Some kind of lizard turns into another kind of lizard.
Another *species* of lizard.
Can apes and humans mate? I know - lots of jokes there -
"There are some things even an ape won't do"...
but can they?
Actually, that's an open question. No one's willing to test it, for obvious ethical reasons. But whether they can or not, what's your point?
No one has a problem with adaptation - it is often quite obvious. But I have yet to see proof that humans used to be apes.
Again, drop the "proof" canard. And again, why do you keep ignoring the clear and overwhelming evidence that has been posted countless times? Why do you just keep reverting to repeating your "I haven't seen anything" over and over again? Why not actually *look* at the evidence for a change, and honestly *deal* with it? The vast majority (99+%) of biologists, familiar with the evidence, have been convinced that it is solid, and conclusively demonstrates that man and the other apes share common ancestry. There is *vast* evidence supporting that conclusion, and none to the contrary. Deal with it.
