Simulation Models to Play With

A Model of Symbiosis/Cooperation

The Emergence of Symbiotic Groups Resulting From Skill-Differentiation and Tags (NetLogo version).  This model is describe in:

Edmonds, B. (2006) The Emergence of Symbiotic Groups Resulting From Skill-Differentiation and Tags. Journal of Artificial Societies and Social Simulation, 9(1). (http://jasss.soc.surrey.ac.uk/9/1/10.html).

A Model of the Evolution of Diveristy and Lineages under Disasterous Conditions

This is an abstract model to explore the different evolutionary trajectories that might occur in the presence of severe disasters. The model forces the individuals to compromise between getting food and avoiding the disasters, since these have a tendancy to occur in the same places. The geneone and environment is deliberately sufficiently complex to allow an open-ended evolutionary debvelopment of genes. Species here are those with the same geneone.

A Model of Speciation with Sex and Space

This model is an a reimplementation of the model described in:
