What about it?

I did find that they have added a fourth that I was never taught and that is Australoid.

This is all from Anthropology class, as I recall, which is why I placed the term "race" in quotes. There does appear to be some very minor genetic differences between the races, which is probably to do with mate selection in a given area.
