How does natural selection change population

Weball of the following are required for natural selection to create evolutionary change in a population except: A. variation in size or health of genetically identical individuals that is caused by environmental factors. B. genetic variation exists in a population WebNatural selection is a driving force in evolution and can generate populations that are better adapted to survive and successfully reproduce in their environments. However, natural selection cannot produce the perfect organism. Natural selection can only select on existing variation in the population. It does not create anything from scratch.
