A bat's wing and a bird's wing are considered __________.
- A. analogous structures
- B. derived traits
- C. homologous structures
- D. vestigial structures
Correct Answer: C. homologous structures
Explanation
A bat's wing and a bird's wing are analogous structures, as the development of these structures does not share an evolutionary history. The common ancestor of bats and birds did not have wings, therefore these traits arose independently. Therefore, they are not homologous, but represent convergent evolution, as similar traits arose from different lineages due to environmental pressures.
