Almost all animals, including those close to us, have fur. So why are we not like that?
There is a new creature that comes to earth and puts us together with other animals—one of the first things that separates us from the zap of standing on two legs and the special way of wading.
Normally, compared to other animals, humans generally have no fur (in which case some are also rarely found). There are very few animals that share this human domain, including hippos, elephants, rhinoceros, furless whales, whales, and very few others.
So how did it go well and well to find ourselves looking just where we are? Does it have any benefits at the moment? And how do you explain how much hair is on some parts of the body?
Yes, people have a lot of fur: on average, we have five million fur buds on our body. But almost all of these tubes contain small, very soft, very small, very short tubes, which allow these tubes not to reach far in the body. These furs differ from the long fur that grows on some parts, such as hair on the head and hair, the side fur of the genital area, and the beard in almost all men (behind the age of adolescence).
The most important is the “control of body moisture, known as the hypothèse de la “savane”/”savannah” hypothesis. This theory suggests that it was necessary for early humans that their bodies had the ability to control moisture, which caused them to lose their fur.
During the period known as the Pleistocene, the Homo erectus, later known as hominids/hominins, began to hunt heavily in the wild, running on animals for hours to hide them without using the advanced hunting equipment that was later found in the equipment of the place before.
These hidden activities have caused problems with excessive humidity; the result of the loss of fur may have enabled them to boil more and throw away moisture and water without even resting.
This is also based on research showing the evolution of certain genetic factors that cause certain cells to form hairy or hairy tissues.
“So all these things are involved in physical evolution,” Lasisi said. Looking at all this and joining it with other things we have been able to vote on about the natural areas that have increased the evolution of the color of human skin, we can confirm without doubt that from two million to one million years ago… people may have lost fur on their body.”.
Meanwhile, Lasisi says that hyperthermia may have been a bigger problem than hyperthermia in Africa’s equatorial Africa, where humanity has begun. “For me, it seems that there is a struggle against excess humidity, superior to having moderate humidity.”.
He also says that many natural areas can change so that it is difficult to return to the way we were in the past. Finally, he added that by the time people arrived in areas of extreme cold, they had already picked up other warming techniques, such as fire and dung. They are also similar to those who have chosen other techniques for cold body training, such as the oil that controls body moisture (brown fat adaptation).
In 2003, Pagel and his colleague Walter Bodmer at Oxford University gave another lecture on the cause of the first loss of fur, a parasite-based hypothesis, which they called the hypothèse de l’ectoparasite/ectoparasite hypothesis. They explain that a hairless monkey is not affected by insects, which is a special advantage for it.
“Looking around the world, mosquitoes are still a serious problem, as examples of flies that cause disease,” Pagel said. These flies have a unique ability to live and live in fur and lay eggs in wool. Thus, ants may have been one of the factors that caused the transformation of humanity, and they are still like that.”.
Pagel says that “nothing comes to contradict this idea since he and Bodmer first showed it.
Lasisi says he can’t put aside the factors involved in the loss of wool. According to him, “you have to wonder why this happens to people but not to monkeys.”.
I look like a superior caregiver who can show behavior or immigration that has separated people from monkeys so that it would require a loss of fur.
