So the individuals that survive and reproduce will have a different set of alleles that they pass on to their offspring. If two closely related species continue to produce hybrids, they will develop reproductive barriers to prevent production of hybrids, to ensure that they remain separate species. Given enough time, Darwin and Wallace argued, natural selection might produce new types of body parts, from wings to eyes. Two species that have recently diverged from each other can reproduce with each other, creating hybrid individuals that belong to the species of the parents' common ancestor. 10.3 theory of natural selection answer key.com.
