Abstract Increased coordination challenges, such as in the negotiation of group movement and activity, has been suggested to promote communicative complexity. This hypothesis, however, has rarely been tested within and between species, specifically in relation to signal combinations. We compared two primates, chimpanzees and mangabeys, living in the same dense forest habitat, but with varying degrees of fission–fusion dynamics. In both species, we examined whether spatial coordination challenges
