Cooperative breeding in South American hunter-gatherers.
Evolutionary researchers have recently suggested that pre-modern human societies habitually practised cooperative breeding and that this feature helps explain human prosocial tendencies. Despite circumstantial evidence that post-reproductive females and extra-pair males both provide resources required for successful reproduction by mated pairs, no study has yet provided details about the flow o...
متن کاملWhat drives cooperative breeding?
Cooperative breeding, in which more than a pair of conspecifics cooperate to raise young at a single nest or brood, is widespread among vertebrates but highly variable in its geographic distribution. Particularly vexing has been identifying the ecological correlates of this phenomenon, which has been suggested to be favored in populations inhabiting both relatively stable, productive environmen...

Cooperative breeding is characterized by a combination of group living and alloparental care, i.e., the care of others’ offspring. Typically, young of previous broods remain in their natal territory and help raising subsequent offspring of dominant breeders. Hence, the characteristic of cooperative breeding is the joint occurrence of delayed dispersal of young with a propensity to help caring f...
متن کاملCooperative behaviour in cooperative breeders: costs, benefits, and communal breeding.
In this issue, Bergmüller et al. (2007) have provided a valuable review paper, re-establishing cooperative breeding within a theoretical framework in field studies of cooperative breeding vertebrates. I am in agreement with the authors in their outlook and suggestions. In this critical review, I wish to (1) review the costs and benefits approach previously taken in the field, (2) evaluate commu...
متن کاملCooperation theory of cooperative breeding.
Cooperative breeding is the joint raising of offspring by wo or more individuals, where at least one of them is not he genetic parent of the young. The key characteristics of ooperative breeding systems are diversity of social behaviours ithin and between groups and high variation of factors influncing conflict over reproduction (for review see Komdeur, 006). In the second half of the 20th cent...
