There are five animals A, B, C, D and E. The animal A uses its modified forelimbs for flying. The animal Buses its forelimbs for running whereas the animal C uses its forelimbs for grasping. The animal D can live on land as well as in water and uses its forelimbs to prop up the front end of its body when at rest. The animal E which respires by using spiracles and tracheae uses wings for flying but its wings are analogous to the modified forelimbs of animal A.
State whether animals A and E have a common ancestor or not.
