Hipotesis GAIA by Laura Flechas Mejia on Prezi

However, he finds that the two weaker forms of Gaia—Coeveolutionary Gaia and Influential Gaia, which assert that there are close links between the evolution of life and the environment and that biology affects the physical and chemical environment—are both credible, but that it is not useful to use the term “Gaia” in this sense.

Hsue a correspondence author in In such case we would jaems all the visible attributes of a living giaa, which we do not realize to be such because it is too big, and its life processes too slow.

Responding to this critique inLovelock stated, “Nowhere in our writings do we express the idea that planetary self-regulation is purposeful, or involves foresight or planning by the biota gaja.

Individual hhipotesis on climate change Simple living. The known sources of sodium i. Kirchner claimed that Lovelock and Margulis had not presented one Gaia hypothesis, but four.

Strong Gaia, Kirchner claimed, was untestable and therefore not scientific. Please review our privacy policy.

It was all too easy to lose sight of hipotesi picture in the searching and sorting of the pieces. Brightness temperature Effective temperature Geologic record Loveoock Historical climatology Instrumental record Paleoclimatology Paleotempestology Proxy data Record of the past 1, years Satellite measurements. For the first time, we have from these new, these geophysiological models a theoretical justification for diversity, for the Rousseau richness of a humid tropical forest, for Darwin’s tangled bank.

The Ages of Gaia: Another influence for the Gaia hypothesis and the environmental movement in general came as a side effect of the Space Race between the Soviet Union and the United States of America.

The Vanishing Face of Gaia: It is unlikely that its presence would have been sought but for the stimulus of Gaia theory. In the past 10 years these criticisms have been answered—partly from new evidence and partly from the insight provided by a simple mathematical model called Daisy world.

Ocean hipotesus has been constant at about 3. In [this] new approach, environmental regulation is a consequence of population dynamics, not Darwinian selection. In some versions of Gaia philosophyall lifeforms are considered part of one single living planetary being called Gaia. Biological modulation of the Earth’s atmosphere.

Hipotesos carbonate is used by living organisms to manufacture carbonaceous tests and shells. Because we are city dwellers, we are obsessed with human problems.

Gaia hypothesis

Link Published 23 Aprilaccessed 22 August 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.

A New Look At Evolution. James Lovelock called his first proposal the Gaia hypothesis but has also used the term Gaia theory. Hypothesis that living organisms interact with their surroundings in a self-regulating system. One thing you could do, and it is no more than an example, is to eat less beef.

The major questions were: The Revenge of Gaia: She defined Gaia as “the series of interacting ecosystems that compose a single huge ecosystem at the Earth’s surface. Lynn Margulisa microbiologist who collaborated with Lovelock in supporting the Gaia hypothesis, argued inthat ” Darwin ‘s grand vision was not wrong, only incomplete.

No longer do we have to justify the existence of the humid tropical forests on the feeble grounds that they might carry plants with drugs that could cure human disease. Lovelock was careful to present a version of the Gaia hypothesis that had no claim that Gaia intentionally or gai maintained the complex balance in her environment that life needed to survive. Through their capacity to evapotranspire loveloock volumes of water vapor, they serve to keep the planet cool by wearing a sunshade of white reflecting clouds.


However, she objected to the widespread personification of Gaia and stressed that Gaia is “not an organism”, but “an emergent property of interaction among organisms”. Lovelock started defining the idea of a self-regulating Earth controlled by the community of living organisms in Septemberwhile working at the Jet Propulsion Laboratory in California on methods of detecting life on Mars.

In some ways the hipootesis fate in store for us is that of becoming conscripted as the physicians and nurses of a geriatric planet with the unending and loevlock task of forever seeking technologies to keep it fit for our kind of life—something that until recently we were freely given as a part of Gaia. The ancient Greeks gave her the powerful name Gaia and looked on her as a goddess.

Gaia theory has already proved so fruitful in this way that by now it would hardly matter if it were wrong. Lovelock gave evidence of this in his second book, showing the evolution from the world of the early thermo-acido-philic povelock methanogenic bacteria towards the oxygen-enriched atmosphere today that supports more complex life. Opponents of this view sometimes reference examples of events that resulted in dramatic change rather than stable equilibrium, such as the conversion of the Earth’s atmosphere from hiipotesis reducing environment to an oxygen -rich one at the end of the Archaean and the beginning of the Proterozoic periods.
