  1. 1. 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

  3. 2. A History under Siege : Intensive Agriculture in the Mbulu Highlands, Tanzania, 19th Century to the Present

    Författare :Lowe Börjeson; Mats Widgren; Yusufu Lawi; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Landscape; Environmental history; Geography; Land use change; Population pressure; Incremental change; Landesque capital; Self-reinforcing processes; Detailed mapping; Participatory mapping; Oral history; Farming practices; Aerial photographs; Landscape photographs; Iraqw; Human geography; Kulturgeografi;

    Sammanfattning : This doctoral thesis examines the history of the Iraqw’ar Da/aw area in the Mbulu Highlands of northern Tanzania. Since the late nineteenth century this area has been known for its intensive cultivation, and referred to as an “island” within a matrix of less intensive land use. LÄS MER

  4. 3. Divergence, admixture and continuity in the human past : Demographic inference using ancient and modern genomes

    Författare :James McKenna; Mattias Jakobsson; Per Sjödin; Ida Moltke; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Human evolution; population genetics; ancient genomes; population continuity; divergence; Biology with Specialisation in Human Evolution and Genetics; Biologi med inriktning mot människans evolution och genetik;

    Sammanfattning : Demographic forces shaping the genetic variation we observe today can include population divergences, admixture events and continuity through time. The advancement of high-throughput sequencing technologies, together with developments in molecular and bio-informatics methods, mean the number of ancient genomes available for inference has risen steeply.

  5. 4. Mitochondria and Human Evolution

    Författare :Max Ingman; Ulf Gyllensten; Peter Underhill; Uppsala universitet; []
    Nyckelord :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

    Författare :Svante Karlsson; Sune Berger; Gerhard Gustafsson; Tor Selstad; Karlstads universitet; []
