There is no proof that they acquired sub Saharan DNA from slave trade. All these lies about Egyptians having more SSA genes and Arabs etc is Zionist propaganda. As if all of them have intermingled with Sub Saharan slaves that's utter nonsense. It's deeper than that. I don't believe it one bit.That's what Levantines looked like before they mixed with Black African slaves. Muslim Levantines have 7-12% recent Sub-Saharan African blood from the Arab/Ottoman-African slave trade.
Samaritans have close to 0% or less than 2%.
The SSA slave trade into the Middle East happened AFTER the biblical events occurred (Middle Ages mostly).
