  2. 1. Morphometric analysis of Cambrian fossils and its evolutionary significance

    Author : Illiam Jackson; Graham Budd; Jorijntje Henderiks; Richard Mann; Nigel Hughes; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Extended Evolutionary Synthesis; phenotypic plasticity; genetic assimilation; phenotypic accommodation; Agnostus pisiformis; Mackinnonia; elliptical fourier analysis; species concept;

    Abstract : The Extended Evolutionary Synthesis (EES) is currently emerging as a theoretical alternative to the Modern Synthesis (MS) in which to frame evolutionary observations and interpretations. These alternative frameworks differ fundamentally in their understanding of the relative roles of the genotype, phenotype, development and environment in evolutionary processes and patterns.

  4. 2. Evolutionary genomics in Corvids : – From single nucleotides to structural variants

    Author : Matthias H. Weissensteiner; Jochen B.W. Wolf; Manfred Grabherr; Kateryna M. Makova; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolutionary genetics; genomics; population genetics; selection; recombination; chromosomal features; colouration; insertion; deletion; inversion; crow; tandem repeat; transposable element; gene expression;

    Abstract : Heritable genetic variation is the raw material of evolution and can occur in many different forms, from altering single nucleotides to rearranging stretches of millions at once. DNA mutations that result in phenotypic differences are the basis upon which natural selection can act, leading to a shift of the frequency of those mutations. READ MORE

  5. 3. Evolutionary innovation : Early industrial uses of genetic engineering

    Author : Maureen McKelvey; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biotechnology industry; Economics of innovation; Evolutionary Economics; Genentech; human growth hormone; Kabi; technological innovation; INTERDISCIPLINARY RESEARCH AREAS; TVÄRVETENSKAPLIGA FORSKNINGSOMRÅDEN;

    Abstract : Based on an analysis of biological and economic theories of evol~tion, this dissertation first specifies evolutionary innovation and then uses it toanalyze early industrial uses of genetic engineering. Innovation refers totechnological innovation processes, i.e. series of innovative activitiesresulting in technical change. READ MORE

  6. 4. 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

  7. 5. Evolutionary Approaches to Sequence Alignment

    Author : Marcin Bogusz; Simon Whelan; Jeffrey Thorne; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; molecular evolution; multiple sequence alignment; pair hidden Markov models; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Molecular evolutionary biology allows us to look into the past by analyzing sequences of amino acids or nucleotides. These analyses can be very complex, often involving advanced statistical models of sequence evolution to construct phylogenetic trees, study the patterns of natural selection and perform a number of other evolutionary studies.
