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 an example of how to model populations involving recombination and mutation. The Hardy-Weinberg Law gives us the effects of recombination, and mutation is represented by a flux between alleles.
Possible extensions: Build in differential fitness of the three genotypes, have them differentially interact with an external environment, or have them interact with each other. (There is already an interaction term in the three 'die' flows.)
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.
