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 an example of character displacement. [10] The following two years suggested that natural selection could happen very rapidly. professor melissa murray.

Experimental confirmation of natural selection is interpreted as proof of darwin's theory. Peter and Rosemary Grant chose to study the Finches in the Galapagos because they were hybrid. These second-generation cheetahs reproduce and their offspring (third-generation) who inherit this trait for speed are more successful at hunting prey.
