Are the limbs converted into wings of bats and the wings of bird’s illustrations of evolutionary homology or analogy? What regarding whale fins compared to the fish fins?
Expert
Bat and bird wings contain similar function and similar origin (they are converted limbs) therefore they are homologous and analogous organs. The Whale fins are a modification of posterior limbs whereas fish fins though containing similar function does not come from modified limbs; therefore they are analogous however not homologous structures. Evolutionary homology recommends common ancestry whereas biological analogy associates to the concept of evolutionary convergence, the appearance of identical features in evolutionarily distant species which explore similar kind of environment.
