British scientists revealed the mechanism by which life on earth has benefited from the stability and climate of the ecosystem, which has helped it survive more than 3 billion years .
Trends in Ecology and Evolution Tim Linton, of the University of Exeter, UK, discovered two simple principles that govern the evolution of life on Earth before becoming a system self-stabilized: "How and why our ancestors appeared."
Astrophysics that life is supposed to fill the galaxy and the entire universe, but we have not yet found beings or intelligent animals on other planets, which has led many researchers to believe that this is related to the fact that this life appears and disappears quickly, without leaving a clear trace
.
The first explanation for this paradox was put forward by the famous British chemist James Lovelock in 1972, under the so-called Gaia hypothesis.
This hypothesis presents the climate and conditions organized by the population, the green plants and the living organisms. In the same way, the animals interact with those who have warm blood, with variable degrees
. illustrates the mechanism of maintaining life on Earth during this long period of time, it does not answer the most important question:
How the self-sufficiency system is formed and how the coexistence of life
Scientists show that many mutations can be beneficial to the survival of a species of microbes, animals or plants, but can destabilize the entire ecosystem, causing a rapid extinction of all existing organisms. Or other features of the surrounding environment.
A good example of this is the appearance of blue bacteria that caused the ice age a billion years ago, following a sharp decline in carbon dioxide in the & [[[[[[[[[[[[[[[[[[[[[atmospherewhichhaltedtheevolutionofanteriorlife
If the evolution is modest and slow, or changes associated with "external" factors like volcanic eruptions, the increase of the Solar activity or changes in the rock cycle in nature.
According to Linton, the evolution of stability is closely related to the next stage of the evolution of life. In the sense that living organisms disappear R, faster than other types of microbes and plants multi-cell organisms, which led to the formation of stable and fully self-regulating land, which we live today. 39; hui.
