Référence? Quelle expérience a prouvé cela?
De totue façon, il semble que ce soit une nouvelle affirmation parfaitement fausse, si on regarde les choses correctement:
La vieille lune à Julien ne dit absolument pas que l'abiogenèse est impossible mais qu'elle n'est pas encore explicable. De plus, j'ai déjà cité une référence qui montre qu'il existe plusieurs théories expliquant l'abiogenèse (La Recherche, n°336, 2000, dossier sur "les origines de la vie"*). Ce qui reste à trouver c'est la bonne, celle qui explique le plus de faits.
Si Julien ne cherche pas à lire ce genre de littérature, c'est bien par "mauvaise foi, [...] fanatisme et [...] désir de ne pas voir la réalité en face", en plus d'une allergie certaine à la réalité scientifique.

"Advances in directed evolution and membrane biophysics make the synthesis of simple living cells, if not yet foreseeable reality, an imaginable goal. Overcoming the many scientific challenges along the way will deepen our understanding of the essence of cellular life and its origin on Earth"
Rode BM (1999) Peptides and the origin of life. Peptides 20(6):773-86
"Considering the state-of-the-art views of the geochemical conditions of the primitive earth, it seems most likely that peptides were produced ahead of all other oligomer precursors of biomolecules. Among all the reactions proposed so far for the formation of peptides under primordial earth conditions, the salt-induced peptide formation reaction in connection with adsorption processes on clay minerals would appear to be the simplest and most universal mechanism known to date. The properties of this reaction greatly favor the formation of biologically relevant peptides within a wide variation of environmental conditions such as temperature, pH, and the presence of inorganic compounds. The reaction-inherent preferences of certain peptide linkages make the argument of 'statistical impossibility' of the evolutionary formation of the 'right' peptides and proteins rather insignificant. indeed, the fact that these sequences are reflected in the preferential sequences of membrane proteins of archaebacteria and prokaryonta distinctly indicates the relevance of this reaction for chemical peptide evolution. On the basis of these results and the recent findings of self-replicating peptides, some ideas have been developed as to the first steps leading to life on earth."
