It is accepted to call sharp changes in any given area of human life revolution. This term, in view of depth of the sense, is often spliced with the supplementing definitions which, as a rule, correlate it to that silt other field of knowledge. For example, historians use the concept "neolytic revolution".
Neolytic revolution took place owing to transition from the appropriating economy to making, i.e. is based on transition of human communities from hunting and collecting to agriculture which, depending on the region, took the forms of agriculture or livestock production. Earlier people only took away from the nature made by it, now they began to make what was not in the nature (new plant varieties, house animal species). In various cultures the transition to agriculture happened within 10 – 3 thousand years BC. This term was entered by the English archeologist of the 20th century Gordon Chaild who expressed point of revolution as emergence of control of people over own food stocks.
The settled type of accommodation, emergence and storage of stocks of food, emergence of cycles of work and expansion of activity of tribes turned out to be consequence of neolytic revolution.
Neolytic revolution led to emergence of constant settled settlements, made life of settled tribes more independent of the surrounding nature and neighbour's tribes. The number of groups of people expanded since food was mainly got on one place. The population of similar ancient settlements began to transform the environment surrounding them by agrocultivation of the earth, a vozveleniye constant all of the expanding settlements. Increase in amount of food led to growth of the population, and it, in turn, caused division of labor, to emergence of barter, formation of the power supported with armed forces. The common property of grounds dominating before revolution for collecting and hunting upon transition to settled type of life and cultivation to the number of the earth limited territorially when the fertile earth became a rare resource, led to emergence of a private property on the earth. At settled life there is a need of protection of settlements and allotments from neighbors, solutions of internal contradictions because of the earth in community. All this became prerequisites for development of the state which main function was a protection of a private property. Increase in life expectancy, settled life caused formation of a system of knowledge which was imparted in the beginning orally, and then developed also into emergence of writing. Thus development of agriculture caused development of society, and, further, an ancient civilization.
