Significance
          
            In some cases similar molecular programs (i.e., conserved genes and gene networks) underlie the expression of phenotypic traits that evolve repeatedly across diverse species. We investigated this possibility in the context of social behavioral response, using a comparative genomics approach for three distantly related species: house mouse (
            Mus musculus
            ), stickleback fish (
            Gasterosteus aculeatus
            ), and honey bee (
            Apis mellifera
            ). An experience of territory intrusion modulated similar brain functional processes across species, including hormone-mediated signal transduction, neurodevelopment, chromosome organization, and energy metabolism. Several homologous transcription factors also responded consistently to territory intrusion, suggesting that shared neuronal effects may involve transcriptional cascades of evolutionarily conserved genes. These results indicate that conserved genetic “toolkits” are involved in independent evolutions of social behavior.
