Hypothesis can be named to anything that proposes beliefs.

In his book, 'On Gaia: A Critical Investigation of the Relationship between Life and Earth', Toby Tyrrell, Professor of Earth system science at the University of Southampton, concludes that the Gaia Hypothesis is not consistent with modern scientific evidence and understanding and should therefore be rejected.

This theory is the one that gave her the credibility to advance the Gaia Hypothesis....

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.

Viking found nothing on Mars,but Lovelock had seen the Earth from the perspective of an ET looking forevidence of life.

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.

He suggests that many people point to evidence for one of the weak forms of Gaia, and then go on to claim a stronger form.

Geophysiology, the science of Gaia – James Lovelock

As a result, the Earth's surface may have froze mostly or thinly solid through equatorial regions ("" versus "" Earth hypotheses). This chill may have lasted until the level of atmospheric carbon dioxide gradually rose to 350 times today's concentration after millions of years of volcanic activity (with a similar increase in methane) and a sudden meltdown occurred -- resulting in an "Acidic Hothouse" (. Microbial life, however, should have survived in or around cracks in warm ocean seafloors, deep volcanic vents, surface volcanic springs, and other warm niches. A Snowball to Acidic Hothouse swing would have greatly added to already high evolutionary pressures from anaerobic extinctions through genetic isolation of selective survival adaptations and may have led singled-celled eukaryotic organisms to cooperate together physically and form the first lifeforms.

However, life arose under these conditions, and there is geological evidence of flowing water from this time.

What are the arguments for and against the Gaia hypothesis

Approaching our home worldas Gaia, a name derived from ancient Greek polytheism, offers us amodern Earth-centered and mostly pantheist spirituality based on abelief that the Earth as a superorganism that supposedly has passedthrough billions of years of evolution. The modern emergence of thisEarth-centered philosophy stems out of the accepted Gaia theory whichinterprets the science behind the Earth as an ancient, living andself-regulating system within systems.

The Critical Period Hypothesis proposes that the human brain is only malleable, in terms of language, for a limited time.

Two models emerge: The model that life influences planetary processes (i.e., it has a substantial effect on abiotic processes) has become known as the weak Gaia hypothesis. This model is widely supported.
