So it is natural that hearing would operate differently in the ocean than on land. The change in the environment favors certain adaptations over others. This causes evolution. If you trace the evolution of the internal ear of whales through its various ancestors, you can observe the evolutionary pattern from land to sea. Such auditory transitions have not occurred in humans, meaning that our hearing is far less useful underwater.
