Darwin recognized eusocial insect colonies—with sterile workers and fertile queens — as a challengetoevolutionary theory: it is tricky to explain why someindividualssacrifice their own reproductive potential in order toraise theoffspring of others. Kin selection theory, in whichindividualfitness derives from increasing the survival of arelatives’offspring, is often suggested as the explanation. In anAnalysisfeature, Martin Nowak, Corina Tarnita and Edward O. Wilsonpointout that this approach is not generally applicable. Instead,theysay, standard natural selection combined with precisemodels of population structure provides a simpler answer.
