    Dopamine drives Drosophila sechellia adaptation to its toxic host

    Sofía Lavista-Llanos et al.
    The insect dopaminergic system serves an important function in the regulation of ontogenesis and early development, contributing to the evolutionary processes that limit the ecological niche of Drosophila sechellia.

    Natural variation in sugar tolerance associates with changes in signaling and mitochondrial ribosome biogenesis

    Richard G Melvin et al.
    The optimal macronutrient composition, macronutrient space, varies strongly between closely related species and is determined by genetic changes in regulatory genes that globally reprogram gene expression profiles of metabolic pathways.

    Evolved differences in larval social behavior mediated by novel pheromones

    Joshua D Mast et al.
    A novel pheromone/receptor neuron pair mediates attraction between Drosophila larvae, and evolved differences in pheromone signaling underlie changes in social behavior between drosophilid species.

    Evolutionary expansion of apical extracellular matrix is required for the elongation of cells in a novel structure

    Sarah Jacquelyn Smith et al.
    A new morphological structure evolved through extreme changes in cell height requires novel connections to an extracellular matrix network, which predates the origin of structure.

    Cre-assisted fine-mapping of neural circuits using orthogonal split inteins

    Haojiang Luan et al.
    A genetic method allows neurons to be individually identified and characterized by combining information about both their developmental origins and their mature patterns of gene expression.

    Importance of miRNA stability and alternative primary miRNA isoforms in gene regulation during Drosophila development

    Li Zhou et al.
    Selective degradation of mature miRNAs shapes temporal miRNA expression patterns and is important for proper regulation of target genes to support normal development of Drosophila embryos.

    High-resolution mapping reveals hundreds of genetic incompatibilities in hybridizing fish species

    Molly Schumer et al.
    Genetic incompatibilities are common and widely distributed throughout the genomes of swordtail fish, and prevent the regions of the genome around them from being exchanged between different species.

    Synteny-based analyses indicate that sequence divergence is not the main source of orphan genes

    Nikolaos Vakirlis et al.
    Homology information implicit in regions of conserved synteny allows quantification of gene origination by complete sequence divergence, revealing a larger-than-expected role for other mechanisms of origin, including de novo origination.
