Gai·a hypothesis

1. A hypothesis stating that Earth's biota constitute a single interconnected system that affects or determines the physical and chemical conditions within the biosphere, including such conditions as global temperatures, the composition of the atmosphere, and the salinity of seawater.
2. Any of various related hypotheses stating that this system is self-regulating, as through feedback loops, or that it constitutes a living organism, in either case acting to maintain stable conditions that are optimal for the continuation of life.

[After Gaia, used by British scientist and environmentalist James Lovelock (born 1919) to refer to the totality of Earth's biota as a superorganism.]

You said at one point that the germ of the Gaia theory was your realization that the Earth had "an atmosphere that was wildly anomalous, and a strange, wonderful and beautiful anomaly that sort of shouted a song of life right across the solar system, right out into the galaxy."

As much as he praised Vernadskij's insights many years later, Lovelock said "I defy you to find, anywhere in Vernadskij's writings, a clear statement of the importance of feedbacks involving life in maintaining conditions suitable for life on Earth"--namely the key concept of Gaia Theory (Gribbin, 2009: 1004).
Gaia Theory has helped bridge huge schisms between disciplines within science, but by virtue of its mythology-inspired name, it hearkens to the deep connections between the human mind and Earth's living system.
