We must use clothing to keep out the cold. Why did humans evolve like this?

Human beings must rely on clothing to keep out the cold. This does not mean that humans have evolved like this, but that human beings are not like animals by nature. They will grow thick hair in the cold season and in the hot summer. These hairs will be shed when the time comes. People themselves do not have such characteristics.

Human ancestors did not have such characteristics. At that time, people found the furs of various animals for hunting to keep out the cold. The remaining furs could play a very good role in keeping out the cold. At that time, people The body hair of the human body may be thicker than now, but it is still not as good as the hair of animals. Even if it is thicker, it can at most withstand some slight winds. In winter, it cannot withstand it at all, so people first had This habit of living in a cave is because the cave can light a fire, keep warm, and keep out the wind.

Human beings themselves seem to be incompatible with the earth's environment, because human beings are not physically strong enough to survive in nature without the help of any modern tools. But now People are like this. Even people a million years ago had a very high mortality rate when their living standards were underdeveloped. According to the functions of the human body, if we are not contaminated and damaged by foreign objects, we can live to be 120 years old. There is absolutely no problem with left and right, but before the development of medical treatment, the average life span of a person was 30 to 40 years old, and many children even died because the virus infected them.

Because of this, some conspiracy theorists have come forward and said that humans themselves are not the original inhabitants of the earth, because humans have to use various devices to adapt to the earth’s environment, just because humans themselves are not like this. It was born out of an environment. It just means that we came to such a place through relocation, and then we used vaccines, clothing, and various tools to strengthen ourselves. Of course, this is just a conjecture. No one can tell whether it is true or not. Not sure.
