Recognize the specific study related to the peppered moths: The peppered moths are a classic example of natural selection observed in nature, where changes in the moth population were linked to industrial pollution.
Research the scientist who conducted experiments on the peppered moths: H.B.D. Kettlewell is known for his experiments in the 1950s that provided evidence for natural selection in the peppered moths.
Conclude that H.B.D. Kettlewell proposed the peppered moths as an example of natural selection based on his experimental work.
