  • Little is known about the evolutionary origins of the genes involved in butterfly pheromone synthesis. Here, Liénard et al. show that the biosynthetic pathways involved in the production of male courtship scents of the butterfly, Bicyclus anynana, are shared with females of many moth species.

  • Forest ecotypes of deer mice have longer tails than prairie ecotypes. This study shows that this difference is adaptive and involves changes in six genomic regions, one of which is an allele-specific reduction in Hoxd13 expression that leads to tail elongation.

  • The European corn borer consists of two sex pheromone races, leading to strong reproductive isolation which could represent a first step in speciation. Female sex pheromone production and male behavioural response are under the control of different genes, but the identity of these genes is unknown. These authors show that allelic variation in a gene essential for pheromone biosynthesis accounts for the phenotypic variation in female pheromone production, leading to race-specific signals.

  • Parental care in mice evolves through multiple genetic changes; one candidate is vasopressin, the reduced expression of which promotes parental nest-building behaviour in monogamous mice.

  • Across species there are large changes in sperm morphology, yet how and why is unclear. Here, the authors show in Peromyscus mice, that the sperm midpiece length influences swimming speed and male fertility, and is regulated by cell-type specific expression of a ubiquitously expressed gene, Prkar1a.
