5000 BCE: (Who Domesticated the Donkey — Genetic Evidence Pointing to Two Separate Domestications by Cushitic-Speaking Peoples in the Horn of Africa, One in Somaliland and Another Along the Red Sea Hills, a Cushitic Linguistic Root Distinguishing Domestic from Wild Donkeys Datable to Approximately 5000 BCE, Consistent with Both the Genetic Dating and the Archaeological Appearance of Domestic Donkeys After 4000 BCE in Egypt): Ehret poses the question directly: who domesticated the donkey? The genetic evidence provides a striking answer. Communities in Somaliland in the Horn of Africa and also farther north along the Red Sea Hills apparently participated separately in the domestication of this critically important animal. In both regions, the local people would have spoken early languages of the Cushitic branch of the Afrasian (Afroasiatic) language family, and in that branch linguists can track a word distinguishing domestic donkeys from wild donkeys back to a period roughly in the range of 5000 BCE. This linguistic dating is consistent with the genetic dating of domestic donkeys and with their archaeological appearance after 4000 BCE in Egypt. Here again is the correlative methodology that gives Ehret’s work its distinctive power: genetics, linguistics, and archaeology all converging on the same conclusion, each independent line of evidence reinforcing the others. Two separate African communities, both Cushitic-speaking, both living in the Horn of Africa, independently domesticated the same animal — and in doing so set in motion a chain of consequences that would reshape transport, trade, warfare, and political organization across the entire ancient world. The donkey’s journey from Somaliland to Sumer is one of the great untold stories of world history.
