Out of South Africa

Researchers from the University of Huddersfield, the University of Cambridge, and the University of Minho in Braga have found genetic evidence that a small group of Homo sapiens left South Africa and migrated to East Africa between 100,000 and 70,000 years ago. We know from other evidence that 60-70,000 years ago the large migrations of humans that spread around the world began from East Africa.

We know from various lines of evidence that modern humans seemed to be linked to South Africa. I reviewed some of this more extensively in a post over six years ago, but missing at the time was the connection to East Africa which has appeared to be source of the main migrations that spread around the world. The researchers believe that perhaps this relatively small group of humans might have transmitted biological and cultural traits to the humans of East Africa.

Quoting from the article:

The identification of this signal opens up the possibility that a migration of a small group of people from South Africa towards the east around 65,000 years ago transmitted aspects of their sophisticated modern human culture to people in East Africa. Those East African people were biologically little different from the South Africans—they were all modern Homo sapiens, their brains were just as advanced and they were undoubtedly cognitively ready to receive the benefits of the new ideas and upgrade. But the way it happened might not have been so very different from a modern isolated stone-age culture encountering and embracing western civilization today.

    You think there could have been an earlier wave, or waves? I’ve seen it proposed to account for Australian aboriginals, whose earliest evidence (to-date) is 65,000 y.
