  • The Simons Genome Diversity Project

    Open AccessSwapan Mallick, Heng Li et al.ARTICLENature2016

    Here we report the Simons Genome Diversity Project data set: high quality genomes from 300 individuals from 142 diverse populations. These genomes include at least 5.8 million base pairs that are not present in the human reference genome. Our analysis reveals key features of the landscape of human genome variation, including that the rate of accumulation of mutations has accelerated by about 5% in non-Africans compared to Africans since divergenc…

  • Genomic evidence for the Pleistocene and recent population history of Native Americans

    Open AccessMaanasa Raghavan, Matthias Steinrücken et al.ARTICLEScience2015

    Genetic history of Native Americans Several theories have been put forth as to the origin and timing of when Native American ancestors entered the Americas. To clarify this controversy, Raghavan et al. examined the genomic variation among ancient and modern individuals from Asia and the Americas. There is no evidence for multiple waves of entry or recurrent gene flow with Asians in northern populations. The earliest migrations occurred no earlier…

  • Ancient human genomes suggest three ancestral populations for present-day Europeans

  • The genetic prehistory of the New World Arctic

    Open AccessMaanasa Raghavan, Michael Degiorgio et al.ARTICLEScience2014

    Arctic genetics comes in from the cold Despite a well-characterized archaeological record, the genetics of the people who inhabit the Arctic have been unexplored. Raghavan et al. sequenced ancient and modern genomes of individuals from the North American Arctic (see the Perspective by Park). Analyses of these genomes indicate that the Arctic was colonized 6000 years ago by a migration separate from the one that gave rise to other Native American …

  • Upper Palaeolithic Siberian genome reveals dual ancestry of Native Americans

  • No Evidence from Genome-wide Data of a Khazar Origin for the Ashkenazi Jews

    Doron M Behar, Mait Metspalu et al.ARTICLEHuman Biology2013

    The origin and history of the Ashkenazi Jewish population have long been of great interest, and advances in high-throughput genetic analysis have recently provided a new approach for investigating these topics. We and others have argued on the basis of genome-wide data that the Ashkenazi Jewish population derives its ancestry from a combination of sources tracing to both Europe and the Middle East. It has been claimed, however, through a reanalys…

  • Evolution of the Pygmy Phenotype

    Andrea Bamberg Migliano, Andrea Bamberg Migliano Andrea Bamberg Migliano et al.ARTICLEHuman Biology2013Citada por: 27Referências: 88

    Human pygmy populations inhabit different regions of the world, from Africa to Melanesia. In Asia, short-statured populations are often referred to as "negritos." Their short stature has been interpreted as a consequence of thermoregulatory, nutritional, and/or locomotory adaptations to life in tropical forests. A more recent hypothesis proposes that their stature is the outcome of a life history trade-off in high-mortality environments, where ea…

  • Influence of evolutionary forces and demographic processes on the genetic structure of three Croatian populations

    Open AccessJelena Šarac, Tena Šarić et al.ARTICLEAnnals of Human Biology2012

    The results can be explained by the effect evolutionary forces have on genetic structure, which is in line with the specific demographic histories of the islands. An additional research value of these two island isolates is the appearance of certain Mendelian disorders, highlighting their importance in epidemiological studies

  • An Aboriginal Australian Genome Reveals Separate Human Dispersals into Asia

    Open AccessMorten Rasmussen, Xiaosen Guo et al.ARTICLEScience2011

    Whole-genome data indicate that early modern humans expanded into Australia 62,000 to 75,000 years ago.

  • Genetic diversity and evidence for population admixture in Batak Negritos from Palawan

    Open AccessClarissa Scholes, Katherine Siddle et al.ARTICLEAmerican Journal of Physical…2011Citada por: 8Referências: 44

    Anthropologists have long been fascinated by the isolated hunter–gatherer populations in Southeast Asia (SEA) collectively known as “Negritos.” However, the origins and affinities of these groups remain unresolved. Negritos are characterized by their short stature, dark skin color, and wiry hair, and they inhabit the Philippines, Malay Peninsula, and the Andaman Islands. Among Philippine Negritos, the Batak are of particular interest in understan…

  • Ancient human genome sequence of an extinct Palaeo-Eskimo

    Open AccessMorten Rasmussen, Yingrui Li et al.ARTICLENature2010

    We report here the genome sequence of an ancient human. Obtained from ∼4,000-year-old permafrost-preserved hair, the genome represents a male individual from the first known culture to settle in Greenland. Sequenced to an average depth of 20×, we recover 79% of the diploid genome, an amount close to the practical limit of current sequencing technologies. We identify 353,151 high-confidence single-nucleotide polymorphisms (SNPs), of which 6.8% hav…

  • Ancient DNA from European Early Neolithic Farmers Reveals Their Near Eastern Affinities

    Open AccessWolfgang Haak, Oleg Balanovsky et al.ARTICLEPLOS Biology2010

    In Europe, the Neolithic transition (8,000-4,000 B.C.) from hunting and gathering to agricultural communities was one of the most important demographic events since the initial peopling of Europe by anatomically modern humans in the Upper Paleolithic (40,000 B.C.). However, the nature and speed of this transition is a matter of continuing scientific debate in archaeology, anthropology, and human population genetics. To date, inferences about the …

  • Beringian Standstill and Spread of Native American Founders

    Open AccessErika Tamm, Toomas Kivisild et al.ARTICLEPLoS ONE2007

    Native Americans derive from a small number of Asian founders who likely arrived to the Americas via Beringia. However, additional details about the initial colonization of the Americas remain unclear. To investigate the pioneering phase in the Americas we analyzed a total of 623 complete mtDNAs from the Americas and Asia, including 20 new complete mtDNAs from the Americas and seven from Asia. This sequence data was used to direct high-resolution…

  • An mtDNA perspective of French genetic variation

    Open AccessChrystelle Richard, Erwan Pennarun et al.ARTICLEAnnals of Human Biology2007

    The mtDNA haplogroup composition of the French does not differ significantly from the surrounding European genetic landscape. At a finer grain, microgeographical differentiation can be revealed, as shown for the French Basque country and for Brittany

  • Ancient DNA from the First European Farmers in 7500-Year-Old Neolithic Sites

    Open AccessWolfgang Haak, Peter Forster et al.ARTICLEScience2005

    The ancestry of modern Europeans is a subject of debate among geneticists, archaeologists, and anthropologists. A crucial question is the extent to which Europeans are descended from the first European farmers in the Neolithic Age 7500 years ago or from Paleolithic hunter-gatherers who were present in Europe since 40,000 years ago. Here we present an analysis of ancient DNA from early European farmers. We successfully extracted and sequenced inta…

  • The Emerging Limbs and Twigs of the East Asian mtDNA Tree

    Open AccessToomas Kivisild, Helle-Viivi Tolk et al.ARTICLEMolecular Biology and Evolution2002

    We determine the phylogenetic backbone of the East Asian mtDNA tree by using published complete mtDNA sequences and assessing both coding and control region variation in 69 Han individuals from southern China. This approach assists in the interpretation of published mtDNA data on East Asians based on either control region sequencing or restriction fragment length polymorphism (RFLP) typing. Our results confirm that the East Asian mtDNA pool is lo…

  • The Concepts of Richard Indreko About the Origin of the Finno-Ugric Speakers and the Population Genetics of the Extant North-East European Populations

    Open AccessKristiina Tambets, Siiri Rootsi et al.ARTICLETrames Journal of the Humanities…2001

    Archaeologists define their findings in terms of cultures and industries, linguists operate with languages, and the basic unit in biological anthropology is population. Intermarriages of these three systems have raised, and are still doing so, fascinatingly controversial speculations. In the current paper our intention is to discuss the accumulating data of population genetics in a specific context: in the light of scenarios of Richard Indreko, s…
