So it's time we all started to emphasize our overwhelming commonality, rather than dwell on our miniscule differences.
Racism is dead, an ugly reminder of our past ignorance and immaturity as a species.
This has led some population biologists to the conclusion that not so long ago the human species was composed of a small group, perhaps 10,000 individuals, and that human populations dispersed over the Earth only recently. Most genetic variations predated that time. A s DNA sequence data become increasingly easy to accumulate, relationships among groups of people will become clearer, revealing histories of intermingling as well as periods of separation and migration.
