    Evolutionary loss of foot muscle during development with characteristics of atrophy and no evidence of cell death

    Mai P Tran et al.
    Evolutionary loss of foot muscle in a bipedal rodent shares similarities with skeletal muscle atrophy, which is typically considered a pathological response to injury or disease.

    Multicellularity: How contraction has shaped evolution

    Mukund Thattai
    Two new unicellular organisms reveal that coordinated contractions of groups of cells using actomyosin predated animal multicellularity during evolution.

    The Natural History of Model Organisms: Insights into the evolution of social systems and species from baboon studies

    Julia Fischer et al.
    Wild baboons are an excellent model to study complex evolutionary processes such as speciation and hybridization, as well as the links between sociality, longevity and reproductive success.

    An ancestral apical brain region contributes to the central complex under the control of foxQ2 in the beetle Tribolium

    Bicheng He et al.
    An ancestral apical brain center contributed to the evolution of the insect central complex requiring foxQ2, which is essential for the development of midline structures of the insect brain.

    Adaptation to mutational inactivation of an essential gene converges to an accessible suboptimal fitness peak

    João V Rodrigues, Eugene I Shakhnovich
    When an essential metabolic gene in E. coli is mutationally inactivated, subsequent evolution rarely reverts the mutation to wild type but rather follows unexpected paths that rewire metabolic fluxes.

    Philosophy of Biology: The meanings of 'function' in biology and the problematic case of de novo gene emergence

    Diane Marie Keeling et al.
    A lexicon to help scientists and philosophers discuss the meaning of function in molecular biology more clearly is proposed.

    Evolutionary pathways to antibiotic resistance are dependent upon environmental structure and bacterial lifestyle

    Alfonso Santos-Lopez et al.
    Bacteria growing in biofilms evolve antimicrobial resistance via different pathways and generate greater genetic diversity than well-mixed populations, selecting fitter but less resistant genotypes.

    Bacterial Evolution: The road to resistance

    Devon M Fitzgerald
    The way that bacteria grow—either floating in liquid or attached to a surface—affects their ability to evolve antimicrobial resistance and our ability to treat infections.

    Comment on 'Single nucleus sequencing reveals evidence of inter-nucleus recombination in arbuscular mycorrhizal fungi'

    Benjamin Auxier, Anna Bazzicalupo
    We are writing to comment on the article by Chen et al. (2018) about inter-nucleus recombination in arbuscular mycorrhizal fungi.

    Extraocular, rod-like photoreceptors in a flatworm express xenopsin photopigment

    Kate A Rawlinson et al.
    A new opsin receptor is light-sensitive and expressed in a unique type of photoreceptor in a flatworm that encloses over 400 sensory cilia within its cell membrane.
