    A host beetle pheromone regulates development and behavior in the nematode Pristionchus pacificus

    Jessica K Cinkornpumin et al.
    A lipid-binding protein mediates both attraction and hypersensitivity to a beetle sex pheromone in a specific type of nematode-insect relationship known as necromeny.

    Evolution of neuronal anatomy and circuitry in two highly divergent nematode species

    Ray L Hong et al.
    The substrate for evolutionary divergence does not lie in changes in neuronal cell number or targeting, but rather in sensory perception and synaptic partner choice within invariant, prepatterned neuronal processes.

    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.

    Rapid diversification associated with a macroevolutionary pulse of developmental plasticity

    Vladislav Susoy et al.
    Evolutionary novelty is promoted by a macroevolutionary pulse of developmental plasticity, but is enhanced by secondary fixation, which permits developmental character release and further morphological exploration.

    Extensive intraspecies cryptic variation in an ancient embryonic gene regulatory network

    Yamila N Torres Cleuren et al.
    Quantitative genetic analyses reveal remarkably broad genetic variation underlies the requirement for two critical regulatory inputs into a core embryonic gene regulatory network within one animal species.

    Nematophagous fungus Arthrobotrys oligospora mimics olfactory cues of sex and food to lure its nematode prey

    Yen-Ping Hsueh et al.
    Genetic and behavior analyses show that Caenorhabditis nematodes are lured to the predator Arthrobotrys oligospora by olfactory mimicry of food and sex cues.

    Modular metabolite assembly in Caenorhabditis elegans depends on carboxylesterases and formation of lysosome-related organelles

    Henry H Le et al.
    Caenorhabditis elegans homologs of carboxylesterases that localize to intestinal organelles orchestrate the assembly of modular signaling molecules from building blocks that integrate diverse metabolic pathways.

    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.
