Summary
Thermal polycondensation of amino-acids as a possible prebiotic path of chemical evolution of life has been critically examined.
The polymeric materials studied by nmr methods have scarce resemblance to natural peptidic material because β, γ and ε peptide bonds largely predominate over\(\tilde \alpha \)-peptide bonds.
