    A female Homo erectus pelvis from Gona, Ethiopia (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-11-15
    Description: Analyses of the KNM-WT 15000 Homo erectus juvenile male partial skeleton from Kenya concluded that this species had a tall thin body shape due to specialized locomotor and climatic adaptations. Moreover, it was concluded that H. erectus pelves were obstetrically restricted to birthing a small-brained altricial neonate. Here we describe a nearly complete early Pleistocene adult female H. erectus pelvis from the Busidima Formation of Gona, Afar, Ethiopia. This obstetrically capacious pelvis demonstrates that pelvic shape in H. erectus was evolving in response to increasing fetal brain size. This pelvis indicates that neither adaptations to tropical environments nor endurance running were primary selective factors in determining pelvis morphology in H. erectus during the early Pleistocene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simpson, Scott W -- Quade, Jay -- Levin, Naomi E -- Butler, Robert -- Dupont-Nivet, Guillaume -- Everett, Melanie -- Semaw, Sileshi -- New York, N.Y. -- Science. 2008 Nov 14;322(5904):1089-92. doi: 10.1126/science.1163592.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy, Case Western Reserve University School of Medicine, Cleveland, OH 44106-4930, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19008443" target="_blank"〉PubMed〈/a〉

    Paleoanthropology. Late Pliocene fossiliferous sedimentary record and the environmental context of early Homo from Afar, Ethiopia (2015)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2015-03-06
    Description: Sedimentary basins in eastern Africa preserve a record of continental rifting and contain important fossil assemblages for interpreting hominin evolution. However, the record of hominin evolution between 3 and 2.5 million years ago (Ma) is poorly documented in surface outcrops, particularly in Afar, Ethiopia. Here we present the discovery of a 2.84- to 2.58-million-year-old fossil and hominin-bearing sediments in the Ledi-Geraru research area of Afar, Ethiopia, that have produced the earliest record of the genus Homo. Vertebrate fossils record a faunal turnover indicative of more open and probably arid habitats than those reconstructed earlier in this region, which is in broad agreement with hypotheses addressing the role of environmental forcing in hominin evolution at this time. Geological analyses constrain depositional and structural models of Afar and date the LD 350-1 Homo mandible to 2.80 to 2.75 Ma.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉DiMaggio, Erin N -- Campisano, Christopher J -- Rowan, John -- Dupont-Nivet, Guillaume -- Deino, Alan L -- Bibi, Faysal -- Lewis, Margaret E -- Souron, Antoine -- Garello, Dominique -- Werdelin, Lars -- Reed, Kaye E -- Arrowsmith, J Ramon -- New York, N.Y. -- Science. 2015 Mar 20;347(6228):1355-9. doi: 10.1126/science.aaa1415.
