Question

In England after industrialisation, the population of dark winged moths were more favoured than white winged moths. Explain.

Hint:

Camouflage is an important evolutionary trait that enhances survival in changing environments.

Answer 1

Industrialisation led to soot coating trees, rendering dark-winged moths less conspicuous to predators than their white-winged counterparts. Consequently, dark-winged moths gained a survival edge, resulting in population growth.
