It is called prehistory to the human period that developed before the emergence of writing . That is why it can only be known through bones, tools, remains of buildings and other elements, but not from documents of the time.
Prehistory is usually divided into ages (temporary stages). The cycle that started about 2.8 million and it extended approximately until the year 3,000 BC it is called Stone age , since it is characterized by the elaboration of utensils and instruments with said material.
Following these clarifications, we can focus on the definition of Neolithic . This is what the last period of the Stone age , developed after the end of Paleolithic . While in the Paleolithic the prehistoric human being began to carve rustic stone tools, in the Neolithic started appealing to polished and to perfect their creations.
Technical innovations, therefore, are one of the main features of the Neolithic , where changes in the social and economic structure were also introduced. During these years, agriculture and livestock were extended, with agrarian societies emerging. In this way the man he went back sedentary and was leaving aside nomadism.
It is important to keep in mind that the Neolithic did not advance in the same way in all the world . In general, it can be said that, due to climate change and little by little, the human being went from hunting (subsistence economy) to agricultural and livestock tasks.
The end of Neolithic also marked the closure of the Stone age and the beginning of the Age of metals , which is usually divided into Copper Age , Bronze Age and Age of Iron .
