This PDF looks like what you're talking about...
Now I'm off to find more research on maxicircles (stored genetic information) and minicircles (contextual editors!)
Here are some of the articles I found thanks to you!!!
The Physics and Evolution of Symbols and Codes:Reflections on the Work of Howard Pattee There are many links on the page with wonderful detail, but the heart of the discussion is summarized by Howard H. Pattee
Von Neumann was the first to propose explicitly why this "threshold" of complexity requires description-based reproduction (taken for granted by biologists), but his argument was focused on the logical, not the physical requirements. He did not discuss the organizational requirements that would allow normal physical molecules to function as descriptions, nor was he clear about his logical distinction between "active" physical dynamics and "quiescent" symbolic descriptions. He did not mention the origin problem except to say it was "a miracle of the first magnitude."
Even if we still do not have a clear picture of the origin of life, the significance of this fundamental distinction between descriptions and constructions, that is, between semiotic processes (rules, codes, languages, information, control) and physical systems (laws, dynamics, energy, forces, matter) reaches to all levels of evolution. This is an essential distinction from the earliest genetic control of the synthesis of proteins, to the codes and languages of the brain, to the distinction between the mind and the brain (the knower and the known, the epistemic cut), and even to physical theory itself that requires a clear distinction between universal physical laws and the local semiotic process of measurement - an area in which there is still no consensus. This distinction between laws and semiosis, as well as how they are related, needs to be made more clearly at all levels if we are to fully understand evolution, physical laws, and the languages of the brain.
In biology, the basic physics and chemistry of elementary life processes as they exist on earth is well-developed. However, our knowledge of the semiotic controls and interactions within and between organisms and in some cases even in single cells is far from complete. In evolution theory it is still not clear that blind variation in a virtually infinite semiotic search space is adequate to explain so many successful species.
