Evolution.It is generally accepted that the astonishing diversity of life on our planet is the result of a process called evolution, which drives organisms to change gradually over time. While the basic concept of organisms evolving is not a difficult one, understanding how evolution works, and how evolutionary theory was developed, is more complex.
