Why our origins may lie in the Hadean era, 4 billion years ago
From a thermodynamic point of view, the likelihood of generating by chance a plausibly prebiotic polymer – such as a peptide from simple ingredients like amino acids – looks extremely slim. not only are such routes to life chemically specific, they also struggle to find anything like a favourable equilibrium state. However, why should the origin of life have been an equilibrium process? In all probability it wasn’t.
