Communication and the development of discursive knowledge are more complex processes than to “consider that communication and self-production are but the two inseparable sides of the bio "coin" --in order to self-produce the living has to communicate with the environment, and in order to communicate the living needs its flexible self-production processes...

Better left for a future exchange...]<o:p></o:p></p><p style='margin-left:.5in'>About the a priori modeling of information --and meaning-- which was the focus of Marcus' presentation, putting together Shannon, Bateson, and Darwin, I am not sure how that scheme would translate into the "real" living stuff. Mostly thinking on the work my team has done on bacterial communication for years, I mentioned days ago three basic points about that: universals, species-specificity, and essential cores. <o:p></o:p></p><p style='margin-left:.5in'>How a plurality of those information universals could be wrapped or articulated around an essential core? That's the toughest point in my opinion. It becomes a matter for freewheeling speculation, badly needed of Schrodinger's disclaimer. Well, let us consider that communication and self-production are but the two inseparable sides of the bio "coin" --in order to self-produce the living has to communicate with the environment, and in order to communicate the living needs its flexible self-production processes... (just to fabricate the meaning!)<o:p></o:p></p><p style='margin-left:.5in'>In bacteria, the side of communication might be seen as implying:<o:p></o:p></p><p style='margin-left:.5in'>--<b>Communication for self-production</b>: detection and introjection/ejection of environmental substances (water, anions, cations, minerals, nutrients, metabolites, waste, and toxics). In bacteria this is crucial. Most of it, apart from the spontaneous membrane permeability, is done by around one hundred different ONE-COMPONENT SYSTEMS (1CS) and a variety of channels and transporters. <o:p></o:p></p><p style='margin-left:.5in'>--<b>Communication with con-specifics</b>: in reproduction (sex exchanges, plasmid exchanges); in social structures (colonies and biofilms); in "differentiation" (sporulation, occasional differentiated types). Around 10-20 TWO-COMPONENT SYSTEMS (2CS) may be in charge, although amply swapping their functions with the previous 1CSs.<o:p></o:p></p><p style='margin-left:.5in'>--<b>Ecosystem communication</b>: cooperation and competition with other species in ecosystems; chemical arm races with fungi, viruses, other bacteria, protists, etc.; symbiosis, cooperation and parasitism with multicellular hosts; pathogenic switching... We may find tools such as 1CS, 2CS, 3CS, special protein kinases, and very complex apparatuses for pathogenesis, predation, and chemical arm races.<o:p></o:p></p><p style='margin-left:.5in'>Not much emphasis needed in that those three items are universals, species specific, and more or less differentiated/entangled within the mentioned communication side of the bio core. <o:p></o:p></p><p style='margin-left:.5in'>Thereafter, thinking about the universals side of self-production, could we terribly simplify our informational view of self-production, as Francis Crick's mandated with h<span class=st>is Central Dogma of molecular biology? Nonetheless it was the first cogent explanation of the flow of genetic information within a biological system. In any case, what we find is different informational architectures --membranes and cytoskeleton rudiments, nucleic acids, processing enzymes-- which are respectively based on identity, complementarity, and supplementarity principles (Shu-Kun Lin). They are playing together the <b>replication, transcription,</b> <b>translation, house-keeping</b>, and <b>degradation</b> functions that apparently integrate the bulk of self-production... </span><o:p></o:p></p><p style='margin-left:.5in'><span class=st>Summing up the obtained items, and just to close the present speculation, we might have found three universals of communication and another five of self-production. Indeed they look very densely entangled within an essential core. At stake is whether they are sufficiently congruent and ontologically robust. Perhaps the most interesting aspect is that herein it becomes relatively easy to upend meaning, value, knowledge-recombination and other members of the conceptual cluster that usually accompanies information.</span><o:p></o:p></p><p style='margin-left:.5in'><span class=st>Thanking in advance for the patience!</span><o:p></o:p></p><p style='margin-left:.5in'><span class=st>--Pedro</span><o:p></o:p></p><pre style='margin-left:.5in'>-- <o:p></o:p></pre><pre style='margin-left:.5in'>-------------------------------------------------<o:p></o:p></pre><pre style='margin-left:.5in'>Pedro C.
