I'm sorry if this is off-topic, but I think the users of this SE site would be best equipped to answer it. It's a question about the historical development of an anthropological idea.
If you are unaware, there is a list of nations in Genesis 10 descended from Noah's three sons, from where a tradition comes that the three sons when in three separate directions after the flood to repopulate the Earth. One North, one South, and one East.
The anthropological distinction of the races as being part of these three group, Caucasoid, Negroid, or Mongoloid, could be seen as North, South, and East, respectively, from the approximate location of the Ark's final resting place.
My question is did the old tradition about Noah's sons influenced the anthropological distinctions?
