Question

Quizplus · Accepted Answer

Natural selection acts on existing genetic variation by selecting for traits that provide a survival and reproductive advantage in a particular environment. Mutations are random changes in DNA, and while natural selection cannot create beneficial mutations, it can preserve and distribute them if they provide an advantage in the environment. Harmful mutations may be eliminated through natural selection if they reduce an individual's ability to survive or reproduce. Therefore, natural selection is not a random process but rather a non-random mechanism for evolutionary change.
