Life on Earth is shaped by the environmental conditions of the planet. Therefore, it is probable that life started as a subcycle of geochemical cycles on early Earth. I will talk about the possible relationships between clay weathering and K+/Na+ gradients, evaporation of saline lakes and condensation reactions, in addition to the Krebs cycle and conductive minerals. I suggest that the first compartments were small rock cavities that hosted simple chemical networks formed by small organic...
