Recent archaeological discoveries tend to confirm oral histories
common to West African ethnic communities of migration from
the East.

It would appear from the latest archaeological discoveries in the Western Sudan
desert that even the Bantu of South Africa originated in the upper Nile Valley.
Evidence shows that, between 8-5,000 years ago, the tropical rains moved several
hundred kilometers northwards and there was a Yellow Nile leading from the main
Nile into Central Africa. The migration of peoples from Nubia along this river route
is documented in pictures on stone. This correlates, for example,with the tracing of
Bantu roots to Cameroon or Chad.
