Question

Which of the following animals is a 'living fossil'?

• A. Limulus
• B. Neopilina
• C. Both A and B
• D. None of the above

Answer 1

The correct option is C Both A and B

Coined by Charles Darwin, the term 'living fossils' is used to describe living creatures that have remained largely unchanged for millions of years.

Limulus is also known as 'horseshoe crab'. It is one of the very few animals that is still around. Fossils of them date back to 500 million years and these creatures is also present now.

Neopilina shares a close relationship with fossils that existed about 400 to 500 million years ago.

Hence, option C is correct.
