| Gaia's Daisyworld concept. An imaginary world completely covered with the seeds of two types of flowers, white and black. The black flowers are better at absorbing light from the sun; the white flowers are better at reflecting light. In cooler conditions, the black flowers proliferate, and because they retain heat they eventually warm up the environment to a point where the ability to reflect heat becomes advantageous, allowing the white flowers to proliferate. |
