Thème
La main des hominines: une étude comparative de StW 573 et de ses homologues évolutionnaires
This study delves into the complex evolutionary journey of hominin hand morphology, focusing on the StW 573 specimen from the Sterkfontein caves. It meticulously analyzes the wrist and hand bones and reveals how morphological changes mirror the adaptive shifts in hominin lifestyles and environments. Our research juxtaposes StW 573’s hand characteristics with those of other pivotal hominins, such as Ardipithecus ramidus and Australopithecus afarensis, to shed light on the evolutionary trajectory leading to modern human hand features.
It addresses the complex interplay of arboreal and terrestrial adaptations, highlighting how specific morphologies reflect the balance between locomotive and manipulative functions. This comprehensive study enriches our understanding of hominin evolution and adds valuable insights into the broader context of primate morphology and its inferences for human origins.
