Question

In terms of evolution, what is the significance of homology between a human hand and a wing of a bird?

Answer 1

Homologous organs perform different functions but are similar in origin.

For instance, the wings of birds and forelimb of a person do not look alike but the skeletal structure for both is same.

Thus we can see that they are performing different functions like helping in flight and helping in doing various activities respectively but their origin is same.

Answer 2

Wings of birds & arms of humans are homologous organs as they are same in form but perform different functions like wings help birds to fly whereas arms allow humans to do various activities. The similarities in their skeletal structure is an evidence of their homology & shows they are emryologically similar.
