2. Genetic Drift: It is the random change in the frequency of allels in a population over successive generations.
3. Natural selection: The process by which nature slects and consolidate those organisms which are more suitable adapted and possess favourable variations.
4. Geographical isolation: It is caused by mountain ranges, rivers etc. geographical isolation leads to reproductive isolation due to which there is no low of genes between seprated groups of population.
