Evolution is a scientific theory describing change in allele frequency over time. It is also used as shorthand to refer to Charles Darwin's explanation for the diversity of life on earth, stating that all life descended from a common ancestor by the processes of evolution driven by natural selection.
An in-depth study on the subject of evolution is beyond the scope of this wiki. Only those arguments that relate directly to atheism and the existence of God should be cited in articles. For more information, please visit the TalkOrigins website or the Evolution Wiki.
