Abstract. The
ecosphere is a natural construction, the development of which fundamentally
differs from the way the other planets in our solar system evolved. Life
emerged consequently to the connection between non-living factors and
macromolecules complex carbon-based compounds. Living beings had the capacity
of creating a new type of informational pattern, which soon assumed the
coordination of major processes at the planetary level, and the non-living
components the atmosphere, the hydrosphere and the lithosphere were
substantially modified by the biosphere. Our approach regarding thr evolution
of life is an ecological one; emphasis is put on the interrelations between the
living and the non-living worlds: the emergence of metabolism, interspecific
relations, the use of multiple energy sources; the emergence of life generated
biogeochemical cycles and evolutionary processes characterized by self-control,
self-organization and self-improvement. A special role was played by the
transition from the use of chemical energy to the use of light energy, with the
release of oxygen, which, owing to oxidative reactions, became the main element
in the global development of most energetic processes. Life progressed from self-reproducing organic macromolecules
to protoorganisms, then single-celled organisms (prokaryotes) and finally
eukaryotic organisms emerged. In time, they populated all environments: the
marine, the brackish, the freshwater, the terrestrial and the underground one.
Living beings created two planetary covers: the biosphere and the pedosphere.
The interconnection of the biosphere with the non-living covers (the
atmosphere, the hydrosphere, the lithosphere and the pedosphere) resulted in
the emergence of the ecosphere.
