  1. Transformation of animals, plants, and other living organisms into different forms by the accumulation of changes over successive generations.
  2. Transmutation of species.
  3. Origination or transformation of an organism, organ, physiological process, biological molecule, etc., by a series of changes.
    Note: The theory of evolution (in general) is the proposition that all living organisms have undergone a process of alteration and diversification from simple primordial forms during the Earth’s history; (in particular) it is a scientific theory proposing a mechanism for this process, now especially that based on Darwin’s theory of the natural selection of genetically inherited and adaptive variation (see neo-Darwinism)
