Who brought fire to mankind and what help did fire bring to mankind

In Greek mythology, it is said to be Prometheus.

Fuxi, but it was actually learned by people in the process of using forest fires.

In the primitive society, primitive people lived, and one day, a thunderbolt struck a tree and caught fire, and people felt very strange, and when they touched it, it was very hot and scared. Later, they used fire to roast meat, and found that cooked meat was better than raw, and from then on they learned to use fire. At that time, they relied on firewood to preserve the fire, and once the fire was extinguished, it was gone.

It was only later that it was discovered that wood was drilled for fire and flint was used to make fire.

1. Keeping humans out of the cold, early humans survived the cold winter by making fires;

2. For the early human beings to avoid the attack of wild beasts, fire is the most advantageous tool for primitive people to drive away insects, snakes and beasts in the dark night;

3. It provided cooked food for early humans, making the food more digestible and hygienic, and improving the physique and longevity of primitive people;

4. The development of human smelting technology, the use of copper, the use of iron, and the invention of pottery are inseparable;

5. Slash-and-burn farming, fire promotes the development of agriculture and increases the output of agricultural production;

6. Before the invention of electric light, fire was the most important lighting tool for human beings at night.

According to the available data, humans did not start using fire until 50.6 million years ago at the latest

The history of human development tells us that the use of fire is another epoch-making event in the journey of human beings to gain freedom after the making of stone tools, which has opened a new era of human beings to further conquer nature, so that fire has played a huge role in human conquest of nature.

First, use fire to aid in hunting. Secondly, fire can be used to process ** and tools, such as a wooden spear that is burned with fire and then cooled, and its tip becomes hard.

Thirdly, with the help of the use of fire, people learned to live in any climate, and humans spread to areas where they had not lived in the past.

Fourth, especially in the process of long-term use of fire, human beings found that the clay became strong and impermeable after roasting, and could also be fired into various utensils according to people's needs, which invented pottery. The success of pottery is the earliest meaningful application of human beings to the physicochemical changes of a substance (clay 0) under the action of fire.

Fifth, the development of primitive agriculture is also closely linked to the use of fire. At that time, agriculture was very extensive, but "slash-and-burn" farming played a very important role in the settlement of people.

With the improvement of fire technology, people began to smelt metals and use bronze tools. Later, due to the birth of blast technology, people further invented the smelting of pig iron. With bronze and iron tools, large-scale deforestation, the reclamation of wasteland, the development of agriculture and the development of pastures were possible.

In particular, the invention of modern firearms is the driving force behind the development of human history. You can imagine how terrible it would be if there was no energy and no fire now.

Thus, fire has given a powerful impetus to the development of social production.

Analysis: 1. Fire reduces the probability of human beings being infected by parasitic insects, pathogenic bacteria and viruses.

2. Fire allows humans to get food that is easier to digest, prolonging the time for the digestive system to serve us.

3. Fire keeps humans from the cold and the attacks of wild beasts.

4. Fire makes the nightlife of a large number of human beings colorful.

5. Fire makes human warfare more exciting.

The understanding, use and mastery of fire by human beings is the first practice of human beings to understand nature and use it to improve production and life. The application of fire is of great significance in the history of the development of human civilization.

1. The use of fire is an important sign of man's eventual separation from apes. Primitive people may have used fire at the earliest time when they were making stone tools or scraping wooden sticks, and gradually realized that flint would collide with sparks, and the friction of wooden sticks would also cause heat. After a long period of labor experience, people finally mastered the method of making fire.

2. Controlling fire to provide heat and light was one of the great achievements of mankind in the early days. Learning to use fire enabled humans to settle in colder climates.

3. The development of primitive agriculture is also closely linked to the use of fire. slash-and-burn farming, where fire promotes agriculture and increases yields; The use of copper, the use of iron, and the invention of pottery are all inseparable.

1. Yuanmou people will simply use natural fire.

Based on the excavation of two teeth, stone tools, charcoal chips, and later excavations of small stone artifacts, large amounts of charcoal chips, and mammalian fossils in the same stratum at the same site, prove that they were primitive humans who could make tools and use fire.

2. Beijingers know how to use natural fire and will preserve natural fire.

The caves where Pekingese lived were thick layers of ashes, up to 6 meters thick at the thickest point, and the ash heaps contained burned animal bones, tree seeds, stones, and charcoal blocks. It shows that Pekingese people already know how to use fire and preserve fire. The so-called natural fires used by the Pekingese are thunder that strikes dry wood and ignites the fire, or volcanic eruptions and forest fires.

Take turns watching the fire at night and use ash to preserve the fire.

3. The cave people at the top of the mountain learned to make fire manually.

In 1967, a "hole" was discovered at the north end of the 4th site of Zhoukoudian, called Xindong. In 1972, a road was built on the west side of the site, and part of the accumulation was dug up, and a layer of ash and more than a dozen mammal fossils were found. Formal excavations in 1973 revealed mammal fossils, a human tooth, the remains of fire, and dozens of stone tools.

The remains of the fire have a layer of ashes, which can be found at the bottom.

Most animals are instinctively afraid of fire, because the power of fire is so violent that a single fire in a primeval forest can kill countless animals and plants, and it is difficult to determine how humans have overcome this hurdle. Human beings began to use fire at least more than 1 million years ago, and some simple stone tools were found near the fossils of Yuanmou Man found in Yunnan, China, and a large number of charcoal chips were also found. Such discoveries have been found in many parts of the world, but they are still Homo erectus, have not yet evolved into Homo sapiens, have little to do with modern humans, and are a branch of ancient humans, but they can show that humans have a long history of using fire.

Other branches of humanity, including the direct ancestors of modern humans, presumably mastered the use of fire at that time. The fossil of Lucy, a hominid found in Africa, can prove that the history of Homo erectus can be traced back to at least 3 million years ago, and Lucy's skeletal features show that she has the same characteristics as a gorilla and humans, and her leg bones show the structure of walking upright, but her brain size is still relatively small, which also proves that the rapid evolution of human brain size occurred after walking upright. After primitive Homo erectus grasped the speculation that fire could have occurred in mountain or jungle fires, he found a large number of animal remains, which could be eaten and easily eaten.

After this phenomenon was discovered by primitive people, they began to actively apply fire. Since human beings use fire, food is easier to digest, primitive people do not need to spend a lot of time to bite food, after catching prey, throw it in the fire to roast, food is also easier to digest, bringing sufficient nutrition to primitive people, after which human brain capacity began to develop rapidly, correspondingly the stomach and intestines gradually shrank because of eating cooked food, and the function was slightly weakened. The application of fire is also convenient for primitive people to hunt at night, illuminate, and protect themselves, and when the weather is cold, a piece of roasting fire also promotes the development of human society.

From the Yuanmou people more than 1 million years ago to the Beijing people 500,000 years ago, they all left traces of fire. The people of Peking not only knew how to use fire, but probably already mastered the technique of preserving fire. Both the Yuanmou and the Pekingese used natural fire.

Early human beings used nature to obtain ** is natural thunder and lightning to make fire; spontaneous combustion of forest grass and trees to make fires; Spontaneous combustion of open-pit coal**; Occasional friction to start a fire.

The cave people have learned to make fire manually, which is a step forward from the past when only natural fire was preserved. After the invention of artificial fire, primitive man mastered a powerful force of nature, which promoted the development of human institutions and society, and finally separated man from animals.

This is discovered by human beings, lightning struck a big tree, the tree caught fire, crushing the animal, and accidentally found that the cooked meat is quite fragrant and delicious, and the cooked meat is easy to digest, and making fire can scare away wild beasts.
