Client 1 - Charles Robert Darwin (1809-1882)

English Naturalist

Darwin's Theory of Evolution is a slow gradual process:

Darwin wrote, "…Natural selection acts only by taking advantage of slight successive variations; she can never take a great and sudden leap, but must advance by short and sure, though slow steps." [1] Thus, Darwin conceded that, "If it could be demonstrated that any complex organ existed, which could not possibly have been formed by numerous, successive, slight modifications, my theory would absolutely break down." [2]
