London. About 20 million years on Earth before life came oxygen was present. In ancient times on Earth methane, ammonia and other Vishaktgas was dominated by the haze, so that form of life exists on earth today he was not present at the initial time. New study has found.
International team of University of New Jersey Rtjrs claimed millions of years ago when the wind was not able to breathe on earth, the oceans as many bacteria were present in the plants, the researchers found evidence of the nitrogen cycle nearly two researchers from South Africa three billion years old based on analysis of marine rocks conclusion.
According to The Daily Taligraf cycles of nitrogen in refinery Rtaon research found evidence that it is not possible without oxygen. Nitrogen cycles, which means people concerned with living things, and obviously for the origin of complex organic compounds will be using nitrogen. Nitrogen cycles information about the presence of life give evidence. According to scientists of photosynthesis by organisms as a sub product must be Oksgin emissions and about one billion years ago Adhai be born.
One billion years ago, gas was the best Nitrogen
He said about one billion years ago the atmosphere was rich in nitrogen gas. Scientists said that the first two billion years of Earth history, the presence of the gas in the atmosphere was very low, but because of photosynthesis on Earth came when oxygen first time, no definite information about it is not. The research was published in the journal Nature, scientists have Jiosains.
