    The origin of the odorant receptor gene family in insects

    Philipp Brand et al.
    The insect odorant receptor gene family evolved at the base of the class Insecta before the evolution of flight and perhaps as an adaptation to terrestriality, and was therefore an important evolutionary novelty for insects.

    Mycobacterium ulcerans dynamics in aquatic ecosystems are driven by a complex interplay of abiotic and biotic factors

    Andrés Garchitorena et al.
    Different transmission routes of Mycobacterium ulcerans to aquatic organisms may prevail depending on local physico-chemical conditions.

    An insect-like mushroom body in a crustacean brain

    Gabriella Hannah Wolff et al.
    An insect-like mushroom body in one group of crustaceans, the mantis shrimps (Stomatopoda), suggests either an ancient origin of this center and its reduction and loss in other crustaceans, or an extraordinary example of convergent evolution with the insect mushroom body.

    Folded gastrulation and T48 drive the evolution of coordinated mesoderm internalization in flies

    Silvia Urbansky et al.
    Functional recapitulation of a likely evolutionary gain in gene expression shows that two genes are sufficient to switch mesoderm cell internalization from stochastic cell ingression to coordinated epithelial invagination.

    A gene horizontally transferred from bacteria protects arthropods from host plant cyanide poisoning

    Nicky Wybouw et al.
    The enzyme that allows some mites and insects to detoxify the hydrogen cyanide produced by plants has been identified.

    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.

    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.

    Evolution of insect olfactory receptors

    Christine Missbach et al.
    Insect specific olfactory receptors are not an adaptation to a terrestrial insect lifestyle, but evolved later in insect evolution.

    Shore crabs reveal novel evolutionary attributes of the mushroom body

    Nicholas Strausfeld, Marcel E Sayre
    Dramatic phenotypic divergence of crustacean mushroom bodies map to phylogenetic lineages, thereby offering unexplored opportunities for relating divergent cognitive centers to different ecologies and behavioral repertoires required to negotiate them.

    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.
