No. 1 - Male Nipples
Because, why?
No। 2 - Appendix
Darwin claimed the appendix was useful for digestion during our early plant-eating years; it's dwindled down to little since we started eating more digestible foods.
No. 3 - Wisdom Teeth
Back in the day, when we ate mammoth meat off the bone and didn't floss afterward, our teeth tended to fall out. Therefore, when those reserve molars, aka "wisdom teeth," came in they were welcomed. Nowadays, fluoride and dental plans have just made them a huge pain.
No. 4 - Erector Pili
When were hairier (see No. 9), the erector pili made the hairs stand on end when we needed to appear bigger and scarier. Now, it just gives us goose bumps.
No। 5 - Coccyx
More useful as a game-winning Scrabble word than part of the anatomy, the coccyx, or tailbone, is several fused vertebrae left over from the olden days when we had tails.

No. 9 - Body Hair
You may not know it, but you have a third eyelid. Pull open the two more noticeable eyelids and take a look - it's located right in the corner by the tear duct. The third eyelid is left over from what's known as a "nictitating membrane," which is still present in animals like chickens, lizards and sharks.
No. 10 - Plica semilunaris (third eyelid)
You may not know it, but you have a third eyelid. Pull open the two more noticeable eyelids and take a look - it's located right in the corner by the tear duct. The third eyelid is left over from what's known as a "nictitating membrane," which is still present in animals like chickens, lizards and sharks.
