Map Description:
This illustrates Ehret's hypothesis regarding the state of agricultural development in Africa circa 3500 B.C.E. The main changes that Ehret points out occur within two particular groups, although all were expanding. As the Cushitic peoples spread west, they began absorbing many former Omotic groups into their societies. Further across the continent, the West African planting agricultural tradition continued spreading to the belt of western rainforest near the Atlantic coast.
