There was no fire in ancient times, so how did humans survive?

First of all, to clarify, fire has not only served to cook meat, in human history.

In the early days, there were many roles.

1. Drive away wild beasts.

Before learning to use fire, ancient humans would use all kinds of stone and wooden sticks to make ** and cooperate on a large scale, but without fire, it would not be so efficient in driving away wild beasts, and it would cost some money.

2. Store drinking water.

Without fire as an energy source, there would be no way to burn pottery and porcelain, drinking water would have to follow the water source, and humans would not be able to settle down.

3. Form words.

Without fire as an energy source, the clay tablets with symbols carved into them are just clay tablets, which cannot be stored and transported, and it is difficult for information to be transmitted through words.

4. Open up wasteland for farming.

Even if ancient humans knew that sowing a certain plant can harvest a lot of grains, these can resist evil when chewed, and there is no fire to remove weeds, and it is very inefficient to pull them out by hand.

5. Enhance physical fitness.

Eating more cooked meat has indeed made great progress in the physique of ancient humans than before, and some bacteria and viruses that are easy to cause gastrointestinal diseases.

The parasites were all boiled to death, but the old and small children had a hard time eating raw meat without fire.

Therefore did not learn to use fire, ancient human civilization.

The fire is swaying in the wind and rain, and it may be extinguished at any time.

In ancient times, human beings should not have been enlightened enough to compete with other species for control of the earth, but they were all struggles and efforts for survival and species continuation (biological instinct), competing for living space and resources, and there may be many complementary ones. Perhaps before humans become human beings (using tools and fire), omnivorous makes it less susceptible to loss of food due to climate change and natural disasters and extinction (by the natural environment.

I think maybe human beings are lucky, in ancient times we probably never thought about ruling this so-called earth or necessarily defeating other species, we just wanted to live and live.

Just like now.

Without fire, human survival is very difficult, but there are also some things that can play the role of fire, such as you can wear animal skins to keep warm, you can make simple self-defense, you can live in groups to reduce the danger, but there is no doubt that the living environment of human beings without fire is very bad, and the emergence of fire is a great progress in human history and improves the living environment of human beings.

Ancient humans in ancient times hid in caves, eating raw meat and drinking raw water like ordinary animals, and because they needed to bite raw meat, ancient humans had wisdom teeth, and their teeth were also very large, and the whole face was protruding, similar to monkeys. Later, after ancient humans used fire, it changed a lot.

In ancient times, human beings were social animals, all of them were divided into a group, and people would go out to hunt in groups every day, and they lived like this.

Human civilization has a long history, and in the long history of human development, our ancestors used their outstanding wisdom to survive in extremely harsh environments, which is an example worth learning from. So today, let's take a look at how our ancestors survived and multiplied in the cold and snowy environment in ancient times. <>

In ancient times, the living conditions were extremely harsh, and various extreme weather occurred frequently, resulting in the life expectancy of our ancestors was generally very short, only twenty or thirty years. Of course, this does not include some examples of predators coming to attack or dying of illness. But it was under such harsh conditions that people in ancient times learnedUse fire

The use of fire ensured the lives of our ancestors, who could use open flames to drive away predators and wild beasts, and also used open flames to heat food, which greatly reduced the chance of ancient humans getting sick. At the same time, after humans eat baked food, their brains develop and their physical fitness becomes better and better. Such conditions allow them to survive better in extreme conditions.

Learn to use toolsWhen our ancestors learned to use fire, their intelligence developed rapidly, and gradually they mastered some simple tool-making, and entered the Stone Age. They began to use stones to make attack objects and various tools. In this way, the defense capacity of humans in ancient times has been greatly improved, and the invasion of humans by wild macroorganisms has been greatly reduced.

The improvement of the tools has greatly improved the hunting skills of our ancestors, and some other small creatures are often caught for consumption. It greatly improves the survival ability of human beings, as well as the ability to reproduce. When food is sufficient, the ability to reproduce is greatly improved, so that human society is gradually formed, and with various division of labor, human civilization has begun to develop rapidly.

How's that, do you all understand? <>

Because the human ancestors had very strong survival skills in the wild, they experienced a lot of disasters and gained a lot of experience, so they were able to survive.

Human ancestors continued to develop their human civilization through hunting, living in groups, such as drilling wood for fire, men farming and women weaving, and adapting to the environment through continuous exploration, and finally surviving.

Our ancestors were very adaptable to the environment, and they used all kinds of things, so it was very easy to survive.

They have a lot of skills, they are very wise, and they can make good use of their advantages to make their lives better.

By helping each other, learning how to make tools, cooking food, and communicating in words.

In ancient times, when there was no fire, people were completely full of hair and blood, and man and beast were not civilized at all. At that time, people ate raw food, and the conditions were very backward.

Eat raw things, and in order to live, you have to eat raw things.

Eat raw, dry nibble and chew with your eyes closed.

Before us, the earth was still in a relatively initial situation of the Gao cavity, the earth is a very large and rich life star, there are many flowers and trees on this land, this kind of flowers and trees have not been harvested by human beings, and traces of being covered by mountains and forests can be seen all over the ground. It can be said that at that time, the main feature of the earth's ocean, except for the blue ocean, was the green forest. There were no humans in ancient times, so if there were forest fires, would they burn all over the world?

1. The main causes of forest fires.

The first point of the premise is about the outbreak of forest fires, the key is that there are many reasons, forest fires will break out, probably because many dry flowers and trees will become dead wood after receiving ** after being roasted at a high temperature in the sun, and dead wood is particularly flammable. If the temperature of the living environment of the internal structure is too high, this kind of dead flowers and trees will cause **. In addition, lightning caused by temperature such as lightning can split flowers and trees, causing flowers and trees to ignite immediately, which is also the main cause of forest fires.

The scope of each forest fire is enormous.

2. Forest fires do not necessarily burn the whole world.

Secondly, and on the other hand, forest fires do not necessarily burn the whole world, although in ancient times there were no other animals on the earth, and there were no such unexpected elements as people. Ancient forests are still not necessarily able to burn the entire earth, for example, in Russia and Australia, where the weather is relatively cold, and the flowers and trees in various regions are also covered by all kinds of thick wind and snow, but the burning ability of these flowers and trees is very low. Therefore, when the forest fire burns all over the village, the flowers and trees will not necessarily be ignited due to the influence of the fire.

3. Natural causes can also assist in firefighting to a certain extent.

In the end, if there is a cause of forest fires in nature, there are certain countermeasures to help fight the fires, such as the various precipitation climates that we usually see, and the full-scale outbreak of lakes. Forest fires can cause vapor to soar upwards, and when the vapor condenses in the clouds, it causes small droplets of water that will land on the ground.

No, because it rains, and the forest area is finite, not globally connected.

Of course, in ancient times, if there was a forest fire, then it would directly ignite all the trees, unless there was a bridge and heavy rain could stop such a fire.

Of course, this is impossible, sometimes it will rain in some areas, and naturally it may extinguish the fire, and sometimes it will also encounter large rivers.

In ancient times, because of the backward level of science and technology and the severe cold, human beings did not have a good living conditions. But in such a situation,Our ancestors learned how to use the tools, and with the help of the team, we managed to get through it.

1. Our ancestors learned how to use tools

In ancient times, the physical strength of humans was really not worth mentioning compared to some beasts of prey, and until now there are many beasts of prey that can easily kill humans. However, because our ancestors recognized the importance of tools and learned to use them, they were able to hunt better and obtain food and animal skins more easily with the help of tools, even when individuals were not very capable. And after the human ancestors learned to use and create fire, this also gave them the capital to survive in the bitter cold, plus clothes made of animal skins and some simple shelters, which also allowed them to withstand the cold.

In addition, with the improvement of tools by human ancestors again and again, human society gradually has the capital to gain a foothold in the world, and civilization has gradually begun to develop, and at the same time, human beings have survived that difficult period, which is what human society is today.

2. Team assistance

Human beings are social creatures, and according to some murals and symbols left by ancient humans, it can be interpreted that human ancestors have learned team assistance a long time ago, such as teamwork hunting, teamwork roosting, etc. In such a case,Although a single human ancestor did not have an individual advantage, once multiple people cooperated, both hunting efficiency and survival efficiency were greatly improved, which also allowed human ancestors to survive in the cruel environment at that time. And as the human ancestors continued to reproduce, the prototype of the village was gradually formed, and then civilization was slowly produced, and then slowly developed, and finally the current human society was formed.

Overall, the fact that our ancestors survived had a lot to do with the fact that they learned how to use tools and how to work as a team.

The ancestors of human beings were supposed to survive day by day, and the ancestors of humans would also hunt beasts of prey and make clothes to keep themselves warm.

The ancestors of mankind survived with wisdom because they would solve the problem with wisdom rather than reflexively by force, so they survived in the end.

The ancestors of mankind passed very difficult tests, broke through the limits, and experienced many disasters before finally surviving and developing to the present era.

Generally, the heat is increased by lighting a fire, wearing more clothes, and the warmth of the body is also increased by exercising.

The use of fire is the history of human evolution.

Copy the mileage.

Bai stele, the earliest artificial taken by human beings.

The fire methods are "drilling wood zhi to make fire" and "hitting stones to make fire".

dao1, drill wood for fire:

The legend of drilling wood for fire was invented by the Suiren clan. He saw that when birds pecked wood, friction produced sparks, so he was inspired to invent drilling wood for fire. After humans learned to make fire artificially, more ways to heat food appeared, and the era of Ru Mao drinking blood came to an end, and "cooking" gradually appeared.

2. Hit the stone to make fire

According to legend, striking stones to make fire was an invention of Emperor Yan in ancient times, and it may be that primitive humans were inspired by the phenomenon that stone strikes produce sparks when making stone tools, and gradually mastered striking stones to make fire.

Drill wood for fire, hit stones for fire
