Detailed explanation-1: -On the basis of above observations, 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.

Detailed explanation-2: -According to de Vries’ mutation theory, living organisms can develop changes to their genes that greatly alter the organism. These changes are passed down to the next generation, and lead to the development of new species. Once a new species has evolved, it becomes fixed and stops changing.

Detailed explanation-3: -De Vries was also a strong proponent of the idea of discontinuous variations. De Vries believed species evolve from other species through sudden, large changes of character traits.

Detailed explanation-4: -Final Answer: The mutation Theory of Evolution was proposed by Hugo de Vries.

Detailed explanation-5: -Complete answer: Hugo de Vries was a Dutch botanist who gave the concept of mutation theory. He experimented on evening Primrose. He studied that new traits can be inherited that were not previously present in the ancestors.
