okay, smarty put up or shut up, where is your example of a species changing into another?? living or in fossil record.
(the horse has been debunked already)
"As I said above, find the dog with both forms of the size gene...."
as far as I know no one has mapped the genome of the dog. so you are knowingly asking for the impossible to prove a point. But it proves nothing..
If you think horse evolution has been debunked (it hasn't), I'm not going to bother trying to come up with something else.
as far as I know no one has mapped the genome of the dog.
Actually, they have. That's how they found the small-dog gene. But regardless, they've found the gene whose one form leads to large dogs and whose other form leads to small ones. If they could find dogs with each form, someone should be able to find a dog with both, if your hypothesis is correct.
