Early emergence of protein precursors.
For the emergence of protein precursors essential to primitive cells three prerequisites must have been fulfilled: selective aqueous polymerization of proteinaceous amino acids from a complex mixture of small organic compounds, selection of homochiral amino acid sequences and catalytic activity with respect, more precisely, to information transfer processes.
