Question

Which one of the following terms would most correctly describe the relationship between the flight organs of animals like locust, bat, swallow and flying fish?

• A. Atavism
• B. Analogous
• C. Homologous
• D. Vestigeal

Answer 1

The correct option is B Analogous

Analogous organs are those that perform similar functions but have entirely different embryonic origins. An example of an analogous organ would be the arms and legs of tetrapods (amphibians, reptiles, birds and mammals) and the legs of insects. So, the flight organs of animals like locust, bat, swallow and flying fish are analogous organs, as they are used for similar function. Thus, the correct answer is option B.
