History of Early Human Migrations

Early human migrations are the earliest migrations and expansions of archaic and modern humans across continents beginning 2 million years ago with the out of Africa migration of Homo erectus. This initial migration was followed by other archaic humans including H. heidelbergensis which lived around 500000 years ago and was the likely ancestor of both Denisovans and Neanderthals. Within Africa Homo sapiens dispersed around the time of its speciation roughly 300000 years ago. The recent African origin paradigm suggests that the anatomically modern humans outside of Africa descend from a population of Homo sapiens migrating from East Africa roughly 70000 years ago and spreading along the southern coast of Asia and to Oceania before 50000 years ago. Modern humans spread across Europe about 40000 years ago. The migrating modern human populations are known to have interbred with local varieties of archaic humans so that contemporary human populations are descended in small part (below 10% contribution) from regional varieties of archaic humans.
