Eusociality
The most extreme form of social cooperation in nature—division of labor, reproductive altruism, overlapping generations—studied by Wilson in ants, bees, and termites as the arrangement that produced the most ecologically dominant organisms in history, and now a structural template for understanding multi-agent AI systems and the conditions under which cooperation among self-interested agents can be engineered.
Eusociality is the condition
E. O. Wilson studied throughout his career in the social insects: a society in which individuals divide labor, most members forgo their own reproduction to support the colony, and overlapping generations care cooperatively for the young. It is among the rarest and most powerful arrangements in all of biology, having evolved only a handful of times in the entire history of life, yet the lineages that achieved it—ants, bees, wasps, termites—came to dominate their environments utterly, accounting for a vast share of the animal biomass on land. Wilson's central insight was that eusociality is not merely a form of social organization but a biological superpower: the colony's collective intelligence, achieved through local rules and stigmergic coordination rather than central command, solves problems of resource allocation, defense, and adaptation that would tax any individual. The same insight applies to
