History of evolutionary thought [SEP] Gaia hypothesis
The Gaia hypothesis proposed by James Lovelock holds that the living and nonliving parts of Earth can be viewed as a complex interacting system with similarities to a single organism, as being connected to Lovelock's ideas. The Gaia hypothesis has also been viewed by Lynn Margulis and others as an extension of endosymbiosis and exosymbiosis. This modified hypothesis postulates that all living things have a regulatory effect on the Earth's environment that promotes life overall.
