The bones of forelimbs of whale, bat, cheetah and man are similar in structure, because
1. one organism has given rise to another

Viviparity is considered to be more evolved because
1. | the young ones are left on their own |
2. | the young ones are protected by a thick shell |
3. | the young ones are protected inside the mother's body and are looked after they are born leading to more chances of survival |
4. | the embryo takes a long time to develop |
