According to the model, drying of the intercalated layered material should provide energy and co-alignment required for peptide bond formation in a ribosome-like fashion, while re-wetting should allow mobilising the newly formed peptides and repopulate the interlayer with new amino acids. In December 2017 a theoretical model developed by Erastova and collaborators suggested that peptides could form at the interlayers of layered double hydroxides such as green rust in early earth conditions. Peptides formed remained over-protected and shown no evidence of inheritance or metabolism. Since John Desmond Bernal's suggestion that clay surfaces could have played a role in abiogenesis, scientific efforts have been dedicated to investigating clay-mediated peptide bond formation, with limited success. The main problem of theories based around amino acids is the difficulty in obtaining spontaneous formation of peptides. ![]()
