  • Expecting to find it in stereochemical explanations is a materialist fantasy.

    Consensus: the "refuge of scoundrels"

  • The degenerate code could well be a product of such selection, but: a) there’s at least two other competing families of hypotheses for its origin, namely stereochemical and biosynthetic; and b) that code went to fixation a couple billion years ago in most organisms, so I don’t see that it could provide much evidence for neutrality selection in modern organisms.

  • Thus, we can discern that the genetic code as we understand it today likely evolved in several steps – a stereochemical era wherein a core set of triplet-amino acid correspondences was first established, followed by subsequent expansion of the assignments of other triplets and recruitment of other amino acids (typified by gutamine and leucine) via other mechanisms.

  • On that score you cite a study showing stereochemical affinity.

    Are Stereochemical Explanations Causally Sufficient?

  • This stereochemical concept rests on the original suggestion by van't Hoff of the tetrahedral arrangement of the four valences of the carbon atom (see Section 2), and most organic molecules exist in two or more stable conformations.

  • The bigger issue of the codes's origin is not explained by affinity between aa's and anticodons even if we presume a viable soup and stereochemical explanations for all 20.

    Are Stereochemical Explanations Causally Sufficient?

  • You and others are pointing to Meyer's contention that there is no basis in physics and chemistry alone sufficient to generate the outcome of a genetic code as refuted by stereochemical explanations grounded in Yarus and other studies.

    Are Stereochemical Explanations Causally Sufficient?

  • Art then cites studies showing stereochemical reasons detailing the affinity existing between some amino acids and their anticodons.
