The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Question**: The question asks about the original study of industrial melanism in moths, specifically identifying the researcher or researchers involved. 2. **Identifying Key Concepts**: Industrial melanism refers to the phenomenon where darker-colored individuals of a species become more prevalent in polluted areas due to natural selection. This is particularly notable in the peppered moth (Biston betularia). 3. **Recognizing the Key Researcher**: The key researcher who studied industrial melanism in the peppered moth is Bernard Kettlewell. His experiments in the 1950s provided significant evidence for natural selection. 4. **Describing Kettlewell's Experiment**: Kettlewell conducted experiments to observe the predation rates of birds on different color morphs of the peppered moth. He found that in polluted areas, the darker moths had a survival advantage because they were less visible against the soot-darkened trees. 5. **Conclusion**: Based on Kettlewell's findings, the correct answer to the question is that industrial melanism in moths was originally studied by Kettlewell. **Final Answer**: The correct option is Kettlewell (Option A). ---

Industrial melanism in peppered moth is an excellent example of natural selection in the recent history'. Justify this statement.

Industrial melanism is one of the most striking example which demonstrates natural selection. After industrial revolution the black coloured form of the peppered moth increased as compared to dull grey or white moth. The black coloured form developed as a result of

Industrial melanism in peppered moth occurred due to natural selection . The significant reason for this is (a) the light coloured white moths could not be noticed by predatory birds after deposition of soots on bark of trees (b) mutation in light coloured moths due to increase in industrial pollution (c) advantageous selection of black moths on tree in polluted areas, resulting in increase population of black moths (d) advantageous selection of white moths on tree in polluted areas, resulting in increased population of white moths
