How old is the primitive society?

By the end of 20 19, primitive society began about1700 thousand years ago and ended about 4088 years ago.

1. Primitive society is the first stage of the development of human society. The primitive society in China began with Yuanmou people about 6,543.8+0.7 million years ago and ended with the establishment of the Xia Dynasty in the 20th century (about 2070~ 654.38+0.600 BC).

Second, the stage classification

1, Paleolithic age

(About 2.5 million years ago-about 6.5438+0 million years ago) The early, middle and late Paleolithic period were roughly equivalent to homo habilis and homo erectus, early homo sapiens and late homo sapiens in the evolution of human physique.

2. Middle Stone Age

15000 to 10000 to 8000 years ago, stone tools were miniaturized, represented by stone chips and microliths. The transitional stage of human material and cultural development between Paleolithic Age and Neolithic Age.

3. Neolithic Age

The flourishing period of primitive clans began 8 000 years ago. The main tools are grinded stone axe, Shi Mao, chisel and shovel, grinded stone mill, hammered stone hammer, stone chips and stone tools.

4. At the end of Neolithic Age, human beings had used natural metals, and later learned to make pure bronzes.

However, pure copper is not as hard as stone tools, so it can't replace stone tools. This period is also called the age of stones and stones. From about 3000 BC to 2000 BC, human beings learned to make bronze and entered the bronze age. By 65438 BC+0000 ~ early AD, with the use of iron, mankind entered the Iron Age.

Extended data:

In primitive society, the social relations between people were adjusted by moral norms, religious norms, especially habits. Clan habits are gradually formed and evolved in people's long-term production and life, and passed down from generation to generation, becoming the internal needs and external conscious behavior patterns or behavior inertia of clan members.

These social norms involve public administration, marriage and family, property inheritance, fishing and hunting farming, product distribution, blood clan revenge and so on. For example, it is forbidden to intermarry, help each other, carry out blood clan revenge, organize fishing and hunting, collect and produce primitive agriculture, distribute products equally, hold religious ceremonies with the clan, and participate in the discussion and management of clan public affairs.

These social norms were determined by extremely low productivity, adapted to the social structure and social relations at that time, and maintained the order of production and life in primitive society.

The social norms dominated by habits in primitive society embody the common interests and will of all clan members, and rely on the prestige of clan tribal leaders, public opinion and people's conscious compliance to ensure their implementation.
