Bab-el-Mandeb is a 30 km strait between East Africa and the Arabian Peninsula, with a small island, Perim, 3 km off the Arabian bank. The strait has a major appeal in the study of Eurasian expansion in that it brings East Africa close to Eurasia. It does not require hopping from one water body to the next across the North African desert.
The finding that "Mitochondrial Eve" was relatively recent and African seemed to give the upper hand to the proponents of the Out of Africa hypothesis.But in 2002, Alan Templeton published a genetic analysis involving other loci in the genome as well, and this showed that some variants that are present in modern populations existed already in Asia hundreds of thousands of years ago. [31]
"Recent African origin", or Out of Africa II, refers to the migration of anatomically modern humans (Homo sapiens) out of Africa after their emergence at c. 300,000 to 200,000 years ago, in contrast to "Out of Africa I", which refers to the migration of archaic humans from Africa to Eurasia from before 1.8 and up to 0.5 million years ago.
Svante Pääbo, Nobel Prize laureate and one of the researchers who published the first sequence of the Neanderthal genome.. On 7 May 2010, following the genome sequencing of three Vindija Neanderthals, a draft sequence of the Neanderthal genome was published and revealed that Neanderthals shared more alleles with Eurasian populations (e.g. French, Han Chinese, and Papua New Guinean) than with ...
Researchers also probed how Neanderthal ancestry changed among the early modern humans over time. They found some genes “present at high frequency” in the early humans which they think were ...
The Neanderthal DNA found in modern human genomes has long raised questions about ancient interbreeding. New studies offer a timeline of when that occurred and when ancient humans left Africa.
Pre-Neolithic and Neolithic migration events in Africa. [15] A visual summary of the main admixture movements into and within Africa. [37] Significant Eurasian admixture is found in Northern Africa, and among specific ethnic groups of the Horn of Africa, Northern Sudan, the Sahel region, as well as among the Malagasy people of Madagascar.
An individual whose ancestry lies beyond sub-Saharan Africa may carry about 2% of Neanderthal DNA. Sub-Saharan Africans can carry Neanderthal DNA, presumably descending from modern human migration between Eurasia and Africa. [150] In all, approximately 20% of the Neanderthal genome appears to have survived in the modern human gene pool. [151]
