Homologous organs are those that have the following characteristics:

The properties inherited by two separate creatures from shared ancestors are referred to as homology. Organs such as a bat's wing, bird wings, a seal's flipper, a horse's forelimb, and a human arm have underlying architecture that was present in their last common ancestor; thus, their forelimbs are homologous organs. As a result, the right response is "Same structure, different functions."
