In 57 species of anthropoids relative size of incisors in highly correlated with diet. Anthropoids that feed primarily on large food objects (large fruits) have larger incisors than those that feed on smaller food objects (berries or leaves). This difference reflects a need for more extensive incisal preparation of larger food objects before mastication. Extensive incisal preparation causes increased tooth wear, therefore, enlarged incisors are probably an adaptive response to increase their wear potential.
在57种类人猿中，门牙的相对大小与饮食密切相关。主要以大型食物（大水果）为食的类人猿比以小型食物（浆果或树叶）为食的类人猿有更大的门牙。这种差异反映了在咀嚼前对大型食物进行更广泛切牙准备的需求。广泛的切牙准备会导致牙齿磨损增加，因此，增大的门牙可能是一种适应性反应，以增加其磨损潜力。
