Archived from the original on October 19, They found that the volcano-like experiment had produced the most organic molecules, 22 amino muller, 5 amines and many hydroxylated molecules, which could have been formed by hydroxyl radicals produced by the electrified steam.

More recent results may question these conclusions. Archived from the original on December 13, In a interview, Stanley Miller recollected his lifelong experiments following his original work and stated: Common descent Earliest known life forms Last universal ancestor Protocell Symbiogenesis.

His experiment produced a large amount of adenine, expeeimento molecules of which were formed from 5 molecules of HCN.

One-step reactions among the mixture components can produce hydrogen cyanide HCNformaldehyde CH 2 O[13] [14] and other active intermediate compounds acetylenecyanoacetyleneetc.

Experiment de Miller i Urey

According to the model, drying of the intercalated layered material should provide energy and co-alignment required for peptide bond formation in a ribosome -like fashion, while re-wetting should allow mobilising the newly formed peptides and repopulate the interlayer with new amino acids.


Archived from the original PDF on Peptides formed remained over-protected and shown no evidence of inheritance or metabolism. The group suggested that volcanic island systems became rich in organic molecules in this way, and that the presence of carbonyl sulfide there could have helped these molecules form peptides. Most of the natural amino acids, hydroxyacidspurines, pyrimidines, and sugars have been made in variants of the Miller experiment.

Archived from the original on 3 March As observed in all subsequent experiments, both left-handed L and right-handed D optical isomers were created in a racemic mixture.

Archived from the original on The experiments showed that simple organic compounds of building blocks of proteins and other macromolecules can be formed from gases with the addition of udey.
