Organisms can greatly affect their environments, and the feedback coupling between organisms and their environments can shape the evolution of both. Beyond these generally accepted facts, the Gaia hypothesis advances three central propositions: (1) that biologically mediated feedbacks contribute to environmental homeostasis, (2) that they make the environment more suitable for life, and (3) that such feedbacks should arise by Darwinian natural selection. These three propositions do not fare… 

The Gaia Hypothesis: Conjectures and Refutations

Gaia theory predicts that organisms alter their environment to their own benefit, but throughout most of the surface ocean, nutrient depletion by plankton has almost created a biological desert, and is kept in check only by the nutrient starvation of the plankton themselves.

More than planetary-scale feedback self-regulation: A Biological-centred approach to the Gaia Hypothesis

12 Recent appraisals of the Gaia theory tend to focus on the claim that planetary life is a cybernetic 13 regulator that would self-regulate Earth’s chemistry composition and climate dynamics,

Environmental regulation can arise under minimal assumptions.

Symbiotic physiology promotes homeostasis in Daisyworld.

Self-organization and the Emergence of Complexity in Ecological Systems

Ecosystems and the biosphere are complex adaptive systems, in which cooperation and multicellularity can develop and provide the regulation of local environments, and indeed impose regularity at higher levels.

Beyond Gaia: Thermodynamics of Life and Earth System Functioning

Are there any general principles that govern the way in which life affects Earth system functioning? Most prominently, the Gaia hypothesis addresses this question by proposing that near-homeostatic

Thermodynamics and environmental constraints make the biosphere predictable – a response to Volk

I do not think that Volk makes convincing arguments that contradict MEP, although I certainly agree that there is a lot more work to be done to fully recognize the great importance that thermodynamics and MEP play in shaping the Earth’s biosphere and its evolutionary history.

The Gaia Hypothesis in the Context of Global Challenges of Modernity

The essential break in the connection between a human and nature, crisis situations and terrible cataclysms, loneliness, awareness of fragility of one's own being, which an individual face in his



The Gaia hypothesis: Can it be tested?

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 hypotheses

Testing the Effect of Life on Earth's Functioning: How Gaian Is the Earth System?

It is concluded that life has indeed a strong tendency to affect Earth in a way which enhances the overall benefit (that is, carbon uptake), however, this does not imply that the biota regulates Earth's environment for its own benefit.

Biological homeostasis of the global environment: the parable of Daisyworld

A model of animaginary planet having a very simple biosphere, consisting of just two species of daisy of different colours, sketches out the elements of a biological feedback system which might help regulate the temperature of the earth.

Gaia's body : toward a physiology of earth

The concept of Gaia resonates with a wide range of people -- from nature lovers, theologians, and philosophers to environmental and earth systems scientists. The term, which scientist James Lovelock,

The Gaia Hypothesis

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

Gaia and natural selection

Evidence indicates that the Earth self-regulates at a state that is tolerated by life, but why should the organisms that leave the most descendants be the ones that contribute to regulating their

Atmospheric homeostasis by and for the biosphere: the gaia hypothesis

During the time, 3.2 × 10 9 years, that life has been present on Earth, the physical and chemical conditions of most of the planetary surface have never varied from those most favourable for life.

Failure of climate regulation in a geophysiological model

THERE has been much debate about how the Earth responds to changes in climate—specifically, how feedbacks involving the biota change with temperature. There is in particular an urgent need to

The Evolutionary Advantages of Dying Young: Epidemiological Implications of Longevity in Metapopulations

It is shown that pathogen‐mediated selection can influence the evolution of host longevity, and that an organism's life‐history traits, and not just its resistance genes, can affect its risk of pathogen attack.


▪ Abstract Anthropogenic greenhouse gases are expected to induce changes in global climate that can alter ecosystems in ways that, in turn, may further affect climate. Such climate-ecosystem
