     Cooperative breeding species of nonhuman primates rely on all group members to exhibit infant care behaviors. This provides for an increase in survival of offspring and an opportunity for juveniles and subadults to learn parenting skills. Cooperative breeding species can live in family units or larger groups where there may be unrelated individuals carrying infants. The most notable cooperative breeders are members of the family Callitrichidae, marmosets and tamarins. All species of this family, except Callimico goeldii, produce multiple infants with each birth. Research on other nonhuman primates, particularly other New World monkeys and the prosimians are broadening our understanding of cooperative breeding as we comprehend that there are many more species of cooperative breeders than previously realized. Toni Ziegler and Stacey Tecot will give an overview of the nonhuman primates that have been reported to have cooperative breeding systems while Jeff French will set the stage with his evolutionary and ecological approach to cooperative breeding. Stacey Tecot and Manifred Eberle will provide data for two prosimian species of cooperative breeders while Karen Bales, Charles Snowdon, Anita Ginther and Toni Ziegler will discuss the proximate mechanisms involved in cooperative breeding in New World primates. Our goals are to learn about the taxa that display this behavior and the breadth of behaviors and physiology that should be considered cooperative breeding, determine what we know, and how best to conduct future comparative research.
