Among Many Peoples, Little Genomic Variety

I have a friend with slightly darker skin than me and he said people with colour prejudice are evil and I replied no, they are ignorant.


No he wouldn't have it that they were ignorant, he was adamant they were evil , so I said they were unaware of the genetic evidence some of which follows.


The more people are aware of this evidence, the more racial prejudice will be marginalized.

There is a simplicity and all-inclusiveness to the number three -- the triangle, the Holy Trinity, three peas in a pod. So it's perhaps not surprising that the Family of Man is divided that way, too.


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.
