To modern humans, goosebumps probably don’t seem very useful. But long ago, they were practical for your ancestors.

Early humans used to work in harsh climate conditions. Homo sapiens were once covered in lots of fur.

Goosebumps provided early humans with some extra protection from the cold, functioning a bit like built-in puffer jackets.

Hair-raising goosebumps were also a response to threats, which would have made them appear larger and scarier and provided protection against enemies.
