    Beschreibung: 'Orang-utan' is derived from a Malay term meaning 'man of the forest' and aptly describes the southeast Asian great apes native to Sumatra and Borneo. The orang-utan species, Pongo abelii (Sumatran) and Pongo pygmaeus (Bornean), are the most phylogenetically distant great apes from humans, thereby providing an informative perspective on hominid evolution. Here we present a Sumatran orang-utan draft genome assembly and short read sequence data from five Sumatran and five Bornean orang-utan genomes. Our analyses reveal that, compared to other primates, the orang-utan genome has many unique features. Structural evolution of the orang-utan genome has proceeded much more slowly than other great apes, evidenced by fewer rearrangements, less segmental duplication, a lower rate of gene family turnover and surprisingly quiescent Alu repeats, which have played a major role in restructuring other primate genomes. We also describe a primate polymorphic neocentromere, found in both Pongo species, emphasizing the gradual evolution of orang-utan genome structure. Orang-utans have extremely low energy usage for a eutherian mammal, far lower than their hominid relatives. Adding their genome to the repertoire of sequenced primates illuminates new signals of positive selection in several pathways including glycolipid metabolism. From the population perspective, both Pongo species are deeply diverse; however, Sumatran individuals possess greater diversity than their Bornean counterparts, and more species-specific variation. Our estimate of Bornean/Sumatran speciation time, 400,000 years ago, is more recent than most previous studies and underscores the complexity of the orang-utan speciation process. Despite a smaller modern census population size, the Sumatran effective population size (N(e)) expanded exponentially relative to the ancestral N(e) after the split, while Bornean N(e) declined over the same period. Overall, the resources and analyses presented here offer new opportunities in evolutionary genomics, insights into hominid biology, and an extensive database of variation for conservation efforts.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3060778/" 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/PMC3060778/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Locke, Devin P -- Hillier, LaDeana W -- Warren, Wesley C -- Worley, Kim C -- Nazareth, Lynne V -- Muzny, Donna M -- Yang, Shiaw-Pyng -- Wang, Zhengyuan -- Chinwalla, Asif T -- Minx, Pat -- Mitreva, Makedonka -- Cook, Lisa -- Delehaunty, Kim D -- Fronick, Catrina -- Schmidt, Heather -- Fulton, Lucinda A -- Fulton, Robert S -- Nelson, Joanne O -- Magrini, Vincent -- Pohl, Craig -- Graves, Tina A -- Markovic, Chris -- Cree, Andy -- Dinh, Huyen H -- Hume, Jennifer -- Kovar, Christie L -- Fowler, Gerald R -- Lunter, Gerton -- Meader, Stephen -- Heger, Andreas -- Ponting, Chris P -- Marques-Bonet, Tomas -- Alkan, Can -- Chen, Lin -- Cheng, Ze -- Kidd, Jeffrey M -- Eichler, Evan E -- White, Simon -- Searle, Stephen -- Vilella, Albert J -- Chen, Yuan -- Flicek, Paul -- Ma, Jian -- Raney, Brian -- Suh, Bernard -- Burhans, Richard -- Herrero, Javier -- Haussler, David -- Faria, Rui -- Fernando, Olga -- Darre, Fleur -- Farre, Domenec -- Gazave, Elodie -- Oliva, Meritxell -- Navarro, Arcadi -- Roberto, Roberta -- Capozzi, Oronzo -- Archidiacono, Nicoletta -- Della Valle, Giuliano -- Purgato, Stefania -- Rocchi, Mariano -- Konkel, Miriam K -- Walker, Jerilyn A -- Ullmer, Brygg -- Batzer, Mark A -- Smit, Arian F A -- Hubley, Robert -- Casola, Claudio -- Schrider, Daniel R -- Hahn, Matthew W -- Quesada, Victor -- Puente, Xose S -- Ordonez, Gonzalo R -- Lopez-Otin, Carlos -- Vinar, Tomas -- Brejova, Brona -- Ratan, Aakrosh -- Harris, Robert S -- Miller, Webb -- Kosiol, Carolin -- Lawson, Heather A -- Taliwal, Vikas -- Martins, Andre L -- Siepel, Adam -- Roychoudhury, Arindam -- Ma, Xin -- Degenhardt, Jeremiah -- Bustamante, Carlos D -- Gutenkunst, Ryan N -- Mailund, Thomas -- Dutheil, Julien Y -- Hobolth, Asger -- Schierup, Mikkel H -- Ryder, Oliver A -- Yoshinaga, Yuko -- de Jong, Pieter J -- Weinstock, George M -- Rogers, Jeffrey -- Mardis, Elaine R -- Gibbs, Richard A -- Wilson, Richard K -- G0501331/Medical Research Council/United Kingdom -- HG002238/HG/NHGRI NIH HHS/ -- HG002385/HG/NHGRI NIH HHS/ -- MC_U137761446/Medical Research Council/United Kingdom -- P01 AG022064/AG/NIA NIH HHS/ -- R01 GM059290/GM/NIGMS NIH HHS/ -- R01 GM59290/GM/NIGMS NIH HHS/ -- R01 HG002939/HG/NHGRI NIH HHS/ -- U54 HG003079/HG/NHGRI NIH HHS/ -- U54 HG003079-08/HG/NHGRI NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Medical Research Council/United Kingdom -- England -- Nature. 2011 Jan 27;469(7331):529-33. doi: 10.1038/nature09687.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉The Genome Center at Washington University, Washington University School of Medicine, 4444 Forest Park Avenue, Saint Louis, Missouri 63108, USA. dlocke@wustl.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21270892" target="_blank"〉PubMed〈/a〉

    Beschreibung: Confidence is an essential ingredient of success in a wide range of domains ranging from job performance and mental health to sports, business and combat. Some authors have suggested that not just confidence but overconfidence--believing you are better than you are in reality--is advantageous because it serves to increase ambition, morale, resolve, persistence or the credibility of bluffing, generating a self-fulfilling prophecy in which exaggerated confidence actually increases the probability of success. However, overconfidence also leads to faulty assessments, unrealistic expectations and hazardous decisions, so it remains a puzzle how such a false belief could evolve or remain stable in a population of competing strategies that include accurate, unbiased beliefs. Here we present an evolutionary model showing that, counterintuitively, overconfidence maximizes individual fitness and populations tend to become overconfident, as long as benefits from contested resources are sufficiently large compared with the cost of competition. In contrast, unbiased strategies are only stable under limited conditions. The fact that overconfident populations are evolutionarily stable in a wide range of environments may help to explain why overconfidence remains prevalent today, even if it contributes to hubris, market bubbles, financial collapses, policy failures, disasters and costly wars.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Johnson, Dominic D P -- Fowler, James H -- England -- Nature. 2011 Sep 14;477(7364):317-20. doi: 10.1038/nature10384.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Politics and International Relations, University of Edinburgh, Edinburgh EH8 9LD, UK. dominic.johnson@ed.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/21921915" target="_blank"〉PubMed〈/a〉

    Beschreibung: Neuroanatomically precise, genome-wide maps of transcript distributions are critical resources to complement genomic sequence data and to correlate functional and genetic brain architecture. Here we describe the generation and analysis of a transcriptional atlas of the adult human brain, comprising extensive histological analysis and comprehensive microarray profiling of approximately 900 neuroanatomically precise subdivisions in two individuals. Transcriptional regulation varies enormously by anatomical location, with different regions and their constituent cell types displaying robust molecular signatures that are highly conserved between individuals. Analysis of differential gene expression and gene co-expression relationships demonstrates that brain-wide variation strongly reflects the distributions of major cell classes such as neurons, oligodendrocytes, astrocytes and microglia. Local neighbourhood relationships between fine anatomical subdivisions are associated with discrete neuronal subtypes and genes involved with synaptic transmission. The neocortex displays a relatively homogeneous transcriptional pattern, but with distinct features associated selectively with primary sensorimotor cortices and with enriched frontal lobe expression. Notably, the spatial topography of the neocortex is strongly reflected in its molecular topography-the closer two cortical regions, the more similar their transcriptomes. This freely accessible online data resource forms a high-resolution transcriptional baseline for neurogenetic studies of normal and abnormal human brain function.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4243026/" 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/PMC4243026/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hawrylycz, Michael J -- Lein, Ed S -- Guillozet-Bongaarts, Angela L -- Shen, Elaine H -- Ng, Lydia -- Miller, Jeremy A -- van de Lagemaat, Louie N -- Smith, Kimberly A -- Ebbert, Amanda -- Riley, Zackery L -- Abajian, Chris -- Beckmann, Christian F -- Bernard, Amy -- Bertagnolli, Darren -- Boe, Andrew F -- Cartagena, Preston M -- Chakravarty, M Mallar -- Chapin, Mike -- Chong, Jimmy -- Dalley, Rachel A -- Daly, Barry David -- Dang, Chinh -- Datta, Suvro -- Dee, Nick -- Dolbeare, Tim A -- Faber, Vance -- Feng, David -- Fowler, David R -- Goldy, Jeff -- Gregor, Benjamin W -- Haradon, Zeb -- Haynor, David R -- Hohmann, John G -- Horvath, Steve -- Howard, Robert E -- Jeromin, Andreas -- Jochim, Jayson M -- Kinnunen, Marty -- Lau, Christopher -- Lazarz, Evan T -- Lee, Changkyu -- Lemon, Tracy A -- Li, Ling -- Li, Yang -- Morris, John A -- Overly, Caroline C -- Parker, Patrick D -- Parry, Sheana E -- Reding, Melissa -- Royall, Joshua J -- Schulkin, Jay -- Sequeira, Pedro Adolfo -- Slaughterbeck, Clifford R -- Smith, Simon C -- Sodt, Andy J -- Sunkin, Susan M -- Swanson, Beryl E -- Vawter, Marquis P -- Williams, Derric -- Wohnoutka, Paul -- Zielke, H Ronald -- Geschwind, Daniel H -- Hof, Patrick R -- Smith, Stephen M -- Koch, Christof -- Grant, Seth G N -- Jones, Allan R -- 066717/Wellcome Trust/United Kingdom -- 077155/Wellcome Trust/United Kingdom -- 1C76HF15069-01-00/PHS HHS/ -- 1C76HF19619-01-00/PHS HHS/ -- G0700399/Medical Research Council/United Kingdom -- G0802238/Medical Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2012 Sep 20;489(7416):391-9. doi: 10.1038/nature11405.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Allen Institute for Brain Science, Seattle, Washington 98103, USA. mikeh@alleninstitute.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22996553" target="_blank"〉PubMed〈/a〉

    Beschreibung: Evolution involves interplay between natural selection and developmental constraints. This is seen, for example, when digits are lost from the limbs during evolution. Extant archosaurs (crocodiles and birds) show several instances of digit loss under different selective regimes, and show limbs with one, two, three, four or the ancestral number of five digits. The 'lost' digits sometimes persist for millions of years as developmental vestiges. Here we examine digit loss in the Nile crocodile and five birds, using markers of three successive stages of digit development. In two independent lineages under different selection, wing digit I and all its markers disappear. In contrast, hindlimb digit V persists in all species sampled, both as cartilage, and as Sox9- expressing precartilage domains, 250 million years after the adult digit disappeared. There is therefore a mismatch between evolution of the embryonic and adult phenotypes. All limbs, regardless of digit number, showed similar expression of sonic hedgehog (Shh). Even in the one-fingered emu wing, expression of posterior genes Hoxd11 and Hoxd12 was conserved, whereas expression of anterior genes Gli3 and Alx4 was not. We suggest that the persistence of digit V in the embryo may reflect constraints, particularly the conserved posterior gene networks associated with the zone of polarizing activity (ZPA). The more rapid and complete disappearance of digit I may reflect its ZPA-independent specification, and hence, weaker developmental constraints. Interacting with these constraints are selection pressures for limb functions such as flying and perching. This model may help to explain the diverse patterns of digit loss in tetrapods. Our study may also help to understand how selection on adults leads to changes in development.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉de Bakker, Merijn A G -- Fowler, Donald A -- den Oude, Kelly -- Dondorp, Esther M -- Navas, M Carmen Garrido -- Horbanczuk, Jaroslaw O -- Sire, Jean-Yves -- Szczerbinska, Danuta -- Richardson, Michael K -- England -- Nature. 2013 Aug 22;500(7463):445-8. doi: 10.1038/nature12336.
