有人认为，人类牙列中牙尖的长期保留是一种相对较新的异常，这是由于现代饮食的磨损性可以忽略不计，为了达到最大的效率和免于疾病，人类牙齿应该像许多食草哺乳动物一样磨损。在这里，我们严格审查的证据，已经提出来支持这一想法，并讨论后，设计的咬合面与各种各样的哺乳动物的饮食，我们得出结论，牙尖是适应打破特定的物理性质的食物。
It has been argued that the prolonged retention of cusps in the human dentition is a relatively recent aberration due to the negligible abrasiveness of modern diets and that to achieve maximum efficiency and freedom from disease human teeth should be worn down as they are in many herbivorous mammals. Here we critically review the evidence that has been put forward to support this idea and, after discussing the design of occlusal surfaces in relation to the wide variety of mammalian diets, we conclude that cusps are adaptations for breaking food with specific physical properties.
