An article based on a recent research paper that found only little genomic variety among humans was published in today's edition of The Washington Post. Excerpts follow:

All of Earth's people, according to a new analysis of the genomes of 53 populations, fall into just three genetic groups. They are the products of the first and most important journey our species made -- the walk out of Africa about 70,000 years ago by a small fraction of ancestral Homo sapiens.
One group is the African. It contains the descendants of the original humans who emerged in East Africa about 200,000 years ago. The second is the Eurasian, encompassing the natives of Europe, the Middle East and Southwest Asia (east to about Pakistan). The third is the East Asian, the inhabitants of Asia, Japan and Southeast Asia, and -- thanks to the Bering Land Bridge and island-hopping in the South Pacific -- of the Americas and Oceania as well.
