The chemical evolution of biomolecules was clearly affected by the overall extreme environmental conditions found on Early Earth.
![Effect of temperature on the peptide aggregation process. Left: side view of (ODAP—STEP) bilayer systems with peptides at 0 ns (a) and 500 ns at 353 K (b), 338 K (c), and 323 K (d); KSPFPFAA peptides are shown in mauve, while ODAP and STEP are in gray and green, respectively. Right: number of the clusters as a function of time formed during the 500 ns MD simulation with cutoff 0.6 nm at 353 K (e) (previously reported by the authors in Ref.
