Gaia Hypothesis (Ecology)

Finding
The Daisyworld model demonstrates that organisms collectively stabilize planetary temperature without intent. White daisies reflect sunlight (cooling) and dominate when warm; black daisies absorb sunlight (warming) and dominate when cool. Differential growth rates produce regulation without design. This is homeostasis (entry 11) scaled from organism to planet.
Pattern Mapping
Proportion — Daisyworld demonstrates that proportion (response calibrated to deviation) can emerge without a centralized controller. Daisy populations adjust proportionally to temperature deviation.
Humility — The Gaia hypothesis, especially in its strong form, has been criticized for overreach. The honest version is the weak form: feedback without intentionality. Regulation emerges from selection without design.
Connections
- Gaia Hypothesis (Strong vs Weak) — the same hypothesis from the EARTH perspective, with the strong/weak distinction
- Homeostasis — Gaia extends homeostasis from organism to planet (→ Meta-Pattern 09: Feedback/Homeostasis)
- Lotka-Volterra Equations — both: dynamic equilibrium from competing populations
- Long-Term Carbon Cycle — the geological thermostat is weak Gaia in action
- Mycorrhizal Networks — cooperation emerging from structural coupling, not intent
Status
Daisyworld is a well-studied mathematical model. Weak Gaia (biotic feedback) broadly accepted. Strong form not mainstream. See Lenton, Nature 394, 1998. The mapping to the five properties is this project’s structural interpretation.
