Did monobrows bring any advantages for humans in ancient times or are they just randomly there?
In: Biology
A monobrow, where eyebrow hair meets across the bridge of the nose, doesn’t have a specific advantage; it’s more about genetic variation in appearance, like hair color or height. Eyebrows in general help protect our eyes from sweat and rain, which was useful for ancient humans. The monobrow is just one of the many looks that come from our genetics, not a trait evolved for a specific benefit.
