title=Spatio-temporal chaos|
doc=The initial configuration is symmetric and this symmetry is preserved for some time but then breaks down and settles in spatio-temporal chaos. In the absence of spatial extension, the population would not be able to persist. Fluctuations of increasing amplitude would drive the population to extinction.

The parameters are <math>r=2.34</math>, <math>N=8</math>, <math>c=1</math>, <math>b=1</math>, <math>d=1.2</math> using numerical integration of the partial differential equation with the diffusion constants <math>D_C=1</math>, <math>D_D=2</math>. The initial configuration is a circular disk of equal densities of cooperators and defectors (<math>0.1</math>) in the center of a square lattice with fixed (reflecting) boundary conditions.}}
