ECON 103 Lecture Notes - Lecture 18: Condyloid Process, Skhul And Qafzeh Hominins, Ulna
Document Summary
12-8 the neandertals retained several traits from the middle pleistocene ancestors that modern humans eventually lost. The discovery of the neandertals also coincided with the publication of origin of species therefore making the neandertal as the first evidence of human evolution. Although there are differences between modern humans and neandertals, neandertals provided the first evidence of human evolution. The proximal ulna of the neandertal compared with the human ulna show anterior to posterior bowing. The neandertals ulna also have larger surface areas showing potential for carrying heavy loads. The relatively large trunk and short ulna show a hyper polar body which is adapted to living in in ice age. The neandertal has larger teeth and ascending ascending ramus though skhul also had notably large teeth. The ascending ramus of the neanderthal show heavy muscle markings, big jaw with comparatively smaller teeth in the neandertal show use of teeth for hide preparation and toolmaking.
