Abstract
Many authors have suggested that sexual selection by female choice may increase the speciation rate and hence generate taxonomic diversity. Using sister taxa comparisons, we find a significant positive correlat ion between the proportion of sexually dichromatic species within taxa of passerine birds, and the number of species in those taxa. Theory p redicts this result if sexual dichromatism in passerines has evolved t hrough the action of female choice.
