One scenario is that the two species will merge into a single species combining gene variants from the two species, but perhaps a more likely scenario is that they will continue to behave as two species and either continue to exchange genes occasionally or develop reproductive isolation if the hybrids at some point show reduced fitness compared with purebred progeny. This shifts the distribution toward that extreme. Renowned evolutionary biologists Peter and Rosemary Grant have produced landmark studies of the Galpagos finches first made famous by Charles Darwin.
