Did you see his quotes or his studies? Human caste, come on, pathetic to not call him racist, at least!
"Harpending once stated that people of sub-Saharan ancestry do not have the same genetic propensity for "hard work" as Eurasians do. According to geneticist David Reich, "there is simply no scientific evidence to support this statement."
I can picture the tears of moral outrage streaming down your face as you wrote that.
Now, to set you straight:
1: Harpending didn't invent the Fixation Index. Credit seems to be given to the work of Cavalli-Sforza, Menozzi and Piazza (1994). Quick, go check the SPLC website and see if they are also "known supremacists".
2: Regardless of what Harpending's association is with the Fixation Index and what he thinks of the work habits of Africans, it's still in use as a measure of genetic distance. It's good science!
