Natural selection occurs in nature when heritable traits influence the survival and reproduction of organisms over generations, such as brown beetles flourishing while green beetles were selected against. Artificial selection is when humans intentionally breed organisms with desired traits, such as farmers choosing to breed green beetles as their favorite color. The key difference is that natural selection is an unguided process in nature whereas artificial selection involves intentional human choice.
