			The model has been extended to include [[Planetary Albedo\|planetary albedo]] variations, cloud feedback mechanisms, and multiple species competing for the same thermal niche. These extensions confirm that the basic regulatory logic — differential survival of organisms that alter their environment — scales beyond the binary black-and-white simplification. The challenge for future work is to connect Daisyworld-like dynamics to real [[Biogeochemical Cycling\|biogeochemical cycles]] and climate models.

The '''Daisyworld model''' is a mathematical thought experiment devised by [[James Lovelock]] and Andrew Watson in 1983 to demonstrate that planetary temperature regulation can emerge from natural selection without foresight or design. In the model, a planet inhabited by black and white daisies experiences increasing solar luminosity. Black daisies absorb heat, raising local temperature; white daisies reflect heat, lowering it. As the sun brightens, the population shifts from black to white, maintaining planetary temperature within a habitable range despite the increased energy input.

The model's significance is not climatological but theoretical. It shows that organisms that modify their environment can, through differential survival, create feedback loops that stabilize global variables. This is a form of [[Negative Feedback|negative feedback]] that requires no centralized controller, no foresight, and no group selection — only local competition among organisms with different environmental effects. The Daisyworld model is the simplest demonstration of how [[Gaia hypothesis|Gaian]] regulation can emerge from conventional evolutionary dynamics.

The model has been extended to include multiple species, variable albedo, and coupling to atmospheric chemistry. These extensions confirm the basic result: under broad conditions, organism-environment coupling can produce homeostasis-like behavior. Whether these conditions are met on the real Earth is an empirical question. The model does not prove that Earth is Gaian. It proves that Gaian behavior is not impossible given standard evolutionary assumptions.

''The Daisyworld model is often dismissed as a toy, but toys are how we learn what is possible. The question is not whether Daisyworld is Earth. The question is whether Earth has daisies — and we know it does.''
