The Gaia hypotheses: Are they testable?
James Lovelock and the Gaia hypothesis | New Scientist
In 1912 a German meteorologist named Alfred Wegener (1880-1931) hypothesized a single proto-supercontinent that divided up into the continents we now know because of continental drift and plate tectonics. This hypothesis is called Pangaea because the Greek word "pan" means "all" and Gaea or Gaia (or Ge) was the Greek name of the divine personification of the Earth. Discover the science behind how Pangaea broke apart millions of years ago.

Gaia hypothesis: the original version — the Earth’s organisms regulate the physical and chemical components of the earth system so as to maintain the planet as an optimal habitat for life.

The Gaia hypothesis sees life regulating the surface temperatureof Earth. The average surface temperature of Earth has remained withina narrow range - between 10 and 20 C - for over three billion years. During that time the sun's output has increased by thirty or forty percent. Even ignoring the long-term trend of the sun, the temperature would varyfar more, as it does for example every day on the surface of Mars
organism as the Gaia hypothesis predicts
Gladly we accepted his suggestion and Gaia is also the name of the hypothesis of science which postulates that the climate and the composition of the Earth always are close to an optimum for whatever life inhabits it.

then the steady state will be whichever side of the optimum leads to negative feedbacks, thus enhancing the stability of the physical system. The “optimal for life” in the original Gaia hypothesis is replaced by “mutually enhanced stability of the physical and biological systems”.
