Theory of evolution that represents a synthesis of Charles Darwin's theory in terms of natural selection and modern population genetics.

The term was first used after 1896 to describe the theories of August Weismann (1834–1914), who asserted that his germ-plasm theory made impossible the inheritance of acquired characteristics and supported natural selection as the only major process that would account for biological evolution.
