Various hypotheses have been proposed to account for the function of sexual swellings in female primates, but few empirical data exist to test predictions arising from these hypotheses. Controversy has recently arisen over a field study that appeared... Read More about Sexual swellings in mandrills (Mandrillus sphinx): a test of the reliable indicator hypothesis.
