    The mlpt/Ubr3/Svb module comprises an ancient developmental switch for embryonic patterning

    Suparna Ray et al.
    mille-pattes micropeptides have conserved function in insect embryonic patterning together with transcription factor Shaven-baby and ubiquitin ligase Ubr3, except in flies wherein restoring broad embryonic Svb expression restores patterning potency.

    Long-term balancing selection drives evolution of immunity genes in Capsella

    Daniel Koenig et al.
    Retention of genetic diversity at immune-related loci drives the pattern of genetic variation in selfing Capsella.

    Quantitative uniqueness of human brain evolution revealed through phylogenetic comparative analysis

    Ian F Miller et al.
    The exceptionally large size of the human brain is the result of accelerating evolution towards larger brains in hominins, but is not the product of neocortical expansion.

    The presence and absence of periplasmic rings in bacterial flagellar motors correlates with stator type

    Mohammed Kaplan et al.
    A correlation between the periplasmic embellishment of the flagellar motor and its stator system type is described, motors with dual H+-dependent stator systems have one periplasmic ring formed by MotY.

    Quorums enable optimal pooling of independent judgements in biological systems

    James AR Marshall et al.
    Consideration of signal detection theory shows how decision ecology relates to optimal collective decisions, helping explain the prevalence of quorum-sensing in even the simplest collective systems, such as bacterial communities.

    Cryptic genetic variation shapes the adaptive evolutionary potential of enzymes

    Florian Baier et al.
    Genetic change among enzyme orthologous with similar phenotypic properties can cause substantial differences in evolutionary response to a new enzyme function in terms of their molecular and fitness outcomes.

    Emergence of trait variability through the lens of nitrogen assimilation in Prochlorococcus

    Paul M Berube et al.
    In the context of an organism's ecology, physiology, and macroevolutionary history, inheritance and gene loss can yield emergent patterns of trait variability that give the appearance of gene acquisition.

    Expansion of the fatty acyl reductase gene family shaped pheromone communication in Hymenoptera

    Michal Tupec et al.
    A fatty acyl reductase gene family expansion in the Hymenoptera crown group led to recruitment of novel pheromone-biosynthetic enzymes and is linked to evolution of pheromone marking behavior.

    Molecular basis of wax-based color change and UV reflection in dragonflies

    Ryo Futahashi et al.
    UV-reflective dragonfly wax is shown to consist of very long-chain methyl ketones and aldehydes, and a synthetic dragonfly wax spontaneously forms light-scattering fine structures with strong UV reflection.

    Evolutionary pathways of repeat protein topology in bacterial outer membrane proteins

    Meghan Whitney Franklin et al.
    There is a strand-based evolutionary mechanism for the diversification of outer membrane proteins, which has implications for how repeat proteins are created and for how outer membrane proteins fold.
