Correct Answer:
Natural Selection
- Case Study: The Peppered Moth (Biston betularia) in England underwent a dramatic shift in population frequency.
- Before Industrialization: Most moths were light-colored, blending with lichen-covered trees.
- After Industrialization: Soot covered the trees, favoring the survival and reproduction of rare dark-colored (melanic) moths.
- Mechanism: This 'Industrial Melanism' is a textbook example of Natural Selection in action within a short timeframe.
- Conclusion: It represents natural selection.
