Degree of pelvic sexual dimorphism in human populations. A greene t-test application

The knowledge of sexual dimorphisms is important in many aspects of paleodemography and paleobiology. One major problem lies in a correct sexual diagnosis. However, due to the different methodologies employed to estimate the degree of sexual dimorphism, the comparison of the results remains difficult. The Greene t-test (1989) is accurate for a comparative analysis of raw data. On the basis of 18 measurements of theos coxae the test is made to evaluate the degree of sexual dimorphism. The data collected are employed to investigate the pelvic sexual dimorphism within a recent sample of known sex, and among the Afalou-bou Rhummel — Taforalt (Epipaleolithic of Northern Africa) and the Teviec — Hoedic samples (Mesolithic of France). A comparative analysis is applied to a few recent samples. The results indicate the stability of sexual dimorphism pattern in recent and past populations.
