The development and events surrounding the theory of evolution can be as interesting as the progress of evolution itself. From the life of Charles Darwin to the various legal battles in America over teaching evolution in public schools, few scientific theories have been associated with as much controversy as the theory of evolution and the idea of common descent. Understanding the timeline of background events is important to understanding evolutionary theory itself.
