The Giles hypothesis posits that differences in the cranial morphology of Pan troglodytes and Gorilla gorilla are largely the result of allometric scaling. However, previous support for the Giles hypothesis was based on bivariate plots of linear measurements. This investigation uses geometric morphometric methods to retest this hypothesis and its prediction that extending the ontogenetic trajectory of a chimpanzee would produce an adult gorilla‐like cranial morphology.

使用几何形态计量学检验Giles假设

吉尔斯假说认为，潘氏穴居人和大猩猩大猩猩的颅骨形态差异在很大程度上是异速结垢的结果。但是，先前对Giles假设的支持是基于线性测量的双变量图。这项研究使用几何形态计量学方法重新检验了这一假设及其预测，即扩大黑猩猩的个体发育轨迹将产生成年大猩猩状的颅骨形态。
