Variation in primate masticatory form and function has been extensively researched through both morphological and experimental studies. As a result, symphyseal fusion in different primate clades has been linked to either the recruitment of vertically directed balancing‐side muscle force, the timing and recruitment of transversely directed forces, or both. This study investigates the relationship between jaw muscle activity patterns and morphology in extant primates to make inferences about masticatory function in extinct primates, with implications for understanding the evolution of symphyseal fusion.

化石灵长类动物的下颌sym突融合:活灵长类动物的颌骨形状和咀嚼功能相关模式的见解

通过形态学和实验研究,广泛研究了灵长类咀嚼形式和功能的变化。结果,在不同的灵长类进化枝中的sym突融合与垂直方向平衡侧肌肉力的募集,横向方向力的时机和募集或两者都有关联。本研究调查了现存灵长类动物下颌肌肉活动模式与形态之间的关系,以推断出已灭绝灵长类动物的咀嚼功能,并有助于理解sym突融合的发展。
