Re: RFEP & IDHoward, I wish you would turn off the HTML.
Also I hope a Real Biologist will join in here at
I am not sure if this is the right conclusion, for the
1) Hunter never mentions the disagreement. There
is in fact disagreement between "neutralists" and
"selectionists"; it is a disagreement regarding the
relative significance of various processes. However
virtually ALL AGREE that ALL the processes occur.
So in that sense, there is no disagreement. Although
what may happen is disagreement over what's going
on in a particular case. But you probably knew that.
So whether there is a disagreement in the case he
cites would have to be researched. He's stating
there is none, that "evolutionists" jump to the
conclusion of vestigial or neutral causation.
Note, here, the profoundly different character of
a "vestigial" thing and the product of "neutral"
evolution. A vestigial thing is presumed to have
had a function sometime in the past that it no longer
performs. A neutral thing performs no function and
never has. This stuff doesn't pass the smell test
to me because it just seems to be confused and
conflating things that don't really have anything to
do with one another. In other words, I just don't
get the impression he knows what he's talking about.
2) You are partly correct in that he appears to be
taking a side, that is, the selectionist side. He's just
positing a mechanism other than natural selection,
the Intelligent Designer. (Well and good, find this
Designer and it will be enshrined in evolutionary
biology textbooks along with Kimura's neutral theory.
Allan Orr makes a similar point in his review of
Darwin's Black Box)
3) Why doesn't he mention Ohta's nearly-neutral
theory as an example of an alternative view regarding
"neutral" evolution. The statement that "evolutionists"
immediately jump to the side of non-functionality is not
universally true! I am beginning to think that the
classic accounting answer, "It Depends" is quite
relevant as well in biology. The problem with ID'rs
is they don't like that answer, and think that answer
points to some kind of weakness in biology.
4) Note as well, what I think is a perverse rhetorical
strategy. The sheer volume of variation is noteworthy,
as I previously posted. It is really hard to be aware of
this volume of variation and not come to the conclusion
that some of it is random, or better yet, call it
unexplained, "noise". Then as measurement techniques
or whatever get better you may identify other causes.
But to say it is unfair for biologists not to be actively
looking for function in all these cases is unreasonable.
Why does he say there are many varieties but doesn't
give the number that have been identified? Is it
because it would make his case that the numerous
variations of hemoglobin are like the 86 so-called
vestigial organs (which are not basically repeats of each
other, and so are not analagous to the hemoglobin
situation) look, well, a little silly?
This critique of evolution is novel in the sense that
virtually everything that's been done so far is a
critique of Dawkins. Behe says now he is going
to research gene duplication so that is a little different,
but I don't think he's outlined what he plans to do.
I am thinking that if you haven't read Ridley's
_evolution_, which is a collection of essays and
extracts from books organized by theme, eg,
adaptation, neutral evolution, etc, you might
wish to read that.

Thanks for the instructive comments. It now looks to me as if Hunter, in the
excerpt provided by Jack Haas, is taking an active disagreement within
biology and crediting ID with being the insightful critic of evolutionary
biology from the outside with a novel paradigm (look for function, based on
knowing how an unknown Intelligent Designer would have done things) not
generally found within biology itself. Do I have it right?
