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.

The correct statement that accurately describes the scenario is:
The fish experienced an evolutionary change because of natural selection.
This is because the lighter-scaled fish have a slightly harder time escaping predators, which suggests that the darker-scaled fish had a survival advantage in their new environment, leading to their predominance and the eventual emergence of a new species.
