Sub-Saharan Africans show unique dental morphology differing significantly from North Africans, Europeans, Southeast Asians, Northeast Asians, New World groups, Australians/Tasmanians, and Melanesians. Sub-Saharan dentition features mass-additive crown and root traits absent or rare in other world populations. These unique traits appear in earlier hominids, extinct non-human primates, and extant non-human primates. Sub-Saharan Africans exhibit highest frequency of ancestral dental features shared with primitive forms. Phenetic dental expression approximates underlying genetic variation. Sub-Saharan Africans display least dental divergence from Plio-Pleistocene ancestral hominid state. Intra- and inter-population dental variability supports Sub-Saharan uniqueness. Dental data provides evidence against Out-of-Africa model for modern human origins. Sub-Saharan dentition shows no convergence toward derived states seen in other groups. Ancestral traits dominate Sub-Saharan dental profile relative to global samples.
