Question 2

How does the creation of variations in a species promote survival?

Answer

Any species is adapted to survive in a particular niche. In case of any sudden change in that niche the species may not survive if all the individuals are alike. But if few individuals are different due to variations they can adapt to the changed conditions and thus species can avoid being wiped out. Therefore, the creation of variations in a species promote its evolution and hence its survival.
