Introgression, the incorporation of genetic material from one (sub) species into the gene pool
of another by means of hybridization and backcrossing, is a common phenomenon in birds …

Hybridization is increasingly recognized as a creative evolutionary force contributing to
adaptation and speciation. Homoploid hybrid speciation—the process in which hybridization …

Adaptive radiations are prominent components of the world's biodiversity. They comprise
many species derived from one or a small number of ancestral species in a geologically …

Hybrid speciation is rare in vertebrates, and reproductive isolation arising from hybridization
is infrequently demonstrated. Here, we present evidence supporting a hybrid-speciation …

Speciation is a continuous and dynamic process, and studying organisms during the early
stages of this process can aid in identifying speciation mechanisms. The mallard (Anas …

Resolving evolutionary relationships and establishing population structure depends on
molecular diagnosability that is often limited for closely related taxa. Here, we use 3,200 …

Evolutionary history is typically portrayed as a branching phylogenetic tree, yet not all
evolution proceeds in a purely bifurcating manner. Introgressive hybridization is one process …

Background The impacts of hybridization on the process of speciation are manifold, leading
to distinct patterns across the genome. Genetic differentiation accumulates in certain …

In their recent article Nieto Feliner and colleagues discuss in detail our previous article “How
common is homoploid hybrid speciation?” They conclude that our criteria for homoploid …

Examining what happens when two closely related species come into secondary contact
provides insight into the later stages of the speciation process. The Zosteropidae family of …
