| Abstract: | Data are presented on non-metric dental morphological traits in skeletal samples from the Lower Nubian A-Group (ca. 3100–2500 BC) and C-Group (ca. 2000–1500 BC) cultural periods. In order to examine possible biological differentiation between these two periods, their trait frequencies were analysed using the mean measure of divergence statistic. Results indicate biological continuity, consistent with in situ evolution, although the problem of small samples requires that these results be accepted with caution. Although the diffusion of ideas or material culture into the area through military and trade contacts is likely, any archaeologically observable cultural differences between these two phases are more consistent with local cultural evolution than with the importation of a new cultural system through the migration of a foreign population into the area. The timing of a population replacement in ancient Nubia that has been identified by other scholars should now be sought either before the A-Group period or after the C-Group. |
