Examples of homology or evolutionary analogy

Are the limbs modified in the wings of bats and wings of bird’s examples of homology or evolutionary analogy? What about whale fins compared to the fish fins?

Verified

Bat and bird wings have the similar function and the similar origin (they are modified in limbs) so they are homologous and analogous organs. Whale fins are a modification of posterior limbs while fish fins though having the similar function don’t come from modified limbs; so they are analogous however not homologous structures.

Evolutionary homology suggests general ancestry while biological analogy relates to concept of the evolutionary convergence, the appearance of same aspects in evolutionarily distant species which explore the similar type of environment (in the mentioned case, aquatic habitat).
