More than one researcher is currently proposing that the notion of information become an important element for defining living systems as well as for explaining conditions that make their origins possible. During the pre-biotic era, the type of compounds encountered would mainly have been very simple in nature and might have been immersed in the natural dynamic of the physical world and in processes of self-organization. It is furthermore quite possible that they formed a relationship between and among certain types (...) of processes that here we are specifically proposing as central for the emergence of cell organization. Consequently, an important initial step towards constructing a theory of biological information is to ask ourselves the question: how do biological systems process information? In this way, we will be contributing to the proposals of this paper where we seek to identify general principles that govern biological computing and that deal with biosemiotic approaches as they are defended in naturalistic normative terms.

Open peer commentary on the article “Info-computational Constructivism and Cognition” by Gordana Dodig-Crnkovic. Upshot: Info-computational constructivism calls attention to some of the open questions about the origins of information and computation in the living realm. It remains unclear whether both were developed and shaped by evolution by natural selection or if they appeared in living systems independently of it. If the former, it is possible to sketch a scenario with a certain degree of reasonableness and postulate some of the conditions (...) that triggered the emergence of these biological properties.

In this paper, we present an argument showing why the general properties of a self-organizing system (e.g. being far from equilibrium) may be too weak to characterize biological and proto-biological systems. The special character of biological systems, tell us that its distinctive capacities could have been developed in pre-biotic times. In other words, the basic properties of life would be better comprehended if we think that they were much more likely early in time. We developed a conceptual proposal on the (...) origins of pre-biotic world, a kind of protocellular system which is made up of simple molecular compounds interconnecting three different types of processes. The interrelation of these processes characterizes the “Informational Dynamical System” (our conceptualprotocell proposal) as an autonomous dynamical system that can maintain by itself in far from equilibrium state, as opposed to those that depend on external causes. Consequently it follows that, in the dawn of pre-biotic world, there was no DNA or RNA or proteins to begin with. As well, our proposal implies the separation of biological evolution from the kind of open-ended evolution that gave rise to first breed of animate matter. (shrink)

Lately there has been a growing interest in evolutionary studies concerning how the regularities and patterns found in the living cell could have emerged spontaneously by way of self-assembly and self-organization. It is reasonable to postulate that the chemical compounds found in the primitive Earth would have mostly been very simple in nature, and would have been immersed in the natural dynamics of the physical world, some of which would have involved self-organization. It seems likely that some molecular processes self-organized (...) spontaneously into a hierarchy of complex behaviours. Our conceptual search herein reaches back to the time when prebiotic phenomena began to take shape. This was before the origin of life, so in this paper we hope to shed new light on some of the theoretical issues that surround the ways in which cellular organization might have evolved without the aid of replicated information.
