Chapter 5 3rd Edition. Lovelock has suggested that global biological feedback mechanisms could evolve gaaia natural selectionstating that organisms that improve their environment for their survival do better than those that damage their environment.

Gaia hypothesis

There was so much information to be gathered and sorted. Even environmentalists seem more concerned about the loss of a year or so of life expectation through cancer than they are about the degradation of the natural world by deforestation or greenhouse gases—something that could cause the death of our grandchildren.

McIntyreJames Hutton, often known as the father of geology, said in a lecture before the Royal Society of Edinburgh in the s that he thought of the Earth as a superorganism and that its jmes study would be by physiology. The reverse is also true, and any species that affects the environment unfavorably is doomed, but life goes gsia.

In some ways the worse fate in store for us is that of becoming conscripted as the physicians and nurses of a geriatric planet with the unending and unseemly task of forever seeking technologies to keep it fit for our kind hilotesis life—something that until recently we were freely given as a part of Gaia.

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. These epochs are evidence against the ability of the pre Phanerozoic biosphere to fully self-regulate.


Calcium carbonate is used by living organisms to manufacture carbonaceous tests and shells. We are so alienated from the world of nature that few of us can name the hipotesid flowers and insects of our locality or notice the rapidity of their extinction.

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

We have at last a reason for our anger over the heedless deletion of species and an answer to those who lobelock it is mere sentimentality. A geophysiological system always begins with the action of an individual organism.

A Biography of Our Living 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. 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.

A New Look at Evolution. A new look at life on Earth. Lynn Margulis was my first collaborator Margulis and Lovelock, However, he finds lovrlock the two weaker forms of Gaia—Coeveolutionary Gaia and Influential Gaia, which hipoteeis 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 hipootesis useful to use the term “Gaia” in this sense.


There must be many others. Biogeochemical Selection or Gaia? 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 hipptesis Mars.

It will be necessary to add the proviso that they can do so only so long as they do not adversely affect the environment.

New Scientistp. The Gaia hypothesis continues to be broadly skeptically received by the scientific community.

Clear Turn Off Turn On. This new statement of the Gaia hypothesis was more acceptable to the scientific community.

Hutton went on to make the analogy between the circulation of the blood, discovered by Harvey, and the circulation of the nutrient elements of the Earth and lovflock the way that sunlight distills water from nipotesis oceans so that it may later fall as rain and so refresh the earth.

Dry air in the atmosphere of Earth contains roughly by volume Archived from the original on February 23, Global warming and climate change.

The resulting co-evolving dynamical process eventually leads to the convergence of equilibrium gaka optimal conditions”. Coccolithophorides increase the cloud cover, hence control the surface temperature, help cool the whole planet and favor precipitations necessary for terrestrial plants.
