You would think that as a species we would have evolved to a point where we understand why these things do or don't happen. But they're still a mystery to us.

Goosebumps are the result of flexing muscles at the base of each hair follicle. There are two reasons humans get goosebumps. The first happens when someone is cold. The second is when you're scared and works much like a cat's fur when it feel threatened - By raising the hair when we’re ready to fight it made us appear bigger. Okay, it would, if we had fur.

Humans are the only species on Earth that has exposed lips. No animal shows interior skin on their mouth like we do.

At some point in our ancestral history, our ears moved directionally. Like a horse’s, we could move them around to be able to hear things better. While that ability is mostly gone, we all still have the auriculares muscle which surrounds the outer ear.

Although wisdom teeth are now simply painful and frail, they once served a very important purpose. A long, long time ago, pre-humans were primarily herbivores, which meant they ate a lot of greens. Because green vegetation takes longer to digest, it needed to be chewed more, and wisdom teeth gave the extra surface area needed to grind the greens into pulp.

Although the appendix does seem to produce some good gut germs to help the digestive system, we don’t really need it and those that have it removed suffer no real consequences. It seems it is simply left over from a previous version of us.

No animal on Earth had breasts like a human does. It seems like they evolved after we started walking upright. They began to become rounder and bigger until they've started to look like the boobs of Today.

#6 - Yay, evolution! I once read that they may have evolved to resemble shapely buttocks so that we males would be attracted to mates who weren't walking on all fours, exposing only the buttocks. There was a similar theory about why lips are exposed and why they are a different shade from the rest of our facial skin. It's all about communication.

Goosebumps raise our hair to capture more air. By doing so they make a thin layer of isolation to keep the body warm.
