Afroasiatic Urheimat
The term Afroasiatic Urheimat (Urheimat meaning "original homeland" in German) refers to the 'hypothetical' place where Proto-Afroasiatic speakers lived in a single linguistic community, or complex of communities, before this original language dispersed geographically and divided into distinct languages. Afroasiatic languages are today primarily spoken in the Middle East, North Africa, the Horn of Africa, and parts of the Sahel.
There is no agreement on when and where this Urheimat existed, though the language is generally believed to have originated somewhere in or near the region stretching from the Levant/Near East to the area between the Eastern Sahara and the Horn of Africa, including Egypt, Ethiopia and Sudan.
