Early elephants that were unable to adapt to dramatic environmental changes became extinct. How did some elephants survive the changes?
A.
The elephants’ skulls became shorter and the jaw higher on the ancestors of modern elephants. They underwent evolutionary adaptation. This physical change allowed the elephants to eat a new diet as the environment changed.
B.
Ancestors of modern elephants developed a darker skin color due to a change in food. The darker skin color allowed them to be more prone to damage from the sun.
C.
The elephants underwent a mutation for protection from parasites in the new environment. They evolved larger ears because of this.
