How does the Miller-Uray hypothsis relate to the hypothesis developed by Gunter Wachtershauser?

Answer 1

One of the key ideas advanced by Wächtershäuser is that an early form of metabolism predated genetics. Metabolism here means a cycle of chemical reactions that produce energy in a form that can be harnessed by other processes. The idea is that once a primitive metabolic cycle was established, it began to produce ever more complex compounds. The Miller-Urey experiment (or Urey-Miller experiment) was an experiment that simulated hypothetical conditions present on the early Earth and tested for the occurrence of chemical evolution. Specifically, the experiment tested the hypothesis that conditions on the primitive Earth favored chemical reactions that synthesized organic compounds from inorganic precursors.
