A famous experiment in 1953 showed that amino acids, the building blocks of proteins, could have formed spontaneously under the atmospheric conditions of early Earth. However, just because molecules could form doesn’t mean that the process was likely. Now, researchers reporting in ACS Central Science have demonstrated that energetically feasible interactions between just two small molecules—hydrogen cyanide and water—could give rise to most of the important precursors of RNA and proteins.
