In the beginning, human beings used the tools of life and labor. They were very simple, and even in terms of clothing, they were made from natural materials. Only after years of development, and through the creation of civilized science, our biological instincts technology has made good progress.

In fact, our animal nature still exists, for example, we and mammals remain always similar. There is a very obvious point of difference between humans and animals, that is, animals have a fur, humans are basically no obvious long hair. It is because of this phenomenon, so everyone is wondering whether the human is changed by the original? Why is full of hair are faded?

It is after continuous research by scientists to develop the time of human hair removal, the point should be after the last common formation of humans and orangutans, of course chimpanzees are considered our close relatives, humans are after the analysis by pigmentation, indicating that slowly hair has begun to be absent. But this process takes not very short time, a total of at least millions of years.

There is also a part of the argument is actually due to the evolution of the human species in the process of evolution may be through the fossils of animals to change, of course, hair this material in the animal will soon decay away after death, is no way to form fossils, of course, this is also for human hair evolution of a statement, but this statement has been very challenging, may also be some suspicion. So far, about hair is also not enough evidence to solve, of course, is also in the research all the time, that is to say, our knowledge itself is infinite, but in the future people may be completely when this mystery solved. Look forward to it together.
