Previous analyses of cranial variation found the Badari and Early Predynastic Egyptians to be more similar to other African groups than to Mediterranean or European populations(Keita, 1990; Zakrzewski, 2002). In addition, the Badarians have been described as near the centroid of cranial and dental variation among Predynastic and Dynastic populations studied (Irish, 2006; Zakrzewski, 2007). This suggests that, at least through the Early Dynastic period, the inhabitants of the Nile valley were a continuous population of local origin, and no major migration or replacement events occurred during this time.
Studies of cranial morphology also support the use of a Nubian (Kerma) population for a comparison of the Dynastic period, as this group is likely to be more closely genetically related to the early Nile valley inhabitants than would be the Late Dynastic Egyptians, who likely experienced significant mixing with other Mediterranean populations(Zakrzewski, 2002). A craniometric study found the Naqada and Kerma populations to be morphologically similar (Keita, 1990). Given these and other prior studies suggesting continuity (Berry et al., 1967; Berry and Berry, 1972), and the lack of archaeological evidence of major migration or population replacement during the Neolithic transition in the Nile valley, we may cautiously interpret the dental health changes over time as primarily due to ecological, subsistence, and demographic changes experienced throughout the Nile valley region.”
