The reason I know they are not cacs is because arabs themselves do not claim cac, they consider themselves their own group. I think I will believe arab anthropologists over western ones. Cacs can try to claim their accomplishments, but Arabs are well aware scientifically of who they are. They are native to Arabia, always have, always will. They take pride on being nomads that went outward.i dont agree with arabs being cacs either but legitimate anthropological sources say so, kinda fukked up.
Berbers are African. Some of their tribes leaders 'traded' daughters with the arabs, but they are native to africa, and are not cacs.
