The correct answer is to perform the same function in both animals but is anatomically very different.Concept:Evidence for evolution:?FossilsAnalogous and homologous organs Embryological evidence Anatomy: It refers to the internal structure of an organism. Explanation:Homologous organs:These organs are similar in origin and structure but perform different functions.For example, the Forelimbs of frogs, lizards, bats, and humans have the same basic structural plan but different functions.The wings help in flight whereas the human forearm helps in various activities.Analogous organs:These organs have similar functions but are different in structure and origin.For instance, the wings of a bat and a bird are similar in function, but this similarity does not mean that these animals are more closely related. The wings of a bat are just the folds of skin that are stretched between its fingers whereas the wings of birds are modified forearms covered in feathers. Thus, we can say that analogous organs perform the same function in both animals but are anatomically very different.
