Furor Erupts Over the Role of Self-Sacrifice in Evolution

Work addresses limitations of kin selection, a dominant theory since the 1960sScientists at Harvard University 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.Mathematical biologists Martin A. Nowak and Corina E. Tarnita and evolutionary biologist Edward O. Wilson present their work this week in the journal Nature. Their modeling shows that the straightforward natural selection theory alone can explain the evolution of eusocial behavior, without the need for kin selection theory."The empirical evidence gathered in our paper demonstrates that eusociality is exceedingly rare because species must navigate a lengthy evolutionary labyrinth to reach this state," says Wilson, the Pellegrino University Professor, Emeritus, at Harvard. "We hope our new theory for the evolution of eusociality will open up sociobiology to new avenues of researc
