Abstract: | Females in some species of Old World monkeys and apes vocalizeafter copulation, but the function of these vocalizations isnot clear. In this article, we examine the hypothesis that copulationcalls are a form of postcopulatory female choice. Accordingto this hypothesis, copulation calls are honest signals of fertility(i.e., ovulation) that are used by females to encourage mateguarding by their preferred mating partners and reduce the likelihoodof sperm competition. Evidence in favor of this hypothesis isreviewed and discussed in relation to other hypotheses. We suggestthat the evolution of female copulation calls in primates islinked to the evolution of other female mating signals suchas exaggerated sexual swellings, the potential for sperm competition,and the opportunity for precopulatory female mate choice. |
