The name Gaia is drawn from Greek mythology and means Mother Earth.
James Lovelock, an atmospheric chemist, and Lynn Margulis, a microbiologist, published their first paper on the Gaia hypothesis in the early 1970s. Their hypothesis stated that the biota, which consists of all living organisms, maintain an environment on Earth that is optimal for life. This environment features an atmosphere that has a stable temperature and chemical composition.

The Gaia hypothesis was later refined to emphasize that the...
