Ten angular measurements have been retained for a study of the basis of the skull for two species of chimpanzees : Pan troglodytes (83 skulls) and Pan paniscus (179 skulls). Were especially studied : growth and sexual or specific differences. Classical parameters or angles measured in reference to the horizontal vestibular axis were used. The statistical study clearly shows the phenomenom of negative rotation with an ontogenic accentuation of quadrupedia.
为了研究两种黑猩猩——普通黑猩猩（83个颅骨）和倭黑猩猩（179个颅骨）的颅骨基部，保留了10个角度测量值。特别研究了：生长以及性别或物种差异。使用了参照水平前庭轴测量的经典参数或角度。统计研究清楚地显示了负旋转现象，且四足动物个体发育过程中这种现象更为明显。
