Re: [asa] Millions of years population growth

I'm not a geneticist, but I try to keep up with what is going on. I
understand that there are control genes, such as those that time the
action of a cascade of genes that produce certain effects. A small change
in a control gene, whether in timing or in dropping or adding an effect,
would produce the kind of change labeled punctuate equilibrium. Probably
similar results can come from the incorporation of genes from outside the
genome, which has been documented.

Do you suppose that wishful thinking operates among those who don't want
evolution to be true?

Hi Jon, you wrote:

And, "Since the evidence does not support their theories, evolutionists

no evidence for this, nor any known mechanism to cause these rapid
changes. Rather it is merely wishful thinking. We need to teach our
children the difference between science and wishful thinking."

I took a course in human evolution at George Washington University and we
had a guest speaker named Williamson who published solid evidence for
punctuated equilibrium in Nature in the early 1980’s. Those of you who
have access to past issues of Nature might want to look up his article.
I’m going from memory now so please correct me anybody who can find his
article (Campbell that’s you). He did a study on mollusks in Lake
Turkana and found a few million years of stasis before and after about
5,000 to 50,000 years worth of very rapid morphological change across
phyla. I approached him after his talk and asked him if he could offer a
causal factor and he said, “Sure, draught.” I’m not sure he offered a
rationale in his article, but that’s what he told me.
