Frogs, birds, rabbits, and lizards all have different forelimbs, which makes sense when you consider their different lifestyles. Interestingly, all of their forelimbs share the same set of bones: the ulna, the radius, and the humerus. These same bones are also seen in fossils of the extinct animal Eusthenopteron, which demonstrates common ancestry among these four groups of animals. Hence, these forelimbs are an example of:

Respuesta :

Answer:

Homologous organs

Explanation:

The forelims of frogs, birds, rabbits and lizards are adapted to perform different functions as per the lifestyle of these animals. But forelimbs in given animals are made of same type and pentadactyl pattern of bones. The forelimbs of frogs, birds, rabbits and lizards are thus, homologous organs. Their origin is the same but perform diferent functions. This is an evidence of divergent evolution and these animals share common ancestory.
