These observations are all consistent with the hypothesis that beards evolved to enhance fighting performance by providing protection to vulnerable aspects of the face.
The beard provides the face with protection from the elements, and a natural shield from the more delicate parts of the face around the mouth and lips. Next, prehistoric men grew their beards for protection. The thick, rich beards that they could grow were so full that they helped cushion blows to the face.
Physically speaking, men grow beards because the hair follicles on their faces are stimulated by a derivative of testosterone: dihydrotestosterone (DHT). Despite a reputation that lags behind the original hormone, testosterone, DHT is extremely potent and influences bodily functions in several ways.
It is mostly for sexual selection. It is taken as a sign of maturity and strength by females and became more common among males as the bearded ones were more likely to reproduce. Also, according to a study published in Organismal Biology, beards can help soften blows to the face but that's likely not the main purpose.
“The benefit of having a beard is protection, as well as esthetics,” Dr. Harvey says. “Its good protection against wind, chafing and traumatic injury. It's also a trend, so we see a lot of men with some form of facial hair.”
Religions such as Orthodox Judaism, Rastafarianism, and Sikhism all prohibit haircuts, the removal of facial hair, or a combination of the two due to beliefs that hair is sacred or a gift from God.
Additionally, facial hair has been shown to positively impact mating success in highly competitive environments (Barber 2001; Dixson et al. 2017). These observations are all consistent with the hypothesis that beards evolved to enhance fighting performance by providing protection to vulnerable aspects of the face.
There is no specific ethnicity that can't grow facial hair, but East Asian individuals, such as Japanese and Chinese, tend to have less facial hair and slower growth rates compared to other ethnicities.
Pubic hair serves several purposes. These include disease prevention, maintaining optimal genital temperature, and friction reduction.
Your genes determine how sensitive your hair follicles are to testosterone. If your follicles are more sensitive to this hormone, then you'll have more beard growth. Scientists have found dozens of genes that play a role in facial hair growth, like the gene LNX1 on the human chromosome 4.
One theory put foward by researchers Muscarella and Cunningham susgests baldness may have evolved in males through sexual selection as an indicator of aging and social maturity when males become less aggressive and more nurturing.
If you have not met any Native Americans yourself, you may have a stereotype that Native Americans do not have facial hair—only because that is what most of the photos online (and movies) want you to believe. However, Native Americans with beards do exist.
The connection between manhood and unmown cheeks today has flowed down through church history, like oil running down the beard of Aaron (Psalm 133:2). Augustine, commenting on Psalm 133, writes, “The beard signifies the courageous; the beard distinguishes the grown men, the earnest, the active, the vigorous.
It's effective against bacteria including Streptococcus, Staphylococcus and tuberculosis. It was traditionally used to treat wounds; Native Americans used it as a compress to prevent infection and gangrene. It is also said to be edible and contains a high level of vitamin C.
In ages past, shaving was thought to give a tactical advantage in battle. During the Roman empire, the legions of discipline Phalanx and foot soldiers were often told to clean shave before the eve of battle. It was believed that having a long beard could be a potential weak spot.
Anthropologist Joseph Deniker said in 1901 that the very hirsute peoples are the Ainus, Uyghurs, Iranians, Australian aborigines (Arnhem Land being less hairy), Toda, Dravidians and Melanesians, while the most glabrous peoples are the Indigenous Americans, San, and East Asians, who include Chinese, Koreans, Mongols, ...
Only old or distinguished men (who could afford to ignore fashion) wore beards, and these were at best thin and wispy. We should add that, in Esther Pasztory's words (Aztec Art, 1983, p.
Does No Beard Mean Low Testosterone? That's not entirely true. Testosterone can influence facial hair quality, but when your genes are not favorable for beard production, testosterone can't help. Most men have similar levels of testosterone, including men without a beard.
Correlated research to this study pointed towards the fact that beards most likely evolved in men to help men boost their interaction among and over other men. More dominant men are most likely to get further mating opportunities when they intimidate their rivals and put them aside.
Beard is a 24/7 Sunnah you are carrying with yourself. By keeping beard you look different from disbelievers, this has been emphasized in various Hadiths of the Holy Prophet Muhammad (PBUH) for instance said, “Cut your moustaches and leave your beards. Be different from the people of scripture,” (Muslim).
In Viking society, beards were more than just a fashion statement. They symbolized the transition from boy to man and were a sign of wisdom and experience. Warriors with long, well-groomed beards were often seen as particularly brave and honorable.
Leviticus (19:27): "You shall not cut the hair on the sides of your heads, neither shall you clip off the edge of your beard." To cut off another man's beard, according to Samuel (10:4) is an outrage. According to Jeremiah (41:5), to shave or pluck one's own beard was only appropriate during times of mourning.
Throughout the Middle Ages, priests were marked by their beardlessness and tonsure (a shaved top of the head). Long beards became a sign of a "multitude of sins,"; although many clerics copied nobles who frequently sported beards.
The majority of Muslim scholars consider that it is forbidden (haram) to shave the beard as it would be neglecting the tradition and established practice of the Prophet Muhammad (peace be upon him) who encouraged followers to strive to imitate him in every way.
