Dear Gavin et.FIS, Information processing is omnipresent in biology. Alan Turing's reaction-diffusion model of morphogenesis is certainly well-known.
Here are a few more examples implying information processing within biological systems: 1. Vrancisco Varela's self-reference calculus: http://www.slideshare.net/PriMate_PaTagOn/francisco-varela-a-calculus-for-selfreference-1707403 http://homepages.math.uic.edu/~kauffman/VarelaCSR.pdf and its implications: http://homepages.math.uic.edu/~kauffman/NetworkSynthesis.pdf http://onlinelibrary.wiley.com/doi/10.1002/sres.1105/abstract;jsessionid=8CC55298874EE9F1A9A0D886491099EA.d04t04?systemMessage You could find more about it on Google 2. Robert Rosen's Anticipatory Systems and category theoretical studies on Life Itself (cf.. Amazon) and Aloisius Louie's continuation of that path with "More than Life Itself". 3. Andree Ehresmann's dynamic CT based Memory Evolutive Systems (MES) (cf. Amazon) There are still many aspects of living systems that were not captured "at the roots" of the phenomena by mathematics and computation to this moment, despite several attempts for over 60 years. This is a huge field to be explored yet. But the complexity of the biological phenomena does not imply the automatic application of standard physicalistic approaches.I am not the first who claims that an H2O molecule in an the cat Tom is different form the one in the mouse Jerry, and then from the one in the pool in the garden. This is e.g. one of the issues where physics as it is cannot help further (individuality). Using and refining the tools we have in one field, does not imply a dogmatic denial of the necessity to invent new tools for another field that could be more effective there. Mathematics and physics as such cannot explain biology to the extent we need to know. They need to be developed to include the peculiarities of the phenomena at hand. I will stop here for now.
