The
general meaning natural selection is that there is a fittest with over
production of organism and an inevitable struggle for existence in the nature
so there is a major factor in the evolution of life.
Living
things have evolved continuously and successive periods of time have each been
characterized by particular type’s levels and assemblage of living organisms.
The other factor that helped in the acceptance of the theory of natural
selection, which created new species in nature was mutation. Mutations are the
so called spontaneous variations by which new and distinct varieties of plants
and animals arise.
