Hello! I'm reading a book titled Abiogenesis: How Life Began. The Origins and Search for Life. I was hoping someone would be able to explain the following. Its based on the theory that life emerged around hydrothermal vents: "The real entropic output of life then is not the complex organic molecules that constitute life and enable the processing, but those waste products closer to equilibrium than the reactants, such as methane, acetate and certain sulfides and oxides as well as the recalcitrant stable organic molecules such as the hydrocarbons that tend to be interred within the sedimentary piles." (my own emphasis). This makes no sense to me. Particularly the bolded part. Any help at all is appreciated. Thanks in advance.
