A naturalist reads four reports about butterflies.

Which report describes evidence most similar to the evidence Alfred Russel Wallace used when developing the theory of natural selection?

[1]
A

Caterpillars that are given more food develop into adult butterflies with larger wings than others.

B

Wing scales from different butterfly species are compared in fine detail using an electron microscope.

C

A breeder chooses which captive butterflies reproduce, so one wing colour becomes more common in the stock.

D

Closely related butterfly species live on neighbouring islands, but each species is found in a different area.
