Life Cycle of the Peppered Moth:
Because their light wings are peppered with small dark spots. Predators of the peppered moth are flycatchers, nuthatches and the European robin. Larvae feed on the leaves of birch, willow, and oak trees. They change into pupae (cocoons) for the winter. They are given the name of carbonaria when black spots are present.
Impact of Pollution:
Near the centre of Manchester during the industrial revolution the first moth was discovered, this was a process on the 19th century in which England especially faced a change and factories were build and they ran by burning coal for fuel, this result on a dark smoke surrounding the countryside, scientists started to study the difference on the color of the moths, and some think they were changing their …show more content…
Scientists test theories by making prediction based on the theory. Then they test the prediction to see if what they observe matches their expectations. Kettlewell did several of this tests predictions on of them being: Heavily polluted forest will have mostly dark peppered moths. Studies showed that most of the population of this dark peppered moths were found near the industrial cities producing pollution. To carry his studies Kettlewell carried out comparison of the data during this time and data carried out time before the Industrial Revolution when dark moths were absent. Based on his studies he concluded that dark moths have a survival advantage as they were less likely to be eaten by birds than the light moths. Then he placed set of moths on clean forests and dark forest and he observed how light moths were more likely to live on clean forests than the dark ones, meanwhile the dark ones were more likely to live on the dark forests. Kettlewell published his finding on Scientific American on
