许多作者认为，雌性选择的性选择可能会增加物种形成率，从而产生分类多样性。使用姐妹类群比较，我们发现雀形目鸟类类群内的性二色物种的比例之间存在显着的正相关关系，这些类群中的物种数量。如果雀形目鸟类的性二色性是通过雌性选择的行为进化而来的，那么理论就预测了这一结果。
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 correlation between the proportion of sexually dichromatic species within taxa of passerine birds, and the number of species in those taxa. Theory predicts this result if sexual dichromatism in passerines has evolved through the action of female choice.
