Abstract
Normative adontometric data are presented on a sample of 100 adult Cercopithecus aethiops(51 male, 49 female). When correlation effects among the teeth were held constant through multivariate canonical analyses, contributions of individual tooth loci to the male-female distance were found to be similar to those isolated by univariate means. The present study fails to support Garn’s field theory of sex dimorphism. When these patterns of sexual dimorphism were contrasted with those of three other conspecific groups, the anterior teeth were found to show greater intrapopulation variation than the posterior teeth. This, together with the finding that Penrose’s shape distances between the groups were greater for anterior than postcanine teeth, provides evidence in support of Suolé’s hypothesis. The latter suggests, inter alia, that high coefficients of variation indicate a proportionately higher environmental than hereditary contribution to phenotypic variation. Negative correlations between tooth size and coefficients of variation suggest that tooth-size variability is related to size rather than occlusal complexity.
