I don't believe the "religious" story of "poof they you are/created with a magic wan" type of a deal though.
Agree with your premise, but I'm pretty sure 1000 is too low a number.The difference of 1, 2, or 3 generations is never enough to be different species. But, if you look at 1000 generations, the differences are vast enough that it's almost always different species.
I really regret writing about the same topic so much, however.
