“…Thus, genetic differentiation is prevalent throughout the genome, which differs from a suite of recent studies that have found patterns of widespread genomic homogeneity with a small number of loci likely underlying phenotypic differentiation in other avian taxa (Mason & Taylor, 2015;Poelstra et al, 2014;. Indeed, the deep evolutionary split that we documented between S. torqueola and S. morelleti is in stark contrast to the shallow evolutionary history that characterizes the southern capuchino radiation in the same genus, in which rapid and recent phenotypic differentiation and speciation are driven by a few loci of large effect (Campagna et al, 2017).…”

“…These observations highlight an additional implication of the speciation sieve: ancestral polymorphism may persist through multiple speciation events, especially rapid radiations, before it is sieved. As a result, multiple species pairs will share sieved regions and may appear as if they had undergone repeated local adaptation (e.g., Campagna et al., ).…”
