What is the symbol of the rise and development of primitive agriculture?

The important signs of the rise and development of primitive agriculture are the emergence of crop planting, livestock raising and the development of settlement and grinding tools.

The rudiment of primitive agriculture appeared in the early Neolithic period in China. The sign of entering primitive agriculture is the appearance of rice and pottery, and the major technological breakthrough is the domestication of wild animals and plants.

In the Neolithic Age, due to the change of ecology and the increase of population, the wild animals and plants in nature could not meet the needs of our ancestors, so human society began to produce seeds of agriculture and animal husbandry, and created a "slash and burn" agricultural civilization.

The basic characteristics of primitive agriculture are:

1, the production tools are simple and backward, mainly stone knives, shovels, hoes and sticks.

2. The farming methods are primitive and extensive, and slash-and-burn farming methods are adopted.

3, mainly engaged in simple cooperative collective labor, access to limited means of subsistence, to maintain a low level of * * * and life needs. Slash-and-burn is the farming technique of primitive agriculture. This farming technique has been preserved in some modern nationalities. This farming method was also preserved in the Yangtze River valley in China for a long historical period before the Tang and Song Dynasties, and was called "Shetian".
