Abstract
Recent advances in molecular genetics allow tracing of past human migrations by markers on human mitochondrial DNA and Y-Chromosome DNA. The results show that humanity is very young compared to other species and that as a result there is very little intr-specific variation (about .1%). Further only a small portion of that .1% about 10% is distributed geographically. This means that traditional racial divisions mean almost nothing. They are confined to differences in population frequencies of certain external traits (skin color, hair texture) and susceptibility to certain diseases. Searching for racial differences on in basic human capabilities or dispositions is, therefore a fool's errand.
