Gaia Hypothesis - an overview | ScienceDirect Topics
2005年3月4日 · Arguably the most ambitious ecological theory based on self-organization is the Gaia hypothesis, which postulates that the biosphere itself evolves to a homeostatic state. Lovelock suggested the Daisyworld model as an illustration of how this process might occur.
Gaia Theory - an overview | ScienceDirect Topics
Under this perspective, according to Gaia's theory (Margulis and Sagan, 1997; Lovelock, 2000), the world as a whole can be interpreted as an entire, complex, and self-regulating organism (Laszlo, 1996). Individual ecosystem components and the biosphere as a whole are the products of a continuous and never completed process of self-organization ...
Taking the Gaia hypothesis at face value - ScienceDirect
2022年3月1日 · The Gaia hypothesis (GH) has been fundamental in the development of what is now called Earth System Science (Lawton 2001; Turney 2003; Steffen et al. 2020), and key to the understanding of atmospheric carbon-based molecules as greenhouse gases that have a crucial effect on biosphere lifespan, long-term habitability and climate feedbacks (Lovelock and Watson 1982; Lovelock and Whitfield 1982).
Making Evolutionary Sense of Gaia - ScienceDirect
2019年10月1日 · Traditional neoDarwinists hold this to be impossible in theory. But the hypothesis does make sense if one treats the clade that comprises the biological component of Gaia as an individual and allows differential persistence – as well as differential reproduction – to be an outcome of evolution by natural selection. Recent developments in ...
Is Gaia alive? The future of a symbiotic planet - ScienceDirect
2018年12月1日 · My thought experiments aim to keep alive and stimulate the discussion about Gaia theory and its implications for our and the whole biosphere’s future. I proposed, with a logic-deductive reasoning and analogical arguments that, without invoking teleology, so without any foresight or planning, a Gaian planet can be considered as a ...
Do evolution and ecology need the Gaia hypothesis?
2007年11月1日 · Gaia theory, which describes the life–environment system of the Earth as stable and self-regulating, has remained at the fringes of mainstream biological science owing to its historically inadequate definition and apparent incompatibility with individual-level natural selection. The key issue is whether and why the biosphere might tend ...
The Gaia hypothesis: the verdict is in - ScienceDirect
2013年10月26日 · I was also fortunate to attend several conferences on Gaia, in Valencia, Spain, and in Oxford, along with luminaries such as the evolutionary biologists Bill Hamilton and John Maynard Smith; Lynn Margulis, who established endosymbiosis, the idea that one organism can live symbiotically within another; and Heinrich “Dick” Holland, an expert in the great oxygenation event, when oxygen first ...
Do evolution and ecology need the Gaia hypothesis?
2007年11月1日 · Hence, evolutionary biologists have tended to ignore Gaia theory and the literature on Gaia [4], with some notable exceptions 5, 6, ignores much biological theory and, especially, experiment. Here, we define carefully what is meant by ‘Gaia’ and the properties it must have, describe its relationship to traditional ecology and evolution, and ...
Gaia again - ScienceDirect
2009年1月1日 · The connection between biological theory and thermodynamics has been established before (e.g., Ulanowicz and Hannon, 1987, Brooks and Wiley, 1988, Collier, 1986, Schneider and Kay, 1994). In particular, the maximum entropy production principle has been used in attempts to understand Gaia theory (as reviewed in Wood et al., 2008, Kleidon, 2004 ...
Beyond planetary-scale feedback self-regulation: Gaia as an …
2021年1月1日 · Recent advances on Gaia theory may allow us to understand anticipation on a planetary scale by identifying a Markov blanket -autopoietic- boundary for the Earth's climate system (Rubin et al., 2020; Rubin and Crucifix, 2017). This suggests that any attempt of “Earth stewardship” may involve making inferences from Gaia's own inference.
