Camouflage helps organisms to blend with their surrounding so that they can escape predators. Which of the following is an example of camouflage?

Options:
A Biston betularia moths of England
B Darwin finches of Galapagos
C Bacteria growing on penicillin medium
D Lichens growing on trunk of trees

The correct answer is:
Biston betularia moths of England

Solution:
Industrial melanism
- Industrial melanism is an observation made in England that supports 'evolution by natural selection'.

Time of Moth Collection	Observation	Reason behind

The 1850s (Before Industrialization sets in)	On trees, White-winged moths > Dark-winged (or melanized) moths	Before industrialisation, white-coloured lichen grow and almost covered the trees because of which white-winged moth survived due to white background the but the dark-colored moth was more spotted and picked up by the predators.

The 1920s (After Industrialization)	On trees, Dark -winged moths > White-winged moths	Lichens do not grow in polluted areas, so the dark moths were able to camouflage (hide in the background) themselves against the tree trunks became dark due to industrial smoke and soot. Thus they survived in more numbers. White-winged moth were more spotted and picked up by the predators in comparison to the dark-winged.
