Darwinian Daisyworld model from and Watson & Lovelock (1983), Robertson & Robinson (1998) and Lenton & Lovelock (2001).

Units of time are 40 Myr, giving R&R's span of 10 Gyr.

This model offers many opportunities for modification. Maybe the Black and White populations can mutate into each other? The role of q as a measure of segregation of the B and W populations is interesting, and while this model uses purely stigmergic communication between species, direct interaction would also be possible.

This is a very general model of two interacting species which describes a wide variety of different kinds of interaction, for example: cooperation, symbiosis, competition or predation.

Note that in systems biology the word 'species' can mean species of organism, species of chemical or species of cell. Similarly, 'interaction' can mean chemical interaction, genetic interaction or phenotypic interaction. We are talking here about very general kinds of system.

A damped, driven pendulum. The combination of damping and driving provokes a minimal case of chaos. The system is not in itself biological, however its chaotic behaviour arises from competing oscillatory influences - a situation which plays a role in many biological systems.
