Show Hint
Industrial melanism is an adaptation in which the moths living in industrial areas develop melanin pigments in order to match their body to the soot-covered surroundings.
- mutation
- Neo-Lamarckism
- Neo-Darwinism
- natural selection.
The Correct Option is D
Solution and Explanation
Industrial melanism is an adaptation in which the moths living in industrial areas develop melanin pigments in order to match their body color to the tree trunks or soot-covered surroundings. It is an example of natural selection. The peppered moth exists in light and dark strains.
- Natural selection results from differential reproduction (some members of a population produce abundant offspring, some just a few while others none) in the same population.
- Industrial melanism is evolution by natural selection.
Hence, Industrial melanism is an example of natural selection.

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.
