Question

Define the homologous organs with two examples?

Answer 1

Homology refers to the traits inherited by two different organisms from a common ancestry. Organs such as bat's wing, wings of birds, seal's flipper, forelimb of a horse, and human arm have a common underlying anatomy that was present in their last common ancestors; therefore their forelimbs are homologous organs.

Answer 2

Organs which have same structure but different functions are known as homologous organs.The arm of a human, the wing of a bird or a bat, the leg of a dog and the flipper of a dolphin or whale are homologous structures.
