| Abstract: |
The principal transition of a prebiotic microsystem into a primary living unit proceeds through three stages. succession of transformations is theoretically substantiated. For 1st stage significant change of the external conditions turns a prebiotic microsystem at the point of bifurcation (the unstable intermediate position between the current and advanced stable states). During 2nd stage its unstable state relatively stabilizes by means of the balanced oscillations around the bifurcation point (the microsystem acquires the paradoxical bistate status). 3rd stage is characterized with the inversion of the ratio free energy/entropy contributions – it changes from the negative to positive, with appearance of the key properties of the biological organization (the ability to concentrate free energy and information, ability for intensified counteraction to external influences, expedient behaviour, continuous self-renovation). On the early Earth such successive transformation of organic matter occurred in changeable conditions of hydrothermal medium. |
