'''Definitions of evolution''' include (a) "change over time", (b) [[common ancestry]], and (c) [[natural selection]] acting on random mutation.
==Change over time==
The idea that life now is different from what it was a long time ago is not in dispute (see [[Cambrian Explosion]]).
==Common ancestry==
The idea that all forms of life on the Earth today all derived from the same ancestors is accepted both by mainstream biologists and by proponents of [[Intelligent Design]].
==Mutation and selection==
[[Richard Dawkins]] said that biology is the study of complicated things that give the appearance of having been created for a purpose.
