Why do humans have eyebrows?

Eyebrows in addition to beauty effects, it also helps us more than you think.

It can be said that the face is one of the most miraculous things that nature has bestowed on humanity. Except for the twins, each person has a different beauty, a different appearance, no one resembles anyone. And often to become attracted to the eyes of people, we often pay more attention to our faces. They can wear make-up, change hair style, men can beard or not . All affect your face, sometimes become different, can be more attractive. There is actually one thing that people often forget, especially men, that eyebrows always play an important role in your appearance. Some people do not like to hair, others do not like to beard, but everyone wants to eyebrow. Why is that?

What happens if this important character doesn't have an eyebrow?

Eyebrows in addition to beauty effects, it also helps us more than you think. The most typical is the ability of the eyebrow to express great. You can move your eyebrows up or down or contract to express your thoughts, sometimes this action takes place as an unconditional reflex. And we all know that the different positions of the eyebrows express a different nuance of the face.

The eyebrows help us beautify, help us communicate, but let's go back to human evolution: Why did we lose most of the thick hair on our bodies but still retain a little in above my eyes? Scientists are not entirely sure why modern humans still retain them but they can also conclude some assumptions.

We all know that eyebrows help keep sweat from flowing directly into the eyes when we work a lot or go in the rain. The arch shape of the eyebrows helps divert sweat around the face, keeping the eye dry. This is especially important for humanity to navigate and continue to move. Eyebrows help prehistoric people move in the rain or when sweating, and obviously it brings a great advantage. Besides, there is salt in the sweat, so the eye can be sore if sweat is flowing directly into it.

What can replace our eyebrows?

During evolution, eyebrows play an important role in human survival. Clear sighting in the rain makes it easy for them to find shelter, even to find their way home on long trips. Or when they want to hunt a predator, they have to move a lot. Sweat will be released and without eyebrows, they will not be able to see the way to catch them. In case of being chased, we can easily escape faster. Because of such great advantages that nature has chosen to retain eyebrows for modern humans today.

Most scientists believe that if not the eyebrows, surely humans will evolve something else to replace them. For example, humans can develop a thick layer of eyelashes that shield the eyes from sweat or rainwater. Or maybe our skull will continue to protrude to form a ledge right above the eye. Therefore, rainwater will flow to the face without falling into the eyes, making it easier for us to move.
