-- The Khoisan have been pushed all the way down to South Africa deserts, notably by the Bantu expansion of 1,000 years ago.
-- Somalis were hinterland people before trekking to the coast; coastal lowlands were basically 'foreign' kingdoms and invasions prior to 750 BC.
-- Afro-Asiatic expansion started 7,700 BC from Sudan/Beja territory, didn't reach the Horn until 6,500 BC.
-- But, but, Beesha T, where were we? Were we still in Anatolia?
-- Proto-Cushites 6,000 BC. Beesha T are not Cushites.
-- Cushites split into Northern, Eastern and Lower, 5,000 BC-3,000 BC.
-- Further Lower Cushitic breakdown, 1,700 BC.
-- Midget Sabeans arrive from Yemen in 950 BC.
-- Somali expansion begins 550 AD.
Fascinating time frames. There is even a port called Port of Isis in the Zeilac region.
Beesha T, while haven't been in the region as long as the Cushites (differentiate that from Somalis), but arrived in the Horn, Somali peninsula, the same time as Somalis of Cushitic extraction.
Somali language has about 25%-30% commonality with Afaan Oromo, another Afro-Asiatic language. I think Beesha T, when it arrived in the Horn, spoke different language, perhaps even Aramaic/Semitic language, Prophet Jesus (Issa) native tongue...just a guess. Damn, we lost a lot coming to the Dark Continent
