English Peppered Moth

<p> English Peppered Moth</p><p>Before 1845 most of the peppered moths in Manchester, England were light in color. The light colored moths were difficult prey for birds because they blended with the light-gray bark of the trees. The few black peppered moths stood out in their surroundings and were an easy target for the birds. During this period, there was a large population of light-colored moths and a very small population of dark- colored moths. Beginning in 1845, smoke and soot created by the Industrial Revolution began to darken the bark of the trees. In a period of a few years, the population of light-colored moths fell sharply while the population of the dark-colored moths rose dramatically.
