Darwin believed that small and useful variations make some species more adapted to the changing environment than others. Out of heterogenous population, nature selects the best adapted individuals while less fit or unfit are rejected because the unfit ones fail to survive and reproduce. This was called natural selection by Darwin and survival of the fittest by Wallace.
