Quote:...and then, if it is unsuccessful, start over...
I think this is the point to focus on, this is the biggest flaw in it. As far as I can make out, this is essentially a mathematical version of the "half an eye is useless" argument: it claims that any unsuccessful mutations suddenly cancel out any previous ones and we start from useless noise again.
I'm also looking into the second part of his doubts - the "where's the man/monkey fossils" part. I know that we don't know for sure which species was the common ancestor of chimpanzees and humans, but that it was some time before Australopithecus (I believe there was some possibility that maybe Chimpanzees evolved from them, but this isn't widely held now?).....but what I'm wondering is, do we have a name for the most recent known common ancestor? I mean, we're aware of species preceding mammals entirely, so there must be a 'most recent ancestor' that we can point to and say "both Chimps and Humans definitely (you know, science 'definitely') evolved from this species" even if it's not necessarily the most recent one?
