The Gaia hypothesis (/ ˈ ɡ aɪ. ə /), also known as the Gaia theory, Gaia paradigm, or the Gaia principle, proposes that living organisms interact with their inorganic surroundings on Earth to form a synergistic and self-regulating, complex system that helps to maintain and perpetuate the conditions for life on the planet.
Apr 26, 2024 · Gaia hypothesis, model of the Earth in which its living and nonliving parts are viewed as a complex interacting system that can be thought of as a single organism. Developed c. 1972 largely by British chemist James E. Lovelock and U.S. biologist Lynn Margulis, the Gaia hypothesis is named for the Greek Earth goddess.
The Gaia hypothesis, also known as Gaia theory or Gaia principle, proposes that all organisms and their inorganic surroundings on Earth are closely integrated to form a single and self-regulating complex system, maintaining the conditions for life on the planet.
The Gaia hypothesis (Lovelock, 1972; Lovelock and Margulis, 1973) postulates: “the climate and chemical composition of the Earth’s surface environment is, and has been, regulated in a state tolerable for the biota” (Lovelock, 1989, p. 215).
May 23, 2018 · The Gaia hypothesis is a recent and controversial theory that views Earth as an integrated, pseudo-organismic entity, and not as a mere physical object in space. Gaia, Earth, was believed by the ancient Greeks to be a living, fertile ancestor of many of their important gods.
Lovelock called his idea the “ Gaia Hypothesis” and defined Gaia as. a complex entity involving Earth’s biosphere, atmosphere, oceans, and soil; the totality constituting a feedback of cybernetic systems which seeks an optimal physical and chemical environment for life on this planet.
Some have hailed Gaia as a profound discovery, while others have dismissed it as a ‘just-so story’ that is more entertaining than informative. Here I will argue that Gaia, in its different guises, is a mixture of fact, theory, metaphor, and wishful thinking.
Apr 15, 2021 · The Gaia hypothesis was introduced in the 1970s by James Lovelock and Lynn Margulis. The original idea proposed that near homeostatic conditions on Earth have been maintained “by and for the biosphere”.
Dec 18, 2003 · Gaia theory reconciles current thinking in evolutionary biology with that in evolutionary geology. It extends, not contradicts, Darwin's vision, just as relativity enhances,...
The Hypothesis. The Gaia hypothesis is nothing if not daring and provocative. it proposes plane-tary regulation by and for the biota, where the “biota” is the collection of all life. it suggests that life has conspired in the regulation of the global environment so as to keep conditions comfortable.
