Human beings are a patchwork of new and freshly evolved organs and body parts that are coupled with a lot of old “vestigial” throwbacks. The process of natural selection has caused human beings to evolve in an odd way that forces our “old parts” to take on new jobs without getting rid of them. Because of this, there are several parts of your body that don’t make sense for any of several reasons, most notably; structurally, environmentally, and physiologically. But since when has being human had anything to do with sense? Our body’s cells routinely do radically bad things to themselves for no good reason other than to just do it. So that’s as good a place to start this list of Stupid Human Parts as any other place I can figure…
1. Cells
Cells themselves are ridiculous in the fact that sometimes they actually fight each other. This leads to any number of diseases that are detrimental to the rest of the body. Unfortunately for us, cells are the building blocks of our whole body, so we aren’t going to be replacing them anytime soon…unless somebody buys me the cyborg on my wish-list.
2. Backs
Our backs were created to sustain weight and were given a curve to support that weigh much like a bridge will bend in the middle. Stupidly, humans decided to stand and walk upright, destroying any help having a curved back might give us. Not only did we trade in strength and stability for the ability to stand up and see predators, we also opened the door for thousands of years of old people complaining.

We might get bad backs, but we can do cool stuff too.
3. Hair
Humans used to have tons of hair all over our bodies. Then, for some reason we decided to move south and lost it all because you don’t need fur when you live along the equator. A few millennia later, we decided that moving to the equator was a bad idea and moved north again…without our protective hair. Part of our wishy-washy legacy is the fact that while we don’t have hair anymore, we have hair muscles that reside just under our skin. These muscles are the cause of goose bumps. Now, not only do we get cold when the furnace shuts off, we also give off physiological signals when we are frightened. This alerts predators as to who needs to be eaten.

Ladies, please. One at a time!
4. Ears
A long time ago, our ancestors could swivel their ears around to direction where sound might be coming from. In this day and age, since we’ve evolved to have fixed ears, we don’t need to swivel because we can turn our heads. Even though about 10 percent of the population can still move their ears, it serves little purpose other than as a party trick. Further, a large portion of the population is born with what is called “Darwin’s point,” which is a vestigial ear feature that makes you look like a monkey.

A good example of doing it wrong.
5. Guts
A long time ago, before we stood on hide legs and walked around, our guts would hang down below our bodies, perfectly supported by our suspension bridge spine. Humans today go around with their guts being nestled in a cocoon of stomach muscles and are not supported as they should be. Because of this, every so often, a bit of our intestine can sneak through holes in that stomach muscle wall and cause a hernia. In men, it’s even worse because the testicles are also supported by those muscles and when the testicles descend during infancy, they actually come from cavities in that muscle wall. It’s like having a pre-built hernia just waiting to happen.
6. Brains
Yes, our brains are a marvel of evolution. Humans can split the atom and create Facebook and do millions of other notable and incredible things, but at what price? When our braincases decided to become larger they did so at the expense of our jaw bone. The gene that told us to get brains that could create fire and the wheel also told us that we didn’t need wisdom teeth anymore. It seems that thinking up modern dentistry was more important evolutionarily speaking than chewing on hard grains and fruit.

Yanking them out didn't make him any wiser.
7. Coccyx
Besides sounding funny, this vestigial tail is no longer needed by the human body except for the very important task of being the anchor point for the anus. This is a case where an old outdated body part was reassigned a new task. But what a shitty job.

The coccyx also makes a great place to put a really cool tramp stamp.
8. Throats
Our throats are set up completely wrong. In most animals, the throat is made so that there is literally no chance of something “going down the wrong hole” because the esophagus is located under the trachea. This is a case of evolution working in complete harmony with gravity. Since food falls down, it has no chance to become lodged in the upper tracheal tube. Now, in a case of evolution screwing with humans, we evolved a voice box that pushed the esophagus further down the throat, giving you a fifty-fifty chance of choking every time you put something in your mouth.

Another really famous "Choke"
9. Fat
Because our bodies evolved in a time when we didn’t know when we would be catching our next meal, we became very efficient when it came to storing our food energy in the form of fat. Unfortunately, we don’t live in that world anymore, so we tend to store calories we don’t need. Couple this with the fact that our tongues have evolved to seek out sweet, salty, and fatty foods and you get a case of the human body doing things that will eventually kill it.

The good news is now you can blame it on evolution.

I’m not even gonna touch this one.
