Fire is a phenomenon in which light and heat are emitted during the burning of substances, and the temperature is very high, which is a way to release energy. It is only a way of energy release, which has nothing to do with the entity. However, it is this way of energy release that affects the development process of the whole human beings invisibly. In romantic western legends, Prometheus stole heaven and fire for mankind, making mankind the spirit of all things. In the ancient history of China, Suiren's drilling for fire made human beings get rid of eating animals and drinking blood, thus creating the Chinese civilization. At the same time, in ancient Chinese philosophy, it was believed that Jin Mu's five elements of fire, water, soil and mutual restraint formed everything in time; In the far west, Empedocles believes that four elements, water, air, fire and earth, constitute everything in the world under the action of force. Whether in the ancient and mysterious East or the romantic West, fire is the origin of civilization and the cornerstone of world civilization. The quality and strength of fire in human civilization have been recognized by the whole mankind. Man's understanding, use and mastery of fire is the first practice that man understands nature and uses it to improve production and life. The application of fire is of great significance in the history of human civilization. From Yuanmou people more than 1 million years ago to Beijingers 5, years ago, they all left traces of using fire. Humans used natural fire at first. After the invention of artificial fire, primitive people mastered a powerful natural force, promoted the development of human system and society, and finally separated people from animals. Fire is one of the important means of primitive hunting. It is effective to drive and encircle wild animals with fire, which improves the hunting production capacity. Burning grass for fertilizer and promoting the growth of weeds are naturally inherited by later nomadic tribes. The original agricultural farming method-slash-and-burn was carried out by fire. As for the primitive handicraft industry, it is inseparable from the role of fire. Bows, arrows and wooden spears have to be roasted with fire. In the future, pottery and smelting can't be completed without fire. ? At the same time, the appearance of fire has imperceptibly affected human diet. With the appearance of fire, the cooking techniques of food have been improved and developed in the long historical development of mankind. Humans completely got rid of the primitive life of eating animals and drinking blood. In the following thousands of years of culture, fire directly promoted the development of eastern and western food culture, and also promoted the prosperity of the eight major oriental cuisines. On the other hand, due to the use of fire, raw food has gradually faded out of human vision, and the appearance of cooked food has prolonged the average life span of human beings and improved the quality of human life to a certain extent, thus transforming and utilizing nature for a long time? With more powerful power and abundant time, it has accelerated the pace of human beings getting rid of primitive and moving towards civilization. While fire benefits mankind, it also brings disasters to mankind by virtue of its infinite power. As early as the Spring and Autumn Period, mankind began to struggle with the disasters caused by fire. Among them, Confucius, a famous politician and thinker in the Spring and Autumn Period and the Warring States Period, went to the scene of the fire several times, bowed to the firemen personally, and took the initiative to care about the situation of the firemen, showing his awareness of fire prevention and fire rescue. When Mozi, a politician and thinker of the same period, was young, he organized a volunteer army of 3 people as a civilian to defend Song Cheng and resist foreign invaders from attacking the city with fire. He also put forward a series of fire prevention measures, such as painting mud on the city gate, making a water bucket with linen, making a water tray with leather, and setting a water reservoir on the city gate. Since then, fire, as another killer in human history, has been on the battlefield, which has brought great harm to mankind. Fire has contributed its own light and heat to mankind at an important moment in the development of human history. Fire has accompanied human beings through a long history of millions of years. Whether it has brought warmth, food or disaster and pain, fire has always been a driving force for the development of human beings and science. The history of human beings begins with the correct use of fire. What is the significance of the use of fire to human civilization and progress? Ask God for help.
Humans have changed from being raw to being cooked.
What is the significance of the use of fire to human evolution?
First, the meaning of fire. 1. Eating cooked food is easy to absorb, which makes the ape-man get richer nutrition. Cooked food and boiled water make the ape-man less sick; 2, slash and burn, fire promoted the development of agriculture and increased output; The use of copper, the use of iron and the invention of pottery are inseparable from fire; 3. Fire is the most advantageous tool for primitive people to drive away insects, snakes and beasts in the dark; Second, as for the factors that play a positive role, people often mention labor, which not only exercises the ape-man body, but also exercises the ape-man brain. The body and brain accumulated from quantitative change to qualitative change, so at a certain moment, human beings were born. But I think the role of natural selection is also very great. Natural selection screened out the inappropriate genes of ape-man, which is a very effective gene filter. The other is the natural environment, and the end of the ice age brought plenty of food. So I think the main factors are: 1. Labor (or survival process), 2. Natural selection, and 3. Suitable living environment. Follow-up: What are the options for the answer? What's the benefit of the use of fire to human evolution?
The use of fire is an important sign that people finally get rid of apes. There are traces of carbon scraps in the site of Yuanmou ape-man in China 1.7 million years ago. Paleoanthropologists in China also believe that Beijingers 23,-46, years ago already knew how to manage fires and protect kindling. However, the most typical relic of using fire was found in the cave at the top of Zhoukoudian Mountain in Beijing, and its ash was several layers * * * several meters thick. The ashes of primitive people using fire were also found in Zealous, Huertes. Primitive people may have used fire for the first time when they were making stone tools or scraping wooden sticks, and gradually realized that sparks would appear when flint collided, and the wooden sticks would generate heat when rubbed. After a long period of labor experience, people finally mastered the method of making fire. Perhaps in the late Paleolithic period, as primitive people learned grinding technology and drilling technology, they also mastered the method of drilling wood to make fire or beating fire, which realized a great creation in human history. The use of fire has brought revolutionary changes to the production and life of primitive people. Pottery was born with the use of fire. The kiln pits and fired pottery figures of people and animals discovered by Daulny Vestoni in Czech Republic existed 28, years ago, indicating that human beings had pottery-making technology at this time. The great significance of writing to human beings is that < P > it promotes the transmission of human information and marks the birth of human civilization!
How does the use of fire help human evolution?
Cooking food is easy to digest and absorb.
Being able to use fire is an important difference between human beings and animals. In the early days, people baked food with fire to eat, thus improving the nutrition of their bodies, benefiting the development of their brains, and their brains became more and more developed, greatly enhancing their ability to survive in nature. What is the historical significance of the use of fire to mankind?
The use of tools is a symbol that distinguishes human beings from ordinary animals, and fire provides a necessary condition for the development of pottery and metal tools. At the same time, the use of fire makes human beings eat cooked food, prolong their life, speed up their evolution, and begin to break away from the Stone Age and enter the bronze age. What is the significance of the use of fire to human development?
Fire is a phenomenon produced in the process of burning substances, and the light and heat it emits are the way to release energy.
There is a strong oxidation reaction in the flame, which can have different shapes with the vibration of particles. The high temperature part above the flame appears in the form of plasma (the fourth state, similar to gas). Fire must have combustible, ignition temperature and oxidant to make a fire, and all of them are indispensable. According to the law of conservation of mass and energy, fire does not make the burned object disappear, but only changes the molecular form of the burned object through chemical reaction. When a fire is out of control, it is often called a fire or a fire.
burning wood was the earliest way to make a fire. Trees have provided a lot of energy needed by human beings since ancient times, so they are called firewood or firewood. Different trees make different firewood. "Tiaodingji Fire" lists all kinds of firewood cooking: "Mulberry firewood: cooking food is beneficial to people. Cooking old duck and meat can make it extremely rotten and can solve all the poisons. Dirty firewood is not suitable for food. Rice Spike Fire: When cooking and eating, people are fascinated by the five internal organs. Wheat ear fire: cooking and eating, quenching thirst and moistening throat, and facilitating urination. Loose firewood: cooking, strengthening bones and muscles, not cooking tea. Oak firewood: cook pork and eat it, without moving the wind, and cook chicken, duck, goose, fishy smell and other things rotten. Mao firewood: the cook's diet, the main eyesight and detoxification. Reed fire and bamboo fire: all tonics should be decocted. Charcoal fire: it is advisable to fry tea, which is delicious but not turbid. Bran fire: rice bran fire cooking diet, supporting the ground stove, can support two pots, southerners use it more, and its cost is half that of firewood. In the spring, insects enter the chaff, which is fatal. "
in modern times, people use thermal power to generate electricity, and coal, oil and natural gas are used as fuels to generate electricity. What fire did cavemen use? What does the use of fire mean to mankind?
Humans can use fire to heat food, eliminate parasites and germs in food, and reduce the probability of human being being infected by pathogens.
The nutrients in the heated food are more easily absorbed by the human body.
People can use fire to keep warm so that they can live in cold regions.
Humans can use fire to drive away wild animals, which can be used for hunting and prevent humans from being hurt by wild animals.
