I don't quite understand what you're trying to say there Dave. Adaptation is a behavioral change, which is wholly different than a PHYSICAL change.

Deer have changed physically. For example, I'd wager that the dewclaw was, at one time, an integral part of the hoof, as opposed to our current herd, where that part of the hoof has essentially become obsolete.

Selective breeders claim to be able to grow deer with larger antlers from certain genetic bloodlines. It's a fact, evidenced by both their results, and the tens of millions of dollars spent annually in whitetail breeding and research. These guys aren't just wasting money for fun.

These species are actually changing, but in what ways?

Are we ultimately harming the species through selective breeding for a single genetic trait (large antlers)?

I would also stake the farm on it that if you compared a whitetail skeleton (or it's closest forefather)from 1 Million years ago, and compared that to a skeleton from today, they would not be identical. I'm wondering what the key differences are, and why they've become manifest.
