    'Palaeoshellomics’ reveals the use of freshwater mother-of-pearl in prehistory

    Jorune Sakalauskaite, Søren H Andersen ... Beatrice Demarchi
    Ancient proteomes from tiny shell ornaments were successfully characterised for the first time, showing the unexpected use of mother-of-pearl from local riverine molluscs in both coastal and inland prehistoric sites.

    A generally conserved response to hypoxia in iPSC-derived cardiomyocytes from humans and chimpanzees

    Michelle C Ward, Yoav Gilad
    Evolutionarily conserved hypoxic stress response genes are depleted for association with expression quantitative trait loci.

    Stem Cells: Getting to the heart of cardiovascular evolution in humans

    Alex Pollen, Bryan J Pavlovic
    Differences in the response of cardiomyocytes to oxygen deprivation in humans and chimpanzees may explain why humans are more prone to certain heart diseases.

    Evolution: Of starch and spit

    Mareike C Janiak
    Animals living alongside humans have multiple copies of the gene for alpha-amylase, the enzyme that breaks down starchy foods, and high levels of this protein in their saliva.

    Independent amylase gene copy number bursts correlate with dietary preferences in mammals

    Petar Pajic, Pavlos Pavlidis ... Omer Gokcumen
    Comprehensive analyses of amylase duplications and salivary activity across mammals underscore the importance of recurrent copy number variation as a flexible and rapid evolutionary mechanism.

    A non-archaeopterygid avialan theropod from the Late Jurassic of southern Germany

    Oliver WM Rauhut, Helmut Tischlinger, Christian Foth
    A new taxon from the Late Jurassic of southern Germany represents the second volant bird known from that time period and documents the improvement of flapping flight in bird evolution.

    Environmental heterogeneity can tip the population genetics of range expansions

    Matti Gralka, Oskar Hallatschek
    Environmental heterogeneity can dramatically reduce the efficacy of selection and alter the neutral evolutionary dynamics in microbial range expansions.

    Signal categorization by foraging animals depends on ecological diversity

    David William Kikuchi, Anna Dornhaus ... Thomas N Sherratt
    In richer, more even communities, foragers form broad categories among their food resources that can select for convergence among signals, including mimetic resemblances.

    Host-pathogen coevolution increases genetic variation in susceptibility to infection

    Elizabeth ML Duxbury, Jonathan P Day ... Ben Longdon
    A history of coevolution increases genetic variation in the susceptibility of Drosophila to viruses, largely by introducing major-effect resistance polymorphisms into populations.

    The African ape-like foot of Ardipithecus ramidus and its implications for the origin of bipedalism

    Thomas Cody Prang
    The most recent common ancestor of humans, chimpanzees, and bonobos possessed a foot adapted to terrestrial quadrupedalism and climbing.
