A) Dark moths had a survival advantage in rural Birmingham.
Explanation:
In the given graph, the data about dark moths are colored orange, and the data about light moths are colored green. We can clearly see this in the image I've attached below.
We can see that the percentage of recovered dark moths is greater in Dorset, while the percentage of recovered light moths is greater in Birmingham. This means that the dark moths had a survival advantage in Dorset, while the light moths had the advantage in Birmingham. This is why statement A is not supported by Kettlewell's data.
Answer: The correct answer is-
Natural selection.
Explanation:
Natural selection is an evolutionary theory that was given by Charles's Darwin. According to this theory, organisms that possess a beneficial allele (a gene variant) for their survival or that are capable of adapting themselves in changing environmental conditions, will survive and produce large number of offsprings through reproduction.
Thus, it means that if an organism becomes adapted to its environment, it will survive.
Therefore, Natural selection is the right answer.
