Imagine That You Are Standing in a Field and You

Imagine that you are standing in a field and you see a group of butterflies. You notice an individual that looks significantly different from the other butterflies in the population. This difference allows the butterfly to escape predation more efficiently than other butterflies in the population. How might this trait have arisen in the individual?

A) There were more predators in the surrounding area, so the butterfly needed the trait in order to escape predation.
B) There were more predators in the surrounding area, so the butterflies allowed themselves to be caught to save the faster butterflies in the population.
C) There was a random mutation in a gene that led to differences in the ability to escape predation.
D) There was a mutation in a gene that led to differences in the ability to attract mates.
