PEPPERED MOTH SIMULATION

PEPPERED MOTH SIMULATION. The evolution of the peppered moth over the last two hundred years has been studied in detail. The vast majority of peppered moths had light colouration, which effectively camouflaged them against the light-coloured trees and lichens which they rested upon.

  1. PEPPERED MOTHSIMULATION

  2. The evolution of the peppered moth over the last two hundred years has been studied in detail. • The vast majority of peppered moths had light colouration, which effectively camouflaged them against the light-coloured trees and lichens which they rested upon.

  3. Industrial melanism is a term used to describe the adaptation of a population in response to pollution. • One example of rapid industrial melanism occurred in populations of peppered moths in the area of Manchester, England from 1845 to 1890. • Before the industrial revolution, the trunks of the trees in the forest around Manchester were light due to the presence of lichens. Most of the peppered moths in the area were light colored with dark spots. As the industrial revolution progressed, the tree trunks became covered with soot and turned dark. Over a period of 45 years, the dark variety of the peppered moth became more common.
