    Natural selection causes some genotypes (or phenotypes) to be more successful at leaving offspring than other ones. With each generation, the traits being selected for will become slightly more common in the population and the traits being selected against will become slightly less common. Over time, the population can experience extreme changes.

    natural selection means 'selection by nature'

    means that a certain organism will survive in a certain nature only

    like lions will live only in warm temperate area ,

    they will die if they live in another nature like cold areas
