Explain with an example for the given, how the following provides evidence in favor of evolution in organisms :
Homologous organs:- Organs which have the same basic structure but different functions are called homologous organs.
Example:- The forelimbs of a man, lizard, frog, bird, and bat have the same basic design of bones, but they perform different functions. The forelimbs of a man are used for grasping, the forelimbs of a lizard are used for running, the forelimbs of a frog are used to prop up the front ends of the body when at rest and the forelimbs of a bird and bat are modified for flying. Hence, all these organisms use their forelimbs for performing different functions, but the forelimbs have originated from the same structural pattern.
