- Chris Colby writes: "The moth example is, by definition,
- evolution. There are few studies that document it in as clear cut
- a manner as Kettlewell's work. You don't understand evolution."
- ...
-
- "Please explain how natural selection is a creative process.
- Selection is differential reproductive success of classes of pre-
- existing genetic variants. This (often, but not always) results
- in a change in frequency of genetic variants in a population.
- Where is the creativity? You don't understand natural selection."
- [End of quote.]
-
- That natural selection is not a "creative process" is exactly my
- point. That is why it does not explain the fantastic growth in
- the complexity of the genetic program needed to govern the
- biological processes of plants and animals. If the peppered moth
- example is "by definition, evolution," then evolution is not a
- very important subject. The important question is how relatively
- simple forms like bacteria become far more complex forms like
- plants and animals. If the peppered moth example explains this
- also "by definition," then what you call evolutionary science is
- nothing more impressive than the manipulation of definitions.
-
- BTW, I was teaching a seminar yesterday, with a critique of the TV
- version of The Blind Watchmaker. All about the vast *creative*
- power of natural selection, quite a contrast with the Colby
- doctrine. And yes, I know all about cumulative selection. See
- my summary of the doctrine of creative natural selection at the
- BEGINNING of Chapter Two of Darwin on Trial: "As the process of
- differential survival continues, the trait eventually spreads
- throughout the species, and it may become the basis for further
- *cumulative* improvements in succeeding generations. Given
- enough time, and *sufficient mutations of the right sort,*
- enormously complex organs and patterns of adaptive behavior can
- eventually be produced in tiny *cumulative* steps, without the
- assistance of any pre-existing intelligence." P. 17
-
- Of course, to me that's a hypothesis, not a dogma to be
- propounded. And the problems with the mutation component are the
- subject of Chapter 3. You seem determined to obscure the issues
- in word games. No wonder.
