Why People Have Tonsils – And Other Useless Body Parts

It’s time to provide answers to one of the most baffling cocktail-party questions ever posed: why do we have extra body parts we don’t really need?

Although the answer is open to debate, even in this age of Wikipedia, the short answer is, “You must be referring to the extra body parts we don’t really need anymore.” Check out this list of “useless” body parts to better understand the way your body works. 


Tonsils are lymph nodes that enforce your immune system exactly where you need them – at the oral entrance way to your body. When tonsils get inflamed or infected, we have them removed, but there are other lymph nodes in the area to do the job.

Wisdom Teeth

Oversized wisdom teeth that crowd your mouth and grow in crooked are a relatively new problem for humans. This stems from the fact that humans simply used to have proportionately larger jaws. Eating cooked and processed foods has made us soft in the tooth and shrunken our jawbones.


Okay, I’ll admit the appendix is a throwback to more primitive times when we foraged for food and ate a lot more greens. As such, it’s known as a vestigial organ. Researchers believe the appendix used to be a magnet for healthy bacteria, but no one really knows.

Men’s Nipples

This one’s easy to answer: we’re all women at the beginning, at least in the embryonic stage. As male hormones take over, men lose many of their feminine traits, but not the nipples. However, without a steady supply of estrogen, men’s nipples will never amount to any practical purpose.


Some medical experts claim the eyebrows exist merely to keep sweat out of our eyes, but many anthropologists insist that eyebrows are an important way we identify one another and show emotion. They’re both right.

Armpit Hair

There’s no mystery under your arms because armpit hair does exactly what’s it’s supposed to – give off a pungent smell. This was a real plus for attracting the opposite sex in caveman days, but in a crowded elevator today, not so much.
