Peppered Moths
Before the Industrial Revolution there were more sightings of light-colored moths and
fewer sightings of dark-colored moths. As factories were built during the Industrial
Revolution, pollution increased. At this time, scientists observed that the number of
light-colored moths decreased, while the number of dark-colore moths increased and
became more abundant in the population than the light-colored variety.
Which graph represents how natural selection acted on moth coloration during
the Industrial Revolution? The dotted line represents the original population and the
solid line represents the population after selection.
