我们从进化动力学中引入复制-突变机制到二维雏菊世界模型中，从而将进化变化与雏菊世界在生物群和环境之间的双向反馈耦合起来。雏菊世界在这些进化力量的存在下继续自我调节。最有趣的行为，表现出复杂的和动态的舞蹈，通过空间和时间的物种的丰度，出现通过引入添加剂时空随机扰动的热噪声的形式。生态系统反馈和生态系统波动之间的平衡决定了雏菊物种及其突变体或适应者之间优势域的空间共存。
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 perturbations 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.
