Explanation:
Natural selection; Natural selection is the process through which populations of living organisms adapt and change. Individuals in a population are naturally variable, meaning that they are all different in some ways. This variation means that some individuals have traits better suited to the environment than others.
Weaker animals within a breed being killed off for food for another species, the surviving animals breed and continue the better genes for survival.
Artificial Selection; Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations.
Corn. Larger growing corn was taken for more growth while smaller were eaten and not continued. Humans decdied the larger pieces were better for food.
