Hybrid speciation

Form of speciation involving hybridization between two different species
Two species mate resulting in a fit hybrid that is unable to mate with members of its parent species.

Hybrid speciation occurs when two divergent lineages (e.g., species) with independent evolutionary histories come into contact and interbreed. Hybridization can result in speciation when hybrid populations become isolated from the parental lineages, leading to divergence from the parent populations.
