Hybrid speciation

Two species mate resulting in a fit hybrid that is unable to mate with members of its parent species.

Hybrid speciation is a form of speciation where hybridization between two different species leads to a new species, reproductively isolated from the parent species. Previously, reproductive isolation between two species and their parents was thought to be particularly difficult to achieve, and thus hybrid species were thought to be very rare. With DNA analysis becoming more accessible in the 1990s, hybrid speciation has been shown to be a somewhat common phenomenon, particularly in plants.[1][2] In botanical nomenclature, a hybrid species is also called a nothospecies.[3] Hybrid species are by their nature polyphyletic.[4]
