The front leg of a cat, the front flipper of a dolphin, and the wing of a bat have the same structure and order of bones. These structures do not look alike and are not used in the same way, but their bones are similar. What might scientists say about the cat, dolphin, and bat based on this evidence

The bones are homologous structures

Explanation:

Homologous structures are the structure which are found similar in appearance in different organisms.

The homologous structures in different organism shows that they shared a common ancestor or they diverged from a common ancestor during course of evolution that is these homologous structures are the result of the divergent evolution.

In the given question, the bat, dolphin and the cat shows the same structure of bone which indicates that they have evolved from a common ancestor and is true as they all belong to mammals.

Thus, the bones are homologous structures is correct.
