Humans migrated north, rather than south, in the main successful migration from Cradle of Humankind

New research suggests that European and Asian (Eurasian) peoples originated when early Africans moved north - through the region that is now Egypt - to expand into the rest of the world. The findings, published in the American Journal of Human Genetics, answer a long-standing question as to whether early humans emerged from Africa by a route via Egypt, or via Ethiopia

Tracing the Route of Modern Humans out of Africa by Using 225 Human Genome Sequences from Ethiopians and Egyptians

The predominantly African origin of all modern human populations is well established, but the route taken out of Africa is still unclear. Two alternative routes, via Egypt and Sinai or across the Bab el Mandeb strait into Arabia, have traditionally been proposed as feasible gateways ...(snip)

Distinguishing among these alternatives has been difficult. We generated 225 whole-genome sequences (225 at 8× depth, of which 8 were increased to 30×; Illumina HiSeq 2000) from six modern Northeast African populations (100 Egyptians and five Ethiopian populations each represented by 25 individuals). West Eurasian components were masked out, and the remaining African haplotypes were compared with a panel of sub-Saharan African and non-African genomes. We showed that masked Northeast African haplotypes overall were more similar to non-African haplotypes and more frequently present outside Africa than were any sets of haplotypes derived from a West African population. ... pointing to Egypt as the more likely gateway in the exodus to the rest of the world.


This makes sense. Early proto-Eurasian people could not have gotten through the Somalia pirates anyway, had they taken the Horn of Africa route.

1. Much easier to find a way across the Suez canal than to have to deal with the pirates. I agree. eom

4. They just had to pick a quiet episode between the Israelis and Palestinians

2. Maybe not all Eurasians, they didn't test Australians, Indian tribals, Melanesians

They may be from an earlier wave across the Strait of El Mandeb.

3. That was a possibility supported by Spencer Wells

wonder how his early work holds up with recent progress with the Austronesian genetics
