I see this hasn't been discussed here before so I want to hear your thoughts.
The TMRCA of the Somali-specific clade of E-V32 lines up perfectly with Jebel Mokram related migrations from somewhere in the Eastern Desert (ceramics) into the Gash cultural horizon. Then there's the spread of the Ethiopian-Arabian art style that dates to this exact time period, the spread of pastoralism into the Horn of Africa proper too. But it's the linguistic evidence of specifically East Cushitic presence in Lower Nubia when proto-East-Cushitic was spoken (toponyms, names, loanwords), and East Cushitic presence in the Atbara as recent as the 4th century AD makes me really, really confident that we are the descendants of a particularly successful tribe that would've conquered some Gash-related group in Northern Ethiopia (Lake Tana). Would love, love, love to see an investigation into proto (Lowland) East Cushitic contact with proto-Agaw.
