Abstract
The dentition of early hominids from Laetoli and Hadar provide evidence of "incisal stripping" and a shear-grinding action for C/P3 complex through microscopic examination of wear facets on dental crowns. This masticatory pattern of dental wear resembles that of Papio papio and suggests behavioral analogies between early hominids and Papio.
摘要
通过对牙冠磨损小平面的微观检查，来自莱托利和哈达尔的早期原始人类的牙齿提供了“切缘剥脱”以及C/P3复合体的剪切研磨作用的证据。这种牙齿磨损的咀嚼模式类似于巴氏狒狒的模式，并表明早期原始人类和巴氏狒狒之间存在行为上的相似之处。
