Genomic tools are allowing us to dissect the roles of genes and genetic architecture in social
evolution, and eusocial insects are excellent models. Numerous hypotheses for molecular …

The evolution of eusociality is a perennial issue in evolutionary biology, and genomic
advances have fueled steadily growing interest in the genetic changes underlying social …

Sweat bees have repeatedly gained and lost eusociality, a transition from individual to group
reproduction. Here we generate chromosome-length genome assemblies for 17 species …

A key mechanistic hypothesis for the evolution of division of labour in social insects is that a
shared set of genes co-opted from a common solitary ancestral ground plan (a genetic …

Eusocial insects, mostly Hymenoptera, have evolved unique colonial lifestyles that rely on
the perception of social context mainly through pheromones, and chemoreceptors are …

Taxon-restricted genes make up a considerable proportion of genomes, yet their
contribution to phenotypic evolution is poorly understood. We combined gene expression …

Eusociality has convergently evolved multiple times, but the genomic basis of caste-based
division of labor and degree to which independent origins of eusociality have utilized …

Background Reproductive division of labor in eusocial insects is a striking example of a
shared genetic background giving rise to alternative phenotypes, namely queen and worker …

Pollinators, including honey bees, routinely encounter potentially harmful microorganisms
and phytochemicals during foraging. However, the mechanisms by which honey bees …

Studies of the genetic basis and evolution of complex social behavior emphasize either
conserved or novel genes. To begin to reconcile these perspectives, we studied how the …
