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?
1 answer
The lighter scales in the original population of fish were a genetic variation that provided a selective advantage in their environment, leading to the emergence of a new species with dark scales due to a natural event that separated the two populations.
