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 ...
The appearance of early hominins in Eurasia coincided with a reduction in the diversity of the continent's carnivore guild. It has been postulated that this was related to the Oldowan-Acheulean transition, as the development of Acheulean technology signifies a change in human ecology from a passive, scavenging role to that of more active predation.
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.
Chen et al. (2020) analyzed 2,504 African samples from all over Africa, and found archaic Neanderthal ancestry, among all tested African samples at low frequency. They also identified a European-related (West-Eurasian) ancestry segment, which seems to largely correspond with the detected Neanderthal ancestry components.
The assumption of complete replacement has been revised in the 2010s with the discovery of admixture events (introgression) of populations of H. sapiens with populations of archaic humans over the period of between roughly 100,000 and 30,000 years ago, both in Eurasia and in Sub-Saharan Africa. Neanderthal admixture, in the range of 1–4%, is ...

Around 1.8 million years ago, Homo erectus migrated out of Africa via the Levantine corridor and Horn of Africa to Eurasia. This migration has been proposed as being related to the operation of the Saharan pump, around 1.9 million years ago. [citation needed] Homo erectus dispersed throughout most of the Old World, reaching as far as Southeast ...
