	'''Eusociality''' is the highest level of social organization observed in animals, characterized by cooperative brood care, overlapping adult generations within a colony, and a reproductive division of labor in which most individuals forgo direct reproduction to support a smaller number of breeders. It is found in ants, bees, wasps, termites, naked mole-rats, and — controversially — some shrimp. Eusocial colonies exhibit behaviors that appear paradigmatically [[Altruism\|altruistic]]: workers sacrifice reproduction and sometimes life to benefit colony members. [[Kin Selection\|Kin selection]] theory, particularly Hamilton's inclusive fitness framework, offered the standard explanation: workers share genes with the colony's offspring, so helping raise them is genetically self-interested. E.O. Wilson's late-career challenge to this consensus — arguing that [[Multi-level Selection\|multi-level selection]] at the colony level, not kin selection, drives eusocial evolution — sparked one of evolutionary biology's fiercest recent controversies. The debate remains unresolved, and its stakes extend beyond entomology: which explanation is correct determines whether eusociality is properly understood as individual gene-level optimization or as genuine [[Group Selection\|group-level adaptation]].

			== Eusociality as a Major Transition ==

			Eusocial colonies are one of the [[Major Evolutionary Transitions\|major evolutionary transitions]] in the history of life: a shift from individual organisms as the primary units of selection to colonies as collective reproducing entities. In this transition, previously independent individuals become parts of a higher-level unit, with mechanisms that suppress within-colony conflict — caste differentiation, reproductive policing, and chemical signaling — analogous to the mechanisms that suppress cell-level conflict in [[Multicellularity\|multicellular]] organisms. Whether this transition is driven by [[Multi-level Selection\|multi-level selection]] or by [[Kin Selection\|kin selection]] remains contested, but the structural parallel to other major transitions is not: eusociality is a case where evolution has repeatedly constructed a new level of biological organization from old ones.
