When investigating how ice ages begin and end, and feedbacks are considered. A positive feedback will accentuate a dynamic and a negative feedback will mute it. In the 1970s, and the author of today’s , , , which posits that Earth has provided feedbacks that maintain environmental . Under that hypothesis, environmental variables such as atmospheric and levels, levels, and Earth’s surface temperature have been kept relatively constant by a combination of geophysical, geochemical, and life processes, which have maintained Earth’s inhabitability. The homeostatic dynamics were mainly negative feedbacks. If positive feedbacks dominate, then “runaway” conditions happen. In astrophysics, are responsible for a wide range of phenomena. A runaway greenhouse effect may be responsible for . Climate scientists today are concerned that burning the hydrocarbons that fuel the industrial age . Mass extinctions are the result of Earth's becoming largely uninhabitable by the organisms existing during the extinction event. The ecosystems then collapse Mass extinction specialist recently proposed his as a direct challenge to the Gaia hypothesis.

This simple model hassince become an integral part of the debate about the Gaia Hypothesis.

Meaning of Gossip-Grooming Hypothesis medical term

There was a “” in the early Triassic, and depending on the framework and which scientist is asked, it took Earth’s ecosystems (when the environment recovered enough to sustain normal ecosystems), (when terrestrial ecosystem diversity recovered), or (when marine ecosystem diversity recovered) to recover from the Permian extinction. On land, the forests slowly recovered, and dominated the early Triassic. dominated the Southern Hemisphere, and palm-tree-resembling and ginkgo trees (which first appeared in the late Permian, of which the living fossil is the only surviving member) also prospered. In the , on what became North America, Europe, and Siberia, conifer forests recovered and blanketed the land.

Those interrelated and often mutually reinforcing lines of evidence have made many scientific findings difficult to deny. The ever-advancing scientific toolset, and the ingenuity of scientists developing and using them, and particularly the multidisciplinary approach that scientists and scholars are increasingly using, have made for radical changes in how we view the past. Those radical changes will not end any time soon, and what follows will certainly be modified by new discoveries and interpretations, but I have tried to stay largely within the prevailing findings, hypotheses, and theories, while also poking into the fringes and leading edges somewhat. Any mistakes in fact or interpretation in what follows are mine.


The Evolutionary Origin of the Fatty Acid Hypothesis …

The moon rocks retrieved by astronauts are still being tested, as new experiments and hypotheses are devised. In 2012, which resulted from testing moon rocks for the ratios (both are stable isotopes), and it has brought into question the hypothesis that the Moon was formed by a planetary collision more than four billion years ago. The titanium ratio was so much like Earth’s that a collision with Earth forming the Moon has been questioned (as very little of the hypothesized colliding body became part of the Moon). The collision hypothesis will probably survive, but it may be significantly different from today’s hypothesis. , as well as , and their ages confirm that geologists have derived, and meteorite dates provide more evidence that our .

AN EVOLUTIONARY HYPOTHESIS OF SUICIDE: WHY IT …

I was also regularly dismayed by orthodox scientific and academic works that dealt with the human brain, consciousness, human nature, , FE technology, and the like, in which the authors accepted declassified government documents at face value (as in not wondering what else remained classified, for starters) or looked no further than 19th-century investigations. Direct personal experience is far more valuable than all of the experimental evidence that be amassed; there is no substitute for it, as that is where comes from. Armchair scientists who accept the skeptics' word for it have taken the easy way out and rely on unreliable "investigators" to tell them about the nature of reality. They consequently do not have informed opinions, or perhaps more accurately, they have opinions. The holy warriors’ efforts aside, the scientific data is impressive regarding what has been called “psi” and other terms, which clearly demonstrated abilities of consciousness that are still denied and neglected by mainstream science. , but he was a voice in the wilderness.

I then review the evolutionary medical hypothesis …

White science still has almost nothing to say about the nature of consciousness. However, Black Science (covert, largely privatized, and the same province where that ) is somewhat familiar with the nature of consciousness and considers it to be far more than a byproduct of chemistry. The assumption that the entire universe is a of consciousness is not only by White Science, but is probably a foundational assumption of Black Science mystics.
