"But if you know of any anthropologist who has publicly used the mass of evidence which social anthropology has accumulated, to argue that there are innate differences between different races, I'd be glad if you could tell me. I'd also be interested to see how he or she did it."

I don't think it was a social anthropologist, but I'll dig for it. Was a professor in California who argued that there WERE racial characteristics. I know he caused a stir at the time but the university had to keep him on. I'll get back to you. As a BTW, I had not meant to single out anthropologists. My apologies if you took it that way.
