GENERAL CONSIDERATIONS - Choose an example - Incremental [Stable --> Stable] - May be hierarchic Number.Number... or Name.Name... --> then Query - Representational [Information <-> Function] - Genetic: Representational, reproductive, von Neumann - Dynamic - Evolutionary Local: Adaptation, Niche --> Niche Global: In origins Information = Function; in single celled forms reproduction, metabosism, locomotion, perception,... are the function of the one cell with different structures... further back in evolution there is only one structure... further forward cells have specialized functions... in origins "chicken and egg" are identical...
