We introduce replicator-mutator mechanisms from evolutionary dynamics into a two-dimensional daisyworld model, thereby coupling evolutionary changes with daisyworld's bidirectional feedback between biota and environment. Daisyworld continues to self-regulate in the presence of these evolutionary forces. The most interesting behaviours, exhibiting a complex and dynamic dance through space and time in species' abundance, emerges through the introduction of additive spatio-temporal random

... ions in the form of thermal noise. The balance between ecosystem feedback and fluctuations in the ecosystem determines the spatial coexistence of domains of dominance between daisy species and their mutants or adaptants.
