Clearly the verdict has to be the Scots one of "not proven," and it is only fair to say that Stanley Miller, a pioneer of prebiological chemistry, believes that the terrestrial molecule choices were entirely random, not driven by any fundamental physics.
Instead, he conflates the problems of generating information via biological and prebiological natural selection, and in so doing, fails to grapple with the critical difficulties in origin-of-life research that partly underscore the cogency of my argument.
One of these, uracil, tends to react with formaldehyde, a molecule that scientists think existed abundantly on prebiological Earth.
In the prebiological world, as a few molecules became predominant, they would have influenced other molecules with which they interacted.
In subsequent years, an interdisciplinary field of theoretical and experimental biochemistry, known as origin-of-life research, has itself evolved, driven primarily by biochemists eager to understand the fundamental, chemical mechanisms of prebiological molecules.
