Question

Scientists genetically modified a specific subspecies of fruit flies to ensure there are no mutations when DNA replicates. The scientists state this modification will wipe out any genetic variation in these particular modified flies. The second set of scientists make the claim that getting rid of errors during the S phase of mitosis will not entirely get rid of genetic variation in these fruit flies your job is:

Explain how does variation leads to this population's evolution?

Please be specific and thorough as possible, I will give a thumb up if I like your answer. Thank you.
