Question

Which one is not vestigial in humans?

• A. Third molar
• B. Coccyx
• C. Segmental abdominal muscles
• D. Finger nails

Answer 1

The correct option is D Finger nails

Our fingernails are proportionately indistinguishable size from our wild partners, they are not decreased structures. Despite everything, they keep up their unique capacity so they are not decayed or functionless. It is critical to contrast our fingernails with those of our nearest relatives - chimps, orangutans, or even monkeys - as opposed to something like a tiger hook which is a specific structure.

So, the correct option is 'Fingernails'.
