I saw this video being shared this morning on the facebook, and I wanted to ask if anyone had any reliable information for either side of this argument. I don't have a side or angle on the subject, I'm just interested in separating 'spin' from truth. Perhaps it's not meaningful to think of cultural history in the objective terms of 'race', since it is a somewhat modern concept. However this video is seriously dividing my friends - who, by the way, are not particularly knowledgeable or interested in the history of peoples of the earth or anthropology.
