Sudanese Arabs have substantial Arab ancestry
What did you use for the "Cushitic" proxy? Somalis? The "Cushites" they mixed with would've been substantially more "Ethio-Somali" than we are, and so it's not right using them as a proxy, no? I have 80% Somali + 20% Natufian and 80% Somali + 20% Ethio-Somali (87% Natufian + 13% IBM) coords if you could please try that again with it.
