Homologous organs are structures that share a common evolutionary origin, meaning they have the same basic bone structure despite serving different functions in different organisms. In the case of humans and bats, their forelimbs are built with similar bones (humerus, radius, ulna, etc.) even though humans use them for grasping and bats use them for flying.
