3. Individuals continuously compete with each other for food, space, and light.
4. The one which is more fit than the other gets naturally selected, survives, and reproduces.
5. The process of getting selected by nature is known as natural selection.
6. So, fitness is the end of the capability to adapt and get selected by nature.
