* '''Change in the history of the universe.''' This includes biological change, and non-biological change, such as galaxy formation.  Evolutionist Theodosius Dobzhansky (1900-1975) said, "Evolution comprises all the stages of the development of the universe: the cosmic, biological, and human or cultural developments. Attempts to restrict the concept of evolution to biology are gratuitous."<ref>Quoted by Stephen E.

'''Change in the history of the universe.'''

* '''Descent with modification.''' E.O. Wilson defines, "evolution is any change in gene frequency in a population." This is narrower than the first definition because it just includes biological change, and only those changes which are inherited.
