Information and orderliness of living systems

We point out that the quantitative gap between the level of orderliness inherent to living systems and that of open dynamic systems of physical nature 'self-organized' at the expense of external energy fluxes reaches twenty four orders of magnitude. The environmental fluxes of free energy being virtually disordered as compared to living systems, the orderliness of life cannot be maintained by any physical process. To counteract the spontaneous decay of the highly ordered state of life, the living matter must be divided into a sufficiently large number of equivalent objects (individuals), among which a competitive interaction is switched on. As soon as the level of orderliness of any given object diminishes below the sensitivity of competitive interaction, such an object loses competitiveness and is replaced by a copy of a normal object retaining the initial high level of order. Such a mechanism of maintenance of order is unique to living matter and differentiates it from the inanimate world.

We also show that the biotic regulation mechanism cannot be replaced by technology, as far as the information processing capacity of the civilisation is twenty orders of magnitude lower than that used by the natural biota for environmental control.
