Industrial melanism is an example of:
Industrial melanism is an example of:
- Drug resistance
- Darkening of skin due to smoke from industries
- Protective resemblance with the surroundings
- Defensive adaptation of skin against ultraviolet radiations
The Correct Option is C
Solution and Explanation
Industrial melanism refers to the phenomenon where certain moth and insect populations in industrialized areas have evolved darker coloration to blend in with the soot-covered surfaces of industrial structures, such as tree trunks and buildings. This adaptation provides a form of camouflage, protecting them from predation by visual predators and increasing their chances of survival in such environments.
So, the correct option is (C): Protective resemblance with the surroundings

Evolution
Evolution is a process that occurs in changes in the genetic content of a population over time. Evolutionary change is generally classified into two: microevolution and macroevolution. The process of changes in allele frequencies in a population over time is a microevolutionary process. Three main mechanisms that cause allele frequency change are natural selection, genetic drift, and gene flow. On the other hand, macroevolution refers to change at or above the level of the species.
