Some of my co-workers study the origin of life, and part of their work focuses on pre-biotic peptide synthesis.

I am convinced that nucleotides appeared well before protein synthesis, and that protein synthesis appears at a mature stage during life's evolution, likely catalyzed by ribozymes... So I don't think that pre-biotic peptide synthesis is relevant for the origin of life!

I am making an effort to study the alternative hypotheses in which life has a proteomic origin. My opinion is still unchanged, but I found this article interesting because at least it proposes a somewhat viable model.

Do you have any opinions about the origin of life?
