Sexual selection predicts the rate and direction of colour divergence in a large avian radiation

What factors explain variation in the pace and trajectory of evolutionary divergence between lineages? Here, the authors show that a proxy measure for sexual selection intensity predicts both the rate and direction of plumage colour evolution in a diverse radiation of New World passerine birds.
