Description:
Thorpe et al. (Reports, 1 June 2007, p. 1328) concluded that human bipedalism evolved from a type of bipedal posture they observed in extant orangutans with seemingly human-like extended knees. However, humans share knuckle-walking characters with African apes that are absent in orangutans. These are most parsimoniously explained by positing a knuckle-walking precursor to human bipedalism.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Begun, D R -- Richmond, B G -- Strait, D S -- New York, N.Y. -- Science. 2007 Nov 16;318(5853):1066; author reply 1066.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, University of Toronto, Toronto, ON, M5S 2S2, Canada. begun@chass.utoronto.ca〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18006725" target="_blank"〉PubMed〈/a〉
