Question

Professor PC Thomas Classes · Answer

(a) : Hugo de Vries (1901) put forward a theory of evolution, called mutation theory. The theory states that evolution is a jerky process where new varieties and species are formed by mutations (discontinuous variations) that function as raw material of evolution. Mutations appear all of a sudden. They become operational immediately. Mutations appear in all conceivable directions.
