As you may have discovered on that message board, there are even comments re:Caucasoids being thrown into the mix. That has pretty much been established out in western China. Interesting to see if it also shows in the eastern or nor eastern provinces.
The Malgal/Mohe/Mo-Ho look like a particularly elusive bunch. Records get written by the winners and they look like they were often conquered and absorbed.
Looks like a lot of Caucasians in the mix. I've stated before that " I would be the least suprised person in the world if the First Emperor of China was a tall red-headed guy."
