[Fis] Summing up: New Year Lecture

2018-01-22 Thread Pedro C. Marijuan 

Dear FISers,

Going to the extreme, I think this year opening lecture can be 
summarized in three contentious points.


1. That life's physiology is based on the conjunction of a few 
principles: neguentropy, chemiosmosis, and homeostasis-homeorhesis.


2. That communication (cell signaling) is an essential factor in the 
multicellular evolution towards complexity.


3. That epigenetic inheritance and the obligate recursion to the 
unicellular state become the basis of a new evolutionary theory.


I disagree with point 1, as I think some nonliving states could also be 
characterized by those principles (eg, chemical cycles/hypercycles in 
marine vents, and other outcomes derived from "energy flows"); besides, 
some previous "info stuff" has to be in place. Then I completely agree 
with point 2, for signaling is not just another characteristic of the 
cell, it is "the" eukaryotic trait par excellence.  And I am curious on 
how point 3 could be further substantiated... In this respect I 
recommend the two papers that Bill sent to the list a few weeks ago. Do 
we need to postulate the emergence of a form of "self-referential 
cognition" right at the beginning?

Perhaps!

All the best--Pedro

Dear Pedro and Colleagues,

I have been following the thread of comments with great interest, all 
of  which have all been occasioned by John Torday's profound insights 
about the nature of evolutionary development in light of the 
importance of cell-cell signaling and molecular biology.  From the 
comments, it is clear that there is a strong impulse to seek a means 
of integrating the role of symbiogenesis, viruses and mobile elements, 
multilevel selection, niche construction, genomic plasticity into a 
common narrative with an informational perspective at its foundation.
In the spirit of that line of discussion, I am offering two links 
that discuss evolution as an biologic information management system. 
Some of this work shares direct commonality with John's, since he and 
I are frequent collaborators.


http://www.mdpi.com/2079-7737/5/2/21/htm

https://www.sciencedirect.com/science/article/pii/S007961071730233X

Both of these articles can be considered as complementary to Pedro's 
very fine article, 'How prokaryotes ‘encode’ their environment: 
Systemic tools for organizing the information flow', which is in 
BioSystems.


I am grateful to John for inviting me to participate in the forum and 
to Pedro for encouraging me to share these manuscripts.


Best regards,
Bill
