The famous biologist Charles Darwin put forward the famous idea of "natural selection, survival of the fittest" in the process of evolution, but when facing the beard on a man's chest, Darwin did not understand who this "fittest" was.
So how did the beard come about, how did it form on a man's face from an accident, and what is the important relationship between this beard and the development of human society?
1. The evolution of the beard.
The beard is both a facial hair and a symbol of culture or tradition.
Beards have different meanings in different cultures, from the beard god of ancient Egypt to today's American-style beards, beards carry different meanings.
In ancient Egyptian culture, the beard was considered a sacred symbol, and the beard was even shaped into a kind of god, the beard god of ancient Egypt was a woman who had both a woman's chest and a big beard, and the meaning of the beard god was to bring fertility to men, but also to bring fertility to all things in heaven and earth.
The ancient Egyptians even regarded the beard as a sacred symbol, and they would carve the shape of the beard according to various animals, thus invoking the strength of various animals so that they could be strengthened and protected.
In ancient China, the beard was given a different meaning, and the beard was seen as a symbol of longevity, and the beard was often used for styling to bring luck to men.
In the Hindu sects, the beard is also considered to be a symbol that can bring wisdom and strength, and the bearded god in the Hindu sect is a man with a particularly long beard, which will bring wisdom and strength to the believers in the sect.
In Islam, the beard is also regarded as a doctrine, and the beard in Islam refers to a person who has a particularly long beard, and the believers in Islam will keep the beard very long so that they can maintain a halal state.
In modern America, the beard has been given a different meaning, the beard is a sign of men in the United States, and the beard is often used to decorate it, thus bringing strength and luck to men.
In the United States, the beard is also a symbol of social hierarchy, and the longer a man's beard is, the higher his social status and the higher the degree of respect.
The beard is also a symbol of a man's status, American men generally keep their beards very long, so that they can reflect the temperament of men, and women generally keep their beards very short, or even shave off their beards.
The cultural significance of the beard is also found in various ethnic cultures, including Xinjiang and Tibet, where people grow their beards especially long, and people generally use them for decoration to bring themselves luck.
Xinjiang people keep their beards especially long because they believe that they can give themselves the power to give birth, so that they can give birth to more offspring, and the beard is also a symbol of honor, the longer the man's beard, the higher his social status, the higher the degree of respect.
Tibetans keep their beards especially long because they believe that they can bring wisdom and strength to themselves so that they can survive in difficult environments, and the beard is also a status symbol, and the longer the beard of a man, the higher his social status and the higher the degree of respect.
Second, the formation of a beard.
Beards are formed because men have more hair follicles on their faces, and these hair follicles will constantly produce new hairs, so that the beard will continue to grow outward, and the growth of the beard will be affected by many environments, the largest of which is male hormones.
Men contain more male hormones, this male hormone will promote the gradual maturity of a man's body, including the growth of beards, men's beards will continue to grow with age, and generally boys' beards will not grow, because they do not have much male hormones in their bodies, and they will not have too many beard hair follicles.
Men's hair follicles are constantly producing new hairs as they age, which makes the beard grow continuously, but this rate of growth is not constant because it is controlled by male hormones.
Male hormones are hormones secreted by the hypothalamus in the brain, and this hormone increases with age until a man's body contains more hormones, which causes the growth rate of beards to increase continuously.
But this increase in growth rate is not static, it is affected by many factors, the most important of which is the brain, which regulates the hormones in the body so that the hormones in the body are maintained at a stable level.
As the brain grows older, the function of the brain will continue to increase, which makes the brain's control of hormones more flexible, that is, the brain can regulate hormones at any time.
The regulation of hormones in the brain is also affected by the mood and environment of the man, the better the mood of the general man, the faster the growth rate of the beard, but when the mood of the man is bad, the growth rate of the beard will become very slow.
A man's beard is also affected by genetics, generally a man's father has a long beard, his beard will grow well, but if his father has a bad beard, his beard will not grow well.
A man's beard is also affected by his diet and lifestyle habits, generally a man will grow well if he eats well, but if his diet is too poor, the beard will not grow well.
A man's beard is also affected by the nutrients in the body, generally the more nutrients a man has, the better the beard will grow, but if he has too little nutrients in the body, the beard will not grow well.
3. The meaning of the beard.
The beard used to be a very important organ in the evolution of humans, the beard was able to protect the man's face from the outside world, and the man could use the beard to combine the skin of the face with the hair follicles of the beard, thus forming a hard protective layer.
This protective layer is able to protect not only the face from external aggression, but also the man's body from external aggression, which plays an important role in the man's survival in the harsh environment.
However, with the development of human society, the beard gradually lost its importance of protection, and men began to use the beard for decoration to bring themselves luck.
In early human society, men would use their beards for decoration, and the longer the beard of a man, the more courageous, powerful, and respected he was.
Therefore, men will use the beard for decoration, and generally men's beards will be very long, even to the neck, and men will also use the beard for styling, so as to bring luck to themselves.
Beards are also often used for religious purposes, and some religions have grown their beards especially long so that they can follow their teachings, and beards have a rich cultural meaning that is worth exploring.
epilogue
The beard is a very interesting organ, it can be not only a cultural symbol of people, but also a reflection of people's physiological characteristics, and the evolution of the beard may be the result of the interaction of many factors, which reflect biodiversity.
The cultural symbol of the beard has a rich and diverse meaning in different regions, which reflects the diversity of human society, and we can learn more about the mysteries of evolution by studying the mechanism of beard growth.
