I am inclined to say that I do accept the natural phenomenon of microevolution, or what we sometimes know as genetic drift. Now, I can duct for cover, as people throw rotten produce at me.  |
Yes, I've seen it first hand. It's no different than animal breeding for certain traits. Deer in the Florida Keys are whitetails, but much smaller than mainland whitetails. That's because the littler ones didn't eat as much and survived on the limited forage.
And I knew an old rancher who raised cattle in a wild part of Montana. He didn't do any selection at all, didn't try to save the weak or sick ones. After 10 generations his herd was noticeably different from standard cattle. The were definitely more agile and longer legged to handle the rough terrain.
Nothing mysterious about it. I don't like to call it "microevolution". Instead, it is just selection for traits
within a species. Either the environment does it or the breeder does it.
