    Moderate nucleotide diversity in the Atlantic herring is associated with a low mutation rate

    Chungang Feng, Mats Pettersson ... Leif Andersson
    The Atlantic herring has the lowest mutation rate yet estimated in a vertebrate species and this partially explains its moderate nucleotide diversity given the large population size.

    Parallel evolution of influenza across multiple spatiotemporal scales

    Katherine S Xue, Terry Stevens-Ayers ... Jesse D Bloom
    Influenza evolution within infected hosts recapitulates many evolutionary dynamics observed at the global scale.

    Heredity: The gene family that cheats Mendel

    J Dylan Shropshire, Antonis Rokas
    Some alleles of the wtf gene family can increase their chances of spreading by using poisons to kill other alleles, and antidotes to save themselves.

    Chimeric origins of ochrophytes and haptophytes revealed through an ancient plastid proteome

    Richard G Dorrell, Gillian Gile ... Chris Bowler
    An in silico reconstruction of a chloroplast that existed hundreds of millions of years ago casts new insights in the evolutionary processes, endosymbioses and chimerism events that shape the origin of plastids.

    Evolution of reduced co-activator dependence led to target expansion of a starvation response pathway

    Bin Z He, Xu Zhou, Erin K O’Shea
    The phosphate starvation response network in a commensal yeast evolved to expand its downstream targets via changes in the main transcription factor's dependence on its co-activator, potentially altering the physiological response.

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

    Donato Giovannelli, Stefan M Sievert ... Costantino Vetriani
    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.

    Environment determines evolutionary trajectory in a constrained phenotypic space

    David T Fraebel, Harry Mickalide ... Seppe Kuehn
    Experimental evolution shows that when selection acts on two traits constrained by a trade-off, the direction of phenotypic evolution depends on the environment.

    Rapid evolution of the human mutation spectrum

    Kelley Harris, Jonathan K Pritchard
    Heritable mutations tend to occur within different DNA sequence contexts in different human populations, suggesting that DNA replication and repair often change in efficacy over only a few hundred generations of evolution.

    Population Genetics: Global clues to the nature of genomic mutations in humans

    Aylwyn Scally
    An analysis of worldwide human genetic variation reveals the footprints of ancient changes in genomic mutation processes.

    Evolutionary changes in transcription factor coding sequence quantitatively alter sensory organ development and function

    Simon Weinberger, Matthew P Topping ... Ariane Ramaekers
    The coding sequences of a very highly conserved family of neurogenic transcription factors from different species have evolved to generate proteins that have different life times causing them to display quantitatively different neural induction potentials.
