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 conclusion is drawn from the fact that lighter-scaled fish have a harder time escaping detection by predators, suggesting that their coloration affects their survival and reproduction rates. Over time, this differential survival may lead to the emergence of a new species of dark-scaled fish, indicating a process driven by natural selection.
