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) 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.
