Solution

4). The concept of natural selection explains that how a species can have breeding populations adapted to local conditions. Based on the principle of natural selection the selection of genotypes occurs and that would result in offspring with better reproductive capabilities. Natural selection always results in better survival of an organism, so the genetic changes driven by the natural selection make the species to adapt to the local conditions so that they can survive. These species may exhibit high genetic variation may be because outbreeding, but gradually due to the inbreeding in these adapted species, the genetic variation will be minimised and they evolve as a separate species.
