    Description: As the largest predators of the Cambrian seas, the anomalocaridids had an important impact in structuring the first complex marine animal communities, but many aspects of anomalocaridid morphology, diversity, ecology, and affinity remain unclear owing to a paucity of specimens. Here we describe the anomalocaridid Hurdia, based on several hundred specimens from the Burgess Shale in Canada. Hurdia possesses a general body architecture similar to those of Anomalocaris and Laggania, including the presence of exceptionally well-preserved gills, but differs from those anomalocaridids by possessing a prominent anterior carapace structure. These features amplify and clarify the diversity of known anomalocaridid morphology and provide insight into the origins of important arthropod features, such as the head shield and respiratory exites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Daley, Allison C -- Budd, Graham E -- Caron, Jean-Bernard -- Edgecombe, Gregory D -- Collins, Desmond -- New York, N.Y. -- Science. 2009 Mar 20;323(5921):1597-600. doi: 10.1126/science.1169514.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Earth Sciences, Palaeobiology, Uppsala University, Villavagen 16, Uppsala SE-752 36, Sweden. allison.daley@geo.uu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19299617" target="_blank"〉PubMed〈/a〉

    Description: The molecular mechanisms underlying major phenotypic changes that have evolved repeatedly in nature are generally unknown. Pelvic loss in different natural populations of threespine stickleback fish has occurred through regulatory mutations deleting a tissue-specific enhancer of the Pituitary homeobox transcription factor 1 (Pitx1) gene. The high prevalence of deletion mutations at Pitx1 may be influenced by inherent structural features of the locus. Although Pitx1 null mutations are lethal in laboratory animals, Pitx1 regulatory mutations show molecular signatures of positive selection in pelvic-reduced populations. These studies illustrate how major expression and morphological changes can arise from single mutational leaps in natural populations, producing new adaptive alleles via recurrent regulatory alterations in a key developmental control gene.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3109066/" 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/PMC3109066/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Chan, Yingguang Frank -- Marks, Melissa E -- Jones, Felicity C -- Villarreal, Guadalupe Jr -- Shapiro, Michael D -- Brady, Shannon D -- Southwick, Audrey M -- Absher, Devin M -- Grimwood, Jane -- Schmutz, Jeremy -- Myers, Richard M -- Petrov, Dmitri -- Jonsson, Bjarni -- Schluter, Dolph -- Bell, Michael A -- Kingsley, David M -- P50 HG002568/HG/NHGRI NIH HHS/ -- P50 HG002568-09/HG/NHGRI NIH HHS/ -- P50 HG02568/HG/NHGRI NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2010 Jan 15;327(5963):302-5. doi: 10.1126/science.1182213.

    Description: Morphological diversity within closely related species is an essential aspect of evolution and adaptation. Mutations in the Melanocortin 1 receptor (Mc1r) gene contribute to pigmentary diversity in natural populations of fish, birds, and many mammals. However, melanism in the gray wolf, Canis lupus, is caused by a different melanocortin pathway component, the K locus, that encodes a beta-defensin protein that acts as an alternative ligand for Mc1r. We show that the melanistic K locus mutation in North American wolves derives from past hybridization with domestic dogs, has risen to high frequency in forested habitats, and exhibits a molecular signature of positive selection. The same mutation also causes melanism in the coyote, Canis latrans, and in Italian gray wolves, and hence our results demonstrate how traits selected in domesticated species can influence the morphological diversity of their wild relatives.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2903542/" 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/PMC2903542/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Anderson, Tovi M -- vonHoldt, Bridgett M -- Candille, Sophie I -- Musiani, Marco -- Greco, Claudia -- Stahler, Daniel R -- Smith, Douglas W -- Padhukasahasram, Badri -- Randi, Ettore -- Leonard, Jennifer A -- Bustamante, Carlos D -- Ostrander, Elaine A -- Tang, Hua -- Wayne, Robert K -- Barsh, Gregory S -- P01 DK068384/DK/NIDDK NIH HHS/ -- P01 DK068384-050001/DK/NIDDK NIH HHS/ -- R01 GM068882/GM/NIGMS NIH HHS/ -- R01 GM068882-04/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2009 Mar 6;323(5919):1339-43. doi: 10.1126/science.1165448.

    Description: The long-term effects of mass extinctions on spatial and evolutionary dynamics have been poorly studied. Here we show that the evolutionary consequences of the end-Cretaceous [Cretaceous/Paleogene (K/Pg)] mass extinction persist in present-day biogeography. The geologic ages of genera of living marine bivalves show a significant break from a smooth exponential distribution, corresponding to the K/Pg boundary. The break reflects a permanent increase in origination rates, intermediate between the Mesozoic rate and the post-extinction recovery pulse. This global rate shift is most clearly seen today in tropical bioprovinces and weakens toward the poles. Coupled with the modern geographic distributions of taxa originating before and after the K/Pg boundary, this spatial pattern indicates that tropical origination rates after the K/Pg event have left a permanent mark on the taxonomic and biogeographic structure of the modern biota, despite the complex Cenozoic history of marine environments.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Krug, Andrew Z -- Jablonski, David -- Valentine, James W -- New York, N.Y. -- Science. 2009 Feb 6;323(5915):767-71. doi: 10.1126/science.1164905.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geophysical Sciences, University of Chicago, 5734 South Ellis Avenue Chicago, IL 60637, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19197060" target="_blank"〉PubMed〈/a〉

    Description: Classification was a key practice of the natural history sciences in the early 19th century, but leading taxonomists disagreed over basic matters, such as how many species the British flora contained. In this arena, the impact of Charles Darwin's ideas was surprisingly limited. For taxonomists like Darwin's friend, Joseph Dalton Hooker, the priority was to establish a reputation as a philosophical naturalist, and to do so Hooker embarked on a survey of global vegetation patterns. He believed that taxonomic "splitters" hindered his ambition to create natural laws for botany (and hence establish it as a prestigious science) by generating a multitude of redundant synonyms for every plant variety. Despite the fact that Darwin's ideas apparently promised a justification for splitting, they also offered a philosophical justification for Hooker's taxonomic practice, and so he enthusiastically championed his friend.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Endersby, Jim -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1496-9. doi: 10.1126/science.1165915.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of History, University of Sussex, Falmer, Brighton BN1 9SH, UK. j.j.endersby@sussex.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20007893" target="_blank"〉PubMed〈/a〉

    Description: To understand the biology and evolution of ruminants, the cattle genome was sequenced to about sevenfold coverage. The cattle genome contains a minimum of 22,000 genes, with a core set of 14,345 orthologs shared among seven mammalian species of which 1217 are absent or undetected in noneutherian (marsupial or monotreme) genomes. Cattle-specific evolutionary breakpoint regions in chromosomes have a higher density of segmental duplications, enrichment of repetitive elements, and species-specific variations in genes associated with lactation and immune responsiveness. Genes involved in metabolism are generally highly conserved, although five metabolic genes are deleted or extensively diverged from their human orthologs. The cattle genome sequence thus provides a resource for understanding mammalian evolution and accelerating livestock genetic improvement for milk and meat production.〈br /〉〈br /〉〈a

    Description: The definitive mammalian middle ear (DMME) is defined by the loss of embryonic Meckel's cartilage and disconnection of the middle ear from the mandible in adults. It is a major feature distinguishing living mammals from nonmammalian vertebrates. We report a Cretaceous trechnotherian mammal with an ossified Meckel's cartilage in the adult, showing that homoplastic evolution of the DMME occurred in derived therian mammals, besides the known cases of eutriconodonts. The mandible with ossified Meckel's cartilage appears to be paedomorphic. Reabsorption of embryonic Meckel's cartilage to disconnect the ear ossicles from the mandible is patterned by a network of genes and signaling pathways. This fossil suggests that developmental heterochrony and gene patterning are major mechanisms in homplastic evolution of the DMME.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ji, Qiang -- Luo, Zhe-Xi -- Zhang, Xingliao -- Yuan, Chong-Xi -- Xu, Li -- New York, N.Y. -- Science. 2009 Oct 9;326(5950):278-81. doi: 10.1126/science.1178501.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Geology, Chinese Academy of Geological Sciences, Beijing 100037, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19815774" target="_blank"〉PubMed〈/a〉

    Description: The highly fragmented and distorted skull of the adult skeleton ARA-VP-6/500 includes most of the dentition and preserves substantial parts of the face, vault, and base. Anatomical comparisons and micro-computed tomography-based analysis of this and other remains reveal pre-Australopithecus hominid craniofacial morphology and structure. The Ardipithecus ramidus skull exhibits a small endocranial capacity (300 to 350 cubic centimeters), small cranial size relative to body size, considerable midfacial projection, and a lack of modern African ape-like extreme lower facial prognathism. Its short posterior cranial base differs from that of both Pan troglodytes and P. paniscus. Ar. ramidus lacks the broad, anteriorly situated zygomaxillary facial skeleton developed in later Australopithecus. This combination of features is apparently shared by Sahelanthropus, showing that the Mio-Pliocene hominid cranium differed substantially from those of both extant apes and Australopithecus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Suwa, Gen -- Asfaw, Berhane -- Kono, Reiko T -- Kubo, Daisuke -- Lovejoy, C Owen -- White, Tim D -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):68e1-7.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉University Museum, University of Tokyo, Hongo, Bunkyo-ku, Tokyo, 113-0033, Japan. suwa@um.u-tokyo.ac.jp〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810194" target="_blank"〉PubMed〈/a〉

    Description: Retroviruses can leave a "fossil record" in their hosts' genomes in the form of endogenous retroviruses. Foamy viruses, complex retroviruses that infect mammals, have been notably absent from this record. We have found an endogenous foamy virus within the genomes of sloths and show that foamy viruses were infecting mammals more than 100 million years ago and codiverged with their hosts across an entire geological era. Our analysis highlights the role of evolutionary constraint in maintaining viral genome structure and indicates that accessory genes and mammalian mechanisms of innate immunity are the products of macroevolutionary conflict played out over a geological time scale.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Katzourakis, Aris -- Gifford, Robert J -- Tristem, Michael -- Gilbert, M Thomas P -- Pybus, Oliver G -- New York, N.Y. -- Science. 2009 Sep 18;325(5947):1512. doi: 10.1126/science.1174149.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Zoology Department, University of Oxford, Oxford OX1 3PS, UK. aris.katzourakis@zoo.ox.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19762636" target="_blank"〉PubMed〈/a〉

    Description: Charles Darwin's theory of natural selection has been hailed as one of the most innovative contributions to modern science. When first proposed in 1859, however, it was widely rejected by his contemporaries, even by those who accepted the general idea of evolution. This article identifies those aspects of Darwin's work that led him to develop this revolutionary theory, including his studies of biogeography and animal breeding, and his recognition of the role played by the struggle for existence.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowler, Peter J -- New York, N.Y. -- Science. 2009 Jan 9;323(5911):223-6. doi: 10.1126/science.1160332.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉School of Philosophy and Anthropological Studies, Queen's University of Belfast, University Road Belfast, Belfast, Northern Ireland, BT7 1NN, UK. p.bowler@qub.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19131623" target="_blank"〉PubMed〈/a〉

    Description: Since Darwin, intergroup hostilities have figured prominently in explanations of the evolution of human social behavior. Yet whether ancestral humans were largely "peaceful" or "warlike" remains controversial. I ask a more precise question: If more cooperative groups were more likely to prevail in conflicts with other groups, was the level of intergroup violence sufficient to influence the evolution of human social behavior? Using a model of the evolutionary impact of between-group competition and a new data set that combines archaeological evidence on causes of death during the Late Pleistocene and early Holocene with ethnographic and historical reports on hunter-gatherer populations, I find that the estimated level of mortality in intergroup conflicts would have had substantial effects, allowing the proliferation of group-beneficial behaviors that were quite costly to the individual altruist.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bowles, Samuel -- New York, N.Y. -- Science. 2009 Jun 5;324(5932):1293-8. doi: 10.1126/science.1168112.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Santa Fe Institute, 1399 Hyde Park Road, Santa Fe, NM 87501, USA. samuel.bowles@gmail.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19498163" target="_blank"〉PubMed〈/a〉

    Description: Characterizing the evolutionary history of early dinosaurs is central to understanding their rise and diversification in the Late Triassic. However, fossils from basal lineages are rare. A new theropod dinosaur from New Mexico is a representative of the early North American diversification. Known from several nearly complete skeletons, it reveals a mosaic of plesiomorphic and derived features that clarify early saurischian dinosaur evolution and provide evidence for the antiquity of novel avian character systems including skeletal pneumaticity. The taxon further reveals latitudinal differences among saurischian assemblages during the Late Triassic, demonstrates that the theropod fauna from the Late Triassic of North America was not endemic, and suggests that intercontinental dispersal was prevalent during this time.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nesbitt, Sterling J -- Smith, Nathan D -- Irmis, Randall B -- Turner, Alan H -- Downs, Alex -- Norell, Mark A -- New York, N.Y. -- Science. 2009 Dec 11;326(5959):1530-3. doi: 10.1126/science.1180350.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Paleontology, American Museum of Natural History, New York, NY 10024, USA. nesbitt@jsg.utexas.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/20007898" target="_blank"〉PubMed〈/a〉

    Description: Referential models based on extant African apes have dominated reconstructions of early human evolution since Darwin's time. These models visualize fundamental human behaviors as intensifications of behaviors observed in living chimpanzees and/or gorillas (for instance, upright feeding, male dominance displays, tool use, culture, hunting, and warfare). Ardipithecus essentially falsifies such models, because extant apes are highly derived relative to our last common ancestors. Moreover, uniquely derived hominid characters, especially those of locomotion and canine reduction, appear to have emerged shortly after the hominid/chimpanzee divergence. Hence, Ardipithecus provides a new window through which to view our clade's earliest evolution and its ecological context. Early hominids and extant apes are remarkably divergent in many cardinal characters. We can no longer rely on homologies with African apes for accounts of our origins and must turn instead to general evolutionary theory. A proposed adaptive suite for the emergence of Ardipithecus from the last common ancestor that we shared with chimpanzees accounts for these principal ape/human differences, as well as the marked demographic success and cognitive efflorescence of later Plio-Pleistocene hominids.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lovejoy, C Owen -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):74e1-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, School of Biomedical Sciences, Kent State University, Kent, OH 44242-0001, USA. olovejoy@aol.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810200" target="_blank"〉PubMed〈/a〉

    Description: Species that are habitat specialists make up much of biodiversity, but the evolutionary factors that limit their distributions have rarely been considered. We show that in Drosophila, narrow and wide ranges of desiccation and cold resistance are closely associated with the distributions of specialist and generalist species, respectively. Furthermore, our data show that narrowly distributed tropical species consistently have low means and low genetic variation for these traits as compared with those of widely distributed species after phylogenetic correction. These results are unrelated to levels of neutral variation. Thus, specialist species may simply lack genetic variation in key traits, limiting their ability to adapt to conditions beyond their current range. We predict that such species are likely to be constrained in their evolutionary responses to future climate changes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kellermann, Vanessa -- van Heerwaarden, Belinda -- Sgro, Carla M -- Hoffmann, Ary A -- New York, N.Y. -- Science. 2009 Sep 4;325(5945):1244-6. doi: 10.1126/science.1175443.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Environmental Stress and Adaptation Research, Department of Genetics, University of Melbourne, Parkville, Melbourne 3010, Australia. vanessa.kellermann@biology.au.dk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19729654" target="_blank"〉PubMed〈/a〉

    Description: The Ardipithecus ramidus hand and wrist exhibit none of the derived mechanisms that restrict motion in extant great apes and are reminiscent of those of Miocene apes, such as Proconsul. The capitate head is more palmar than in all other known hominoids, permitting extreme midcarpal dorsiflexion. Ar. ramidus and all later hominids lack the carpometacarpal articular and ligamentous specializations of extant apes. Manual proportions are unlike those of any extant ape. Metacarpals 2 through 5 are relatively short, lacking any morphological traits associable with knuckle-walking. Humeral and ulnar characters are primitive and like those of later hominids. The Ar. ramidus forelimb complex implies palmigrady during bridging and careful climbing and exhibits none of the adaptations to vertical climbing, forelimb suspension, and knuckle-walking that are seen in extant African apes.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lovejoy, C Owen -- Simpson, Scott W -- White, Tim D -- Asfaw, Berhane -- Suwa, Gen -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):70e1-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, School of Biomedical Sciences, Kent State University, Kent, OH 44240-0001, USA. olovejoy@aol.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810196" target="_blank"〉PubMed〈/a〉

    Description: Genomic comparisons have established the chimpanzee and bonobo as our closest living relatives. However, the intricacies of gene regulation and expression caution against the use of these extant apes in deducing the anatomical structure of the last common ancestor that we shared with them. Evidence for this structure must therefore be sought from the fossil record. Until now, that record has provided few relevant data because available fossils were too recent or too incomplete. Evidence from Ardipithecus ramidus now suggests that the last common ancestor lacked the hand, foot, pelvic, vertebral, and limb structures and proportions specialized for suspension, vertical climbing, and knuckle-walking among extant African apes. If this hypothesis is correct, each extant African ape genus must have independently acquired these specializations from more generalized ancestors who still practiced careful arboreal climbing and bridging. African apes and hominids acquired advanced orthogrady in parallel. Hominoid spinal invagination is an embryogenetic mechanism that reoriented the shoulder girdle more laterally. It was unaccompanied by substantial lumbar spine abbreviation, an adaptation restricted to vertical climbing and/or suspension. The specialized locomotor anatomies and behaviors of chimpanzees and gorillas therefore constitute poor models for the origin and evolution of human bipedality.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lovejoy, C Owen -- Suwa, Gen -- Simpson, Scott W -- Matternes, Jay H -- White, Tim D -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):100-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anthropology, School of Biomedical Sciences, Kent State University, Kent, OH 44242-0001, USA. olovejoy@aol.com〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810199" target="_blank"〉PubMed〈/a〉

    Description: Ecological speciation is considered an adaptive response to selection for local adaptation. However, besides suitable ecological conditions, the process requires assortative mating to protect the nascent species from homogenization by gene flow. By means of a simple model, we demonstrate that disruptive ecological selection favors the evolution of sexual preferences for ornaments that signal local adaptation. Such preferences induce assortative mating with respect to ecological characters and enhance the strength of disruptive selection. Natural and sexual selection thus work in concert to achieve local adaptation and reproductive isolation, even in the presence of substantial gene flow. The resulting speciation process ensues without the divergence of mating preferences, avoiding problems that have plagued previous models of speciation by sexual selection.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van Doorn, G Sander -- Edelaar, Pim -- Weissing, Franz J -- New York, N.Y. -- Science. 2009 Dec 18;326(5960):1704-7. doi: 10.1126/science.1181661.

    Description: The presence of amber, the fossil form of the resins produced by many types of higher plants, has been reported from many localities in Mesozoic and Cenozoic rocks. We have found Class I (polylabdanoid) amber in Carboniferous sediments dating to approximately 320 million years ago. This result demonstrates that preconifer gymnosperms evolved the biosynthetic mechanisms to produce complex polyterpenoid resins earlier than previously believed and that the biosynthetic pathways leading to the types of polylabdanoid resins that are now typically found in conifers and those now typically found in angiosperms had already diverged by the Carboniferous.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bray, P Sargent -- Anderson, Ken B -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):132-4. doi: 10.1126/science.1177539.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geology, Southern Illinois University Carbondale, Carbondale, IL 62901, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19797659" target="_blank"〉PubMed〈/a〉

    Description: Environmental change, including climate change, can cause rapid phenotypic change via both ecological and evolutionary processes. Because ecological and evolutionary dynamics are intimately linked, a major challenge is to identify their relative roles. We exactly decomposed the change in mean body weight in a free-living population of Soay sheep into all the processes that contribute to change. Ecological processes contribute most, with selection--the underpinning of adaptive evolution--explaining little of the observed phenotypic trend. Our results enable us to explain why selection has so little effect even though weight is heritable, and why environmental change has caused a decline in the body size of Soay sheep.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ozgul, Arpat -- Tuljapurkar, Shripad -- Benton, Tim G -- Pemberton, Josephine M -- Clutton-Brock, Tim H -- Coulson, Tim -- P01 AG022500/AG/NIA NIH HHS/ -- P01/AG/22500/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2009 Jul 24;325(5939):464-7. doi: 10.1126/science.1173668.

    Description: Nearly all of the large-bodied predators (〉2.5 tons) on northern continents during the Late Cretaceous were tyrannosaurid dinosaurs. We show that their most conspicuous functional specializations--a proportionately large skull, incisiform premaxillary teeth, expanded jaw-closing musculature, diminutive forelimbs, and hindlimbs with cursorial proportions--were present in a new, small-bodied, basal tyrannosauroid from Lower Cretaceous rocks in northeastern China. These specializations, which were later scaled up in Late Cretaceous tyrannosaurids with body masses approaching 100 times greater, drove the most dominant radiation of macropredators of the Mesozoic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sereno, Paul C -- Tan, Lin -- Brusatte, Stephen L -- Kriegstein, Henry J -- Zhao, Xijin -- Cloward, Karen -- New York, N.Y. -- Science. 2009 Oct 16;326(5951):418-22. doi: 10.1126/science.1177428.

    Description: As perceived by Darwin, evolutionary adaptation by the processes of mutation and selection is difficult to understand for complex features that are the product of numerous traits acting in concert, for example the eye or the apparatus of flight. Typically, mutations simultaneously affect multiple phenotypic characters. This phenomenon is known as pleiotropy. The impact of pleiotropy on evolution has for decades been the subject of formal analysis. Some authors have suggested that pleiotropy can impede evolutionary progress (a so-called 'cost of complexity'). The plausibility of various phenomena attributed to pleiotropy depends on how many traits are affected by each mutation and on our understanding of the correlation between the number of traits affected by each gene substitution and the size of mutational effects on individual traits. Here we show, by studying pleiotropy in mice with the use of quantitative trait loci (QTLs) affecting skeletal characters, that most QTLs affect a relatively small subset of traits and that a substitution at a QTL has an effect on each trait that increases with the total number of traits affected. This suggests that evolution of higher organisms does not suffer a 'cost of complexity' because most mutations affect few traits and the size of the effects does not decrease with pleiotropy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wagner, Gunter P -- Kenney-Hunt, Jane P -- Pavlicev, Mihaela -- Peck, Joel R -- Waxman, David -- Cheverud, James M -- England -- Nature. 2008 Mar 27;452(7186):470-2. doi: 10.1038/nature06756.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, Yale University, New Haven, Connecticut 06520-8106, USA. gunter.wagner@yale.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18368117" target="_blank"〉PubMed〈/a〉

    Description: Biosignatures and structures in the geological record indicate that microbial life has inhabited Earth for the past 3.5 billion years or so. Research in the physical sciences has been able to generate statements about the ancient environment that hosted this life. These include the chemical compositions and temperatures of the early ocean and atmosphere. Only recently have the natural sciences been able to provide experimental results describing the environments of ancient life. Our previous work with resurrected proteins indicated that ancient life lived in a hot environment. Here we expand the timescale of resurrected proteins to provide a palaeotemperature trend of the environments that hosted life from 3.5 to 0.5 billion years ago. The thermostability of more than 25 phylogenetically dispersed ancestral elongation factors suggest that the environment supporting ancient life cooled progressively by 30 degrees C during that period. Here we show that our results are robust to potential statistical bias associated with the posterior distribution of inferred character states, phylogenetic ambiguity, and uncertainties in the amino-acid equilibrium frequencies used by evolutionary models. Our results are further supported by a nearly identical cooling trend for the ancient ocean as inferred from the deposition of oxygen isotopes. The convergence of results from natural and physical sciences suggest that ancient life has continually adapted to changes in environmental temperatures throughout its evolutionary history.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Gaucher, Eric A -- Govindarajan, Sridhar -- Ganesh, Omjoy K -- England -- Nature. 2008 Feb 7;451(7179):704-7. doi: 10.1038/nature06510.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Foundation for Applied Molecular Evolution, Gainesville, Florida 32601, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18256669" target="_blank"〉PubMed〈/a〉

    Description: Bats (Chiroptera) represent one of the largest and most diverse radiations of mammals, accounting for one-fifth of extant species. Although recent studies unambiguously support bat monophyly and consensus is rapidly emerging about evolutionary relationships among extant lineages, the fossil record of bats extends over 50 million years, and early evolution of the group remains poorly understood. Here we describe a new bat from the Early Eocene Green River Formation of Wyoming, USA, with features that are more primitive than seen in any previously known bat. The evolutionary pathways that led to flapping flight and echolocation in bats have been in dispute, and until now fossils have been of limited use in documenting transitions involved in this marked change in lifestyle. Phylogenetically informed comparisons of the new taxon with other bats and non-flying mammals reveal that critical morphological and functional changes evolved incrementally. Forelimb anatomy indicates that the new bat was capable of powered flight like other Eocene bats, but ear morphology suggests that it lacked their echolocation abilities, supporting a 'flight first' hypothesis for chiropteran evolution. The shape of the wings suggests that an undulating gliding-fluttering flight style may be primitive for bats, and the presence of a long calcar indicates that a broad tail membrane evolved early in Chiroptera, probably functioning as an additional airfoil rather than as a prey-capture device. Limb proportions and retention of claws on all digits indicate that the new bat may have been an agile climber that employed quadrupedal locomotion and under-branch hanging behaviour.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simmons, Nancy B -- Seymour, Kevin L -- Habersetzer, Jorg -- Gunnell, Gregg F -- England -- Nature. 2008 Feb 14;451(7180):818-21. doi: 10.1038/nature06549.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉American Museum of Natural History, Central Park West at 79th Street, New York, New York 10024, USA. simmons@amnh.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18270539" target="_blank"〉PubMed〈/a〉

    Description: The evolution of animal personalities is a topic of primary importance in behavioural ecology. An intriguing empirical fact is the consistency of animal responses to repeated stresses or threats. Wolf et al. propose an evolutionary model to explain the emergence of consistent personalities. They show that a population dimorphism for an exploration trait implies the existence of behavioural syndromes, such as decreased aggressiveness and the boldness of 'thorough explorers'. This finding helps explain how animal responses can be consistent, despite the seeming advantages of flexible responses. However, we contend that the emergence of a dimorphism depends critically on the intensity of the trade-off between exploration investment and first-year fecundity.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Massol, Francois -- Crochet, Pierre-Andre -- England -- Nature. 2008 Feb 28;451(7182):E8-9; discussion E9-10. doi: 10.1038/nature06743.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉UMR 5175 CEFE-Centre d'Ecologie Fonctionnelle et Evolutive (CNRS), 1919 Route de Mende, F-34293 Montpellier cedex 05, France. francois.massol@cefe.cnrs.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18305490" target="_blank"〉PubMed〈/a〉

    Description: One of the identifying characteristics of tetrapods (limbed vertebrates) is the presence of fingers and toes. Whereas the proximal part of the tetrapod limb skeleton can easily be homologized with the paired fin skeletons of sarcopterygian (lobe-finned) fish, there has been much debate about the origin of digits. Early hypotheses interpreted digits as derivatives of fin radials, but during the 1990s the idea gained acceptance that digits are evolutionary novelties without direct equivalents in fish fin skeletons. This was partly based on developmental genetic data, but also substantially on the pectoral fin skeleton of the elpistostegid (transitional fish/tetrapod) Panderichthys, which appeared to lack distal digit-like radials. Here we present a CT scan study of an undisturbed pectoral fin of Panderichthys demonstrating that the plate-like 'ulnare' of previous reconstructions is an artefact and that distal radials are in fact present. This distal portion is more tetrapod-like than that found in Tiktaalik and, in combination with new data about fin development in basal actinopterygians, sharks and lungfish, makes a strong case for fingers not being a novelty of tetrapods but derived from pre-existing distal radials present in all sarcopterygian fish.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Boisvert, Catherine A -- Mark-Kurik, Elga -- Ahlberg, Per E -- England -- Nature. 2008 Dec 4;456(7222):636-8. doi: 10.1038/nature07339.

    Description: The evolution of oxygenic photosynthesis had a profound impact on the Earth's surface chemistry, leading to a sharp rise in atmospheric oxygen between 2.45 and 2.32 billion years (Gyr) ago and the onset of extreme ice ages. The oldest widely accepted evidence for oxygenic photosynthesis has come from hydrocarbons extracted from approximately 2.7-Gyr-old shales in the Pilbara Craton, Australia, which contain traces of biomarkers (molecular fossils) indicative of eukaryotes and suggestive of oxygen-producing cyanobacteria. The soluble hydrocarbons were interpreted to be indigenous and syngenetic despite metamorphic alteration and extreme enrichment (10-20 per thousand) of (13)C relative to bulk sedimentary organic matter. Here we present micrometre-scale, in situ (13)C/(12)C measurements of pyrobitumen (thermally altered petroleum) and kerogen from these metamorphosed shales, including samples that originally yielded biomarkers. Our results show that both kerogen and pyrobitumen are strongly depleted in (13)C, indicating that indigenous petroleum is 10-20 per thousand lighter than the extracted hydrocarbons. These results are inconsistent with an indigenous origin for the biomarkers. Whatever their origin, the biomarkers must have entered the rock after peak metamorphism approximately 2.2 Gyr ago and thus do not provide evidence for the existence of eukaryotes and cyanobacteria in the Archaean eon. The oldest fossil evidence for eukaryotes and cyanobacteria therefore reverts to 1.78-1.68 Gyr ago and approximately 2.15 Gyr ago, respectively. Our results eliminate the evidence for oxygenic photosynthesis approximately 2.7 Gyr ago and exclude previous biomarker evidence for a long delay (approximately 300 million years) between the appearance of oxygen-producing cyanobacteria and the rise in atmospheric oxygen 2.45-2.32 Gyr ago.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rasmussen, Birger -- Fletcher, Ian R -- Brocks, Jochen J -- Kilburn, Matt R -- England -- Nature. 2008 Oct 23;455(7216):1101-4. doi: 10.1038/nature07381.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Applied Geology, Curtin University of Technology, Kent Street, Bentley, Western Australia 6102, Australia.

    Description: Explaining the rise and maintenance of cooperation is central to our understanding of biological systems and human societies. When an individual's cooperativeness is used by other individuals as a choice criterion, there can be competition to be more generous than others, a situation called competitive altruism. The evolution of cooperation between non-relatives can then be driven by a positive feedback between increasing levels of cooperativeness and choosiness. Here we use evolutionary simulations to show that, in a situation where individuals have the opportunity to engage in repeated pairwise interactions, the equilibrium degree of cooperativeness depends critically on the amount of behavioural variation that is being maintained in the population by processes such as mutation. Because our model does not invoke complex mechanisms such as negotiation behaviour, it can be applied to a wide range of species. The results suggest an important role of lifespan in the evolution of cooperation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉McNamara, John M -- Barta, Zoltan -- Fromhage, Lutz -- Houston, Alasdair I -- England -- Nature. 2008 Jan 10;451(7175):189-92. doi: 10.1038/nature06455.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Mathematics, University of Bristol, University Walk, Bristol BS8 1TW, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18185587" target="_blank"〉PubMed〈/a〉

    Description: Malaria parasites and related Apicomplexans are the causative agents of the some of the most serious infectious diseases of humans, companion animals, livestock and wildlife. These parasites must undergo sexual reproduction to transmit from vertebrate hosts to vectors, and their sex ratios are consistently female-biased. Sex allocation theory, a cornerstone of evolutionary biology, is remarkably successful at explaining female-biased sex ratios in multicellular taxa, but has proved controversial when applied to malaria parasites. Here we show that, as predicted by theory, sex ratio is an important fitness-determining trait and Plasmodium chabaudi parasites adjust their sex allocation in response to the presence of unrelated conspecifics. This suggests that P. chabaudi parasites use kin discrimination to evaluate the genetic diversity of their infections, and they adjust their behaviour in response to environmental cues. Malaria parasites provide a novel way to test evolutionary theory, and support the generality and power of a darwinian approach.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3807728/" 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/PMC3807728/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Reece, Sarah E -- Drew, Damien R -- Gardner, Andy -- Biotechnology and Biological Sciences Research Council/United Kingdom -- Wellcome Trust/United Kingdom -- England -- Nature. 2008 May 29;453(7195):609-14. doi: 10.1038/nature06954.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Evolutionary Biology, Ashworth Laboratories, School of Biological Science, University of Edinburgh, West Mains Road, Edinburgh EH9 3JT, UK. sarah.reece@ed.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18509435" target="_blank"〉PubMed〈/a〉

    Description: The evolution of avian flight remains one of biology's major controversies, with a long history of functional interpretations of fossil forms given as evidence for either an arboreal or cursorial origin of flight. Despite repeated emphasis on the 'wing-stroke' as a necessary avenue of investigation for addressing the evolution of flight, no empirical data exist on wing-stroke dynamics in an experimental evolutionary context. Here we present the first comparison of wing-stroke kinematics of the primary locomotor modes (descending flight and incline flap-running) that lead to level-flapping flight in juvenile ground birds throughout development. We offer results that are contrary both to popular perception and inferences from other studies. Starting shortly after hatching and continuing through adulthood, ground birds use a wing-stroke confined to a narrow range of less than 20 degrees , when referenced to gravity, that directs aerodynamic forces about 40 degrees above horizontal, permitting a 180 degrees range in the direction of travel. Based on our results, we put forth an ontogenetic-transitional wing hypothesis that posits that the incremental adaptive stages leading to the evolution of avian flight correspond behaviourally and morphologically to transitional stages observed in ontogenetic forms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Dial, Kenneth P -- Jackson, Brandon E -- Segre, Paolo -- England -- Nature. 2008 Feb 21;451(7181):985-9. doi: 10.1038/nature06517.

    Description: Among the morphological changes that occurred during the 'fish-to-tetrapod' transition was a marked reorganization of the cranial endoskeleton. Details of this transition, including the sequence of character acquisition, have not been evident from the fossil record. Here we describe the braincase, palatoquadrate and branchial skeleton of Tiktaalik roseae, the Late Devonian sarcopterygian fish most closely related to tetrapods. Although retaining a primitive configuration in many respects, the cranial endoskeleton of T. roseae shares derived features with tetrapods such as a large basal articulation and a flat, horizontally oriented entopterygoid. Other features in T. roseae, like the short, straight hyomandibula, show morphology intermediate between the condition observed in more primitive fish and that observed in tetrapods. The combination of characters in T. roseae helps to resolve the relative timing of modifications in the cranial endoskeleton. The sequence of modifications suggests changes in head mobility and intracranial kinesis that have ramifications for the origin of vertebrate terrestriality.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Downs, Jason P -- Daeschler, Edward B -- Jenkins, Farish A Jr -- Shubin, Neil H -- England -- Nature. 2008 Oct 16;455(7215):925-9. doi: 10.1038/nature07189.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Academy of Natural Sciences of Philadelphia, 1900 Benjamin Franklin Parkway, Philadelphia, Pennsylvania 19103, USA. downs@ansp.org〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18923515" target="_blank"〉PubMed〈/a〉

    Description: The gap in our understanding of the evolutionary transition from fish to tetrapod is beginning to close thanks to the discovery of new intermediate forms such as Tiktaalik roseae. Here we narrow it further by presenting the skull, exceptionally preserved braincase, shoulder girdle and partial pelvis of Ventastega curonica from the Late Devonian of Latvia, a transitional intermediate form between the 'elpistostegids' Panderichthys and Tiktaalik and the Devonian tetrapods (limbed vertebrates) Acanthostega and Ichthyostega. Ventastega is the most primitive Devonian tetrapod represented by extensive remains, and casts light on a part of the phylogeny otherwise only represented by fragmentary taxa: it illuminates the origin of principal tetrapod structures and the extent of morphological diversity among the transitional forms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ahlberg, Per E -- Clack, Jennifer A -- Luksevics, Ervins -- Blom, Henning -- Zupins, Ivars -- England -- Nature. 2008 Jun 26;453(7199):1199-204. doi: 10.1038/nature06991.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Subdepartment of Evolutionary Organismal Biology, Department of Physiology and Developmental Biology, Uppsala University, Norbyvagen 18A, 752 36 Uppsala, Sweden. per.ahlberg@ebc.uu.se〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18580942" target="_blank"〉PubMed〈/a〉
