Question
Natural selection favored melanic moths to survive in industrial areas because?
- The tree trunks were light in color.
- The dark tree trunks camouflaged the dark moths.
- Robins ate most of the dark moths.
- The speckled moths bred with the darker moths.
Hint:
Natural selection.
The correct answer is: The dark tree trunks camouflaged the dark moths.
Rather than causing the black color mutation, the sooty conditions of the Industrial Revolution created the perfect backdrop for black moths to survive. As soot covered surfaces throughout Britain, black moths blended in with their background, escaping notice by predators and thriving.
