Dedicated developmental programing for group-supporting behaviors in eusocial honeybees.

The evolutionary changes from solitary to eusocial living in vertebrates and invertebrates are associated with the diversification of social interactions and the development of queen and worker castes. Despite strong innate patterns, our understanding of the mechanisms manifesting these sophisticated behaviors is still rudimentary. Here, we show that () manifests group-supporting behaviors in the honeybee () worker caste.

The function and evolution of a genetic switch controlling sexually dimorphic eye differentiation in honeybees.

Animals develop sex-specific morphological structures that are diverse between organisms. However, understanding the developmental and evolutionary mechanisms governing these traits is still limited and largely restricted to DM domain genes, which are conserved, sex-specific developmental regulators identified in genetic models. Here, we report a sex-specific developmental regulator gene, glubschauge (glu) that selectively regulates sexually dimorphic eye differentiation in honeybees.
