Uh huh, but individuals don't count in evolution, only populations.
Do you think that chimp/human mating has produced creationists? ;-)
That's true when the changes are just allele changes. It's also true when genes are inserted or copied within existing chromosomes. But somewhere along the line, chromosomes are duplicated or fused or whatever, changing the count. Otherwise, common descent is invalid.
There are (at least) two possible scenerios when this happens: one is that it happens frequently enough within a population that the "new" types find mates; the second possibility is that sometimes this just isn't an absolute barrier to reproduction.
