We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Charles Murray: evolution continued long after humans left Africa
Sure, but ..
Charles Murray: Since the decoding of the genome, it has been securely established that race is not a social construct
Um, no; which is why so many scientists discount Murray's work. If it was securely established, it wouldn't be rejected by the majority of anthropologists.
Edgar & Hunley, Race reconciled?: How biological anthropologists view human variation, American Journal of Physical Anthropology 2009.
As for specifics, human variation is much more a continuum than a lumping of groups. Indeed, the number of races is statistically arbitrary.
While there are certainly genetic differences in human populations, any notion of race that lumps all blacks together, groups Khoisan with Bantus, or South Asians with Saan, is not based on genetics, but are social constructs.
