The "recent African origin of modern humans" proposes a "single origin" of Homo sapiens within Africa. Recent genetic and archeologic data suggests that Homo sapiens-subgroups originated in multiple regions of Africa, not confined to a single sub-region of origin, with the last common ancestor of all modern humans expanding from a single region ...
The genetic history of North Africa encompasses the genetic history of the people of North Africa.The most important source of gene flow to North Africa from the Neolithic Era onwards was from Western Asia, while the Sahara desert to the south and the Mediterranean Sea to the north were also important barriers to gene flow from sub-Saharan Africa and parts of Europe in prehistory.

The genetic history of Southern Africa encompasses the genetic history of the people of Southern Africa. The Sahara served as a trans-regional passageway and place of dwelling for people in Africa during various humid phases [ 1 ] [ 2 ] [ 3 ] and periods throughout the history of Africa .
The ethnic groups of Africa number in the thousands, with each ethnicity generally having their own language (or dialect of a language) and culture. The ethnolinguistic groups include various Afroasiatic , Khoisan , Niger-Congo , and Nilo-Saharan populations.
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.

"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.
[citation needed] As of 2012, the genetic analysis of human populations in Africa and Eurasia supports the concept that during the Paleolithic and Mesolithic periods, this route was more important for bi-directional human migrations between Africa and Eurasia than was the Horn of Africa. [34]
