TEORÍA GAIA METÁFORA DEL CAMELLO Camellos regulan su temperatura corporal a dos niveles distintos pero estables: De día con calor. de una teoría Gaia científica partiendo de la hipótesis inicial de Lovelock: Gaia es un organismo evolutivo teleológico no necesariamente compatible.

James Lovelock and Andrew Watson developed the mathematical model Daisyworldin which temperature regulation arises ggaia a simple ecosystem consisting of two species whose activity varies in response to the planet’s environment. However, the composition of seawater is far from equilibrium, and it is difficult to explain this fact without the influence of organic processes.

Gaia tra mito e scienza. In some versions of Gaia philosophyall lifeforms are considered part of one single living planetary being called Gaia.

For example, against the charge that Gaia was teleological, Lovelock and Andrew Watson offered the Daisyworld Model and its modifications, above as evidence against most of these criticisms. Gaia scientists see the participation of living organisms in the carbon cycle as one of the complex processes that maintain conditions suitable for life.

Hamilton called the concept of Gaia Copernicanadding that it would take another Newton to explain how Gaian self-regulation takes place through Darwinian natural selection. Wholeness gwia Disintegration in Ecology and Science.

The flow of carbon dioxide from the atmosphere to the soil is therefore regulated with the help of living beings.

Retrieved 19 October The Gaia hypothesis hiporesis to be broadly skeptically received by the scientific community. These processes establish a global control system that regulates Earth’s surface temperatureatmosphere composition hipoteesis ocean salinitypowered by the global thermodynamic disequilibrium state of the Earth system. Kirchner claimed that Lovelock and Margulis had not presented one Gaia hypothesis, but four.


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”. The Life of an Independent Scientist. How plants changed Earth’s history.

Basic Books,p. Many scientists in particular also criticised the approach taken in his popular book Gaia, a New Look at Life on Earth for being teleological —a belief that things are purposeful and aimed towards a goal.

In a recent book-length evaluation hioptesis the Gaia hypothesis considering modern evidence from across the various relevant disciplines the author, Toby Tyrrell, concluded that: The Gaia theory posits that the Earth is a self-regulating complex system involving the biosphere.

It is hypothesized that these are created by bacterial colonies that fix ions and heavy metals during their life processes. The elements that comprise salinity do not readily change and are a conservative property of seawater. The colour of the daisies influences gaix albedo of the planet such that black daisies absorb light and warm the planet, while white daisies reflect light hipotesis de gaia cool the planet.

Lovelock gave evidence of this faia his second book, showing the evolution from the world of the early thermo-acido-philic and methanogenic bacteria towards the oxygen-enriched atmosphere today that supports more complex life.
