ClaimThe Origin and Evolution of Organizational

StructuresCan be analytically explained in terms of a theory

of autocatalytic networks.

Classes of Networks(1) Social Networks: cooperation between

individuals in a community

(2) Economic Networks: transformation and production of economic commodities

(3) Linguistic Networks: production and generation of symbols

Autocatalytic NetworksChemical Reaction Networks

Biochemical Examples

1) Glycolysis: 2 ATP

2) Oxidative Phosphorylation 36 ATP

Product C catalyses ist own synthesis from precursors A and B

Problem

To what extent is the conceptual

framework of autocatalytic networks

an appropriate model for the analytic

study of the origin and evolution of

socio-economic networks?

Origin and Evolution in Three Classes of Networks

(1) Metabolic Networks: Energy production

(2) Social Networks: Evolution of cooperation

(3) Demographic Networks: Evolution of life

Thermodynamic EntropyMeasure of Complexity in Material Aggregates

Solid: low entropy

WkS logW = number of ways that the molecules of a system can be arranged to achieve the same total energy

Gas: high entropy

Second Law of Thermodynamics:

Thermodynamic entropy increases

Organismic Evolution(1) Variation: individuals within a species vary in

terms of their physiology and behavior

(2) Heredity: there exists a positive correlation between the behavioral and physiological traits of parents and their offspring

(3) Selection: individuals differ in their capacity to appropriate resources from the external environment and to convert their resources into offspring

Prerequisites for an Analytical Model of Network Evolution

(1) A mathematical description of network complexity

(2) A formal description of the network-environment interaction

(3) An analytic description of natural selection

(4) A description of the rules of inheritance

EntropyryEvolutionaWkS logW = number of distinct pathways of energy flow in the network

Evolution of Demographic NetworksEvolutionary Changes in Network Complexity

Variation: Changes in the topology and interaction intensity of the network – changes in life history

Selection: Competition between variant and ancestral network for the resources

X = ancestral typeX* = variant type

Page 17: Emergence of Organization and Markets Lloyd Demetrius June 2014

Principles of Demographic EvolutionThe outcome of selection is predicted by evolutionary entropy and is contingent on the external resource constraints:

(I) Resources constant in abundance anddiverse in compositionEvolutionary entropy increases (selection for iteroparity)

(II) Resources variable in abundance,singular in compositionEvolutionary entropy decreases (selection for semelparity)
