    Beschreibung: The fossil record of the hominin pelvis reflects important evolutionary changes in locomotion and parturition. The partial pelves of two individuals of Australopithecus sediba were reconstructed from previously reported finds and new material. These remains share some features with australopiths, such as large biacetabular diameter, small sacral and coxal joints, and long pubic rami. The specimens also share derived features with Homo, including more vertically oriented and sigmoid-shaped iliac blades, greater robusticity of the iliac body, sinusoidal anterior iliac borders, shortened ischia, and more superiorly oriented pubic rami. These derived features appear in a species with a small adult brain size, suggesting that the birthing of larger-brained babies was not driving the evolution of the pelvis at this time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kibii, Job M -- Churchill, Steven E -- Schmid, Peter -- Carlson, Kristian J -- Reed, Nichelle D -- de Ruiter, Darryl J -- Berger, Lee R -- New York, N.Y. -- Science. 2011 Sep 9;333(6048):1407-11. doi: 10.1126/science.1202521.

    Beschreibung: Arising from M. A. Nowak, C. E. Tarnita & E. O. Wilson 466, 1057-1062 (2010); Nowak et al. reply. Nowak et al. argue that inclusive fitness theory has been of little value in explaining the natural world, and that it has led to negligible progress in explaining the evolution of eusociality. However, we believe that their arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature. We will focus our comments on three general issues.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3836173/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3836173/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Abbot, Patrick -- Abe, Jun -- Alcock, John -- Alizon, Samuel -- Alpedrinha, Joao A C -- Andersson, Malte -- Andre, Jean-Baptiste -- van Baalen, Minus -- Balloux, Francois -- Balshine, Sigal -- Barton, Nick -- Beukeboom, Leo W -- Biernaskie, Jay M -- Bilde, Trine -- Borgia, Gerald -- Breed, Michael -- Brown, Sam -- Bshary, Redouan -- Buckling, Angus -- Burley, Nancy T -- Burton-Chellew, Max N -- Cant, Michael A -- Chapuisat, Michel -- Charnov, Eric L -- Clutton-Brock, Tim -- Cockburn, Andrew -- Cole, Blaine J -- Colegrave, Nick -- Cosmides, Leda -- Couzin, Iain D -- Coyne, Jerry A -- Creel, Scott -- Crespi, Bernard -- Curry, Robert L -- Dall, Sasha R X -- Day, Troy -- Dickinson, Janis L -- Dugatkin, Lee Alan -- El Mouden, Claire -- Emlen, Stephen T -- Evans, Jay -- Ferriere, Regis -- Field, Jeremy -- Foitzik, Susanne -- Foster, Kevin -- Foster, William A -- Fox, Charles W -- Gadau, Juergen -- Gandon, Sylvain -- Gardner, Andy -- Gardner, Michael G -- Getty, Thomas -- Goodisman, Michael A D -- Grafen, Alan -- Grosberg, Rick -- Grozinger, Christina M -- Gouyon, Pierre-Henri -- Gwynne, Darryl -- Harvey, Paul H -- Hatchwell, Ben J -- Heinze, Jurgen -- Helantera, Heikki -- Helms, Ken R -- Hill, Kim -- Jiricny, Natalie -- Johnstone, Rufus A -- Kacelnik, Alex -- Kiers, E Toby -- Kokko, Hanna -- Komdeur, Jan -- Korb, Judith -- Kronauer, Daniel -- Kummerli, Rolf -- Lehmann, Laurent -- Linksvayer, Timothy A -- Lion, Sebastien -- Lyon, Bruce -- Marshall, James A R -- McElreath, Richard -- Michalakis, Yannis -- Michod, Richard E -- Mock, Douglas -- Monnin, Thibaud -- Montgomerie, Robert -- Moore, Allen J -- Mueller, Ulrich G -- Noe, Ronald -- Okasha, Samir -- Pamilo, Pekka -- Parker, Geoff A -- Pedersen, Jes S -- Pen, Ido -- Pfennig, David -- Queller, David C -- Rankin, Daniel J -- Reece, Sarah E -- Reeve, Hudson K -- Reuter, Max -- Roberts, Gilbert -- Robson, Simon K A -- Roze, Denis -- Rousset, Francois -- Rueppell, Olav -- Sachs, Joel L -- Santorelli, Lorenzo -- Schmid-Hempel, Paul -- Schwarz, Michael P -- Scott-Phillips, Tom -- Shellmann-Sherman, Janet -- Sherman, Paul W -- Shuker, David M -- Smith, Jeff -- Spagna, Joseph C -- Strassmann, Beverly -- Suarez, Andrew V -- Sundstrom, Liselotte -- Taborsky, Michael -- Taylor, Peter -- Thompson, Graham -- Tooby, John -- Tsutsui, Neil D -- Tsuji, Kazuki -- Turillazzi, Stefano -- Ubeda, Francisco -- Vargo, Edward L -- Voelkl, Bernard -- Wenseleers, Tom -- West, Stuart A -- West-Eberhard, Mary Jane -- Westneat, David F -- Wiernasz, Diane C -- Wild, Geoff -- Wrangham, Richard -- Young, Andrew J -- Zeh, David W -- Zeh, Jeanne A -- Zink, Andrew -- BB/H022716/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- England -- Nature. 2011 Mar 24;471(7339):E1-4; author reply E9-10. doi: 10.1038/nature09831.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21430721" target="_blank"〉PubMed〈/a〉

    Beschreibung: Despite a rich African Plio-Pleistocene hominin fossil record, the ancestry of Homo and its relation to earlier australopithecines remain unresolved. Here we report on two partial skeletons with an age of 1.95 to 1.78 million years. The fossils were encased in cave deposits at the Malapa site in South Africa. The skeletons were found close together and are directly associated with craniodental remains. Together they represent a new species of Australopithecus that is probably descended from Australopithecus africanus. Combined craniodental and postcranial evidence demonstrates that this new species shares more derived features with early Homo than any other australopith species and thus might help reveal the ancestor of that genus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Berger, Lee R -- de Ruiter, Darryl J -- Churchill, Steven E -- Schmid, Peter -- Carlson, Kristian J -- Dirks, Paul H G M -- Kibii, Job M -- New York, N.Y. -- Science. 2010 Apr 9;328(5975):195-204. doi: 10.1126/science.1184944.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute for Human Evolution, University of the Witwatersrand, Private Bag 3, Wits 2050, South Africa. profleeberger@yahoo.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20378811" target="_blank"〉PubMed〈/a〉

    Beschreibung: The evolution of the human upper limb involved a change in function from its use for both locomotion and prehension (as in apes) to a predominantly prehensile and manipulative role. Well-preserved forelimb remains of 1.98-million-year-old Australopithecus sediba from Malapa, South Africa, contribute to our understanding of this evolutionary transition. Whereas other aspects of their postcranial anatomy evince mosaic combinations of primitive (australopith-like) and derived (Homo-like) features, the upper limbs (excluding the hand and wrist) of the Malapa hominins are predominantly primitive and suggest the retention of substantial climbing and suspensory ability. The use of the forelimb primarily for prehension and manipulation appears to arise later, likely with the emergence of Homo erectus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Churchill, Steven E -- Holliday, Trenton W -- Carlson, Kristian J -- Jashashvili, Tea -- Macias, Marisa E -- Mathews, Sandra -- Sparling, Tawnee L -- Schmid, Peter -- de Ruiter, Darryl J -- Berger, Lee R -- New York, N.Y. -- Science. 2013 Apr 12;340(6129):1233477. doi: 10.1126/science.1233477.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Evolutionary Anthropology, Duke University, Durham, NC 27708, USA. churchy@duke.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23580536" target="_blank"〉PubMed〈/a〉

    Beschreibung: The shape of the thorax of early hominins has been a point of contention for more than 30 years. Owing to the generally fragmentary nature of fossil hominin ribs, few specimens have been recovered that have rib remains complete enough to allow accurate reassembly of thoracic shape, thus leaving open the question of when the cylindrical-shaped chest of humans and their immediate ancestors evolved. The ribs of Australopithecus sediba exhibit a mediolaterally narrow, ape-like upper thoracic shape, which is unlike the broad upper thorax of Homo that has been related to the locomotor pattern of endurance walking and running. The lower thorax, however, appears less laterally flared than that of apes and more closely approximates the morphology found in humans.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmid, Peter -- Churchill, Steven E -- Nalla, Shahed -- Weissen, Eveline -- Carlson, Kristian J -- de Ruiter, Darryl J -- Berger, Lee R -- New York, N.Y. -- Science. 2013 Apr 12;340(6129):1234598. doi: 10.1126/science.1234598.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Anthropological Institute and Museum, University of Zurich, Zurich, Switzerland. smidi@aim.uzh.ch〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23580537" target="_blank"〉PubMed〈/a〉

    Beschreibung: Ionospheric bias corrections associated with radio tracking of spacecraft depend on the following measuring techniques for integrated electron content: (1) Faraday rotation measurements from an earth synchronous satellite; (2) ranging measurements at two frequencies; and (3) group and phase velocity measurements obtained from tracking data. The extraction of the integrated electron content directly from tracking data is achieved by comparison of range-rate measurements based on Doppler shift with differentiated range measurements based on tone delay. This method is most desirable because the measured corrections pertain directly to the spacecraft whose orbit is being determined and can be used in near earth as well as deep space tracking data.
