Cooperative breeding systems, in which non breeding individuals provide care for the offspring of dominant group members, occur in less than 1% of mammals and are associated with social monogamy and the production of multiple offspring per birth (polytocy). Cooperative breeding and monogamy in mammalian societies ... While the association between cooperative breeding and relatively high relatedness between group members suggest that kin selection plays an important role in the evolution and maintenance of cooperative breeding, this should not be taken to suggest that direct fitness benefits do not also play an important part in maintaining cooperative and ...
