Vedclass · Answer

(B) The phenomenon described is industrial melanism, observed in the peppered moth $(Biston 	ext{ betularia})$. Before industrialization, the tree trunks were covered with white-colored lichens. Therefore, white-winged moths were better camouflaged against predators and were more abundant $(P = 	ext{White-winged moths})$. After industrialization, the tree trunks became dark due to soot and smoke, and lichens died. Dark-winged moths (melanic form) were better camouflaged in this environment and became more abundant $(Q = 	ext{Dark-winged moths})$. Thus, the correct option is $B$.

Observations from England support evolution by natural selection. Before industrialization, $P$ moths were more abundant on trees, whereas after industrialization, $Q$ moths were more abundant. Identify $Q$.
