Univariate and multivariate statistical analyses are applied to a number of cranial dimensions and angles from living hominoids in order to investigate the patterns of sexual dimorphism in these groups. Clear differences in patterns of cranial sexual dimorphisms are demonstrated not only between genera but also within a single species (Homo). These differences overlay the common finding of a sexual size difference in all groups. The results imply that caution is required in using the sexual dimorphisms of living hominoids as models for those anticipated in fossils.
对现存类人猿的一些颅骨尺寸和角度进行单变量和多变量统计分析，以研究这些群体中的两性异形模式。结果表明，不仅不同属之间，而且在单个物种（智人）内部，颅骨两性异形模式都存在明显差异。这些差异叠加了所有群体中常见的两性大小差异。结果表明，在将现存类人猿的两性异形作为化石中预期的两性异形模型时需要谨慎。
