Homologous organs are defined as the organs having a similar basic structure or similar anatomy but during evolution they have evolved into different forms for performing different functions. Such structures demonstrate that the organisms have common ancestors. The forelimbs of lizards, flippers of whale, wings of a bat and hands of humans, all share a common set bones i.e. the humerus, the radius and the ulna. But in lizards they are used for locomotion, in whales for swimming, in bat for flying and in humans for performing various different functions such as holding, writing etc. Thus forelimbs of lizards, flippers of whale and wings of a bat are all homologous to hands of humans as they have the same structure but perform different functions.
