Neolithic to Proto-Dynastic

The natural scientist Frederick Falkenburger in 1947, based on a sample set of around 1,800 prehistoric Egyptian crania, noted great heterogeneity amongst his samples. Falkenburger categorized them based on the nasal index, overall head and face form, taking into account width, eye socket structure, amongst other given indicators. He divided and characterized the skulls into four types: Cro-Magnon type, "Negroid" type, Mediterranean type, and mixed types resulting from the mixture of the aforementioned groups. Similarly, the craniometrics of early Egyptians were according to the physician and anthropologist Eugene Strouhal in 1971, designated as either Cro-Magnon of North Africa, Mediterranean, "Negroid" of East Africa, and intermediate/mixed.

According to professor Fekhri A. Hassan, the peopling of the Egyptian Nile Valley from archaeological and biological data, was the result of a complex interaction between coastal northern Africans, “neolithic” Saharans, Nilotic hunters, and riverine proto-Nubians with some influence and migration from the Levant (Hassan, 1988).
