The metric characters of the head and hard palate of 138 black males from Kenya and 110 male !Kung San from Namibia have for the first time been compared to describe the black and Khoisan variation with respect to these special trait systems. The palate measurements were taken from prints of self-hardening plastic. Nearly all metric characters show significant differences between the two populations, which are reflected in a relevant discriminant function. The analyses of correlations between the individual head and palate measurements yield different correlation patterns in the two samples also with regard to their significance and direction. These results and the generally low correlation coefficients can be explained by the complex processes of allometric head growth, resulting in the Sans’ pedomorphous and the blacks’ more adultiform head and palate trait combinations.
