Despite our recent sad conflicts here in the U.S., there really is no such thing as race.

5. just LOOK at this hot haplogroup mess

so the Chippewa are genetically basal to the Indo-Europeans, the Russians are the closest to South Asia's "Aryans," the rest of the Native Americans are in turn related to the Chippewa-Indo-European complex, the "Nordics'" closest relatives are the Balkans and then the Greeks/Anatolians/Semites, and the Aborigines are closest to the Mongols, Kazakhs, Tangut, and Athabascans ...

most telling, of course, is that it doesn't line up with the female chain of mutations (on mtDNA), so the two halves of the ladder (male-only and female-only transmission) are pretty far apart and the rungs are nicely jumbled: "race" is dead and buried, despite the initial fears about the Human Genome Project

of course there's plenty of "race realists" still infesting science and arguing that we originate from the same stellar nebula can only take you so far--you gotta bring in monogenesis and hylozoism, which are philosophical rather than scientific (the boundaries can be mushy, tho)
