Question

Which one is vestigial in humans?

• A. Pinna muscles
• B. Eye lids
• C. Canine teeth
• D. Nails

Answer 1

The correct option is A Pinna muscles

The auricular, or extraneous, muscles of the human ear incorporate the front auricular muscle, the unrivalled auricular muscle, and the back auricular muscle. Together, they control the pinna or the noticeable piece of the ear. In numerous warm-blooded creatures, ear developments delivered by the auricular muscles assume a job in sound confinement and the declaration of feeling, yet in people, the muscles are viewed as nonfunctional.

So, the correct option is 'Pinna's muscles'.
