Historical schema III
•The Benue-Congo languages, including Plateau, Cross River, Kainji, Jukunoid and other smaller groups predominate in the centre and east of Nigeria
•They also gave rise to Bantoid and Bantu
•To account for their present distribution, the most likely initial point of dispersal was the Niger-Benue confluence
•Reading back into the past from the probably dates of the Bantu  expansion this must have been 6-7000 kya
•As with Gur-Adamawa, this is primarily a land-based expansion, although on reaching Cross River, fisheries began to play a major role in subsistence
