Natural selection is a process of adaptation by an organism to the changing environment by bringing selective changes to its genotype or genetic composition.
Artificial selection, also called selective breeding, is the process where humans identify desirable traits in animals and plants and use these traits to develop desirable phenotypic traits by breeding.
