Predynastic Egypt

According to bioarchaeologist Nancy Lovell, the morphology of ancient Egyptian skeletons gives strong evidence that: "In general, the inhabitants of Upper Egypt and Nubia had the greatest biological affinity to people of the Sahara and more southerly areas", but exhibited local variation in an African context. S. O. Y. Keita, a biological anthropologist also reviewed studies on the biological affinities of the Ancient Egyptian population and characterised the skeletal morphologies of predynastic southern Egyptians as a "Saharo-tropical African variant". Keita also added that it is important to emphasize that whilst Egyptian society became more socially complex and biologically varied, the "ethnicity of the Niloto-Saharo-Sudanese origins did not change. The cultural morays, ritual formulae, and symbols used in writing, as far as can be ascertained, remained true to their southern origins."
