What do you mean by evolution? Animals absolutely change. The question is to what degree. For instance, should one insist that all life descended from a single cell? How about solely via random mutation and recombination, and natural selection?
Well I seemed to have been involved in two arguments. One is evolution doesn't exist at all. The second one is what we think of as evolution is really a designer making changes over time. Am I phrasing these properly? If so... then I have been arguing against both.
should one insist that all life descended from a single cell?
Well...is that so hard to believe given we all individually start out conceived as a single cell when a sperm and egg meet?
