Evolution occurs when nature selects mutation that increase reproduction.
Explanation:
'Survival of the fittest', this is the major principle followed in the process of Natural selection.
This explains that nature will select only those individual who are fitter than rest of the population.
A more fit individual will show a greater reproductive success.
A greater reproductive success can be attained by a mutation that increases reproduction.
Thus population of such individual prove itself to be more fit to maintain its population and gene pool.
Soon the population with lower reproductive success will be eliminated and the evolved population with greater reproductive success will stabilize as a result of Natural selection.
Thus, Evolution takes place when Nature selects Mutation that increase reproduction.
