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 is the type of natural selection that the Grants observed in the beak size of Galpagos finches. Because these hybrid females receive their single Z chromosome from their cactus finch father there is no gene flow on Z chromosomes between species through these hybrid females. Some of these species have only been separated for a few hundred thousand years or less. Their beaks are specific to the type of diet they eat, which in turn is reflective of the food available.
