| Abstract | |
Since discovery and description of the species, Sahelanthropus tchadensis has been at the centre of a great discussion around its classification as a hominin - the first of our lineage - or an ape. Many studies have been conducted in order to clarify this question, especially studies based on the morphology of the cranium and the post-cranial remains. In this study, we analysed the posterior dentition of S. tchadensis in relation to those of other hominins and chimpanzees, using a multivariate comparative metric analysis. Our results suggest that the posterior dentition of the Chad material lies in the range of well-established early Plio-Pleistocene hominins, supporting its classification as part of the hominin lineage. SIGNIFICANCE: • The subject investigated in this study is important to the understanding of the first steps of human evolution. • Much has been discussed about this Chadian species. Some believe it is the first hominin, others believe it is an ape. • This study shows that the posterior dentition of S. tchadensis does not preclude it from being a hominin. (AU) | |
