Hmm. If I ever get subscribed to LFS-chat I would take this there, but
you are wrong.
evolution happens through natural selection. that is the process wherby
things with a disadvantage die, and things with advantages live.
the method the things reproduce by is irrelevant to that.
the only difference the reproductive method might make would be to
perhaps acclerate the mutation rate, but I dont have numbers for that.
the point is that asexual reproduction does NOT result in a series of
clones, which is effectively what the original poster suggested.
