    Natural selection is the only mechanism for evolution recognized during Darwin's lifetime. c. Evolution can be used to justify immoral behavior, violating natural law. d. Science assumes that only natural causes operate and rejects supernatural intervention. e. A literal reading of the bible is incompatible with modern knowledge of the natural. Natural selection, orthogenesis and Lamarckism all play prominent roles, which have waxed and waned in popularity throughout this time. The progress of theories of evolution is seen in the context of developments in other areas of biology, and also other sciences such as palaeontology, geology and physics as well as broader cultural by:
