Primitive agriculture: Primitive agriculture evolved directly from the collection industry. People have planted the fruits of wild plants that they had already depended on for a long time with a digger or stone hoe on the land where the thorns of the trees were burned with fire, and they were harvested when they matured.
The invention of wooden ploughs and the use of cattle, horses, and donkeys for farming was later. Primitive agriculture is a conscious application of the knowledge of biological growth processes accumulated in life. It can be harvested after sowing, and it is also a strong proof of human s understanding of causality in practice. Due to differences in natural conditions, the crops cultivated around the world are different. The earliest people in Southwest Asia began to grow wheat and barley, the earliest Chinese people began to plant millet and rice , and the hometowns of corn, potatoes, and pumpkin were in Central America and Peru.
Primitive animal husbandry: Primitive animal husbandry was developed from hunting activities. This is to raise some easy-tamed animals that have been hunted, and let them reproduce under domestic conditions.
The earliest domestic animals domesticated by humans were sheep, then dogs, and later goats, pigs, cows, donkeys, elephants, horses, camels, and so on. Compared to gathering and fishing, the emergence of primitive agriculture and animal husbandry was an industrial revolution. Because it shows that human beings have jumped from relying solely on natural gifts to move to increase the production of natural products through their own activities.
