Evolution

Overview
Evolution is the idea that the nature of a species can change irreversibly (evolve) over time – a fact which can be directly observed over human timescales, especially in lower life-forms such as bacteria.

The word "evolution" is often used to refer to the scientific theory of evolution by natural selection.
