Male guppies exhibit variations in color, ranging from bright to dull. While the dull guppies camouflage better with the sand, the bright guppies are more attractive to female mates. The chart below shows the distribution of body brightness of male guppies in a population. If a new predator is introduced to the population, how will this most likely affect the coloration of the population over time? The number of dull individuals will increase.

The number of bright individuals will increase.

The bright individuals will develop duller colorations.

The dull individuals will develop brighter colorations.
