gaia hypothesis science definition

The Gaia hypothesis ( / ˈɡaɪ.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.

Gaia hypothesis. 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 scientific investigation of the Gaia hypothesis focuses on ...

The Gaia Hypothesis suggests that Earth and its biological systems function as a single entity with self-regulatory feedback loops to maintain conditions favorable for life. AI generated definition based on: Encyclopedia of ... More recently, the terms Gaian science or Gaian theory have become more common than the original Gaia hypothesis ...

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. It postulates that all living things have a regulatory effect on the Earth ...

In science, 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. The Gaia hypothesis suggests that organisms and ecosystems on Earth cause substantial changes to occur in the physical and chemical nature of the environment, in a manner ...

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. The Greek word Gaia, or Gaea, meaning "Mother Earth ...

to assess the current, more focused Gaia hypothesis, and to outline the difficulties that it poses. Gaia contains elements of fact, theory, and wishful thinking. One part of Gaia that is clearly fact is the recognition that Earth's organisms have a significant effect on the physical and chemical environment. Biogeochemists have devoted

Gaia has been a fruitful hypothesis generator, and has prompted many intriguing conjectures about how biological processes might contribute to planetary-scale regulation of atmospheric chemistry and climate. In many important cases, however, these conjectures are refuted by the available data.

James Lovelock first formulated the Gaia Hypothesis in the 1960s, as a result of his work for NASA on developing methods of detecting life on Mars. At first, the theory was a way to explain the stable concentrations of chemicals such as oxygen and methane that persisted in Earth's atmosphere. Lovelock suggested that detecting such unstable ...

The Gaia hypothesis states that the temperature and composition of the Earth's surface are actively controlled by life on the planet. It suggests that if changes in the gas composition, temperature or oxidation state of the Earth are caused by extraterrestial, biological, geological, or other disturbances, life responds to these changes by ...

It is based on the idea that, over the long run of geological time, life may control the powerful physical forces for its own good. "The Gaia hypothesis states that the lower atmosphere of the earth is an integral, regulated, and necessary part of life itself. For hundreds of millions of years, life has controlled the temperature, the chemical ...

The Gaia Hypothesis: What Is It? First articulated by British atmospheric chemist James Lovelock, the Gaia hypothesis, succinctly, suggests that the Earth is a self-regulating, self-sustaining entity, which continually adjusts its environment in order to support life. Though a scientific theory, the Gaia hypothesis has, since

Gaia theory, which describes the life-environment system of the Earth as stable and self-regulating, has remained at the fringes of mainstream biological science owing to its historically inadequate definition and apparent incompatibility with individual-level natural selection. The key issue is whether and why the biosphere might tend ...

Gaia hypothesis. The Gaia (pronounced GAY-ah) hypothesis is the idea that Earth is a living organism and can regulate its own environment. This idea argues that Earth is able to maintain conditions that are favorable for life to survive on it, and that it is the living things on Earth that give the planet this ability.

Gaia Hypothesis. The Gaia hypothesis is an ecological hypothesis proposing that the biosphere and the physical components of the Earth (atmosphere, cryosphere, hydrosphere and lithosphere) are closely integrated to form a complex interacting system that maintains the climatic and biogeochemical conditions on Earth in a preferred homeostasis.

The Gaia hypothesis' central theme is that biological processes homeostatically maintain, on a planetary scale, geochemical and climatic conditions favorable for life. A number of distinct ...

and mechanistic science, and partly revived in the Naturphilosophie of 19th century German romanticism. For contemporary scientists, and evolutionary biologists in particular, Gaia also reminded them of the idea, linked with natural theology, that there is a "balance of nature". The Gaia hypothesis was altogether considered to be an extreme form

The uncertainties surrounding global climate change provide ample evidence, if any were necessary, of the need for a whole-system view of the Earth. Arguably the most visible - and controversial - attempt to understand Earth as a system has been Lovelock's Gaia theory. Gaia has been a fruitful hypothesis generator, and has prompted many intriguing conjectures about how biological processes ...

The Gaia Theory postulates that the Earth's climate and chemical composition have been regulated to support life, viewing Earth as a self-regulating organism.

This teaching unit begins with a conceptual sketch of the Gaia Hypothesis, followed by a way of thinking about teaching found in John Dewey's philosophy of education that meets the challenge of Gaia in the classroom. There follows an outline of how Dewey unites scientific and moral problem solving for developing social policy which is, in turn ...

Daisyworld is a computer model designed to help prove the Gaia hypothesis. (CC0 Public Domain / Unsplash - Micheile Henderson) To demonstrate the scientific validity of the Gaia hypothesis, Lovelock developed a computer model which he called Daisyworld. The Daisyworld model shows, for example, how a planet's inhabitants can work to stabilize its temperature, even as the intensity of its ...
