To observe natural selection's effects on a population, one must observe more than one generation of the population, which is provided by option A. Additionally, the population must contain genetic variation, which is provided by option B. Therefore, the correct choice is E as it satisfies both conditions required for observing natural selection's effects on a population. Option C is not necessary for observing the effects of natural selection on a population as it does not necessarily imply genetic variation or observable changes in the population over time.
