Pursuant to the reproduction theory and the set theory the concept was elaborated, that throughout the historical evolution of mankind five basic forms of society (called by the author - forms of the sustaining sphere) have emerged consecutively: consumptionarity, protoeconomy, economy, market economy and financial market economy. They are integrated in each other in such a way, that each subsequent historical form creates and complements a new phase of reproduction, including the previously emerged ones. Thus the historical evolution is projected in the logic of each current form of society. Consequently a new periodization of the material life in human evolution was proposed, set up of five stages: non-protoeconomic consumptionarity, non- economic protoeconomy, non-market economy, non-financial market economy and financial market economy. Protoeconomy and economy are not identical notions, as protoeconomy is a wider concept than economy, which is just a special case thereof.
