What are homologous and analogous organs? Explain by giving examples.

1.	What are homologous and analogous organs? Explain by giving examples.
Answer» Term Homlogous was introduced by Richard Owen. The organs which have the same fundamental structure but the different in functions are called Homologous organs. These organs follows the same basic plan of organisation during their development. But in adult condition, these organs are modified to perform different functions an adaptation to different environments. The homologus organs are a result of divergent evaluation. Homology indicates common ancestry. Examples:- Fore-limbs of whole, cheetah and man represent the similar structure of bones like Humerus, Redulna etc. Analogous organs are those organs which have similar functions but are defferent in their structural details and origin. Such organs are the result of convergent evolution. Examples- Wings of insects and wings of birds. Fins of fishes and Flippers of whales.
