Genomic Completeness2. Cellular Uncertainty3. Stochasticity of Cell Origins and Fates 11. 1. Genomic Completeness2. Cellular Uncertainty3. Stochasticity of Cell Origins and Fates 12. the internal and the external co-determine the cell.Richard Lewontin, 2000 13. 2nd Principle:Cellular UncertaintyAny attempt to observe a cell alters the state of that cell at the time of characterization and potentially alters the likelihood of subsequent differentiation events. 14. 2nd Principle:Cellular UncertaintyAny attempt to observe a cell alters the state of that cell at the time of characterization and potentially alters the likelihood of subsequent differentiation events.? 15. Meanwhile,back at the plasticity debates 16. Controversy!!! 17. trivial...vs.ROBUST!!! 18. Conversations with Jane ProphetNew Media Artist and Professor, Interdisciplinary StudiesUniversity of Westminster, London UKSciArt Award, Wellcome Trust 2002 19. Date: 9th May 2002Location: Neils office, New YorkJane says: Ideas about pathways are interesting. A lot of people who are involved in digital biology are interested in things like swarming people and socalled soup organism behaviour. And one of the useful models to take forward is about ant colonies 20. Complex Adaptive Systems:1,21Lewin R, Complexity: Life at the Edge of Chaos. 2nd ed. Chicago IL: University of Chicago Press; 2002.2Johnson S, Emergence. New York NY: Scribner; 2001. 21. Complex Adaptive Systems: Interacting individuals that, if they fulfill 4 criteria,organize themselves from the bottom up,into larger structures 22.

Complex Adaptive Systems: Interacting individuals that,if they fulfill 4 criteria,organize themselves from the bottom up,into larger structureswhich appear planned from the top, downward,BUT ARE NOT! These structures are referred to asemergent self-organization and are ADAPTIVE. 25.

Communities BodiesCellsBiomoleculesThe validity of cell doctrine depends on the scale atwhich the body is observed 49. Communities BodiesCellsBiomoleculesThe validity of cell doctrine depends on the scale atwhich the body is observed. To limit ourselves to theperspective of this model may mean that explications ofsome bodily phenomena remain outside the capacity ofmodern biology 50.

Communities BodiesCellsBiomoleculesThe validity of cell doctrine depends on the scale atwhich the body is observed. To limit ourselves to theperspective of this model may mean that explications ofsome bodily phenomena remain outside the capacity ofmodern biology. It is perhaps time to dethrone thedoctrine of the cell, to allow alternative models of thebody for study and exploitation in this new, postmodernera of biological investigation. 52. What kind of models? 53. for example,2 models from Ancient Greece:Is the body made ofindivisible subunits or an endlessly divisible fluid 54. Models of the body are perspective/technique dependent Look at it this way (cell membranes): the body is made of cellsLook at it that way (organelles): the body is an endlessly divisible fluid 55.

All living systems are cognitive systems.Conciousness Sense Making Sentience 91. Theyve found that some of the key molecularbuilding blocks of neurons predate even the firstmulticellular organisms. By looking down the treeof life, they are concluding that assembling thesecomponents into a cell a modern neuroscientistwould recognize as a neuron probably happenedvery early in animal evolution, more than 600million years ago. Most scientists agree thatcircuits of interconnected neurons probably arosesoon thereafter, first as diffuse webs and later as acentralized brain and nerves. G.

Conclusion:While one may argue that sense makingand therefore some form of conciousness islimited, extending downward in scale onlyto the smallest, autopoietic elements of life namely the cell a complexity analysis ofthe universe (as a unified, self-organizingand emergent system) reveals that theuniverse is sentient throughout; thatsentience is inherent and universal in thestructures of existence. 101.
