Industrial melanism is an example of
0%
a) natural selection
0%
b) mutation
0%
c) adaptive convergence
0%
d) artificial selection
Explanation
Industrial melanism is an adaptation where the moths living in the industrial areas developed melanin pigment to hide themselves from their predators. Hence, moths that were able to camouflage themselves, i.e., hide in the background, survived (Figure 7.4). This understanding is supported by the fact that in areas where industrialisation did not occur e.g., in rural areas, the count of melanic moths was low. This showed that in a mixed population, those that can better-adapt, survive and increase in population size. Answer : (a)
