New Study Reveals Cooperative Breeding Secrets In species like meerkats in the Kalahari Desert and cotton-top tamarins in South American rainforests, female group members often assist in raising offspring that aren’t their own—sometimes even forgoing reproduction themselves.
Sarah Benson-Amram at the University of Wyoming highlights that this cooperative breeding behavior is driven by kin selection and social cohesion, particularly when related females live together. In meerkat colonies, up to 70% of pups are cared for by non-mothers, while in marmoset groups, helpers can account for nearly half of all infant care duties. These findings underscore how evolutionary pressures shape complex social systems where survival depends on collective effort.
