 Blench even wonders whether the highly divergent Gurage languages indicate an origin in Ethiopia (with the rest of Ethiopic Semitic a later back migration).Identification of the hypothetical proto-Semitic region of origin is therefore dependent on the larger geographic distributions of the other language families within Afroasiatic, whose origins are also hotly debated.According to Christy G. Turner II, there is an archaeological and physical anthropological reason for a relation between the modern Semitic-speaking populations of the Levant and the Natufian culture.
