A research report released on Thursday, said that the cause of biological extinction of 25 million years is climate change, not the asteroid caused the earth. After years of research, several ancient biologist team concluded: two stacks At the end of the year, 90% of the marine life and 75% of land biological extinction are the rising atmospheric temperatures, and the culprit is the greenhouse effect caused by volcanic eruption. The researchers pointed out that, until now, in the interpretation of the biggest disaster in the life of the Earth, the most acceptable theory is that a huge star falls to the earth or comet collision with the Earth and leads to global climate mutations. The leader of the research group, Peter, Ward of Washington, is explained: "According to the geographical chemistry characteristics we found, the extinguishing of the ocean and land creatures is gradually progressive. Land organism and marine life seem to be the same period, due to the same The cause of death is mainly the temperature of too high and hypoxia. "He further pointed out that there is hardly discovered that the crowd hits the characteristics of sudden disasters. Researchers carefully studied 127 reptiles and amphibians of skull fossils. These fossils are found in a deposit of 300 meters deep in Carro Basin South Africa. The history of these deposits can be traced back to the end of the two-fold, and the third stack is beginning. According to these chemistry, biological and magnetism, scientists have concluded that biological gentry is in about 10 million years, and this extinction speed is accelerated in subsequent 5 million. Under the leadership of Grees, Australia, another ancient biologist analyzed the sediments in Australia and China, and some chemical characteristics found that there were hypoxia in seawater at that time, and there were many survivals at the time. Bacteria in sulfur. These findings of the study of the study of South Africa sediments showed that the content of oxygen in the earth at that time was less, and the sulfur-containing gas contained in volcanic eruptions was discharged. Peter. Ward explained: "I think the global temperature is getting higher and higher, and finally reaches the critical point of the various forms of life." Although this phenomenon occurs, the oxygen in the atmosphere is thinned.
