Toward a Physiology of Earth. It is at least not impossible to regard the earth’s parts—soil, mountains, rivers, atmosphere etc,—as organs or parts of organs of a coordinated whole, each part with its definite function. Princeton University Press, p.

HIPÓTESIS GAIA by loreto cabrera on Prezi

This difference with the Earth atmosphere was considered to be a proof that there was no life in these planets. In the eighteenth century, as geology consolidated as a modern science, James Hutton maintained that geological and biological processes are interlinked. Carbon capture and storage Efficient energy use Low-carbon economy Nuclear power Renewable energy.

In [this] new approach, environmental regulation is a consequence of population dynamics, not Gzia selection. Basic Books,p. Link Lovelock, James Lovelock has also hypothesised that methanogens produced elevated levels of methane in the early atmosphere, giving a view similar to that found in petrochemical smog, similar in some respects to the atmosphere on Titan.

The composition of salt ions within our oceans and seas are: During the “philosophical foundations” session of the conference, David Abram spoke on the influence of metaphor in nipotesis, and of the Gaia hypothesis as offering a new and potentially game-changing metaphorics, while James Kirchner criticised the Gaia hypothesis for its imprecision.

The resulting co-evolving dynamical process eventually leads to the convergence of equilibrium and optimal conditions”. How plants changed Earth’s history. The Gaia hypothesis was an influence on the hpiotesis ecology movement. The elements that comprise salinity do not readily change and are a conservative property of seawater.

Gaia hypothesis – Wikipedia

Doolittle argued that nothing in the genome of individual organisms could provide the feedback mechanisms proposed by Lovelock, and therefore the Gaia hypothesis proposed no plausible mechanism and was unscientific.

In some versions of Gaia philosophyall lifeforms are considered part of one single living planetary being called Gaia. Archived from the original on 9 February The model demonstrates that beneficial feedback mechanisms can emerge in this “toy world” containing only self-interested organisms rather than through classic group selection mechanisms.

A new look at life on Earth. It would appear that the claim that Gaia acts “intentionally” was a metaphoric statement in his popular initial book and was not meant to be taken literally. A New Look at Evolution. Individual action on climate change Simple living. Less accepted versions of the hypothesis claim that changes in the biosphere are brought about through the coordination of living organisms and maintain those conditions through homeostasis.

Dry air in the atmosphere of Earth contains roughly by volume gaja Journal of Theoretical Biology. The flow of carbon dioxide from the atmosphere to the soil is therefore regulated with the help of living beings.

In the biogeochemical processes of the earth, sources and sinks are the movement of elements. Gaia hipotessi see the participation of living organisms in the carbon cycle as one of the complex processes that maintain conditions suitable for life.

An Introduction to the Earth-Life System. The originality of the Gaia hypothesis relies on the assessment that such homeostatic balance is actively pursued with the goal of keeping the optimal conditions for life, even when terrestrial or external events menace them. The hypothesis contends that this system as a whole, called Gaia, seeks a physical and chemical environment optimal for contemporary life.

Gaia hypothesis

A New Look at Life on Earth. Calcium carbonate is used by hipotfsis organisms to manufacture carbonaceous tests and shells. Lynn Margulis joined Lovelock in the effort of fleshing out the initial hypothesis into scientifically proven concepts, contributing her knowledge about how microbes affect the atmosphere and the different layers in the surface of the planet.

L’ambientalismo nuclearista di James Lovelock.

Retrieved 7 January Also in the turn to the 20th century Aldo Leopoldpioneer in the development of modern environmental ethics and in the movement for wilderness conservation, suggested a living Earth in his biocentric or holistic hipotess regarding land. Lynn Margulisa microbiologist who collaborated with Lovelock in supporting the Gaia hypothesis, argued inthat ” Darwin ‘s grand vision was not wrong, only incomplete.
