  1. 1. Mitochondria and Human Evolution

    Författare :Max Ingman; Ulf Gyllensten; Peter Underhill; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Genetics; mitochondria; hominidae; human evolution; population genetics; Genetik; Clinical genetics; Klinisk genetik; Genetics; genetik;

    Sammanfattning : Mitochondrial DNA (mtDNA) has been a potent tool in studies of the evolution of modern humans, human migrations and the dynamics of human populations over time. The popularity of this cytoplasmic genome has largely been due to its clonal inheritance (in Man) allowing the tracing of a direct genetic line. LÄS MER

  2. 2. Modelling Evolution : From non-life, to life, to a variety of life

    Författare :Yu Liu; David J. T. Sumpter; Peter Dittrich; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; NATURAL SCIENCES; Mathematical biology; Biocomplexity; Artificial chemistry; Ecosystem evolution; Origin of life; Self-replication; Prebiotic evolution; Collectively-catalytic; Golden ratio; Tillämpad matematik och statistik; Applied Mathematics and Statistics;

    Sammanfattning : Life is able to replicate itself, e.g., a microorganism is able to divide into two identical ones, and a single plant is able to forest a whole island. LÄS MER

  3. 3. Where our feet have taken us : Examples of human contact, migration, and adaptation as revealed by ancient DNA

    Författare :Alexandra Coutinho; Mattias Jakobsson; Helena Malmström; Carina Schlebusch; Tom Gilbert; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Human demography; migration; adaptation; human contact; ancient DNA; human evolution; African prehistory; Scandinavian prehistory; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : In spite of our extensive knowledge of the human past, certain key questions remain to be answered about human prehistory. One involves the nature of cultural change in material culture through time from the perspective of how different ancient human groups interacted with one another. LÄS MER

  4. 4. Human demographic history : Insights on the human past based on genomes from Southern through Central Africa

    Författare :Gwenna Breton; Mattias Jakobsson; Carina Schlebusch; Per Sjödin; Paul Verdu; David Comas; Uppsala universitet; []
    Nyckelord :high-coverage genomes; Sub-Saharan Africa; demography; genetic admixture; population genetics; human evolutionary genetics; Khoe-San; rainforest hunter-gatherers; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : Evidence from paleontology, archaeology and population genetics support that modern humans originated in Africa. While the out-of-Africa event and subsequent colonization of all continents are well documented, human history in Africa at that time and before is less studied. LÄS MER

  5. 5. Evolution of human alpha-herpesviruses

    Författare :Peter Norberg; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :HSV-1; HSV-2; VZV; evolution; recombination; phylogenetic analysis;

    Sammanfattning : Herpesviridae is a large virus family with more than 100 members, which are highly disseminated among animals. Three sub-families have been classified; alpha-herpesviruses, beta-herpesviruses and gamma-herpesviruses. LÄS MER
