Question

Which one of the following is homologous to the wing of a bat?

Options

• Tail of a kangaroo

• Wing of a butterfly

• Tail fin ofa fish

• Arm of a human

Answer 1

Arm of a human

Explanation:

The wing of a bat is homologous to the arm of a human because both have a similar underlying bone structure inherited from a common ancestor, despite serving different functions. Homologous structures indicate common ancestry, whereas analogies (e.g., bat wing and butterfly wing) arise from convergent evolution and serve similar functions but have different structural origins.
