7 ‘Useless’ Body Parts Explained : What You Do And Don’t Need.

From mens’ nipples to wisdom teeth – here are seven body parts you really don’t need.


why do men have nipples

Why do men have nipples anyway? Because all men start off as women. All human fetuses develop nipples even before our gender is determined. Nipples are the same in men and women, but without an influx of hormones like estrogen, they’re simply chest ornaments on men.


While the appendix is found between the small intestine and large intestine it plays no role in digestion. Experts suggest it may have served a purpose when the human diet was mostly made up of plants. Now it only becomes inflamed and infected before finally rupturing when someone develops appendicitis.


Other than being extremely painful to remove, wisdom teeth serve no purpose with the exception of misaligning our jaw and impeding on dental hygiene. Today, around 35 percent of the population no longer develops their third and final set of molars.

4. Eyebrows

Eyebrows are a debatable organ. Some feel they were once there to help our ancestors navigate and hunt. While a few experts believe, eyebrows are a mode of identification today. Aside from using them for expression, they even protect our eyes from debris, water and sun. Thus, eyebrows come under the debatable group of useful or useless body parts.

5. Armpit Hair

There’s no definitive story for underarm hair, but its location offers a clue. There are two types of sweat glands in your body: eccrine and apocrine, the latter of which are mostly in your armpits. You use apocrine for sexual signaling. Presumably, the hair holds on to the secreted odors so they’ll stay around long enough for a potential mate to catch a whiff, he explains.

6. Tonsils

Tonsils are technically lymph nodes–part of the lymphatic system, which is vital to your immunity. Tonsils protect our body from bacteria and viruses that enter through the nose and mouth but they can also be infected with too much exposure to these bacteria. They may serve as warning signals for our body.

7. Pinky Toe

The fifth toe on your feet was once used by apes to grab trees and swing around. Today, all one needs is the big toe and the three neighboring pinkies. The tiny one remains for cosmetic reasons.
