"Australian geneticist Associate Professor Philip Batterham from the University of Melbourne said the research showed humanity was far more closely related that previously thought and that race was a cultural phenomenon.
Once again, political correctness corrupts science. Race is unquestionably based on genetics. Note that any time there is marriage between Negroid and Caucasoid, Mongoloid and Caucasoid, and any other combination, that the resulting offspring DO follow Mendel's laws of genetics.
How's that?
Race IS a cultural phenomena. Race is all about politics. Living in the US you would notice this.
The differences we create in terms of race are purely man-made. Do we consider brown horses as a different "race" than spotted horses? The horses certainly see no difference.
Hair color and eye color are also genetic. But we don't separate brunettes, blondes and red-heads into separate "races". But we do separate on the basis of how flat noses are, round eyes are and by skin color.
