Thanks for that tidy boiling down Ned, I got a lot from it.
I was doing some reading on creationist sites and read about the older earth creationist's Hugh Ross and his idea that large creatures periodically die out and have to be restocked by subsequent creations. To him this explains transitional forms ( horses and whales used as examples), but I could not find out what mechanism he thought brought this about. Faith's idea of continually lessening genetic variability sounds compatible with this view, as far as it goes.
And before the alarm bells ring, I believe neither... just thought that this lessening variability idea represents an appealing concept for some branches of Christian apologetics.
