Over many years and probably trillions and trillions of chemical reactions, more complex molecules, and more stable molecules, formed.
âThe essence of Metabolism First is that the various complex molecules of life came after the spontaneous formation of very simple molecules. Pathways leading to the complex molecules evolved and their evolution was assisted by the evolution of various catalysts, some of which were biological in nature.â
