Convergent eusocial evolution is based on a shared reproductive groundplan plus lineage-specific plastic genes

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 common genes remain largely unknown. Here we characterize caste-specific transcriptomic profiles across development and adult body segments from pharaoh ants ( Monomorium pharaonis ) and honey bees ( Apis mellifera ), representing two independent origins of eusociality....
