The hypothesis was formulated by the chemist James Lovelock  and co-developed by the microbiologist Lynn Margulis in the s. Topics related to the hypothesis include how the biosphere and the evolution of organisms affect the stability of global temperature , salinity of seawater , atmospheric oxygen levels, the maintenance of a hydrosphere of liquid water and other environmental variables that affect the habitability of Earth. The Gaia hypothesis was initially criticized for being teleological and against the principles of natural selection , but later refinements aligned the Gaia hypothesis with ideas from fields such as Earth system science , biogeochemistry and systems ecology. Gaian hypotheses suggest that organisms co-evolve with their environment: that is, they "influence their abiotic environment, and that environment in turn influences the biota by Darwinian process ". Lovelock gave evidence of this in his second book, showing the evolution from the world of the early thermo-acido-philic and methanogenic bacteria towards the oxygen-enriched atmosphere today that supports more complex life. A reduced version of the hypothesis has been called "influential Gaia"  in "Directed Evolution of the Biosphere: Biogeochemical Selection or Gaia?

Este concepto recibe el nombre de homeostasis. Otro ejemplo es el sudor que nos permite refrigerar nuestro cuerpo cuando tenemos calor. Por tanto, Gaia se sirve de las plantas para mantener la temperatura ideal para los seres vivos.
De esta manera logran permanecer a la profundidad adecuada para sobrevivir. De esa misma forma, todas y cada una de las especies que habitamos el planeta Tierra, estamos unidos por fuertes lazos y somos imprescindibles para la supervivencia de Gaia. Debemos concienciarnos de la importancia de cuidar a todos los hijos de la Tierra y a la propia madre.
