Ok, these are technically not a body part, but a human’s goosebumps still serve little purpose. No one has ever gotten a little chilly and thought to themselves, “Wow, I’m glad I have goosebumps right now; I feel so much better.” That’s because they’re remnants of a time when humans had thicker hair. When mammals get cold, the muscles around their hair follicles contract, making the hair stand on end. For our furrier friends, this creates insulation, their thick hair retaining body heat to warm the skin. Goosebumps can also appear when frightened, the puffed up hair making the animal look bigger and more intimidating. But in case you haven’t noticed, humans don’t have fur anymore, meaning goosebumps are now nearly useless.
