Question

What function is performed by human arms, forelimbs of dog and forelimbs of whale?

Answer 1

The human arm's role is to reach items with your hands. The dog's forelimb role is to help with motion. Whale forelimbs act as flippers and operate in turns to stabilize the body and help. Human arms, dog forelimbs and whales forelimbs are homologous organs. Some bodies in structure and origin are essentially the same, but altered to conduct distinct tasks in distinct species. They are called organs that are homologous. These anatomical similarities provide proof of a common ancestor's evolutionary descent of the species.
