Consider the following hypothetical scenario: An ancestral species of duck had a varied diet that included aquatic plants and terrestrial plants and insects. These include the amount of genetic variation within a population, the number of evolutionary opportunities that a population has, and the number of genetic mutations that occur within a population.
