Question

What function is performed by human arms problems of dogs and forelimbs of waves?

Answer 1

The function of the human arm is to be able to reach objects with your hands. The function of forelimb of dog is to assist in movement. The forelimbs of whales act as flippers and function to stabilize the body and aid in turns.

Human arms, forelimbs of dogs and forelimbs of whales are homologous organs. There are some organs that are fundamentally same in structure and origin, but are modified to perform different functions in different organisms. They are called homologous organs.

These anatomical similarities provide the evidence for the evolutionary descent of the animals from a common ancestor. Modifications for different purposes have occurred through time, but the supporting bones remain the same.
