The Peppered Moth
About the Peppered moths
Peppered moths are common insects living in England, Europe and North America. They are small moths, there wing span is only 1.5 to 2.5 inches. Peppered Moths are normally white with black speckles across the wings. The colour of these moths mean that they camouflage against lichen on trees, and make them harder to be seen by predators.
This theory states that a species adapts to their environment and passes down a favorable trait. This leads to an evolutionary change within a species. (survival of the fittest). These characteristics give an animal a greater survival or reproductive rate than other animals of the same species and there offspring have inherent these genetic characteristics. He also suggested that humans share a common ancestor with modern apes. The video below goes into further detail about Darwin and his theory of evolution by natural selection
