Ultimately this is the sort of thing that is utterly fascinating to me, but since a) it gives me no reason that I _shouldn't_ believe it (corollary: mentions no competing viewpoints), and b) I have no expertise at all in the field, I have to assume that I shouldn't go around telling everybody that I know why Europeans are the whitest people on Earth, just yet.
The one presented fact that I'm _not_ totally solid on is, I'm not sure that prehistoric and ancient art are sufficiently solid to provide a date by which we can assume Europeans were white.
