    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.

    When a section of population get isolated or migrated or drifted from original population, then this section becomes genetically different from the original population due to change in allelic frequency because gene pool of this section may contain some alleles in Avery low frequency or may lack a few alleles. Sometimes change in allelic frequency is so different in the new sample of population that they are become a different species. The original drifted population becomes founders and the effect is called founder effect
