Answer 2

D - Convergent evolution

A and B have to do with physical/geographic locations of the species involved, and how isolation does or does not affect the changes. The species are in any case related.

C has to do with the rate of radiation, or how quickly different subspecies or related species diversify.

D (convergent evolution) deals with how non-related species can develop similar traits.

Answer 3

the answer is D - Convergent evolution, 'convergent' meaning coming together from different directions.
