how does creation of variation in species promote survival?
Asked by VAIBHAV SRIVASTAVA | 3rd Jan, 2013, 09:45: AM
Variation is useful for the survival of species over time. If a population of reproducing organisms were suited to a particular niche and 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 may be some chance of their survival.
E.g.: If the temperature of water increases by global warming, most bacteria would die. But a population of heat resistant bacteria could survive here. These few variants would be resistant to the heat andwould survive and grow further.
