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.
Evolution can loosely be defined as genetic change over time, but there is much more to it than that.
Both fossils from long ago and organisms alive today provide evidence for evolution and help us to better understand how the process works.
