    Point of View: Towards a mechanistic foundation of evolutionary theory

    Michael Doebeli et al.
    A description of evolution that is based on birth-death processes, and in which fitness is at most a derived quantity, is advocated.

    Eco-evolutionary dynamics of nested Darwinian populations and the emergence of community-level heredity

    Guilhem Doulcier et al.
    Artificial selection on communities drives the evolution of interactions and establishes community-level inheritance.

    Genetic diversity of CHC22 clathrin impacts its function in glucose metabolism

    Matteo Fumagalli et al.
    Natural selection shaped CHC22 clathrin genetic variation in humans with different diets and potentially influenced the human insulin response.

    Immune genes are hotspots of shared positive selection across birds and mammals

    Allison J Shultz, Timothy B Sackton
    Pathogens, particularly viruses, target the same genes over deep evolutionary time, resulting in shared signatures of positive selection and transcriptional responses at the same genes.

    Comprehensive mapping of adaptation of the avian influenza polymerase protein PB2 to humans

    YQ Shirleen Soh et al.
    Complete mapping of human-adaptive mutations to the avian influenza PB2 protein shows how selection at key molecular interfaces combines with evolutionary accessibility to shape viral host adaptation.

    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.

    Evolution of substrate specificity in a retained enzyme driven by gene loss

    Ana Lilia Juárez-Vázquez et al.
    An integrated biochemical and evolutionary analysis shows how enzyme specificity evolves after gene loss during genome decay, implicating relaxation of purifying selection as a driving force for functional divergence.

    Genomic epidemiology of artemisinin resistant malaria

    MalariaGEN Plasmodium falciparum Community Project
    Plasmodium falciparum kelch13 mutations that cause artemisinin resistant malaria in Southeast Asia show markedly different patterns of evolutionary selection in Africa.

    Philosophy of Biology: The analysis of living systems can generate both knowledge and illusions

    Antony M Jose
    By thinking about experimental techniques in terms of six broad approaches – perturbation, visualization, substitution, characterization, reconstitution, and simulation – researchers may be able to generate more reliable inferences.
