Answer: Structures as different as horse hooves, bat wings, and whale flippers contain pentadactyl bones that develop from the same embryonic tissues. This has been interpreted by the evolutionary biologists by proposing that all of them share a common ancestary. The presence of penyadactyl limb is a sign of homology in the pre-Darwinian sense. The presence of homology in the limbs suggest that they share a common ancestry and thus, the correct option is A.
