Background of the Peppered Moth
The peppered moth, native to England, originally had a light-colored, speckled appearance, blending with lichen-covered trees. Its history intertwines with the Industrial Revolution, sparking evolutionary changes.
2.1 History of the Peppered Moth and the Industrial Revolution
The peppered moth underwent significant evolutionary changes during the Industrial Revolution. Prior to this period, the moth population was predominantly light-colored, allowing them to blend with lichen-covered tree bark. However, as factories emitted pollutants, tree trunks darkened due to soot, altering the moths’ environment. This shift favored the survival of dark-colored moths, which were less visible to predators on dark backgrounds. This dramatic change illustrates natural selection driven by industrialization.
2.2 The Science Behind Moth Color Variation
The peppered moth’s color variation is genetically determined, with light and dark forms influenced by environmental pressures. The light-colored moths blended well with lichen-covered trees, while dark-colored moths thrived in polluted, darkened environments. This variation allowed natural selection to favor the most adapted phenotype, demonstrating how genetic diversity interacts with environmental changes to drive evolutionary shifts. The moths’ ability to camouflage themselves reduced predation, highlighting the role of adaptation in survival.
