The four main ideas of Darwin's evolutionary theory are variability in populations, overproduction of offspring, competition for resources and inheritance of traits. Variation provides advantages to some members of a population. The surviving individuals pass their traits to the next generation. 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 …Darwinism, theory of the evolutionary mechanism propounded by Charles Darwin as an explanation of organic change.
