  • ‘Behavioral studies over the last decade have revealed an unexpected diversity of rather sophisticated social behavior, including even eusociality.’
  • ‘Many researchers expected that this would result in extreme inbreeding and high relatedness within colonies and would thus explain the evolution of eusociality in naked mole-rats.’
