Objectives The morphological characteristics of the thumb are of particular interest due to its fundamental role in enhanced manipulation. Despite its possible importance regarding this issue, the body of the first metacarcapal (MC1) has not been fully characterized using morphometrics. This could provide further insights into its anatomy, as well as its relationship with manipulative capabilities. Hence, this study quantifies the shape of the MC1’s body in the extant Homininae and some fossil hominins to provide a better characterization of its morphology.

使用 3D 几何形态测量学表征人科第一掌骨的身体形态

目的拇指的形态特征因其在增强操作中的基本作用而受到特别关注。尽管它在这个问题上可能很重要,但第一掌骨 (MC1) 的身体尚未使用形态测量学完全表征。这可以进一步了解其解剖结构,以及它与操纵能力的关系。因此,这项研究量化了 MC1 在现存人科和一些化石人科中的身体形状,以更好地表征其形态。
