How did primitive agriculture, animal husbandry and handicrafts come into being?

First, the emergence of primitive agriculture. In the process of collecting wild food crops for consumption, primitive humans will throw some fruits on the ground. After a long time, they found that some fruits can produce grains after being covered with soil. After countless experiments, they gradually mastered the agricultural planting technology, and agriculture came into being.

Second, the emergence of animal husbandry. When primitive humans were hunting, some captured animal cubs were too small to eat, so they were left as toys for children to play with. Later, these cubs gradually grew up. When someone wanted to eat, everyone didn't want to get along with these animals for a long time, so they didn't do it. When these adult animals mate with each other and give birth to new cubs, some clever humans find that livestock food can be obtained through artificial reproduction. After many experiments, they gradually mastered livestock.

Third, with the emergence of handicraft industry, human beings entered the Stone Age. When bored, they occasionally beat such small stones, bones or wood on big stones for fun, so as to kill time. One day, they suddenly found that they could change the shape of stones or bones or wood through this kind of beating, and then create the material form they needed. Since then, human beings have changed from unconsciously beating stones, bones or wood to consciously processing these raw materials.
