These Sudanese Al-Khiday men represent the “Cushitics” of that time. You see I refrain from making definitive statements because we’re clearly lacking samples. The people could have been your ancestors or their sister groups. There were multiple lakes in the once lush Green Sahara and people migrated using these and the wadis as conduits.
That being said, I do not think Cushitics reached Iberia. As mercenaries during antiquity, probably (since there was a Nubian mercenary in Serbia). But ancient times? Most likely not. Cushitic territory is Eastern Sahara. Morocco & Iberia are too West for them. Iberia and Italy did have some IBM or IAM input though. During Etruscan times or prior.
Aye, I do not think any PPNB migration of significance reached Nubia. PPNB were farmers so they wouldn’t like the Eastern Desert, either.
Yup. The Levant was genetically pierced from all directions. Ever think why there are so many Es there?

That’s just bringing in the Egyptian introgression to the Levant. I haven’t even started on Assyrians, Amorties, Iranians, and Sumerians.
Poor Natufians. They didn’t stand a chance against tall farmers from Zagros and Anatolia.
