Question

Which one of the following set of structures includes only analogous organs?

• A. Hind legs of horse, grass hopper and bat
• B. Hands of man, monkey and kangaroo
• C. Mandibles of cockroach, mosquito and honeybee
• D. Wings of butterfly, housefly and bat

Answer 1

The correct option is D Wings of butterfly, housefly and bat

Analogous organs perform same functions but they belong to different origins. An example of an analogous trait would be the wings of the butterfly, bats, and housefly that evolved independently in each lineage separately after diverging from an ancestor without wings. The wings of butterfly are large and have scales. The wings of the insects originate from the inner or outer surface of the insect’s body. The wings of bats originate from both the forelimb and the membranous skin of the abdomen.

So, the correct answer is option D.
