Question

What is the main difference between Darwin's theory of natural selection and De Vries mutation theory ?

Prabhat Rajore · Accepted Answer

The mutation theory differs from Darwin's theory in the nature of the variations. Continuous variations or fluctuations are the raw materials for the formation of new species in Darwin's theory of natural selection, but in De Vries theory, discontinuous variations or mutations are the raw materials. Darwins theory stated that evolution is a gradual process while De Vries stated that the process is sudden.  - Wired Faculty
