2. 1. Ancient genomics of Baltic seals : Insights on the past Baltic grey seal and harp seal populations

   Author : Maiken Hemme Bro-Jørgensen; Kerstin Lidén; Morten Tange Olsen; Aikaterini Glykou; Olle Karlsson; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Ancient DNA; Baltic Sea; DNA preservation; extinction; mitogenome; seal hunting; sex identification; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

   Abstract : This thesis aims to study and describe the ancient populations of grey and harp seals in the Baltic Sea, and to present new methodological approaches for general use in ancient DNA studies.The dissertation is comprised of five studies: a review of the use of paleogenetics in studying ancient human-marine mammal interactions; a method paper investigating patterns of DNA preservation in ancient pinniped samples; a method paper presenting a genetic sex identification method for ancient pinnipeds; a population genomic study of the Baltic grey seal; and a population genomic study of the now extinct Baltic harp seal.

4. 2. From Fossil To Fact : The Denisova Discovery as Science in Action

   Author : Mattis Karlsson; Eva Hemmungs Wirtén; Martin Fredriksson; Andreas Nyblom; Staffan Bergwik; Linköpings universitet; []
   Keywords : HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; Actor network theory; aDNA; ANT; Denisovan; Denisova human; Denisova hominin; DNA; Knowledge; Bruno Latour; Science; Science in action; STS; Wikipedia;

   Abstract : From Fossil to Fact: The Denisova Discovery as Science in Action is a study of the (actor) networked relations that make and shape science through the case of the discovery of the Denisova human.In 2010, Nature published the article “The complete mitochondrial DNA genome of an unknown hominin from southern Siberia”, the article revealed the results of mtDNA sequencing of a fossilised finger bone excavated from the Denisova Cave in Siberia, showing that the fossil belonged to an individual of a previously unknown type of humans, the Denisovans.

5. 3. Archaeological Genetics - Approaching Human History through DNA Analysis

   Author : Evangelia Daskalaki; Anders Götherström; Mattias Jakobsson; Walther Parson; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ancient DNA; pyrosequencing; molecular genetics; aDNA; neolithization; evolutionary genetics; mtDNA; viking age; archaeological genetics; genetik; evolutionsgenetik; naturvetenskap; neolitisering; vikingatid; arkeologisk genetik; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

   Abstract : There are a variety of archaeological questions, which are difficult to assess by traditional archaeological methods. Similarly, there are genetic and population genetic questions about human evolution and migration that are difficult to assess by studying modern day genetic variation. READ MORE

6. 4. Methodology and Infrastructure for Statistical Computing in Genomics : Applications for Ancient DNA

   Author : Kristiina Ausmees; Carl Nettelblad; Mattias Jakobsson; Flora Jay; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; statistical computing; genotype imputation; ancient DNA; deep learning; dimensionality reduction; genetic clustering; distributed computing; Scientific Computing; Beräkningsvetenskap;

   Abstract : This thesis concerns the development and evaluation of computational methods for analysis of genetic data. A particular focus is on ancient DNA recovered from archaeological finds, the analysis of which has contributed to novel insights into human evolutionary and demographic history, while also introducing new challenges and the demand for specialized methods.

7. 5. Migration in Prehistory : DNA and stable isotope analyses of Swedish skeletal material

   Author : Anna Linderholm; Kerstin Lidén; Oliver Craig; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Migration; ancient DNA; stable isotopes; δ13C; δ15N; δ34S; mtDNA; lactose tolerance; Neolithic; Pitted Ware culture; Funnel Beaker culture; Vikings; Öland; Rössberga; Birka; Björned; Archaeology; Arkeologi; Archaeological Science; laborativ arkeologi;

   Abstract : The main aim of this thesis is to show how scientific methods may be used to look at migration in prehistory on the basis of archaeological material. The individuals examined represent the period 4 000 BC to 1 000 AD and have their geographical origins in various parts of Sweden.Ancient DNA analysis is employed in three cases. READ MORE
