"It'll be interesting to see how the PC crowd handles Kennewick Man, caucasian as he apparently was."
My understanding is that DNA analysis showed that Kenny was not closely related to Indians or Caucasians. He belonged to a distinct group that is no longer in existance (probably wiped out by the peace-loving redskins). He may have looked like a white guy, but that was coincidental.
There is nothing "coincidental" about genetics. Not only can it be determined if he was Causasian through genetic testing (if genetic material exists), but it can also be determined if he was Caucasian from an analysis of the remains.
Indo-Europeans?
