Answer: This moth has evolved
Step-by-step explanation:
Evolutionary patterns show different patterns. One of the patterns is that: one species gradually transform into another species.
The above mentioned pattern is responsible for the moth's ability to lay more eggs and have more surviving offspring than other moths in the area. The moth is gradually transforming, so also its offspring will inherit these new traits, and it would further demonstrate evolution of one species.
Thus, it can be concluded that the unique ability of this moth over other moths is because the moth has evolved.
