The dynamic of culture in the forest-steppe region of Ural-Ob basin

Basing on the synergetic methodology, the article considers the dynamics of culturein the forest-steppe region of the Ural-Ob basin in the 2000-500 B.C. During the Bronze Age, the Andronovo cultural and historicalcommunity (ACHC) is determined on all the territories of this region and includes the Alakul, Fyodorovo and Cherkaskul cultures. Inthe structure of the holistic dynamics of a culture the second of them may be recognized as its pre-bifurcation period. Around the 13thcentury B.C. the process of disintegration of ACHC, which resulted in the formation of the Cherkaskul antiquities and the Andronovocultures of the first order, may be identified with the beginning of the bifurcation (transitional) period. The bifurcation period is dividedinto three stages. The first stage is disintegration of ACHC and formation of the fractal structures (the bifurcation point). Thereupon, itwas proposed to extend the time frame of the transitional period till about the 13th century B.C. The Andronovo cultures of the firstorder were some intermediate forms, which developed into more stable formations - the Barkhatovo, Suzgun and Irmen cultures, whichmay be recognized as the beginning and expansion of the second stage of the bifurcation period. However, the endogenous dynamics ofthese cultures in the direction of chaotic processes absorption was interrupted by the migration of some northern population groups,which resulted in the second bifurcation point in the 9th-8th centuries B.C. No less than two trajectories of development within eachLate Bronze culture were observed in the content of the third stage of the bifurcation period. In the system of the Barkhatovo culturethese trajectories were presented as the formation and development of the east variant of the Itkul culture of the second type and theBaitovo culture. In the Suzgun culture one of these trajectories was represented by the Krasnoye Ozero antiquities; the second - by theZhuravlevo complexes. In the Irmen culture one of the trajectories is linked with the forming of complexes of the Zavyalovo type, a partof the early stage of the Bolshaya Rechka culture. The other is connected with the forming of the Early Sargatka antiquities. Thus, threealternative ways out of bifurcation were determined on the third stage of the bifurcation period: "the structure of the past", never realized;"the structure of the present" represented by the Krasnoye ozero culture; and "the structure of the future" embodied in the Baitovo,Zhuravlevo, and Early Bolshaya Rechka cultures, and the Early Sargatka antiquities. Transition to the last structure-attractor marked thebeginning of the post-bifurcation period of the development and linked with the forming of three Early Iron cultures by the 6th-5th centuriesB.C.: the Bogochanovo, Bolshaya Rechka and Sargatka cultures.
