'''Definitions of evolution''' include (a) "change over time", (b) [[common ancestry]], and (c) the idea that unguided [[natural selection]] acting on random variations and mutations is sufficient to explain the appearance of design.
*"Evolution" can refer to anything from trivial cyclical change within the limits of a preexisting gene pool to the creation of entirely novel genetic information and structure as the result of natural selection acting on random mutations.<ref>(prologue, p. x) [https://www.amazon.com/dp/0062071475/ref=as_li_qf_sp_asin_til?tag=anncoulter-20&camp=14573&creative=327641&linkCode=as1&creativeASIN=0062071475&adid=1QSNY85R152GT1QTA6NH&&ref-refURL=http%3A%2F%2Fwww.anncoulter.com%2F Darwin's Doubt], [[Stephen Meyer]]</ref>
==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 designed for a purpose. "We have design without a designer".
