Consider the following scenario:
Some fish in a murky underground lake have lighter scales than the others. This makes it slightly harder for the lighter fish to escape detection by predators, but most light-colored fish live long enough to reproduce. A natural event separates the dark-scaled fish from their light-scaled cousins, and as a result, a new species of dark-scaled fish emerges.
Which statement accurately describes the scenario?
