Biospheric Energization and Origin of Life : Çanakkale “ABC” Model

A model about the origin of life we refer to as “Molecular ABC Model” developed by Çanakkale Astrobiology Group (ÇAG) between 2005-2008, will be reviewed. Proposed model is based on an periodic re-energization process following the day-night illumination cycles of the early Earth. This cyclic energization also allows an auto-catalitic fine tuning, so that, suitable early atmospheric and climatic conditions makes it possible to evolve, from very simple beginnings, into a highly complex and exponentially responsive biosphere. The net growth factor of, so called, “the chemical (organic) potential energy” of the biosphere is very small but continuous since its very beginnings, accumulating its present-day value of biospheric mass, dead and alive. Although net growth factor is very small, it is stable and continious Auto-catalitic processes involved give a fractal character to its development, allowing an observable repeatability. This property also allows the observability of some of the cyclic properties, openning a window of opportunity for the interpretation of possible signs of life-like processes, in the atmospheres of exoplanets.
