Why do all the creatures on Earth only humans need to wear clothes to keep warm?

Because the body hair of humans disappeared during the evolutionary process, the body could not resist the cold, and other creatures did not need clothes to resist the cold, so the creatures on earth only humans needed to wear clothes to keep warm.

According to the theory of evolution, only humans make clothes, so human body hair degenerates, while animal body hair does not degenerate, so they can keep warm.

1. Human beings are not like other animals, other animals have thick hair, which can play a good role in keeping out the cold in winter;

2. Humans are homeothermic animals, and they have no fur to resist the cold, so they can only keep warm by wearing clothes;

3. Human beings are still high-level animals and have a sense of shame, so they have to wear clothes.

Because other creatures have evolved the most suitable fur according to the climate of their habitat, and human beings have been active all over the world, and human body hair is only a thin layer, and the limbs and dates need to be kept warm by clothing.

Because human ** is particularly thin, human beings have no fur protection, so this is the case.

Because humans have evolved enough, while other creatures have not, and animals have a fur on their bodies to keep warm, but humans don't, so they have to rely on enough clothing to keep them warm.

I think that in order to better integrate into the many heat released from the excessive exercise of walking upright, the hair slowly fades in the course of development, therefore, in the case of severe cold, it is necessary to wear clothes to keep warm, and secondly, some people think that when the early Homo sapiens evolved around the hot equator in Nahon Africa and moved to other parts of the world, in order to better integrate into the colder climate of other regions, they had to wear clothes to keep warm, to understand why humans wear clothes, the first thing to deal with is when humans gradually wear clothes.

As everyone knows, it is difficult to determine the exact time when human beings gradually wear clothes, the early clothes are like animal skins, will decline rapidly, therefore, there is basically no archaeological direct evidence that can be used to determine the date of human clothes gradually worn, and according to the scientific research of the evolution of color genes, about 100 million years, human beings lost their body hair, which is actually the idealized time to gradually wear clothes to keep warm, as everyone knows, the first special tools for scraping animal skins found so far can be traced back to 780,000 years ago.

Animal skins are also used for other purposes, such as giving shelter rather than making clothes, and the eye needles used for clothes gradually occurred about 40,000 years ago, but this special tool is used for more complicated clothes, which means that clothes have been around for a while, and we can see from the migration maps of humans that the fading of body hair is likely to have an indispensable connection with the early human experience in Africa, after all, there are many advantages in hot regions where there is no long, dense body hair.

For example, some people who are not suitable for running are very easy to get caught in the trap when hunting or working, but we don't know that we humans don't have a genetically mutated body hair group like the long tongue of an animal like Leo to assist in heat discharge, but we don't know that in this link, long body hair can maintain the body from bush scratches in a relatively limited way, and then, although the advantages of removing body hair are significant, the possibility of injury increases significantly, and then slowly wearing animal fur to protect yourself becomes an inevitable choice.

The question of why only humans have to wear clothes to keep the microbes on Earth is here today.

Because humans do not have the ability to prevent wind and cold, humans need clothes to keep warm, and animals have soft fur.

This is because human beings are thinking creatures and also have the psychology of covering shame, so they need to wear clothes to keep warm.

Because other animals can use their hair to resist the cold, humans must use clothing to protect themselves from the cold and hide their shame, which is very beautiful.

Because human beings have gradually lost their hair in the process of evolution, they do not have any shelter on their bodies, and they feel very cold.

Because the human body has no fur on the outside, the fat is particularly thin, so it can only be kept warm by clothing.

The fact that only humans need to wear clothes to keep warm is due to the fact that many of the functions of humans have been degraded!

Unlike many animals, which have thick fur, humans have only a small amount of hair, so it is difficult to resist the attacks of low temperatures, and they do not sleep in winter. Therefore, in the face of the drop in temperature, especially in winter, when the temperature is more than ten degrees below zero or even dozens of degrees, if you have no clothes, you can only freeze to death. Therefore, this can also be seen as an effective measure for humans to adapt to the environment.

Even people in different places have different kinds of clothes to keep out the cold.

Of course, in addition to clothing to keep warm, humans not only have to build nests like animals, but also build heating or air conditioning facilities. Only such comprehensive measures can make the hail so that human beings can withstand the low temperature. This also shows that there is a huge gap between humans and animals in this regard.

It is also a full manifestation of the weakness of human beings themselves.

Humans are much weaker than animals, so they must use clothing and heating equipment to resist low temperatures!

Because other creatures have hair, and their hair is very dense and thick, which is equivalent to human clothes.

Mainly because other organisms grow fur, and their fur can serve as a source of warmth.

Only human beings on the earth need to dress and keep warm, and the direct cause is the degradation of human body hair, which seems to be a very simple logic, but in fact, the logic behind it is not simple. Before the degeneration of body hair, human beings, like apes, did not need to be clothed all year round, but why humans gradually lost this physiological sign has to start from the process of human erection and the African continent.

First of all, when humans first began to wear clothes, they did not come up to keep warm, but to protect the body, because in the process of evolution, in order to adapt to the cruel jungle life, human beings gradually changed from walking on all fours to standing, but this process also exposed the weak organs of human beings in front of the body.

In order to avoid being injured in the hunting process, human beings gradually used leaves, animal skins and other materials to make the simplest clothes, after all, human beings in the process of evolution, in addition to standing, the more advanced evolution is to have wisdom, and later in the process of practice, human beings found that clothes can not only be used to protect the body, but also to keep warm, so the clothes are getting bigger and bigger, the covering parts are more and more comprehensive, and finally the body hair degenerates.

Some scientists have found that about 1.7 million years ago, human hair had not completely degenerated (Homo erectus), and by 250,000 years ago, human hair began to become thin. Because human ancestors first began to be active on the African continent, and the temperature on the African continent is relatively high, the ancestors' need for clothing and warmth is not so strong.

However, during the period of Homo sapiens, human beings gradually began to migrate to Europe and Asia, and the temperature in these areas was relatively low, so the clothes worn by humans became thicker and thicker, and the hair began to become useless.

However, there is a misunderstanding to be corrected here, many people do not understand, obviously belong to modern human beings, why Europeans and Americans generally have more body hair than Asians, is it because of more body hair, so Europeans and Americans are more frost-resistant, in fact, no, no matter how much body hair Europeans and Americans have, it also belongs to the category of sweat hair, which has a world of difference from animal fur.

The reason why there is more body hair has a lot to do with their daily eating habits, Asians basically eat fine grains, while Europeans and Americans eat more meat, what medium-rare, six-cooked steak does not refuse, in the long run, we have hair genetic differences, which is like the genetic differences between China's multi-ethnic groups, some people are goatees, and some people are more bearded.

Finally, there is another reason why humans need to wear clothes to keep warm, that is, activities regardless of the four seasons, although humans are different from other hairy animals, but physiologically humans still belong to the category of mammals, and mammals basically belong to the "homeothermic animals", relying on their own temperature regulation, can survive the cold winter.

However, human hair has degenerated, and it is impossible to expose ** to cold air in winter, but it is not like "cold-blooded animals", which hibernate in winter, so the measure to support human winter activities can only be to wear clothes, so that clothes have become an indispensable living item for human beings.

It is because in the process of human development, the fur of the body has all retreated, and there is nothing to protect the body temperature, so it is necessary to wear clothes to keep warm.

Because in the process of human evolution, the fur has been withdrawn, but other animals, they either have fur or scales.
