Watson and Lovelock's Daisyworld shows how life can regulate a planet. Black daisies warm a cold world by absorbing sunlight; white daisies cool a hot one by reflecting it. As the sun brightens, the daisy mix shifts to hold the temperature nearly constant — biological homeostasis with no foresight.

Governing equation

\frac{d A _{w}}{d t} = A_{w} (x β (T) - γ), β (T) = 1 - 0.003265 (295.5 - T)^{2}, L = 0.70

Reading this result: Under a dim sun (L=0.70), dark black daisies (20%) take over and absorb sunlight, warming the planet toward the temperature life prefers.
