  • Studying the odorant receptor subfamily Or67a in Drosophila melanogaster and closely related species, the authors show that independent selection on co-expressed receptors has contributed to species-specific peripheral coding of olfactory information.

  • Fruit flies gain valuable information about their environment by sensing chemicals. Here, Arguello et al. show strong signals of recent selection on the chemosensory system of the fruit fly Drosophila melanogaster, consistent with the adaptation of populations to their local chemical environment.

  • Chemosensory tissues are remarkably variable between species but the cause of this diversity is unclear. Here, the authors conduct transcriptomic analyses of chemosensory tissues from diverse Drosophila species, revealing evidence of stabilizing selection and recent species- and sex-specific changes.

  • A neurogenetic model, Drosophila sechellia—a relative of Drosophila melanogaster that has developed an extreme specialization for a single host plant—sheds light on the evolution of interspecific differences in behaviour.

  • Many obligate symbionts, including parasites, have reduced genomes. A comparison of leaf-cutter ant genomes reveals parallel gene losses, particularly in olfactory receptors, in socially parasitic species compared to their closely-related hosts, consistent with relaxed selection for cooperative colony life in the parasites.

  • An international consortium reports the genomic sequence for ten Drosophila species, and compares them to two other previously published Drosophila species. These data are invaluable for drawing evolutionary conclusions across an entire phylogeny of species at once.

  • Drosophila sechellia, a species closely related to the model species Drosophila melanogaster, bypasses a premature stop codon in neuronal cells to express a functional olfactory receptor protein from an assumed pseudogene template.
