We humans have lived on the earth for about two million years, and the origin of our humans is four million years ago, when humans were still apes.
In the past three million years, due to adaptation to changes in the environment, apes have gradually evolved into humans, and in the process of human evolution, humans have gradually lost their hair and become more and more "smooth".
But in the millions of years of "slippery", we human beings have not worn clothes, and it was not until more than 400,000 years ago that human beings began to put on clothes little by little, and in those more than a million years, why have human beings not worn clothes?
And why should we face the fact that humans are wearing clothes like this?
What is the connection between human hair removal and dressing?
1. The third type of orangutan.
The origin of humans is that of great apes, and the original great apes were similar to chimpanzees and bonobos, both of which belonged to the primate gorilla family.
Moreover, the DNA of the apes at that time was very similar to that of chimpanzees, and they could even fertilize each other, so it can be said that there was not much difference between them.
However, as the apes evolved, their characteristics gradually emerged, eventually diverging from the chimpanzees into humans, and the DNA of the apes became more and more different.
Counting the fact that humans have evolved for four million years, and four million years ago, the DNA of apes and chimpanzees was very similar, but after four million years, the DNA of humans and chimpanzees has been one percent apart, and there are great differences in intelligence, stature, body shape, etc.
Taxonomically, chimpanzees and bonobos are referred to by scientists as "gorillas" and "orangutans".
That's why humans are called the "third type of orangutan" by scientists.
The differentiation between humans and orangutans is mainly due to the difference in living habits between them.
Orangutans live in tropical rainforests, and this humid environment and high temperature climate make the orangutans covered with thick hair, which not only provides good shade from the sun, but also protects them from parasite bites.
Human beings live in the savannah of Africa, and living in such a dry environment makes human hair gradually decrease and body hair gradually fades.
Just like the reason why the ancestors of humans "raised hair", the ancestors of orangutans and orangutans did not "raise hair", they also had times when they shed their hair.
Moreover, human body hair can be composed of keratin scales on the surface of the body, which are easy to fall off in a dry environment, which can effectively prevent the invasion of germs and parasites, or bites, which is beneficial to human health.
In human body hair, it is easy to hide parasites, which is the same as the habits of orangutans, which is also a reference for studying the origin of humans.
For example, humans living in the savannah in Africa have lice that grow in their hair, while humans in Europe have chest hair, which is also determined by the environment in which they live.
Their lice also live on their chest hair.
Humans in the Middle East, on the other hand, have pubic hair, and lice on pubic hair also grow on pubic hair.
In these contrasts, human beings are also constantly evolving with the environment, and it is also related to the climate, geographical location and other factors at that time.
Second, the origin of wearing clothes is possible.
So why do humans wear clothes after more than a million years of nakedness?
In the process of human hair loss, it may be due to changes in the environment, the climate becomes drier, so that the rate of human hair removal will also increase.
It may be that in the process of human evolution, the loss of human hair is related to the climate, geographical environment and other factors at that time.
Human beings gradually lose their hair, which can better dissipate heat and adapt to the environment, and in the process of hunting down prey, not only human beings have to pay physical strength, but even hair also has to pay a certain amount of energy.
In order to be able to hunt down prey more effectively, humans will appropriately reduce their body hair, which can not only save physical strength, but also catch up with prey faster.
Moreover, after the human body hair is greatly reduced, it can also better play the role of sweat glands, which can effectively cool down, so that humans can better adapt to the environment.
At the same time, it can also better prevent the invasion of germs and parasites.
Human hair removal is also to better adapt to the environment, adapt to the changes in the environment, and also allow humans to have more time to study other things.
Human beings wear clothes, more than 400,000 years ago, human ancestors put on animal skins, which is also to keep out the cold, and at the same time to protect from the wind and rain, and improve the quality of human life.
About two million years ago, the origin of humans was apes, and the body hair of apes was still very dense at that time, mainly because apes still had to adapt to the environment at that time.
At that time, great apes lived in the savannahs of Africa, where the environment was very dry, so that human body hair gradually faded.
The climate was very hot, so the apes' skin would be red, and they would get sunburned from the intense sun.
This will affect the survival of the apes, and if the apes are in such an environment for a long time, it will pose a threat to the survival of the apes, so at that time, the apes would use leaves, branches, etc. to shade the sun.
With the passage of time, human beings have slowly evolved into human beings like today, so that they have their own minds, so that they can share a certain amount of physical strength and adapt to the living environment.
On the other hand, about a million years ago, our ancestors began to disperse to all corners of the world, gradually adapting to different climatic environments.
Over the course of a million years, human body hair has become less and less, and gradually disappears in the course of human life, but human beings have never been clothed.
3. The relationship between hair removal and dressing.
Humans lost their hair but did not wear clothes, which was mainly related to the climate and environment at that time.
At that time, the climate and environment were very suitable for human survival, not only very humid, but also rich in animal and plant resources, which made it impossible for humans to wear clothes.
But about 400,000 years ago, there was a great ice age, and all of a sudden, the whole earth was frozen, and in the ice age, the temperature was very low, so at this time, human beings began to wear clothes.
Human beings began to wear animal skins to protect themselves from the cold, which was also the first gift brought to mankind by the "Great Ice Age", and it was also the luck of human beings.
In such a cold place, humans can survive.
Later, humans gradually began to raise domestic animals, so that there was a source of meat and milk, but the source of animal skins gradually decreased, so that in the process of human existence, it gradually disappeared.
This has led to human beings beginning to use hemp, cotton and other plant fibers to weave cloth, which can not only better protect against the cold, but also is very convenient to use and can be carried around.
Human beings began to have civilization, and they also began to have a rhythm of life, and at the same time, they could create and invent better tools.
Since then, human beings have gradually separated from animal skins, and began the naked life of human beings, which is also the beginning of human civilization.
epilogue
The process of human hair removal and dressing is not only a sign of human evolution, but also of the development of civilization.
In the process of constantly adapting to the environment, human beings are also constantly innovating.
So human beings have the ability to adapt to the environment and innovate.
