Beard is a masculine symbol associated with men. However, have you ever wondered why men have beards while women and children do not? What is the purpose of the beard?

Humans are almost the only hairless mammals to cover their bodies. So we invented clothes that do the duty of keeping warm. But what about beards? Why do we have beards? And why only men have beards and women and children absolutely do not have?

Previous studies have explained this, suggesting that men grow beards to attract females and increase their ability to find mates. However, a recent study has shown that the main purpose of growing a beard is just to become more confident and masculine in the face of other men.

And not only beard, voice is also an evolutionary trait for this. To prove it, scientists in the UK conducted a study of 20 men and 20 women. Applicants will be asked to rate the masculinity and sexiness of the 6 men.

The results showed that men with deep, warm voices were considered to be seductive. However, the problem is that the right voice is “just right”, and the high and low tone must be taken lightly. On the contrary, the deeper the voice, the more intimidating he becomes to other men. As for beards, even this factor does not affect the level of sex appeal. However, a person who has no beard when growing a beard will become more prestigious.

In fact, there have been some previous studies suggesting that women like bearded men, but all are not enough evidence. What’s more, many studies have shown that many women find men to have a smooth beard to look good.

Therefore, scientists have come up with another possibility. Specifically, in the issue of reproduction, we are not simply beautiful but also have to compete with individuals of the same gender. And this is exactly why men need to grow beards.
