    Doesn’t evolution highlight thst the hair being there means it WAS/IS useful or wanted? I’m pretty sure those hairs act as a germ net or something, or maybe it’s just because that part of the body is best kept warm.

      No, evolution allows for vestigial parts all the time. And sometimes random mutations happen and doesn’t make much of a difference so it doesn’t get selected out and now there’s just something there for no reason that never had a purpose.

      I’m pretty sure those hairs act as a germ net or something, or maybe it’s just because that part of the body is best kept warm.

      The biggest argument against that is the fact that humans have lost most of their body hair anyway and still managed to thrive. Not that it makes leg hair bad, but we clearly don’t need it to survive.
