Vedclass · Answer

(C) In England,before industrialization in the $1850$s,there were more white-winged moths on trees than dark-winged (melanized) moths because the white lichens on tree trunks provided camouflage for the white-winged moths.After industrialization,the tree trunks became dark due to smoke and soot,which killed the lichens.This change favored the dark-winged (melanized) moths as they could hide better against the soot-covered bark,while the white-winged moths were easily spotted and eaten by predators.By the $1920$s,the population of melanized moths had significantly increased compared to the white-winged variety due to this selective advantage.

Select the correct pair regarding the population of moths in the $1920$s.
