African Agriculture ca. 5500 BCE
Ehret, Christopher. 2002. The civilizations of Africa: A history to 1800. Charlottesville: University Press of Virginia.
This map displays the state and distribution of agricultural practices in Africa circa 5500 BCE. The Omotic culture was slowly being absorbed by expanding Cushitic agripastoralists, while Middle Eastern pastoralists were spreading through the Arabian peninsula to parts of Asia and Europe. The map African Agriculture ca. 3500 BCE further illustrates Ehret's historical hypothesis regarding the distribution of techniques and peoples in the northern half of the continent (Ehret).
