[Fis] life cycles

 Dear FIS colleagues,

The comments by Stan and Koichiro are intriguing. Particularly if we 
swap the term energy for information (communication exchanges). What 
kind of communication relationship develops between the living and the 
environment along the advancement of the life cycle? How does this 
relate to complexity? Maybe the endless repetition of cycles, when an 
inner coding is included, can take both directions: the increase of 
complexity and also the decrease. Stephen Gould made good arguments 
about that: organismic complexity may actually decrease in certain 
environments, as dramatically happens for instance in Mycobacteria 
Pneumonia, one of the simplest living (autonomous) organisms. The life 
cycle imposes its adaptive rules to which complexity should passively 
follow... The prokaryotic biomass still predominates and rules the 
geocycles of the Planet.

Steven and Jerry have made another series of interesting comments, to 
which I would like to ad. The discussion of locality is a preliminary 
aspect, as in my view the nitty-gritty occurs afterwards. What happens 
along the relatively delocalized "propagation of influence" of the 
received signal? The ample self-modification & self-reconfiguration that 
follows is the essential topic: all the other attributes & concepts 
associated to information both as communication and as self-production 
would hang from the events which surround this flow of influence. 
Nothing like that web of physical self-modification occurs in the 
artificial computing: the hardware is very, very hard. Adaptive 
self-reconfiguration could be a more or less adequate technicality, but 
actually it is the production of palpable "meaning". It is the 
intertwining of communication and self-production, endlessly in action, 
repeating the cycle of life --a back of the envelope estimation would 
tell that more than 3 x 10 exp 14 times has been running the roulette of 
the life cycle in each one of the existing lines of descent...

Best wishes to all
