Explanation:

The change or transformation of a caterpillar into a butterfly is known as Metamorphosis. A butterfly has four stages in its life-cycle. They are, eggs, caterpillar or larva, pupa and adult butterfly. Therefore, the metamorphosis of a caterpillar into a butterfly forms a part of its Life-cycle.Horses becoming taller and faster over millions of years, increase in size of human brain and different species of tortoise in Galapagos island which descend from a common ancestor are examples of Adaptation. Adaptation can be defined as the phenomenon due to which organisms undergo various types of physical, biochemical, physiological and metabolic changes in them over long periods of time by the process of evolution in order to adjust themselves to the environment they are exposed to in the best possible manner.A feature that allows an organism to better survive in its environment is a(n): Adaptation.
