What, I rebutted the argument, and then pushed back even harder. I think it was a great example of rhetorical skill.
As far as the claims that they are a subspecies. What does that mean, besides the fact that they are incredibly similar to other furry, small rodents that look incredibly alike?
Though, as far as you mentioning dogs coming from wolves. That's like saying man came from primitive man. It's a statement of the obvious. Though I really doubt that any one would be crass enough to try saying that a caveman is actually the same species, because we wouldn't be able to recognize the similarities, because thousands of years of slowly decreasing the difficulty that we have coping with our environment has made us appear very different, and have different appearances.
Not proof of interspecies evolution though, proof that we adapted to our environment (or rather our environment to us) certainly, but not evolution.
Besides, I'm having a lot of fun making an ass out of myself.
