| Abstract: | The KNM-ER 999 hominid femur, in light of improved knowledge of later Pleistocene human postcranial morphology and ongoing reassessments of the emergence of modern humans in Africa, appears morphologically aligned with early modern humans rather than with late archaic humans. This is reflected especially in its having a clear pilaster, a proximally positioned minimum diaphyseal breadth (thereby lacking a proximo-medial diaphyseal buttress) and an exceptionally high neck-shaft angle. In these features, and especially the fast, it shows affinities to the Levantine Qafzeh-Skhul early modern human sample. However, the uncertainty regarding its stratigraphic provenience (early Late Pleistocene versus early Holocene) makes its relevance to the emergence of modern humans in Africa tenuous. |
