Abstract:
The Earth’s biosphere appeared in a self-organization process along with the appearance of the Solar System. It is shown, based on the methods of self-organization examination and existing knowledge, that major stages of the chemical evolution in the early development of the biosphere include the “cold prehistory of life” in dense molecular nebulae, “pre-planetary chemocoenosis,” “RNA-world” in a circumsolar nebula, and primary biocoenoses of protocells (life) on the planetary bodies. Estimates for carbon in the primordial biosphere on the young Earth’s surface give 2.4 × 1019 kg. The decay of the primordial Earth’s biomass and biogeochemical cycles in 2.5 Myr led to the “planet of bacteria” with 2.0 × 1015 kg of biota in the Proterozoic (at the time of an oxygenated atmosphere). The main parameters (pressure, temperature, and state of catalytic solid phase) are estimated for these stages of the early evolution of life. It is shown that the abiogenic synthesis of the primordial matter was preformed in the Solar System on a grand scale with practically every atom in nanoparticles-catalysts participating. Selection among catalytically active nanoparticles worked towards the ability to synthesize high molecular compounds in a protoplanetary disk. Autocatalysts participated in the preplanetary chemical evolution, beginning from such simple substances as ethylene or glycolaldehyde. Primary synthesis of autocatalysts depended on external sources of energy, e.g., on ultraviolet radiation.
