Answer in Brief

How are variations useful for species if there is drastic alteration in the niches?

Solution

If the niche were drastically altered, the population could be wiped out. However, if some variations were to be present in a few individuals in these populations, there would be some chance for them to survive. Variation is thus useful for the survival of species over time.
