Homologous organs are found in humans and lizards. The forelimbs of humans and lizards have different functions completely but the basic structure of bones is similar, i.e. they have same origin. Another example is forelimbs of frog and forelimbs of humans.

Analogous organs are found in bat and butterfly. The wings of a bat and wings of a butterfly have similar function i.e. flying but they have completely different origin.
