Eurasian backflow The Eurasian backflow was a recent migration of humans from western Eurasia back to East Africa. "Homo sapiens" had left Africa about 100,000 years ago, and about 3,000 years ago farmers from Anatolia and the Near East migrated back to the Horn of Africa. Signs of this migration can be found in the genomes of contemporary people from all over East Africa.
