So a âmetabolism secondâ mechanism seems plausible to me. The first organic cells had no nucleic acid at all. They didnât have DNA or RNA. However, the mineral surfaces with the scaffold defects made nucleic acids stable. So the first RNA formed on a crystal surface that had already evolved to adsorb organic molecules. Here are a few links on some models for mineral scaffolding. The idea that life began as clay crystals is 50 years old
