I believe that hybrid zones provide an opportunity to investigate the evolution of reproductive isolation.Hybrid zones are areas where hybrid offspring of two divergent taxa are prevalent and there is a line in the genetic composition of populations from one taxon to the other. A hybrid zone allows researchers to see what happens when closely related species come together. Reproductive barriers may be strengthened or weakened, depending on environmental and genetic factors.
