More technically, evolution is the change in genetic composition of a population over time, specifically over generations, resulting from differential survival and reproduction of individuals. Evolution by natural selection describes one mechanism for this change. WebbDarwin's Theory of Natural Selection has been divided into five parts to explain clearly how evolution happens in nature. 1. Organisms produce more offspring than actually survive. Organisms can die from many causes: disease, starvation, and being eaten, among other things. The environment can't support every organism that is born.

When two species evolve in diverse directions from a common point, it is called divergent evolution.
