All mammals are all very hairy with no exception to human. But compared to our close relative chimpanzees and gorillas, humans are practically bald. The visible hair we have is primarily for our scalp, and once we go through puberty, our thighs and armpits.Our sparse nature is baffling, but there is a thorny question lurking beneath our eyes: Why do men, and not women, often have so much hair on their faces, especially the beard and jawline area?
When we look into why beards are reserved throughout evolution, sexual attraction may come into play. Beards are not unique even to humans. "Exaggeration of facial hair is not uncommon in mammals (lions are notorious for having masculine beard looking hair), and many primates have facial hair trappings, such as graying facial hair.
“There are two selective pressure that shape the evolution of gender-dependent traits” like the beard, explains Brooks. "One is if it gives you a competing advantage over other members of the same sex in survival, and the other is that it makes you attractive to members of the opposite sex." which both facilitates the passing on of the traits through reproduction.
Beards can fall into both categories of the selective pressure, so they are probably not a random evolutionary accident: there is decades of research into the role they can play in the governance of human behaviour between men and women, and between men and other men.
So, is a beard still attractive to women who love men? In a recent survey targeting women aged 21-40, 73% of the respondents favors the same men with beard over them without the beard through pictures shown.
21% of men say they have a beard because nature has made it so. I can argue with that.
Mammals are tough. We should be tough animals. And there is no razor on earth that will stop our hair from growing. There are also people like that who have never shaved. All the time! As nature had predicted.
