Earth's self-adjustment hypothesis
Life on earth has about 35 billion for the solar system,but the Venus and Mars to earth,but there is no life on the basic of detector,so that the reality is really is because the earth and the sun is suitable distance?In more than 30 years ago,British researchers rove Locke atmospheric chemistry proposed issue unique opinion:earth self-adjustment,referred to as Gaia hypothesis.Gaia is the mother of god in Greek mythology.Earth's self-adjustment hypothesis and the global environment and life as an integral system of two parts,the life constantly automatic adjustment in the earth for their survival environment.And had life on Mars today,therefore,also won't have life.35 million years ago,when the first appeared in life is completely different from the earth,and then today just just from the dust and gas,and the gas clouds rock was born,although when atmospheric composition,but not with carbon element mainly comprised of gas is undoubtedly,thick carbon dioxide,may also have no oxygen; methane,Then the sun also and now,according to the theory of evolution,the stars of the temperature of the sun than now 25-30% of low temperature.Early in the surrounding air of the greenhouse effect of carbon oxygen to keep the earth warm,continuation of life,but as the sun rises,the temperature of hot water vapor,more and more into the atmosphere,plus some YiYiDun contains carbon dioxide in carbonate rocks,continue,the greenhouse effect,the earth would eventually will be out as Venus is that,the surface is strong,the carbon dioxide gas temperature can lead to melt.Fortunately,in about 20 million years ago,sea,they began to appear algae through photosynthesis of carbon dioxide into the air of organic carbon compounds.For eons,algae and play into the plant has been greatly evolution and reproduction,therefore increased carbon dioxide in the atmosphere of the good and just keep pace with the speed of warming.The theory is that:is life itself had saved the life world.On the other hand,the earth from the date of birth,never calm,besides all sorts of droughts and floods,earthquakes,cyclones and tsunamis and volcanic eruptions aspect,it also consistently rock fragments from space by bombardment.Most of the meteorites,become harmless meteor,a few large enough to reach the ground.About 100 million years,average a huge impact on earth,earth meteoritic atmosphere with plenty of dust and gas,cover living sunshine,make the great tragedy,a large number of extinction,the latest occurs in about 65 million years ago,and at that time the extinction of the dinosaurs ruled the land.Earth's self-adjustment hypothesis that the extinction of the dinosaurs,supporters of the new species is to support the hypothesis of evidence.They think,life on earth and the environment is the combination of the health system and can quickly repair their wounds.Although disaster life of the global environment will be suspended control,but in fact,life will quickly restore control and start up adjustment function.But this does not mean that the earth had no change is updated,species environmental change.Anyhow,according to this hypothesis,life on earth and the system environment is generally stable,no big change,but when the system is beyond their ability to adjust the very condition,also will mutate.This hypothesis has been very fierce debate,some people think that it is not science,but to this philosophy,even some people say it is a religion.
