A working model on the peopling of Eurasia

Image
This post will deal with the peopling of Eurasia by modern humans and their subsequent Paleolithic movements and divergence patterns. – Part I of our "in development" series on the question to ' who we are and where we came from ': Paleolithic to Epipaleolithic period. Overview Modern humans have a "recent African" origin, having evolved within the African continent, and diversified there; one of those branches became isolated in Northeast Africa and would subsequently became ancestral to all modern living 'non-African populations': Eurasians . This branch would carry out the "Out of Africa" migration, – but they were not the first humans to leave Africa; they were preceded by earlier extinct waves of modern humans, possibly distantly related to those of the later main OoA wave – as well as deeper archaic groups which would have become ancestral to the Neanderthals or Denisovans. Shortly after the Out of Africa migration of modern humans (c...

Working model on East Eurasian lineages

Image
This short post will summarize the archaeogenetic data on ancient and modern East Eurasian populations and their origins. – A compact overview on the 'East Eurasian' branch of humanity, also occasionally known as "eastern non-Africans" (ENA). Overview After the Out of Africa exit (c. 60kya), Proto-Eurasians settled in northern Mesopotamia and on the Persian plateau, which acted as 'population Hub'. – It was in this region where they received archaic Neanderthal input at c. 55–50kya. (Archaic introgression continued until around 45kya for regional groups, and in the case of Denisovan contact in the Asia-Pacific region, well to 40kya). – An earlier diverged branch may have remained on the Arab peninsula and or Northeast Africa: "Basal Eurasians" who did not have received any significant archaic admixture. [1] [2] [3] The major split within Eurasians happened around 50kya within the 'population Hub', resulting in the formation of the ancient Wes...
