Darwin considered evolution to be caused due to : 1)small changes/variations that occured 2)these variations were directed specifically towards adapting to the environment(directional) 3)evolution was a slow process De Vries believed that evolution occured by: 1)large changes that occured 2)these changes were mutations and were stochastic or random, not directional 3)evolution occured in fits and starts and was not a slow ongoing process
