Definition of eusociality in US English:



  • See eusocial

    • ‘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.’
    • ‘Cooperative breeding and eusociality are taxonomically widespread, occurring in social arthropods, colonial invertebrates, mammals, birds, fish, and bacteria.’
    • ‘Relatedness concepts have dominated the discussion on the evolution and maintenance of eusociality in social insects.’
    • ‘Darwin correctly anticipated that the key to the paradox of eusociality is the close genetic relatedness between an insect colony's breeders and its sterile workers.’
