Answer:

The forearm of birds, reptiles, and humans illustrates a homologous body structure.
- Similar physical characteristics found in species with a shared origin are known as homologous structures, although these characteristics have entirely different biological purposes.
- The limbs of humans, cats, whales, and bats are examples of homologous structures.
- All of these structures—arm, leg, flipper, and wing—are supported by the same type of bone structure.
- The arms of a person and the wings of a bat are excellent examples of homologous structures. Because both bats and people are mammals, they have a common ancestor.
- Even though they appear considerably different from one another from the outside, a bat's wing and a human arm have remarkably comparable internal bone structures.
- Wings help bats fly, whereas arms enable human interaction with their environment. The wing and the arm also have various purposes.
