    Bacterial contribution to genesis of the novel germ line determinant oskar

    Leo Blondel et al.
    Evidence suggests that the oskar gene, a critical germ line determinant in insects, was formed by fusion of bacterial and eukaryotic sequences at least 450 million years ago.

    Rarity is a more reliable indicator of land-use impacts on soil invertebrate communities than other diversity metrics

    Andrew Dopheide et al.
    Rarity metrics reveal pervasive negative impacts of agricultural land use on soil invertebrate communities, whereas widely-used richness and diversity metrics underestimate the magnitude of these impacts.

    Convergent evolution of small molecule pheromones in Pristionchus nematodes

    Chuanfu Dong et al.
    Unexpected structural diversity of nematode small molecules, as revealed by high-resolution phylogenetic analysis, suggests recurrent biochemical innovation, a pattern that is probably typical across animals.

    Disparate expression specificities coded by a shared Hox-C enhancer

    Steve W Miller, James W Posakony
    Tucked within a well-known story of diverging gene function is a single enhancer encoding two inseparable specificities that regulates two adjacent genes, each with different spatiotemporal expression patterns.

    Mushroom body evolution demonstrates homology and divergence across Pancrustacea

    Nicholas James Strausfeld et al.
    Demonstrating extreme diversity across crustaceans while contrasting with evolutionary stability in insects, mushroom body homologues further underpin the unity of Pancrustacea and shed new light on arthropod brain evolution.

    Robust olfactory responses in the absence of odorant binding proteins

    Shuke Xiao et al.
    Although odorant binding proteins are widely believed to be required for transport of odorants to receptors, six types of sensilla of Drosophila respond robustly in their absence to many odor stimuli.

    Evolutionary emergence of Hairless as a novel component of the Notch signaling pathway

    Steven W Miller et al.
    Hairless emerged as an evolutionarily novel regulatory protein that replaced an ancestral paradigm of direct co-repressor recruitment by Suppressor of Hairless, its partner transcription factor in the Notch signaling pathway.

    Seminal fluid compromises visual perception in honeybee queens reducing their survival during additional mating flights

    Joanito Liberti et al.
    After insemination, honeybee queens experience a rapid reduction in vision and flight performance, consistent with an ongoing sexual conflict over the number of mating flights that queens embark on.

    Adaptive substitutions underlying cardiac glycoside insensitivity in insects exhibit epistasis in vivo

    Andrew M Taverner et al.
    Genome engineering and phenotyping in vivo reveal surprising new features of adaptive amino acid substitutions that were previously inaccessible.

    Hemimetabolous insects elucidate the origin of sexual development via alternative splicing

    Judith Wexler et al.
    Sexual differentiation controlled by sex-specific mRNA splicing evolved in a step-wise manner in insects.
