Four postulates of natural selection
The four propositions underlying Darwin's theory of evolution through natural selection are: (1) more individuals are produced than can survive; (2) there is therefore a struggle for existence; (3) individuals within a species show variation; and (4) offspring tend to inherit their parents' characters. The three necessary and sufficient ...Darwinism, theory of the evolutionary mechanism propounded by Charles Darwin as an explanation of organic change.
