Title: Why is genetic variation necessary to the process of natural selection and therefore evolution? Post by: riyaz on Jan 29, 2013 Because if there is no variation, then all individuals in every generation must have the same genome. So there can be no change from generation to generation in the relative proportions of heritable characteristics present in the population. Such change is the definition of evolution.
