I always understood the three subsets of
homo sapiens to be Caucasoid, Mongoloid and Negroid based upon skull shape. Never heard about the hair, though.

Apropos of nothing, I was watching an anthropology show. Learned there were three types of hominids living at one time, quite possibly all together at the same time:
homo sapiens,
Neanderthal and
Denisovan. That
Denisovan one was completely new to me. I knew
Neanderthal DNA has been found in modern humans thanks to inbreeding. But now I learn that there are population segments of
homo sapiens, based on location, that contain
Denisovan DNA, as well. The
Denisovans were from Siberia, and apparently interbred with
Neanderthal, with
Neanderthal interbreeding with
homo sapiens thus leaving behind
Denisovan DNA in the human genome. I'm waiting for them to isolate the
horrendus bardos DNA, so we can isolate those with it at birth. (Would have saved us from King Putz and his Knights of the Race Table.)
