Question
The trees on which these moths used to live were white, but now they have been covered in soot from coal factories. Which moth will be more successful in this environment??
- The dark moth
- The light moth
- Both will be successful equally
- Neither will survive
The correct answer is: The dark moth
During the industrial revolution, industries emitted black sooty smoke that turned the trees black due to pollution. This change benefits the black-winged moths as they blend well with the black tree trunks and their number increases.
Hence, dark moths will survive.
