Some animals display the ability to camouflage while others have interesting defense mechanisms that protect them from predators. The spots on the snow leopard, for example, did not emerge overnight. This pigment helps to absorb the heat and protects the nucleus, thus protecting the DNA from mutation due to UV radiation. U.S. scientists have used laboratory techniques and sediment cores from the ocean to help explain the how rivers have changed course over millions of years. An adaptation is a characteristic of a living thing that helps it survive in its environment. Majority of aquatic animals are streamlined which helps them to reduce friction and thus save energy.

Clift and Blusztajn believe the change is caused by a rerouting of the major rivers of the Punjab region into the Indus River, where they flow into the Arabian Sea west of India. The adaptation of animals and plants to their environment is a series of varied biological processes with varying purposes, but the general purpose is the continued survival of the species. These adaptations might make it very difficult for the plant to survive in a different place.
