The theory of evolution states that the diverse array of organisms on Earth has evolved from a single common ancestor over time. Evolution works through a process known as natural selection. Natural selection makes it more likely for the best-adapted individuals to survive and reproduce. Individuals who reproduce pass their traits on to their ...
