    Polygenic adaptation on height is overestimated due to uncorrected stratification in genome-wide association studies

    Mashaal Sohail et al.
    Polygenic selection signals in humans estimated from previously existing GWAS should be viewed with caution due to concerns about residual population stratification.

    An integrative genomic analysis of the Longshanks selection experiment for longer limbs in mice

    João PL Castro et al.
    Genome sequencing of mice selected for longer limbs reveals that rapid selection response is due to both discrete loci and polygenic adaptation.

    Ecological adaptation in Atlantic herring is associated with large shifts in allele frequencies at hundreds of loci

    Fan Han et al.
    Hundreds of loci underlying ecological adaptation to different environmental conditions show striking differences in allele frequencies between ecotypes of Atlantic herring.

    Intra-species differences in population size shape life history and genome evolution

    David Willemsen et al.
    Population genetics in turquoise killifish wild populations reveals how small population size and genetic drift determine the accumulation of deleterious gene variants leading to short lifespan.

    Insight into the evolution of microbial metabolism from the deep-branching bacterium, Thermovibrio ammonificans

    Donato Giovannelli et al.
    The genome of Thermovibrio ammonificans encodes ancestral pathways (e.g., hydrogen oxidation) and more recently acquired ones (e.g., nitrate reduction) and a hybrid pathway for CO2 fixation.

    The Natural History of Model Organisms: Genetic, evolutionary and plant breeding insights from the domestication of maize

    Sarah Hake, Jeffrey Ross-Ibarra
    Comparing maize to its wild ancestor teosinte advances our understanding of how it and other cereal crops evolved, and also identifies the genetic variation that can contribute to important agricultural traits.
