OK. I don't get it.
As far as I can tell, the "daughter species" gets isolated geographically from the "parent species." Over time, members of the daughter species mutate. Eventually the cumulative effect of the variations makes it impossible for members of the daughter species to mate with members of the parent species.
So far so good?
My problem is, somewhere along the line one member of the daughter species mutated enough to become reproductively isolated from the parent species. But at the same time that creature must necessarily be reproductively isolated from the other members of the daughter species, unless an opposite sex member of the daughter species mutated comparably simultaneously.
Not only does that sort of thing not happen in nature, but they sat there for years trying to cause that to happen with fruit flies which produce new generations every few days and could not figue a way to. Kind of like saying that a time machine or a faster than light volkswagon is too complicated for man to build but, if you wait long enough, it'll just sort of come together naturally...
Don't picture a breeding population as a point along a spectrum, picture them as a cloud of dots, denser in the center and sparser on the fringes. When a daughter population is split from the group, picture that dense center splitting and gradually moving apart. For awhile the fringes are quite capable of intermixing, but as the dense centers move farther and farther apart the fringes become less and less interactive until there is nothing linking the two clouds any more.

You don't refute. You just repeat, having ignored every correction of your absurdly bad strawman model of what punk-eek doesn't say.
You don't want to be like gore3000, do you? He's the poster boy for Holy Warriors who brazen too long and can't acknowledge error or even slink away. So now, like the flying Dutchman, he's condemned to twist in the breeze, pretending he can't see requests to explain his false claims.
