"They dominate because they can run fast."
The truth of the matter is that their being dark skinned and their obvious fleetness of foot is the effect of adaptation to their ancestral environment. Nothing more, nothing less.

Really??, then why don't we see Amazon Stone Age Indians winning sprints or Aborigines or Highland Asian Stone Agers from Mindanao doing the same? I am not trying to make a political point here but I am interested in exploring the flaws in the "Culture, Environment, Geography Explains Everything" argument. Are you saying that once upon a time Caucazoid or Mongoloid race folks could have competed just as well but we became too civilized and less physically adept? If so did our environmental factors civilize us or vice versa. Nothing about this argument dovetails nicely from either side of the perspective in my view. Good or bad intentions simply do not hold up to facts or flaws.
