Baboons Ditch Their Close-Knit Male Friends When They Sire Offspring
Close friendships among males are rare in the animal kingdom, as males usually compete for rank and access to females. However, male friendships can also be beneficial for male reproduction, as friends can provide support in climbing the rank ladder or defending females from other males.
Scientists from the German Primate Center (DPZ) - Leibniz Institute for Primate Research - investigated the benefits of male friendships in wild Guinea baboons in Senegal. Guinea baboons are known for strong bonds among males and a lack of a clear male rank hierarchy. The researchers investigated whether males with many friends were more attractive to females because they may provide females and their offspring with better protection against predators.
Having many friends, however, was not related to male reproductive success. Instead, once males associated with females and began to sire offspring, they spent less time with other males. Although males in their prime maintained some social contact with other males, they drastically adjusted their investment of social time according to their life history stage to maximize reproductive success (Proceedings of the Royal Society B).
Male friends may provide emotional support; they can help in the defense of females against rivals or the acquisition of high social status. But everything changes once females enter the game. That much is true in Leonhard Bernsteinβs βWest Side Storyβ as in wild Guinea baboons.
