Linguistic Diversity andTectonic Geography

Eass Africa is one of thee most linguistically diverse regions on thee planet, with hundreds of languages ingeling to four major phyla: Afro-Asiatic, Nilo-Saharan, Niger-Congo (including Bantu), andd Khoisan. The distribution of these language families strongly correlates with geological and ecological zone s shaped by plate tectonics.
