Answer:
They are homologous structures.
Explanation:
The bat's wing and the dolphin's flipper are homologous structures. Their wings and flippers have differences in terms of their appearance because they are different animals. Although, these structures have the same form and function because the bat and dolphin got it from a common ancestor that has limbs. The homologous structures show evidence that organisms shared a common ancestor, most probably 60 million years ago. An example of a homologous structure is the forelimb of a whale, a human, and a dog. Homologous structures have the same structure, but may have a different function. Homologous structures indicate a common ancestor. A homologous structure is an organ or bone that's in common between different animals that demonstrates an anatomical commonality indicating that the animals share a common ancestor.
