There was a comment on this by Robert Wright - a totally unapolegetic sociobiologist (or as they like to be called, 'evolutionary psychologist'). He commented that people meeting people of other races is very recent. Up until a few thousand years ago, people would only meet people who lived within a few hundred miles (at most).
This meant that, for practical purposes, almost all interaction was with people of one's own race. Therefore, almost all evolutionary pressure would come from competing/cooperating with others of the same race.
The article is in Slate, but I can't find it (their search facility is mediocre, and downloads crawl sooooooo slowly........).
