First - it should NOT be a dead horse, as there are some very
important lessons that should be learned from the whole issue.
Second, the Peppered Moth story is STILL being put before the public
by at least one prominent evolutionary scientist. It obviously is
NOT a dead horse for him!
According to Professor Steve Jones of University College, London:
"Evolution's best evidence is from a revolution; the Industrial
Revolution that polluted much of England. The nation's moths turned
black as birds ate those whose genes made them conspicuous against
sooty trees. With smoke control, the story worked in reverse, and now
the black moths are down to a fraction of what they once were."
Daily Telegraph, Feb 10, 1999, page 16.

What do you mean by saying that the moths "support evolution"? There
are certainly natural variations taking place - but variation is
common to creationary and evolutionary theories. Why should you pick
out "evolution" and not "creation"?
What do you mean by saying that the moths "still support ... natural
selection in particular"? What are the selective forces? [hint: we
have no idea! - is that a disallowed argument from ignorance?] None
of Kettlewell's reports of birds selectively eating moths carry any
weight. What is the rational basis for saying that the moths give us
any knowledge of natural selective forces?

Evolutionary scientists ARE permitted to make mistakes! Furthermore,
I expect scientists (like everyone else) to learn from their
mistakes. Dawkins comment suggests to me that he has not learned
from this mistake from the past.

Kettlewell announced his findings to the world with a fanfare: here
is "Darwin's missing evidence". The experiments have remained as
the ONLY good example of known forces of natural selection affecting
the genetic makeup of a breeding population.
Yes, there are over a hundred other examples of "natural selection" -
but in no case do we have the same clear link between identifiable
selection forces and the genetic make-up of organisms. That is why
Steve Jones described the Peppered Moth story as "Evolution's best

No. Dawkins appears to bite his tongue and count to 19 when such
impudence presents itself!
