Etiology of Potentially Primordial Biomolecular Structures: From Vitamin B 12 to the Nucleic Acids and an Inquiry into the Chemistry of Life’s Origin: A Retrospective

“We’ll never be able to know” is a truism that leads to resignation with respect to any experimental effort to search for the chemistry of life’s origin. But such resignation runs radically counter to the challenge imposed upon chemistry as a natural science. Notwithstanding the prognosis according to which the shortest path to understanding the metamorphosis of the chemical into the biological is by way of experimental modeling of “artificial chemical life”, the scientific search for the route nature adopted in creating the life we know will arguably never truly end. It is, after all, part of the search for our own origin.
