Detailed explanation-1: -The correct answer is analogous organs. The organs that have different basic structures (or different basic designs) but have a similar appearance and perform similar functions are called analogous organs.

Detailed explanation-2: -Analogous organs are those organs that have some superficial resemblance, perform similar functions and yet, have different evolutionary origins and hence, different anatomical structures.

Detailed explanation-3: -Complete Step by Step Answer: Homologous organs perform the same function but are structurally different. The structure of the vertebrae is a common homologous structure in all mammals. Human beings are related to dinosaurs by an auditory bone that exists inside the human ears is homologous to a dinosaurs’ jawbone.

Detailed explanation-4: -They have a different ancestral origin and hence do not have a shared common ancestor. Examples of analogous organs are wings of birds and butterflies, flippers of Penguins and Dolphins, eyes of the octopus and of mammals, sweet potato and potato.
