The principle of evolution include: (1) the origin of the diversity of living organisms; (2) the origin of adaption of organisms to their environment; and (3) differences in structure between living organisms. Charles Darwin was the first person to give the world strong reasons for believing that plants and animals had evolved.

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.

Although the theory of evolution generated some controversy when it was first proposed, it was almost universally accepted by biologists, particularly younger biologists, within 20 years after publication of On the Origin of Species. Nevertheless, the theory of evolution is a difficult concept and misconceptions about how it works abound.In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.

Technically, evolution is not a theory, but there are theories (or is a theory) of evolution. There is the fact of evolution, which makes it correct to say that evolution is a fact; but after that, it’s a question of how it works. For that, we have theories of evolution.In his major book published in 1944, Tempo and Mode in Evolution, Simpson divided evolutionary change into "tempo" (rates of change) and "mode" (manner or mechanism of change) with tempo a regulating factor of mode. Simpson's primary contention was that the fossil record clearly and inarguably supports Darwin's theory of natural selection.

Evolution by natural selection occurs when certain genotypes produce more offspring than other genotypes in response to the environment.
