A furcula isn't a bird
characteristic, just as feathers are not.

Not sure what you mean by either of those. But there were features of
the cranium that are more like birds than like most theropods. Most of
these features are however shared with troodonts.

Some modern birds. The character is variable. Most neognaths have it,
but paleognaths lack it. And oviraptoriosaurs and some crocodylomorphs
have it too.

I'm afraid you're going to have to provide more detail on that one. I

Oh dear. You've been paying attention to Alan Feduccia. Neither of these
is true. And in fact Feduccia has reversed his position on the ankle. He
was previously claiming that bird ankles are not homologous to
dromaeosaur ankles, but now he thinks that dromaeosaurs are birds.

Of course nobody hypothesizes that Archaeopteryx is the ancestor of
modern birds. It's impossible to show that any species is ancestral to
any others. What the alula has to do with that is beyond me.

If Archaeopteryx is fully formed, why does it have all those primitive
characters that I mentioned? Why is the wing not a structure in some
stage of development, since it lacks many of the features of modern
birds? Are you saying that because Archaeopteryx could fly, its wings
were therefore fully formed? If so, then all I have to do is bring up,
say, Sinosauropteryx, which couldn't fly. It seems that you have a
Catch-22 for me here. If an animal can fly, you say its wings are fully
formed. If it can't, you will just deny they are wings.

That's exactly what Archaeopteryx is. It has a partially formed wing.
You haven't even addressed the wing; you've just tried to distract
attention by talking about some other parts of the body.

How can we recognize a nascent structure? I contend that Archaeopteryx
has nascent wings, since it lacks several features shared by all modern
birds.

But there are many nascent structures in the fossil record. Darwin was
right. Even if you say "never" in all caps; even if you say it more than
once. I have mentioned one. There seems no reason to mention another
until we have settled this one.

Oddly enough, Gould thought he had such genuine evidence. He thought

Thanks. I'm afraid I can't return the compliment, since your attempt was
pathetic. Now the way we observe these connections is that they display
a very nice nested hierarchy, for which the only reasonable explanation
is a branching tree of descent. You have another explanation,
presumably, but you have never bothered to provide it.

I held my nose and waded through your cite. IIUC it makes the point
there's no evidence Archaeopteryx is ancestral to all birds and so it
isn't a transitional fossil. This is the same wrong-headed comic-book
argument made against all transistional forms. Possible ancestry has
nothing to with whether fossils display transitional features and so
properly qualify as transitional forms.
Not surprisingly, the TO archives include a pretty good article about
Archaeopteryx and the questions it raises:
http://www.talkorigins.org/faqs/archaeopteryx/info.html
Rather than focus exclusively on avian features, Chris Nedin
reasonably identified both avian and theropod features. Perhaps
surprisingly, Archaeopteryx is morphologically closer to theropods
than to modern birds. IIRC I read where Huxley said if it wasn't for
the feather impressions, he likely wouldn't have given it a second
look. Nevertheless, its asymmetric wing feathers and flat sternum are
good evidence that Archaeopteryx was a weak flier.
A nice paraphrase.

Until you can show how the transition occurred (cause) the appearance
(effect) is not real, but an illusion. We don't see it. We see each
species reflecting ID (supernatural agency).
In your debates with Kleinman I noticed that your entire case for the
cause of human evolution came down to a one word assertion
"drift." (In other words it all happened by chance and luck.) Neither
the founder of drift theory or any prominent evolutionist of the 20th
century would say such a ridiculous thing. Drift was and is not
offered to challenge or replace Darwinian selection. Your assertion
tells us that you are ignorant of historical scientific context.
Therefore your view concerning cause of human evolution is subjective,
non-mainstream and un-supportable.
Ray
Ray, as has been explained to you over and over, the cause has already
been shown. It's the natural process called "evolution".
> We don't see it. We see each

You don't "see" it because you refuse to look, as you admitted yourself.
You don't see each "species reflecting ID" because you don't know
what does, or does not reflect "ID", which you idiosyncratically define
as "supernatural agency". You are making an assumption that order
and symmetry are only produced by "supernatural agency", when there are
many counter examples.
Also, Ray, you didn't make an attempt to answer this either.

Another thing Ray has misunderstood. Obviously John's entire case
doesn't depend on the process of genetic drift.

There is an element of chance in evolution, but the process itself is
not mere chance.

No one claims it was. Drift is part of the mechanism of evolution, not
a replacement for Darwin's mechanism.

Not quite. Drift (neutral evolution) is clearly responsible for the
great majority of differences between the human and chimp genomes. But
of course the interesting and important ones are the comparatively few
exceptions. No biologist that I know of would contest this.
You are as ignorant of comparative genomics as you are of the history of
biology and, come to think of it, just about everything else.

I take it back; therapy is only valuable for those who
desire to be helped.
Your only response to a specific charge of ignorance is to claim that
your accuser is generally ignorant?
John, the ToE remains Darwinian; your causation claims are non-
Darwinian. You are ignorant of everything worked for and accomplished
by Darwin's successors. You really need to log-off and read what
evolutionary authorities have published this year and every year
preceding going back to 1950. Your thoughtless causation claims are,
like I said, subjective, non-mainstream and un-supportable.
Accomplished Darwinists like Dawkins, Gould and Mayr exist within an
established foundation and framework (Darwin's). You may have skimmed
through Gould 2002 but you obviously haven't understood anything he
has said. The entire book carefully documents the three-fold claim
made by Darwinian selection; how each claim was verified; and how each
claim defeated all falsification attempts up until c.2000. If you
understood this history you wouldn't be asserting drift alone as
causing human evolution. What makes your particular brand of ignorance
so appalling is the fact that you don't even see the need to exist
within an established foundation and framework. Again, your drift
claim in behalf of human evolution is without foundation and
structure.

I see your problem here. You are confused. I made no such assertion. I
was talking about the genome. 3 billion bases. You may have heard that
about 95% of the genome is "junk DNA". Junk DNA evolves neutrally, i.e.
through drift alone. Large parts of that non-junk 5% also evolve
neutrally. So like I said, drift is clearly responsible for the great
majority of differences between the human and chimp genomes. But of
course the interesting and important ones are the comparatively few
exceptions. This is not just my story. Any biologist would tell you the
same.

Since you don't even understand my claim, I doubt your ability to put it
in historical context.
Where there is dispute is to what degree the morphological and
behavioural differences between humans and chimpanzees are the result of
adaptive change, and to what degree they are the result of drift.

"The neutral theory claims that the great majority of evolutionary
changes at the molecular (DNA) level are caused not by Darwinian

For evolution on the _molecular_ level, nothing John has said seems
particularly controversial Some neutralists push that approach so far
(especially when it gets beyond the molecular level) that they might
be called non-mainstream (but by no means "un-supportable", their
position is taken very serious even by those who ultimately reject it,

Ray, "Darwinian" evolution still involves mechanisms that Darwin

didn't know about it, because he didn't know about genetics.

John, I'm sure is quite a bit more educated on matters of evolutionary
theory than you are, Ray. You also should remember that
"authorities" aren't what counts in science. It's evidence.

Ray, can you cite any mainstream scientific position about evolution
that does not mention drift as one of the mechanisms of evolution?
You are making yourself look even sillier than usual.
> Accomplished Darwinists like Dawkins, Gould and Mayr exist within an
> established foundation and framework (Darwin's).
And every one of them acknowledged that drift was part of the
mechanism of evolution.
Gould says:
"Populations are finite in size, and the isolated populations that
form the first step in the speciation process are often founded by a
very small number of individuals. As a result of this restriction in
population size, frequencies of allele change by genetic drift, a kind
of random genetic sampling error.
From "The Spandrels of San Marco" The Richness of Life, the Essential
Stephen Jay Gould P 433.
Dawkins says: (Dawkins terms it "Neutral Theory")
"When the neutral theory of molecular evolution was first proposed
by, among others, the great Japanese geneticist Motoo Kimura, it was
controversial. Some version of it is now widely accepted and, without
going into the detailed evidence here, I am going to accept it in this
book. Since I have a reputation as an arch-“adaptationist” (allegedly
obsessed with natural selection as the major or even the only driving
force of evolution) you can have some confidence that if even I
support the neutral theory it is unlikely that many other biologists
will oppose it!"
The Greatest Show on Earth (2009, pages 332 and 333).
Mayr says about drift (nearly 60 years ago!)
"For such a striking dissimilarity of peripherally isolated
populations two reasons are usually cited: difference of physical and
biotic environments, or genetic drift. It seems to me that neither
of these factors nor a combination of the two can provide a full
explanation, even though both may be involved.
Note too that Dawkins, Gould, and Mayr are only three, out of
thousands of biologists who acknowledge genetic drift.

another massive irony moment..... Gould's book isn't nearly as

Odd then that you'd make the silly claim that natural selection

John didn't say that drift alone caused human evolution. Where do you

According to Gould (2002) Kimura told him in a face to face
conversation that his theory exists within the Darwinian framework. I
doubt you have the ability to understand the preceding sentence in its
entirety.

How does that negate the fact that Kimura, Gould, Mayr, and Dawkins
all accept netural drift as a mechanism of evolution?
No one is saying that natural selection is not a mechanism of
evolution, and John never claimed that drift was the only mechanism
accounting for the differences between humans and chimps. Those
accusations are entirely your own misunderstanding.

It's very clear, Ray, that you've made a very large, very embarassing
mistake. Why not just admit you were wrong?

I know exactly what you said to Kleinman ((paraphrase): drift caused
human evolution). Your input here is long-winded repetition plus an
invisible asterisk.
Are we or are we not the products of Darwinian evolution? Any
mainstream biologist will answer in the affirmative.

Evasion.
If you knew what you were talking about you would have answered the
charge and placed your drift claim (= Materialism) in historical
scientific context. Kimura, by his own admissions, does not exist
outside of Darwin, but within. You did not and have not accounted for
this fact. In fact, in a matter of factly tone, you told Kleinman
that drift is responsible for all of human evolution.

Projecting your Oedipus-complex again?

One doesn't need to be a "Mommy" for one to realize that you are
wrong. Your best bet is to admit you are wrong, and slink off in
disgrace again.
