Previous studies have shown that frugivorous anthropoids have wider incisors than folivores relative to body mass, and that catarrhines have relatively wider incisors than platyrrhines. This study reexamines these contrasts using mandibular length as a biomechanical standard to quantify relative incisor width.

类人猿门牙大小的功能和系统发育变异

先前的研究表明，相对于体重而言，食果类人猿的门牙比食叶类更宽，而卡他林类的门牙比桔梗类更宽。本研究使用下颌长度作为生物力学标准来重新检查这些对比，以量化相对切牙宽度。
