In recent decades, humans have invented antibiotics, pesticides, televisions, radars, engines, atomic reactors, electronic computers, ......All this constitutes today's highly developed technological environment, also known as the "second nature", which allows the material on Earth to grow at an alarming rate, doubling its amount approximately every 15 years. In today's world, humanity is facing the serious challenge of building a technological environment for itself.
The evolution of the biological organism is extremely slow compared to the rate of change in the technological environment. Archaeologists and anthropologists agree that hominids are not much different from modern humans in terms of brain structure. For thousands of years, there have been no differences in how people respond to language.
Basically, you usually accept one word per second. However, it has not been half a century since the world's first electronic computer was calculated at 5,000 times per second to the current large-scale electronic computer with billions of operations per second.
Can the human brain adapt to the rapidly evolving technological environment? Some even believe that in the future, AI may completely replace natural intelligence. Is that really the case? Knowledgeable people in the scientific community are positive about the first point and negative about the second.
The brain is an inexhaustible source of human intelligence. With more than 14 billion neurons in the human brain, it constitutes the most complete and efficient natural system on earth, a wonderful creation of nature that cannot be surpassed by any of the most advanced information technology tools or artificial intelligence invented by man.
In short, although the technological environment created by human beings always poses serious challenges to its masters, in the process of using and transforming the natural world, human beings will always be the masters of the technological environment.

Productivity levels are two concepts.
Primitive man pursued survival.
Nowadays, however, people generally enjoy it.
-
We don't have any of them now, so if you think about it, there is no house to live in, no electricity, no electrical appliances, no mobile phones, no clothes to wear, no cars, and there are not many things.
-
Primitive people wore tree bark and animal skins, ate wild fruits and beasts, lived in caves, and walked on their legs.
-
Pekingese Man: Primitive humans found in Zhoukoudian, southwest of Beijing, China.
-
Our ancestors must have lived in the wild and fed on the fruits of animals or plants they could hunt. Mainly on both feet when it comes to walking. Wear mainly leaves or animal skins!
-
In ancient times, human beings mainly relied on hunting to live, and there were few clothes to live in, mainly grass huts and grass huts to travel, mainly not work.
-
It is guessed that the ancestors of human beings are very simple primitive humans in terms of clothing, food, housing and transportation.
-
1. Clothing: The clothes of primitive people are mainly leaves and animal skins, mainly to cover shame and keep warm.
In addition to covering shame and keeping warm, modern people's clothes also pay attention to beauty and comfort.
2. Food: primitive people mainly used raw meat or semi-raw meat.
Modern people's food types are more diverse, mostly cooked food, and there are great regional differences.
3. Living: Most primitive people sleep in tree holes and stone caves, as long as they can shelter from the wind and rain.
Modern people should live beautifully and comfortably.
4. Walking: Primitive man walked on 4 limbs or 2 feet.
In addition to walking, modern people mostly use means of transportation, such as cars, boats, airplanes, etc.

In the 60s of the 19th century, archaeologists discovered the ruins of primitive people in Yunnan Province. The site is known as the "Yuanmou Man" in ancient times about 1.7 million years ago. According to relevant evidence, the "Yuanmou people" were the first humans to use fire, and archaeologists found from the site that there were many traces of burned carbon chips and animal bones.
At that time, human beings mainly used natural fire, and the main natural fire was the forest caused by volcanic eruptions, lightning strikes, etc. Natural fire is limited after all, but primitive people have found many benefits from "fire", such as grilled food is more fragrant and easier to digest. So primitive people spontaneously thought about how to preserve the fire so that it could be used when there was no natural fire.
After a long time, primitive people discovered the method of drilling flint to make fire. Archaeologists speculate from the stone tools used by the Beijing ape man in Zhoukoudian that the time when the ape man consciously used fire was about 500,000 years ago. Mainly friction**, such as striking flint or stone tools will produce sparks; Scraping and drilling wood will generate heat, etc.
The use of fire is a great advance in human history.
-
The tools of primitive people are very simple, and there are many fierce beasts around them, and they will be injured at any time and anywhere.
Harm. Later, they saw birds making nests in the trees, and the wild beasts could not climb up and could not harm them. Primitive man followed the example of a bird and made a nest in a tree, that is, a hut in a tree.
It's much safer that way. Later people called this "Tsugi for the Nest" (nest cháo, that is, bird's nest). Who invented it?
Of course, everyone figured it out together. But in the legend, it is said that there is a person who taught everyone to do this, and his name is "Youchao". At that time, there were no silk products, and clothes were made from animal skins!
Food] People in primitive societies made a living by hunting! At that time, flint and steel came to make fire! 【Live】They all live in caves and live in groups!
Row] group activities are the main, there is a leader!
-
Primitive people existed for a long time, lived backwardly, and they divided into many independent tribes, each of which was governed by a chief. They have great respect for the elders and elders, and the tribal council of elders is still the most prestigious authority to this day, and major tribal issues are to be decided by the council of elders. At the beginning, it was a matrilineal society, (that is, a female respect) and later a patriarchal society, using stone tools and simple tools, they never violated others for no reason, but when they were violated, they would not hesitate to pick up ** for self-defense.
It's still a relatively simple life.

In the earliest primitive human life, there were no marriage rules, and at that time, there was no way to talk about the weak material civilization and spiritual civilization. By the Paleolithic Age, the social division of labor appeared into different groups of people. The organization is maintained primarily by kinship, which is the pre-clan commune era.
There are some differences in the status of the older and younger, but there is no intermarriage between different generations. Marriage at this time is called the blood family system. In the late Paleolithic Age, when primitive people sewed statues, there were brothers and sisters who could not intermarry, and later developed to the point that collateral brothers and sisters could not intermarry, and the marriage family at this time was called group marriage family.
In the early days of clan society, people only knew their mothers, but not their fathers, which was the period of matrilineal clan society. However, with the development of productive forces, the matrilineal clan system is not suitable for the needs of social development, and intermarriage outside the clan has been recognized and developed. The previous institution of marriage was called "wangmenju", in which one wife had one husband among many husbands and one man had one wife among many wives.
However, couples still live in their own clans.
-
Habitation: semi-crypt, cave, ......etcPrimitive people were relatively poor in adapting to their environment, and they lived in groups to escape the attacks of wild beasts, because they had not yet learned to use fire. Moreover, the food hunted by the group would be shared collectively, because their food was quite scarce at that time, and even if they lived in the group, people would still starve to death.
Group life is still a need for survival.
Won't farm, won't farm.
They can only live by hunting and gathering wild fruits.
There is no hierarchy, no commercial activity.
Able to make and use some simple tools (stone tools).

The life of primitive people on the biological level and the social level, etc.
1. Physiological level.
In terms of brain capacity, the average human brain volume is now 1250 ml, while 10,000 years ago, the average brain volume of Homo sapiens was about 1300 ml, while the brain volume of Neanderthals was generally around 1250 ml.
Many of the stone tools used by Neanderthals have a distinct Homo sapiens color. This shows that there is a considerable degree of communication between the various human races in the same area. It's not completely closed.
At present, there is a consensus in the academic circles that language and writing are the necessary elements of a civilization, and only when a systematic language and standardized writing are produced, can a text or Nai Jingming be called a civilization.
2. Social level.
In terms of spiritual pursuit, primitive people are not as cold-blooded and ruthless as we imagined, but have a strict social family structure and spiritual and cultural pursuits.
For example, in the funeral, the funeral of primitive people is not like other animals who die and return to the acres and are buried in the sky waiting for hyenas and vultures to eat, but will dig a grave pit like modern humans, and put bedding materials such as leaves underneath, and then put the body on it, cover it with sealed soil, hold a funeral ceremony, and bid farewell to relatives and friends.
Characteristics of human life in different periods:
1. Early ape-man stage: It lived about 3 million to 1.5 million years ago, and already had the basic characteristics of human beings, able to walk upright, and make simple gravel tools.
2. Primitive humans: about 2 million to 300,000 years ago, the body is like a human, the brain is large, can make more advanced paleolithic tools, and began to use fire, such as the Beijing ape man in Zhoukoudian, Beijing, China.
3. Early Homo sapiens: 100,000-200,000 to 50,000 years ago, it gradually broke away from the characteristics of apes and was very close to modern humans, such as Neanderthals in Germany.
4. Modern man: About 40,000-50,000 years ago, the evolution of human beings at this time has accelerated significantly, and it has been very similar to modern humans in form.
3. Primitive tribes still exist, but they are gradually assimilated by society. In fact, the United Nations has always been concerned about the people's lives in backward areas of the world, and most of these backward areas are relatively backward countries or primitive tribes, and fundamentally primitive people may still exist in some relatively remote places, but the possibility of primitive people is getting lower and lower. >>>More
It depends on what period of primitive people. Early hominids, that is, primitive humans more than 100,000 years ago, were between modern humans and apes, with a somewhat protruding mouth, a collapsed nose, and heavy hair. >>>More
The trick is not much, the main thing is to give birth to children with enough food, and the tribe is to grow. Collect fruit and collect less points, give it to the old apes and young apes, and the rest of the manufacturing ** to hunt, at the beginning the tribe rarely hunts some rabbits, and the efficiency will become very low in rainy or snowy days, and it is not recommended to hunt in the case of sufficient food to let lovers rest and get pregnant or something. If you stay in the same place for a long time, you will have less food, so it is best to move in the direction of the stone cup to reach the game. >>>More
After watching this funny film, there is one place where everyone's feelings are touched. That's when Guago, the father of primitive people, throws his family into the new world, and he is lonely, helpless, and wounded in despair. >>>More
The term cancer first appeared in the middle of 400 BC. Proposed by abcd, the father of Greek medicine (I'm too lazy to type). 。 >>>More
