Question

which of the following does not contain structures homologous to the human arm? tiktaalik fin dragonfly wing turtle flipper bird wing bat wing

Explanation:

Homologous structures share a common embryonic origin. The human arm, Tiktaalik fin, turtle flipper, bird wing, and bat wing are all tetrapod structures with similar bone arrangements from a shared ancestor. Dragonfly wings are insect structures (arthropod exoskeletons) with no common embryonic origin to the human arm, so they are not homologous.

Answer:

dragonfly wing
