Rock pocket mice are rodents native to the southwest. Normally, the rock pocket mice are tan colored rodents living in the sandy environment of the west. However, a mutation introduced an allele for dark fur. Scientists are now studying the populations of tan pocket mice living in the sandy environment along with the mutant black mice thriving on dark lava rock from an old lava flow. The rock pocket mice are living examples of evolution occurring today. Which of these statements DOES NOT support that idea?

A) Organisms develop mutations to help them survive.


B) Mutations that increase the fitness of an organism increase in frequency in a population.


C) The selection pressure can be different depending on the particular environment.
