Bantu peoples Bantu peoples is used as a general label for the 300–600 ethnic groups in Africa who speak Bantu languages. They inhabit a geographical area stretching east and southward from Central Africa across the African Great Lakes region down to Southern Africa. Bantu is a major branch of the Niger–Congo language family spoken by most populations in Africa. There are about 650 Bantu languages by the criterion of mutual intelligibility, though the distinction between language and dialect is often unclear, and "Ethnologue" counts 535 languages.
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.
