In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection The theory of evolution is based on the idea that all species are related and gradually change over time

Broadly defined, biological evolution is any heritable change in a population of organisms over time Changes may be slight or large, but must be passed on to the next generation (or many generations) and must involve populations, not individuals
