According to Keita (1990) and Livingstone (1967), the Haratin are among the major descendants of the original Saharans. Close similarity in ABO serology between modern Haratin populations and those of ancient Egyptians. These Haratin are considered to be "Negroid" in physical type (Livingstone, 1967). Other serological tests have shown close affinity of certain Berber-speaking groups with tropical Africans in the high rates of cDe, P and V, and low Fy^a antigens (Keita 1990, Mourant et al., 1976, Chamla, 1980). They also group close with West Africans in the high incidence of HbC, HbS and the sickle cell condition (Livingstone, 1967).
However, in terms of phenotype and culture, the Southern Egyptians and Nubians are most closely related to Nile River peoples in the Sudan and to other peoples in adjacent regions. These peoples are, in turn, a blending of the same Saharan type with the type found in the Badari and early Nakada cultures that would fit into the so-called "authentic African" typology.
However, Keita (1993) rightly rejects such an idea of the authentic African, and similar terms like "Forest Negro," "True Negro," etc. He notes that the rejection of relationship between types not both meeting the "True Negro" standard
