| hybrid speciation leads to novel male secondary sexual ornamentation of an amazonian bird. | hybrid speciation is rare in vertebrates, and reproductive isolation arising from hybridization is infrequently demonstrated. here, we present evidence supporting a hybrid-speciation event involving the genetic admixture of the snow-capped (lepidothrix nattereri) and opal-crowned (lepidothrix iris) manakins of the amazon basin, leading to the formation of the hybrid species, the golden-crowned manakin (lepidothrix vilasboasi). we used a genome-wide snp dataset together with analysis of admixture ... | 2018 | 29279398 |
