This is one of the stupidest things I've seen in a while. All such a finding would do to me is confirm my suspicion that yup, I'm a mongrel, like most Americans. I'm happily a Heinz-57 mix of most races on the planet. About the only thing I think I might be missing is some Asian ancestry, but wouldn't be surprised by it.

I'm not too sure the article is for real -- last year the drumbeat was, not enough African DNA, where's my African DNA, racists racists racists, along with where's my Native American DNA etc. More people are getting their minds around the idea that the family stories about Precolumbian tribal roots were actually about African roots, and that African roots can't stay that way if the white devil slavemasters you've been complaining about were studding all their slave women.

The main thing is, people don't seem to realize that they only got half of each parent's chromosomes, and since there are 23 pair, iow, not evenly divided by 2, their DNA is coming at least slightly disproportionately from two of the grandparents (one on each side, or in some families, well, heh), and that skew continues, because we really have 46 family trees. By the 6th-great-grand generation, there are 64 names, but at most (again, assuming no family crossroads on the way back to that level) only 46 managed to squirt any of their DNA through.
