Adaptation refers to a change in an organism's structure and function as a result of a natural process that makes the organism more suited to endure and proliferate in a given environment. Adaptation occurs in plants and animals, allowing them to adjust well within a given environment. E.g. Dessert plants like cacti have spikes, which allows them to conserve water. Animals like tigers have stripes on their body which help them to blend well with their environment like grasslands in order to catch prey.

What is Adaptation?

The natural process through which organisms adapt to completely new surroundings or fluctuations in their current environments is known as adaptation. Georges Louis Leclerc Comte de Buffon was one of the scientists who investigated adaptation before the creation of evolutionary theory. He was a French mathematician who held the view that creatures evolved over time by adjusting to their circumstances.
