I am not saying that one population is better than the other, but it seems very evident to me that the fact we are only classifying humanity as 'one species' or even 'one race le human race' is merely because of historical/political reasons.

There is no chance in hell an alien paleontologist would ascribe these skulls to a single species. And that doesn't even account for all the other internal physiological differences people have.

Am I really that wrong with my intuition?Am I overlooking something here?
