    Mice and primates use distinct strategies for visual segmentation

    Francisco J Luongo, Lu Liu ... Doris Y Tsao
    The behavioral ability of mice and treeshrews to detect visual figures is highly texture dependent, unlike that of primates including macaques and mouse lemurs, and neural responses to figures in mouse visual cortex are similarly texture dependent.

    The layered costs and benefits of translational redundancy

    Parth K Raval, Wing Yui Ngan ... Deepa Agashe
    Manipulation of the E. coli translation machinery sheds new light on evolutionary constraints and optimization strategies for bacterial translation and growth.

    Nitrogenase resurrection and the evolution of a singular enzymatic mechanism

    Amanda K Garcia, Derek F Harris ... Betül Kaçar
    Life is constrained in its sampling of protein sequence space to catalyze one of the most energetically challenging biochemical reactions.

    Community diversity is associated with intra-species genetic diversity and gene loss in the human gut microbiome

    Naïma Madi, Daisy Chen ... Nandita R Garud
    Longstanding eco-evolutionary theories are tested using shotgun metagenomic data from the human gut microbiome, showing links between community diversity and the evolutionary trajectory of a focal species within the community.

    Polygenic adaptation from standing genetic variation allows rapid ecotype formation

    Nico Fuhrmann, Celine Prakash, Tobias S Kaiser
    Baltic and Arctic ecotypes of the marine midge Clunio emerged from a recent adaptive radiation, which is based on standing genetic variation at many loci involved in time-keeping and nervous system development.

    The landscape of antibody binding affinity in SARS-CoV-2 Omicron BA.1 evolution

    Alief Moulana, Thomas Dupic ... Michael M Desai
    The study of the interactions between 65,356 variants of the SARS-CoV-2 receptor binding domain and a panel of monoclonal antibodies shows that Omicron’s escape is driven by a small number of large effect mutations.

    Peripheral and central employment of acid-sensing ion channels during early bilaterian evolution

    Josep Martí-Solans, Aina Børve ... Timothy Lynagh
    Expression patterns and biophysical properties of acid-sensing ion channels in numerous bilaterian animals offer insight into the deployment of ion channels by the evolving nervous system in complex animals.

    Balancing selection on genomic deletion polymorphisms in humans

    Alber Aqil, Leo Speidel ... Omer Gokcumen
    The effect of balancing selection on the human genome is greater than previously appreciated, especially affecting large deletion variations.

    Sweepstakes reproductive success via pervasive and recurrent selective sweeps

    Einar Árnason, Jere Koskela ... Bjarki Eldon
    Selective sweepstakes from pervasive positive selection, rather than demographic changes or random sweepstakes reproduction, is the primary determinant of reproductive skew and genetic diversity in the highly prolific Atlantic cod.

    Relating pathogenic loss-of-function mutations in humans to their evolutionary fitness costs

    Ipsita Agarwal, Zachary L Fuller ... Molly Przeworski
    Loss-of-function mutations in human genes are an important class of disease causing variation, and estimates of their effects on evolutionary fitness can be used to evaluate their pathogenicity.
