What biological purpose do goosebumps serve in humans?
Answer
They're a vestigial reflex from when ancestors had fur
Goosebumps are a vestigial reflex from our evolutionary past. When our ancestors had body hair, goosebumps would make hair stand on end to appear larger when threatened or cold. Humans retain this reflex even though it's no longer effective without fur.
💡 Did you know?
Goosebumps can be triggered by cold, fear, or emotional responses like hearing moving music—all handled by the same nervous system pathway.
