The Origin of Biosphere

The problem of origin of the life is broadly being discussed during very long time. 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.
