Why aren t humans covered with hair like animals, is it because they wear clothes?

We humans are also mammals.

But we didn't have a full body of hair like other mammals, we just kept the hair in the important areas, and the rest of the place has already lost the hair. We lose our hair, I don't think it's because we wear clothes, it's just the result of not having hair, it's not the reason. So far, we have not found the real reason for the loss of human hair, and now there are only some hypotheses, among which the heat dissipation theory and the fire theory are more popular.

Removing the hair makes it easier for humans to hunt their prey. With the physique of a human being, and the absence of sharp claws, it is indeed very difficult to be a good hunter in nature. However, early humans did not give up eating meat, even if they were born with poor conditions, but in long-term practice, they also found their own advantages, and their endurance was particularly good.

Humans are good at running, and this may be nature's compensation for humans. In the beginning, humans were not smart, they did not set traps, they could only rely on physical strength, and kept chasing animals until they ran to death, and then they took the animal carcass back to eat. Since they run a lot, the hair on their bodies is not conducive to heat dissipation, so the hair on their bodies slowly fades.

After learning to use fire, hair caused a lot of inconvenience to humans。The use of fire has epoch-making significance for human beings, and after learning to use fire, human beings have become more distant from other animals. After humans learned about the use of fire, they began to cook food, so that their bodies were better, and their brains began to develop rapidly.

It's just that there is a disadvantage to using fire, the hair on the body is often burned, and sometimes the hair on the body will be ignited, which is very unsafe. Then, in the process of evolution, the human body gradually gave up hair.

These are the two hypotheses about human hair loss, and I think they are quite plausible. Regardless of whether or not human hair loss is actually due to these reasons, hair loss is obviously very correct.

Yes. According to the theory of evolution, natural selection is the survival of the fittest.

No, because humans have evolved to selectively express their genes, they don't grow hair all over their bodies.

A certain factor is that humans have learned to use clothes for warmth, so that hair loses its meaning and gradually becomes tiny plush.

Man is a higher animal, and after hundreds of billions of years of evolution, he changed from an ape to the current human.

The presence of body hair is an atavistic phenomenon.

Still, I like men with chest hair.

Animal hair can protect against the cold, resist the invasion of bacteria, and protect the body, just like the clothes worn by humans and the quilt covered, which is very comfortable. In winter, it can resist the cold, and in summer, it can protect against ultraviolet rays.

At the same time, the hair of some animals can protect themselves from being eaten by natural predators, such as zebras, rabbits, black goats and other weaker animals that want to defend themselves against natural predators.

Some animal hair has a peculiarity, such as the camel's eyelashes are very long, and the purpose is to prevent sand. Cats have long whiskers, which act as a detector and so on.

In ancient times, the natural environment was harsh, and in order to adapt to life and the environment, various animals (including humans), adapted to the environment to survive (survival of the fittest). Now, after a long period of environmental transition, the ability to adapt has been strengthened, and social science and technology have developed. People can keep warm in other ways, so with the change of the environment, some organs of the human being have changed.

I can tell you very clearly.

That's because of natural evolution.

If you still don't understand, then you can start from scratch and evolve again!

Because in the process of human evolution, some organs that do not need to be used have been simplified!

Because human beings continue to evolve, there is no primitive wildness, and gradually evolves to the new human beings now.

If people really have that much hair, they don't need to wear clothes anymore.

Humans are not primitive creatures on Earth

Man has gradually degraded in the course of evolution.

Human hair also stops growing when it reaches a certain length, but we don't cut it off when it grows to that length, so we mistakenly think that hair will always grow.

Human hair.

In general, the growth period can be as long as 3 to 10 years, the degeneration period is 2 to 3 weeks, and the resting period is 3 to 4 months. Healthy young people have at least 85% of their hair in the anagen phase. The average hair is centimeters long a day.

It is not possible to be infinitely long. The hair of animals grows periodically, and most animals will lose their hair when climate changes. I don't know, kid, you're stupid!!

Why do animals have hair on their bodies, but people only have hair on their heads?

Hello, human beings have gradually lost their heavy hair in the process of evolution. Because less hair is better for heat dissipation, humans have more stamina than animals. Although humans do not have the speed of a cheetah or the dexterity of an antelope, their ability to travel long distances can exhaust the physical strength of their prey and capture them.

So you say you don't have stamina, you don't have sustainability? Is it lazy, or is it lazy? So why do people have hair on their heads, armpit hair under their armpits, and eyebrows on their eyes?

Hair is meant to protect the mind, protect from the scorching sun in summer, and the cold in winter, and prevent lighter collisions. Armpit hair is used to prevent friction when the upper limbs are moving. The eyebrows are to prevent rain from reaching the eyes.

So what should be protected has been protected, so what reason is there not to act?
