The evolutionary story of moths in England during industrialisation reveals, that 'evolution is reversible'. Clarify this statement.
Answers (1)
White-winged moths thrive in tree trunks with a white background, but when the tree trunks become dark, the white-winged moths perished. Post industrialisation, tree trunks turned dark due to pollution leading to a drop in the population of white-winged moths. In this scenario, dark-winged moths reappeared and survived. Thus, the evolution of white wings was reversed because of pollution. This shows that evolution is apparently reversible.
