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?

Explanation: a natural event geographically isolated the dark-scaled population, and that isolation (founder effect/allopatric speciation) led to allele-frequency change and a new species by random processes. Nothing in the scenario describes strong differential reproductive success driving adaptation, so it’s not clearly natural selection.
