We suppose that such approach, although is illustrative, but distracts from the circumstance that any living system is to be considered an integrated structural-functional complex. The maintenance of existence of this system is being impossible without the processes aimed at preserving this complex. This leads to the concept of cooperons - the self-preserving dynamic structures existing only as a result of specifically organized cooperative various processes. From this point of view, all living systems are cooperons of different hierarchy levels. Some other systems, for example the symbiotic ones, also are cooperons. Within a framework of this concept, it is possible to discuss the functioning of living systems of different types of organization in a new context.

International Society of Limnologists is holding meetings since 1922. Proceedings of meetings were used to find out principal stages of history of this science (rapid and calm periods). The simulation model of limnology development was built on the basis of such analysis. Every scientist can generate with some probability new ideas and elaborate existing ones. The model includes as parameters the properties of scientists and surroundings (age, experience, level of contacts between scientists, etc). After the model was tuned experiments with different parameters was made. They demonstrate level of contacts influences most strongly on rapidity of the science development.

The majority of the theories are founded on different hypotheses which describe origin of primary primitive organisms by some non-biological ways, for example, by self-organization of non-living substances. The origin of the biosphere (Gaia) is considered within a framework of such approaches as one of consequences of the origin and subsequent expansion of different species. At that the biosphere is described as simple sum of all organisms but not as united functional system. On the other hand, it is known that any terrestrial organisms are not able to survive and to reproduce outside the biosphere as well as without interactions with other organisms (this is possible sometimes but during only restricted time). Therefore the hypothesis about simultaneous origin of organisms and biosphere is looked quite probable. But such approach leads to several assumptions, in particular about inclusion of earliest forms of pre-life into planetary circulations.

The second section concerns physical, cybernetic and anticipatory aspects of the life evolution. The different approaches to the problems of biological evolution are discussed in the third section of the article. The attention is focused on the biosphere evolution, which is regarded as the control factor for the biological evolution. In the fourth section the problem of the origin of life is discussed. One of the conclusions is the mechanism of panspermic hypothesis could work only if the conditions on planet has specific features which can be described within a framework of so called the embryosphere hypothesis.

The first presented program simulates the macroevolution of Chordata animals inside the space with different environments. Darwinian regulations of mutating and competition were set at the initial program version, but the model shows this is not enough to explain known particularities of biological evolution. Another model demonstrates that the evolutionary stability of species is a consequence of prohibitions on some types of evolutionary modifications. Our new simulation uses alike principles as the above but this model concerns the evolution of the human ethno-populations. The central feature, which distinguishes the man evolution from other cases, is that the interaction between man-populations and environment is controlled by human culture.

The physical evolution which is the increasing of energyflow passing through the biosphere plays main role before the origin of man.This increasing is a consequence of perfection of photosynthetic possibilities of plant communities and of all biosphere system. It is shown that ihe life uses optimal evolutionary ways for physical evolution and, hence, optimal behavioural reactions in every moment of evolutionary time. The ultra-rate evolution of the modern biosphere is connected with a human activity which is not possible without informational exchange between individuals. This exchange leads to training of individuals to new ways of survival and, therefore,to modifications of ecological niches of humansub-populations and ecological licences of the biosphere. The mechanisms of both producing of new information in human community and dissemination of this information are considered. One of the important deductions of the such approach is the rates of these processes depend strongly on the parameter which is named as a priori values of information. The evolutionary modifications of the modern biosphere are interconnected not only with slow physical evolution but with very fast cognitive anticipatory evolution.

At present, in spite of the brilliant successes in cybernetics, the investigations of the auto-regulation for living systems in context of their development or/and evolution are hampered by essential theoretical and methodological difficulties. In this paper we present several simple approaches which can give some basis to elaborate in the future new quantitative models in above fields. The first approach concerns the management of energy flows, the second one introduces the concept of the so called "the Life Demon". The Demon is specific non-material object which is factually an algorithm and which can propagate by the alike way as it does virus. The third approach results in the simple type of electronic model which describes some features of behaviour for the objects of the first and of the second approaches, in particular, auto-regulation activity, searching activity, anticipatory behavior. We suppose that these approaches can be joined and perfected in the future with use of the balance kinetic models of auto-regulations for the cases of quasi-isolated ecosystems and for biosphere.

Out of several general statements and mechanisms discussed above, we would like to specially note the following : the paradigm of autocanalisation, an ecocentric concept of macroevolution, a license-ecosystem approach, the hypothesis of embryosphere and, at last, a physico-ecological model of biospheric evolution. Ecological crises within the framework of our approaches are just ordinary evolutionary events of biospheric evolution autocanalised by the biosphere itself under the inconstant exogenous conditions on the planet.
