Scientists have sketched a new map of the "evolutionary labyrinth" species must traverse to reach eusociality, the rare but spectacularly successful social structure where individuals cooperate to raise offspring. Their modeling shows that natural selection alone can explain the evolution of eusocial behavior, without the need for kin selection theory.
