Industrial melanism is the phenomenon of the darkening of the skin or fur color of species that live in areas with high levels of industrial pollution. This adaptation is an example of protective resemblance with the surrounding environment.
Explanation:
Industrial melanism is the process by which the frequency of dark-colored individuals in a population increases over time due to natural selection. This phenomenon was first observed in the peppered moth, which had a light-colored wings with dark spots. In the 19th century, when the industrial revolution caused air pollution, the dark-colored moths became more prevalent in areas with high levels of pollution because they were better camouflaged against the soot-covered trees.
The same phenomenon has been observed in other species as well, such as the rock pocket mouse and the Carolina anole lizard. In each case, the darkening of the skin or fur color provides a protective resemblance with the surrounding environment, making it easier for the animals to avoid predators.
Industrial melanism is not an example of drug resistance, as it does not involve the evolution of resistance to drugs or antibiotics. It is also not a defensive adaptation of skin against UV-rays, as the darkening of the skin is not related to UV exposure. Instead, it is a form of protective coloration that helps animals blend in with their environment.
In summary, industrial melanism is an example of protective resemblance with the surrounding environment, in which the darkening of the skin or fur color provides a better camouflage against the polluted environment.
