Which came first: the chicken, the egg, or guanine?

The main goal of the origin of life (OoL) hypothesis is to reconstruct the missing link between the primordial soup and the extant biology. However, the OoL itself is just the initial part of the link representing the bootstrapping operation of Darwinian evolution. The rest of the link is the emergence of the evolution to the present day primary biological system-the ribosome-based translation apparatus. A valid hypothesis must (i) not invoke Darwinian evolution in the bootstrapping and (ii) transform the ab initio life form into the translation apparatus without violating the principle of continuity (i.e., only incremental steps without foresight). Currently, no such hypothesis exists. Here, I discuss the Quadruplex World hypothesis, which fully complies with these requirements and suggests a spontaneous emergence of the ab initio life form. The spontaneity of OoL arises from the physicochemical properties of guanine monomers in a manner of causal determinism: each step of the process (i.e., scaffolding, polymerization, and folding) is caused by the most recent past step such that in the end only the specific 3D architecture forms. The architecture (i) has a length-independent folding pattern; (ii) can play the role of the predecessor of tRNA and single-handedly conduct a primitive form of translation; and (iii) can evolve into the extant translation apparatus without any paradoxes.
