Abstract

We analyze the multivariate pattern of lower and upper cheek dentition for the family Hyaenidae along its evolutionary history. A total of 11,698 individual measurements of lengths and widths for the main postcanine teeth were collected for 54 extinct and three extant species of this family and analyzed by means of principal component analyses. Our results indicate that the functional aspects are better reflected by lower cheek dentition as a result of mosaic evolution. The multivariate structure captured by the three first principal components correspond to different adaptive strategies. The two first components characterize the main groups of ecomorphs, while hunting species separate from scavengers along the third axis. In the context of Hyaenidae, the post-canine cheek dentition of and shows an extreme degree of specialization in scavenging.

摘要

我们分析了鬣狗科在其进化历史中上下颊齿列的多变量模式。针对该科54种已灭绝和3种现存物种，共收集了11698个主要犬后齿长度和宽度的个体测量数据，并通过主成分分析进行了分析。我们的结果表明，由于镶嵌进化，功能方面在下颊齿列中得到了更好的体现。前三个主成分所捕捉到的多变量结构对应于不同的适应策略。前两个成分表征了主要的生态形态组，而捕猎物种沿第三轴与食腐动物区分开来。在鬣狗科的背景下， 和 的犬后颊齿列在食腐方面表现出极高的特化程度。
