(Why does life originate and exist now? It is the main question!
How does life originate? It is the second question!)
The transition between the animate and inanimate matter is a slow. It was predestined by the action of “thermodynamic principle of the substance stability” ( http://www.mdpi.org/ijms/papers/i7030098.pdf ) which describes the forward and backward linkages at the transmission of information between structural hierarchies during the chemical and biological evolution. http://gladyshevevolution.wordpress.com/article/thermodynamic–theory–of–evolution–of-169m15f5ytneq-3/
See: Thermodynamics and the emergence of life.
The phenomena of life can be explained on the basis of quasi-equilibrium hierarchical thermodynamics of dynamic systems which stands at the solid foundation of thermodynamics of JW Gibbs. Theory can be constructed without using the concept of dissipative structures of I. Prigogine and his ideas about negentropy.
From the point of view of thermodynamics, the phenomenon of life is defined as: “Life is the process of existence of constantly renewed polyhierarchical structures during cycles of transformation of labile chemical substances in the presence of liquid water on the planet.”
