The bones of forelimbs of whale, bat, cheetah and man are similar in structure, because
1 One organism has given rise to another
2 They share a common ancestor
3 They perform the same function
4 They have biochemical similarities
Explanation:
The bones of forelimbs of whale, bate, cheetah, and man are similar in structure because they are homologous organs. The organs which have the same fundamental structure but are different in functions are called homologous organs.

Recapitulation theory is suggested by one of the following
1 The young one of bird is ammonotelic but the adult is uricotelic
2 Human embryo and adult have hair
3 The tadpole gills for respiration like fishes but adult frog has no gills
4 Both (1) and (3)
Explanation:
Theory of recapitulation also called biogenetic law or embryological parallelism. It is a theory which tied embryology with evolution. It stated that before they are born, organisms pass through developmental stages that look like adult animals of other species.
