What does the observation of moth populations in rural areas without industrialization support?
Options
- AThe idea that all variants are completely wiped out over time
- BThe concept that pollution directly causes genetic mutations in moths
- CThe notion that only moths with melanic coloration are beneficial
- DThe principle that those better adapted to their environment will survive and increase in population size
Correct answer
D. The principle that those better adapted to their environment will survive and increase in population size
Step-by-step solution
The observation supports the principle that moths that were better adapted to their environment (i.e., camouflaged effectively) survived and increased in population size, while less well-adapted variants were less successful .During post- industrialisation period, the tree trunks became dark due to industrial smoke and soots. Under this condition the white-winged moth did not survive due to predators, dark-winged or melanised moth survived. Before industrialisation set in, thick growth of almost white-coloured lich
