1, Paleolithic:
The Paleolithic Age is a stage of human cultural development marked by the use of forged stone tools in archaeology, and it is the early stage of the Stone Age. It is generally believed that this period was about 2.5 million years ago-about/kloc-0.0 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 respectively.
2, the Middle Stone Age:
The age of making or grinding stone tools is called the Mesolithic Age, which is 15000 ~ 10000 ~ 8000 years ago. The miniaturization of stone tools is represented by stone chips and microliths. Will cook prey with the fire of nature.
3, the Neolithic age:
Neolithic Age is the last stage of the Stone Age in archaeology. Mainly grinding stone tools, which began about 6.5438+0 million years ago and ended more than 5,000 years ago to more than 2,000 years ago.
During this period, humans began to engage in agriculture and animal husbandry, sowing the fruits of plants and taming wild animals for food. Humans no longer rely solely on nature to provide food, so the source of food becomes stable. At the same time, the management of agriculture and animal husbandry has also changed human beings from living on weeds to settling down, saving more time and energy. On this basis, human life has been further improved, people began to pay attention to the development of cultural undertakings, and human civilization began to appear.
Extended data:
The Stone Age is a period of time assumed by archaeologists, which is an archaeological term. The Stone Age is divided into Paleolithic Age, Mesolithic Age and Neolithic Age. The first archaeological stage of early human history, that is, from the appearance of human beings to the appearance of bronzes, began about two or three million years ago and ended about 50 thousand to 20 thousand years ago.
This name was first put forward by British archaeologist lubbock in 1865, when the geological age had entered the Holocene. The Stone Age is only a concept of time profile, which does not mean that people only used stone tools at that time. According to a large number of cultural relics unearthed in modern archaeology, thousands of years ago, the ancients entered the civilized period of smelting and casting, rice planting, pottery making and textile. Bronze and iron are metal products, and few have been preserved for thousands of years; Pottery and jade can be preserved for a long time, and there are many unearthed relics.
