Both artificial selection and natural selection involve the selection of individuals that have favorable traits for enhanced survival and reproduction. Organisms that have certain traits survive better than others that lack these traits and therefore their reproductive output is greater. Natural selection differs from artificial selection in that it is a completely random process with no predetermined outcome of the selective process.
