Why Do We Have Beards? While Beards Are Completely Biologically Useless
Have you ever wondered why we have beards? In fact, scientists have shown that beards are not a biological trait of the body the way we thought for many years. Beard is like an ornamental plant.
Out of all the biological features of the human body, including other types of hair, only beard has no function and has only decorative meaning. That means it doesn’t actually function or perform any specific physiological effects. Let’s take a look at the remaining hairs on our body.
Body hair helps to regulate temperature. The hair on the head helps to protect the scalp from the sun and helps keep it warm in cold weather. Eyelashes help protect your eyes from insects or strange objects that can come in when you open them. The eyebrows help prevent sweat from flowing into the eyes. Armpit hair helps reduce friction when moving hands and keeps sweat from escaping. Genital hairs help protect against bacteria and also help reduce friction.
But beards do not have any specific effect. So why do they exist, and why only exist in men?
In the early days of beard research, evolutionary biologists thought that beards could have the same effects as hair or hair on the genitals. It is to keep body temperature and avoid bacteria coming into mouth contact. It sounds reasonable, but when it comes to another aspect, these inferences must be discarded.
That is 50% of the population worldwide, women with absolutely no beards. There are also differences between males and females in the wild, but rarely an important trait appears only in males, whereas females responsible for breeding, and they do not have that feature.
If the beard has an important role in the human body, it should be in both sexes. Instead, beards or mustaches appear only in men, in adulthood and until old age. They are simply there doing nothing, and they keep growing no matter how many times we shave.
Beard can help attract sex partners?
