White daisies reflect light, making the planet cooler. Black daisies absorb light, lowering he albedo*, or reflectivity, and thus making the planet warmer. But while daisies “want” warm weather, meaning that they thrive preferentially as temperatures rise. Black daisies want cool weather. These qualities can be expressed in a set of differential equations and the daisy world can be set in motion on a computer. A wide range of initial conditions will lead to an equilibrium attractor – and not necessarily a static equilibrium.
“It’s just a mathematical model of a conceptual model, and that’s what you want – you don’t want high-fidelity models of biological or social system.,” Abraham said. “Youjust put in the albedos, make some initial planting, and watch billions of years of evolution go by. And you educate children to be better members of the board of directors of the planet.” ~ Page 279
*the proportion of the incident light or radiation that is reflected by a surface, typically that of a planet or moon. ~ 279
