Darwin’s theory of evolution/ the base on natural selection or the theory of natural selection (Darwinism)

The first satisfactory explanation to the mechanism by which evolution takes place was proposed by Charles Darwin (1809-1882) and that was the theory of natural selection.

Natural selection is where by the well adapted organisms to changes in the environment are naturally favoured or selected for and survive while the poorly adapted organisms to changes in the environment are naturally selected against and die before reaching sexual maturity or before reproducing.

The well adapted and naturally favoured organisms which survive the changes in the environment pass on their beneficial traits/genes which made them to survive to their off springs (survival for the fittest)

And those which are less adapted will be naturally selected against and they will die off before reaching sexual maturity there fore leading to the elimination of un beneficial genes/traits from the population.
