Early human migrations
Early human migrations and expansions of archaic and modern humans across continents began 2 million years ago with the migration out of Africa by Homo erectus. This was followed by the migrations of other pre-modern humans including H. heidelbergensis, the likely ancestor of both modern humans and Neanderthals. Finally, Homo sapiens ventured out of Africa around 200,000 years ago, spread across Asia from 75,000 years ago and arrived on new continents and islands since then.Knowledge of early human migrations, a major topic of archeology, has been achieved by the study of human fossils, occasionally by stone-age artifacts. and more recently has been assisted by archaeogenetics Cultural and ethnic migrations are estimated by combining archaeogenetics and comparative linguistics.
