9 Body Parts Humans Don’t Really Need

Our bodies are weird! They sometimes smell bad, make strange sounds, and have some of the most useless features ever. If you really think about it, our body has not been optimized or updated by evolution in thousands of years, which means that we look and function almost exactly the same as our ancestors 30,000 years ago. Maybe back then we needed those appendixes and ear muscles to survive but today we have a lot of useless baggage, so to speak.

Here are 9 body parts humans don’t really need.

1. Arrector Pili (smooth muscle)
These little musclaes make our hair stand and give us goose bumps, which gives us zero evolutionary advantage. Well, maybe aside from being able to tell if a song is good or not.

2. Body Hair
Even hair itself is a relic of the past. Everyone wants to get rid of it anyway, so why do we need it? (the answer is: we don’t)

3. Auricular Muscles
It would be cool if we could swivel our ears like cats and dogs, but alas, best we can to is slightly wiggle them with the auricular muscles.
