Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
Rare Earth was succeeded in 2003 by the follow-on book The Life and Death of Planet Earth: How the New Science of Astrobiology Charts the Ultimate Fate of our World, also by Ward and Brownlee, which talks about the Earth's long-term future and eventual demise under a warming and expanding Sun, showing readers the concept that planets like Earth ...
Because SparkNotes provides study guides for literature that include chapter summaries, many teachers see the website as a cheating tool. [7] These teachers argue that students can use SparkNotes as a replacement for actually completing reading assignments with the original material, [8] [9] [10] or to cheat during tests using cell phones with Internet access.
The Rare Earth hypothesis argues that planets with complex life, like Earth, are exceptionally rare.. In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the origin of life and the evolution of biological complexity, such as sexually reproducing, multicellular organisms on Earth, and subsequently human intelligence, required an improbable combination of astrophysical ...
The mythical Gaia was the primal Greek goddess personifying the Earth, the Greek version of "Mother Nature" (from Ge = Earth, and Aia = PIE grandmother), or the Earth Mother. James Lovelock gave this name to his hypothesis after a suggestion from the novelist William Golding , who was living in the same village as Lovelock at the time ...
States of suspended animation are common in micro-organisms and some plant tissue, such as seeds. Many animals, including large ones, may undergo hibernation, and most plants have periods of dormancy. This article focuses primarily on the potential of large animals, especially humans, to undergo suspended animation.
Karolina Olsson (29 October 1861 – 5 April 1950), also known as "Soverskan på Oknö" ("The Sleeper of Oknö"), was a Swedish woman who purportedly remained in hibernation between 1876 and 1908 (32 years). [1] This is believed to be the longest time that anyone has lived in this manner who then awoke without any residual symptoms. [2] [3]
Some editions of the book have a different, less optimistic subtitle: Earth's Climate Crisis and the Fate of Humanity. The book introduces the concept of the anti-CLAW hypothesis . Lovelock proposed that instead of providing negative feedback in the climate system, the components of the CLAW hypothesis may act to create a positive feedback loop .
