Question
How do homologous organs represent divergent evolution? Explain with the help of a suitable example.

Organs with similar strucuture/same ancestry/anatomically same/same origin developed along different directions due to adapation/different needs, to perform different functions.

For example the fore limbs of some animals (Vertebrates) like whales, bats, cheetah and human have similar anatomical strucuture (i.e. humerus, radius, ulna, carpals, metacarpals and phalanges) develop differently to meet different needs/to perform different functions.
