"The reigning intellectual orthodoxy is that race is a 'social construct,' a cultural artifact without biological merit," writes Prof. Murray. "Since the sequencing of the human genome in 2003, what is known by geneticists has increasingly diverged from this orthodoxy, even as social scientists and the mainstream press have steadfastly ignored the new research."
"The Race FAQ" by Steve Sailer is a good place to start to unlearn race orthodoxy. Mr. Sailer's "bottom-up approach of thinking of racial groups as extended families that are partly inbred" seems more on target than that of the professors in question who follow "the traditional top down Linnaean structure in which races are conceived of more or less subspecies."
[Neat as it is, the whole "Linnaean structure," the whole damn thing, falls apart pretty quickly as pretty subjective, does it not, or is it just me?]
I have from kidhood found human biodiversity fascinating. Now, I find myself in a Sailerian extended family that includes the world's three major racial subdivisions, and I love them all.
