Fisher's Theorem Reversed
First, a note of explanation. As we have seen in many examples, quite a few people refer to simple changes as "evolution", attempting to conflate variation with universal common ancestor evolution, as popularized by Charles Darwin. I have learned from other biblical creationists to specify those differences in terminology, so you will often see the word Darwinism on this site.
