The morphometric affinities of the 33,000 year old skeleton from Nazlet Khater, Upper Egypt are examined using multivariate statistical procedures. In the first part, principal components analysis is performed on a dataset of mandible dimensions of 220 fossils, sub-fossils and modern specimens, ranging in time from the Late Pleistocene to recent and restricted in space to the African continent and Southern Levant. In the second part, mean measurements for various prehistoric and modern African and Levantine populations are incorporated in the statistical analysis. Subsequently, differences between male and female means are examined for some of the modern and prehistoric populations. The results indicate a strong association between some of the sub-Saharan Middle Stone Age (MSA) specimens, and the Nazlet Khater mandible. Furthermore, the results suggest that variability between African populations during the Neolithic and Protohistoric periods was more pronounced than the range of variability observed among recent African and Levantine populations. Results also demonstrate a general reduction in the degree of sexual dimorphism during the Holocene. However, this pattern of reduction pattern varies by geographic location and is not uniform across the African continent.
