Cattle-Keeping and Milking in Eastern and Southern African History: The Linguistic Evidence

Cattle have been known in northern East Africa for a long time. A single people initiated the spread of cattle farther south through southern East Africa, and partly into southern Africa, at a time prior to the expansion of Bantu-speakers into these regions. This spread was not accompanied by knowledge of milking. The milking of cattle, although very likely practiced by some northern East African peoples since a very early period, diffused to Bantu peoples after their advance into eastern and southern Africa was well under way. The practice was probably borrowed from Southern Cushites first by Bantu in northern Tanganyika and through them transmitted to the rest of the eastern and southern Bantu.
