Such modifications enable such individuals to live longer than their peers, and breed over time to produce more offspring who also exhibit these traits.

Natural selection takes place and is determined by the fitness of an individual , it contributes to evolutionary change as individuals with certain traits reproduce, the traits become fixed and prevalent within the population.
