Description: North Africa is a key region for understanding human history, but the genetic history of its people is largely unknown. We present genomic data from seven 15,000-year-old modern humans, attributed to the Iberomaurusian culture, from Morocco. We find a genetic affinity with early Holocene Near Easterners, best represented by Levantine Natufians, suggesting a pre-agricultural connection between Africa and the Near East. We do not find evidence for gene flow from Paleolithic Europeans to Late Pleistocene North Africans. The Taforalt individuals derive one-third of their ancestry from sub-Saharan Africans, best approximated by a mixture of genetic components preserved in present-day West and East Africans. Thus, we provide direct evidence for genetic interactions between modern humans across Africa and Eurasia in the Pleistocene.

Description: The contribution of rare and low-frequency variants to human traits is largely unexplored. Here we describe insights from sequencing whole genomes (low read depth, 7x) or exomes (high read depth, 80x) of nearly 10,000 individuals from population-based and disease collections. In extensively phenotyped cohorts we characterize over 24 million novel sequence variants, generate a highly accurate imputation reference panel and identify novel alleles associated with levels of triglycerides (APOB), adiponectin (ADIPOQ) and low-density lipoprotein cholesterol (LDLR and RGAG1) from single-marker and rare variant aggregation tests. We describe population structure and functional annotation of rare and low-frequency variants, use the data to estimate the benefits of sequencing for association studies, and summarize lessons from disease-specific collections. Finally, we make available an extensive resource, including individual-level genetic and phenotypic data and web-based tools to facilitate the exploration of association results.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4773891/" 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/PMC4773891/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉UK10K Consortium -- Walter, Klaudia -- Min, Josine L -- Huang, Jie -- Crooks, Lucy -- Memari, Yasin -- McCarthy, Shane -- Perry, John R B -- Xu, ChangJiang -- Futema, Marta -- Lawson, Daniel -- Iotchkova, Valentina -- Schiffels, Stephan -- Hendricks, Audrey E -- Danecek, Petr -- Li, Rui -- Floyd, James -- Wain, Louise V -- Barroso, Ines -- Humphries, Steve E -- Hurles, Matthew E -- Zeggini, Eleftheria -- Barrett, Jeffrey C -- Plagnol, Vincent -- Richards, J Brent -- Greenwood, Celia M T -- Timpson, Nicholas J -- Durbin, Richard -- Soranzo, Nicole -- 091551/Wellcome Trust/United Kingdom -- 095515/Wellcome Trust/United Kingdom -- 095564/Wellcome Trust/United Kingdom -- 098498/Wellcome Trust/United Kingdom -- 100140/Wellcome Trust/United Kingdom -- 104036/Wellcome Trust/United Kingdom -- CZD/16/6/4/Chief Scientist Office/United Kingdom -- MC_UU_12013/3/Medical Research Council/United Kingdom -- RG/10/13/28570/British Heart Foundation/United Kingdom -- WT091310/Wellcome Trust/United Kingdom -- England -- Nature. 2015 Oct 1;526(7571):82-90. doi: 10.1038/nature14962.

Description: The genomic causes and effects of divergent ecological selection during speciation are still poorly understood. Here we report the discovery and detailed characterization of early-stage adaptive divergence of two cichlid fish ecomorphs in a small (700 meters in diameter) isolated crater lake in Tanzania. The ecomorphs differ in depth preference, male breeding color, body shape, diet, and trophic morphology. With whole-genome sequences of 146 fish, we identified 98 clearly demarcated genomic "islands" of high differentiation and demonstrated the association of genotypes across these islands with divergent mate preferences. The islands contain candidate adaptive genes enriched for functions in sensory perception (including rhodopsin and other twilight-vision-associated genes), hormone signaling, and morphogenesis. Our study suggests mechanisms and genomic regions that may play a role in the closely related mega-radiation of Lake Malawi.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4700518/" 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/PMC4700518/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Malinsky, Milan -- Challis, Richard J -- Tyers, Alexandra M -- Schiffels, Stephan -- Terai, Yohey -- Ngatunga, Benjamin P -- Miska, Eric A -- Durbin, Richard -- Genner, Martin J -- Turner, George F -- 097677/Z/11/Z/Wellcome Trust/United Kingdom -- WT098051/Wellcome Trust/United Kingdom -- Cancer Research UK/United Kingdom -- New York, N.Y. -- Science. 2015 Dec 18;350(6267):1493-8. doi: 10.1126/science.aac9927.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Wellcome Trust Sanger Institute, Cambridge CB10 1SA, UK.

Description: How and when the Americas were populated remains contentious. Using ancient and modern genome-wide data, we found that the ancestors of all present-day Native Americans, including Athabascans and Amerindians, entered the Americas as a single migration wave from Siberia no earlier than 23 thousand years ago (ka) and after no more than an 8000-year isolation period in Beringia. After their arrival to the Americas, ancestral Native Americans diversified into two basal genetic branches around 13 ka, one that is now dispersed across North and South America and the other restricted to North America. Subsequent gene flow resulted in some Native Americans sharing ancestry with present-day East Asians (including Siberians) and, more distantly, Australo-Melanesians. Putative "Paleoamerican" relict populations, including the historical Mexican Pericues and South American Fuego-Patagonians, are not directly related to modern Australo-Melanesians as suggested by the Paleoamerican Model.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4733658/" 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/PMC4733658/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Raghavan, Maanasa -- Steinrucken, Matthias -- Harris, Kelley -- Schiffels, Stephan -- Rasmussen, Simon -- DeGiorgio, Michael -- Albrechtsen, Anders -- Valdiosera, Cristina -- Avila-Arcos, Maria C -- Malaspinas, Anna-Sapfo -- Eriksson, Anders -- Moltke, Ida -- Metspalu, Mait -- Homburger, Julian R -- Wall, Jeff -- Cornejo, Omar E -- Moreno-Mayar, J Victor -- Korneliussen, Thorfinn S -- Pierre, Tracey -- Rasmussen, Morten -- Campos, Paula F -- Damgaard, Peter de Barros -- Allentoft, Morten E -- Lindo, John -- Metspalu, Ene -- Rodriguez-Varela, Ricardo -- Mansilla, Josefina -- Henrickson, Celeste -- Seguin-Orlando, Andaine -- Malmstrom, Helena -- Stafford, Thomas Jr -- Shringarpure, Suyash S -- Moreno-Estrada, Andres -- Karmin, Monika -- Tambets, Kristiina -- Bergstrom, Anders -- Xue, Yali -- Warmuth, Vera -- Friend, Andrew D -- Singarayer, Joy -- Valdes, Paul -- Balloux, Francois -- Leboreiro, Ilan -- Vera, Jose Luis -- Rangel-Villalobos, Hector -- Pettener, Davide -- Luiselli, Donata -- Davis, Loren G -- Heyer, Evelyne -- Zollikofer, Christoph P E -- Ponce de Leon, Marcia S -- Smith, Colin I -- Grimes, Vaughan -- Pike, Kelly-Anne -- Deal, Michael -- Fuller, Benjamin T -- Arriaza, Bernardo -- Standen, Vivien -- Luz, Maria F -- Ricaut, Francois -- Guidon, Niede -- Osipova, Ludmila -- Voevoda, Mikhail I -- Posukh, Olga L -- Balanovsky, Oleg -- Lavryashina, Maria -- Bogunov, Yuri -- Khusnutdinova, Elza -- Gubina, Marina -- Balanovska, Elena -- Fedorova, Sardana -- Litvinov, Sergey -- Malyarchuk, Boris -- Derenko, Miroslava -- Mosher, M J -- Archer, David -- Cybulski, Jerome -- Petzelt, Barbara -- Mitchell, Joycelynn -- Worl, Rosita -- Norman, Paul J -- Parham, Peter -- Kemp, Brian M -- Kivisild, Toomas -- Tyler-Smith, Chris -- Sandhu, Manjinder S -- Crawford, Michael -- Villems, Richard -- Smith, David Glenn -- Waters, Michael R -- Goebel, Ted -- Johnson, John R -- Malhi, Ripan S -- Jakobsson, Mattias -- Meltzer, David J -- Manica, Andrea -- Durbin, Richard -- Bustamante, Carlos D -- Song, Yun S -- Nielsen, Rasmus -- Willerslev, Eske -- 098051/Wellcome Trust/United Kingdom -- 261213/European Research Council/International -- 2R01HG003229-09/HG/NHGRI NIH HHS/ -- BB/H005854/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- R01-AI17892/AI/NIAID NIH HHS/ -- R01-GM094402/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2015 Aug 21;349(6250):aab3884. doi: 10.1126/science.aab3884.

Description: Modern humans arrived in Europe ~45,000 years ago, but little is known about their genetic composition before the start of farming ~8,500 years ago. Here we analyse genome-wide data from 51 Eurasians from ~45,000-7,000 years ago. Over this time, the proportion of Neanderthal DNA decreased from 3-6% to around 2%, consistent with natural selection against Neanderthal variants in modern humans. Whereas there is no evidence of the earliest modern humans in Europe contributing to the genetic composition of present-day Europeans, all individuals between ~37,000 and ~14,000 years ago descended from a single founder population which forms part of the ancestry of present-day Europeans. An ~35,000-year-old individual from northwest Europe represents an early branch of this founder population which was then displaced across a broad region, before reappearing in southwest Europe at the height of the last Ice Age ~19,000 years ago. During the major warming period after ~14,000 years ago, a genetic component related to present-day Near Easterners became widespread in Europe. These results document how population turnover and migration have been recurring themes of European prehistory.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Fu, Qiaomei -- Posth, Cosimo -- Hajdinjak, Mateja -- Petr, Martin -- Mallick, Swapan -- Fernandes, Daniel -- Furtwangler, Anja -- Haak, Wolfgang -- Meyer, Matthias -- Mittnik, Alissa -- Nickel, Birgit -- Peltzer, Alexander -- Rohland, Nadin -- Slon, Viviane -- Talamo, Sahra -- Lazaridis, Iosif -- Lipson, Mark -- Mathieson, Iain -- Schiffels, Stephan -- Skoglund, Pontus -- Derevianko, Anatoly P -- Drozdov, Nikolai -- Slavinsky, Vyacheslav -- Tsybankov, Alexander -- Cremonesi, Renata Grifoni -- Mallegni, Francesco -- Gely, Bernard -- Vacca, Eligio -- Morales, Manuel R Gonzalez -- Straus, Lawrence G -- Neugebauer-Maresch, Christine -- Teschler-Nicola, Maria -- Constantin, Silviu -- Moldovan, Oana Teodora -- Benazzi, Stefano -- Peresani, Marco -- Coppola, Donato -- Lari, Martina -- Ricci, Stefano -- Ronchitelli, Annamaria -- Valentin, Frederique -- Thevenet, Corinne -- Wehrberger, Kurt -- Grigorescu, Dan -- Rougier, Helene -- Crevecoeur, Isabelle -- Flas, Damien -- Semal, Patrick -- Mannino, Marcello A -- Cupillard, Christophe -- Bocherens, Herve -- Conard, Nicholas J -- Harvati, Katerina -- Moiseyev, Vyacheslav -- Drucker, Dorothee G -- Svoboda, Jiri -- Richards, Michael P -- Caramelli, David -- Pinhasi, Ron -- Kelso, Janet -- Patterson, Nick -- Krause, Johannes -- Paabo, Svante -- Reich, David -- Nature. 2016 May 2. doi: 10.1038/nature17993.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Key Laboratory of Vertebrate Evolution and Human Origins of Chinese Academy of Sciences, IVPP, CAS, Beijing 100044, China. ; Department of Genetics, Harvard Medical School, Boston, Massachusetts 02115, USA. ; Department of Evolutionary Genetics, Max Planck Institute for Evolutionary Anthropology, 04103 Leipzig, Germany. ; Institute for Archaeological Sciences, Archaeo- and Palaeogenetics, University of Tubingen, 72070 Tubingen, Germany. ; Department of Archaeogenetics, Max Planck Institute for the Science of Human History, 07745 Jena, Germany. ; Broad Institute of MIT and Harvard, Cambridge, Massachusetts 02142, USA. ; Howard Hughes Medical Institute, Harvard Medical School, Boston, Massachusetts 02115, USA. ; School of Archaeology and Earth Institute, University College Dublin, Belfield, Dublin 4, Ireland. ; CIAS, Department of Life Sciences, University of Coimbra, 3000-456 Coimbra, Portugal. ; Australian Centre for Ancient DNA, School of Biological Sciences, The University of Adelaide, SA-5005 Adelaide, Australia. ; Department of Human Evolution, Max Planck Institute for Evolutionary Anthropology, 04103 Leipzig, Germany. ; Institute of Archaeology and Ethnography, Russian Academy of Sciences, Siberian Branch, 17 Novosibirsk, RU-630090, Russia. ; Altai State University, Barnaul, RU-656049, Russia. ; Dipartimento di Civilta e Forme del Sapere, Universita di Pisa, 56126 Pisa, Italy. ; Department of Biology, University of Pisa, 56126 Pisa, Italy. ; Direction regionale des affaires culturelles Rhone-Alpes, 69283 Lyon, Cedex 01, France. ; Dipartimento di Biologia, Universita degli Studi di Bari 'Aldo Moro', 70125 Bari, Italy. ; Instituto Internacional de Investigaciones Prehistoricas, Universidad de Cantabria, 39005 Santander, Spain. ; Department of Anthropology, MSC01 1040, University of New Mexico, Albuquerque, New Mexico 87131-0001, USA. ; Quaternary Archaeology, Institute for Oriental and European Archaeology, Austrian Academy of Sciences, 1010 Vienna, Austria. ; Department of Anthropology, Natural History Museum Vienna, 1010 Vienna, Austria. ; Department of Anthropology, University of Vienna, 1090 Vienna, Austria. ; "Emil Racovita" Institute of Speleology, 010986 Bucharest 12, Romania. ; "Emil Racovita" Institute of Speleology, Cluj Branch, 400006 Cluj, Romania. ; Department of Cultural Heritage, University of Bologna, 48121 Ravenna, Italy. ; Sezione di Scienze Preistoriche e Antropologiche, Dipartimento di Studi Umanistici, Universita di Ferrara, 44100 Ferrara, Italy. ; Universita degli Studi di Bari 'Aldo Moro', 70125 Bari, Italy. ; Museo di "Civilta preclassiche della Murgia meridionale", 72017 Ostuni, Italy. ; Dipartimento di Biologia, Universita di Firenze, 50122 Florence, Italy. ; Dipartimento di Scienze Fisiche, della Terra e dell'Ambiente, U.R.

Description: When selection is acting on a large genetically diverse population, beneficial alleles increase in frequency. This fact can be used to map quantitative trait loci by sequencing the pooled DNA from the population at consecutive time points and observing allele frequency changes. Here, we present a population genetic method to analyze time series data of allele frequencies from such an experiment. Beginning with a range of proposed evolutionary scenarios, the method measures the consistency of each with the observed frequency changes. Evolutionary theory is utilized to formulate equations of motion for the allele frequencies, following which likelihoods for having observed the sequencing data under each scenario are derived. Comparison of these likelihoods gives an insight into the prevailing dynamics of the system under study. We illustrate the method by quantifying selective effects from an experiment, in which two phenotypically different yeast strains were first crossed and then propagated under heat stress (Parts L, Cubillos FA, Warringer J, et al. [14 co-authors]. 2011. Revealing the genetic structure of a trait by sequencing a population under selection. Genome Res ). From these data, we discover that about 6% of polymorphic sites evolve nonneutrally under heat stress conditions, either because of their linkage to beneficial (driver) alleles or because they are drivers themselves. We further identify 44 genomic regions containing one or more candidate driver alleles, quantify their apparent selective advantage, obtain estimates of recombination rates within the regions, and show that the dynamics of the drivers display a strong signature of selection going beyond additive models. Our approach is applicable to study adaptation in a range of systems under different evolutionary pressures.

Description: Some recent academic and popular literature implies that the problem of the colonization of the Americas has been largely resolved in favor of one specific model: a Pacific coastal migration, dependent on high marine productivity, from the Bering Strait to South America, thousands of years before Clovis, the earliest widespread cultural manifestation south of the glacial ice. Speculations on maritime adaptations and typological links (stemmed points) across thousands of kilometers have also been advanced. A review of the current genetic, archeological, and paleoecological evidence indicates that ancestral Native American population expansion occurred after 16,000 years ago, consistent with the archeological record, particularly with the earliest securely dated sites after ~15,000 years ago. These data are largely consistent with either an inland (ice-free corridor) or Pacific coastal routes (or both), but neither can be rejected at present. Systematic archeological and paleoecological investigations, informed by geomorphology, are required to test each hypothesis.
