Why do you think it is necessary for there to be variation in a population in order for evolution by natural selection to occur?

Without variation in the population there will be no differences in relative fitness/differential reproductive success between individuals as a result of natural selection. Without differences in relative fitness between individuals there will be no change in frequency of alleles in the population overtime.

Variations in the population are necessary because it allows some individuals to acclimate to the environment while sustaining the survival of the population.

What do you mean by Genetic variations?

Genetic variations may be defined as the existence of differences in sequences of genes between individual organisms of a species.

Natural selection randomly favors or unfavors one genotype at a time. If there will not be any genetic diversity, it may lead to either extinction or population explosion of a particular genotype.

The genetic variations also depend on the relative fitness of a particular species. In order to resist at least one genotype of given species, genetic variations are important.

Therefore, variations in the population are necessary because it allows some individuals to acclimate to the environment while sustaining the survival of the population.
