Possible mechanisms for the origin of life

Neither Evolution nor physical necessity are a driving force prior dna replication :

Without code there can be no self-replication. Without self-replication you can’t have reproduction. Without reproduction you can’t have evolution or natural selection.

Heredity is guaranteed by faithful DNA replication whereas evolution depends upon errors accompanying DNA replication.  ( Furusawa, 1998 ) We hypothesize that the origin of life, that is, the origin of the first cell, cannot be explained by natural selection among self-replicating molecules, as is done by the RNA-world hypothesis. ( Vaneechoutte M )
The origin of the first cell, cannot be explained by natural selection (Ann N Y Acad, 2000) DNA replication had therefore to be previously, before life began, fully setup , working, and fully operating, in order for evolution to act upon the resulting mutations. That means, evolution was not a driving force and acting for the emergence and origin of the first living organisms. The only remaining possible mechanisms are chemical reactions acting upon unregulated, aleatorial events ( luck,chance), or

physical necessity.  ( where chemical reactions are  forced into taking a certain course of action. )  

Laurent Boiteau Prebiotic Chemistry: From Simple Amphiphiles to Protocell Models, page 3:
Spontaneous self-assembly occurs when certain compounds associate through noncovalent hydrogen bonds, electrostatic forces, and nonpolar interactions that stabilize orderly arrangements of small and large molecules.  The argument that chemical reactions in a primordial soup would not act upon pure chance, and that  chemistry is not a matter of "random chance and coincidence , finds its refutation by the fact that the information stored in DNA is not constrained by chemistry. Yockey shows that the rules of any communication system are not derivable from the laws of physics.  He continues : “there is nothing in the physicochemical world that remotely resembles reactions being determined by a sequence and codes between sequences.” In other words, nothing in nonliving physics or chemistry obeys symbolic instructions.

The Genetic Code
DNA contains a true code. Being a true code means that the code is free and unconstrained; any of the four bases can be placed in any of the positions in the sequence of bases. Their sequence is not determined by the chemical bonding. There are hydrogen bonds between the base pairs and each base is bonded to the sugar phosphate backbone, but there are no bonds along the longitudional axis of DNA. The bases occur in the complementary base pairs A-T and G-C, but along the sequence on one side the bases can occur in any order, like the letters of a language used to compose words and sentences. Since nucleotides can be arranged freely into any informational sequence, physical necessity could not be a driving mechanism.

If design, or physical necessity is discarded, the only remaining possible mechanism for the origin of life is chance/luck.

Dynamic kinetic stability (DKS) 1

Recently, one of us (A.P.) has described a new stability kind in nature, seemingly overlooked in modern scientific thought, which we have termed dynamic kinetic stability (DKS) . That stability kind, applicable solely to persistent replicating systems, whether chemical or biological, derives directly from the powerful kinetic character and the inherent unsustainability of the replication process. However, for the replication reaction to be kinetically unsustainable, the reverse reaction, in which the replicating system reverts back to its component building blocks, must be very slow when compared with the forward reaction; the replication reaction must be effectively irreversible. That condition, in turn, means the system must be maintained in a far-from-equilibrium state , and that continuing requirement is satisfied through the replicating system being open and continually fed activated component building blocks. Note that the above description is consistent with Prigogine's non-equilibrium thermodynamic approach, which stipulates that self-organized behaviour is associated with irreversible processes within the nonlinear regime . From the above, it follows that the DKS term would not be applicable to an equilibrium mixture of some oligomeric replicating entity together with its interconverting component building blocks.
