James Lovelock and the Gaia hypothesis | New Scientist
The Gaia Hypothesis proposes ..
It considers some of the great questions about the nature of our planet, its history, and how it came to give rise to us. Many fascinating topics are covered, often from little-known corners of the natural world. Examples include: hummingbirds in the High Andes and the similarity of their beaks to the flowers they extract nectar from; the wonderfully-named Walsby's square archaeon in the Dead Sea; the ever-lasting durability of the waste that coral reefs generate; changes in the nature of the saltiness of seawater over geological time; and differences in the way Australian snakes bear young depending on climate.
Atmospheric homeostasis by and for the biosphere: the Gaia hypothesis
Professor Tyrrell's book submits the Gaia Hypothesis to detailed scrutiny, subjecting each of three main arguments put forward in support of Gaia to close analysis, and comparing them to evidence collected in the more than 30 years since the Gaia Hypothesis was first proposed. It is the first book containing a hard-nosed and thorough examination of the Gaia Hypothesis.
16/05/2012 · New Evidence to Support the Gaia Theory
The most difficult and the dirtiest criticism of Gaia is that there is nothing new in the idea, that it has all been said before&emdash;difficult, because there is much truth in it; dirty, because, as William James said of the fate of any new idea, "First, it's absurd, then maybe, and last, we have known it all along". Most biologists and many geochemists are ignorant of the details of control theory, the domain of engineers and physiologists. Merely for them to say it was explained by the balance of nature long ago is not enough. If it were, then explanations of why the concentration of oxygen is at 21 per cent, or of why the climate has remained favourable for 3.6 thousand million years, would already be available. Before the advent of the Gaia hypothesis, such questions were rarely asked, and would have been as pointless as asking an anatomist or a biochemist how human temperature is regulated. Such questions about systems cannot be answered from the separated disciplines of biochemistry or biogeochemistry, nor from neo-darwinist biology. The answer comes from physiology or control theory.
