Evolution is a gradual and continuing process of change that occur over a period of time, due to slight variations in genetic compositions as well as changes in environment, leading to formation of new species. Several processes like geographical isolation, genetic drift, mutation and natural selection play an important role in bringing about the evolution and speciation.
