The Neolithic revolution is a concept that appears to define the transformations of society that would lead to the adoption of agriculture and the rural way of life as the main economic base of human social groups. That is, it is passed to an economy that has as its main base the production of food instead of the previous life of hunting and gathering. This change of life towards the Neolithic was a transformation in the life of prehistoric man.

Therefore, the Neolithic revolution would be the radical transformation of the way of life of the human being. The human being will go from being nomadic to sedentary. It will go from having an economic base of hunting and gathering to having a productive economic base through agriculture and livestock.
