The scientists found that 3 billion 700 million years ago the ancient earth fossil record of life – refresh Beijing Chinese daily on 1 September, according to the "Washington Post" reported on August 31st, about 3 billion 700 million years ago microbial mat the scientists have discovered fossils. If confirmed, this will be the oldest fossil in the history of the earth, the original record of more than 200 million years in advance. If the study is true, it means that life will soon come into being after the formation of the earth. Wollongong Australia University geologist Alan Terman (Allen Nutman)? The study of geology since 1880s. In July 2012, the team where he found seats about 1 to 4 cm long fossil microbes in Greenland Isua accident, looks like stromatolites. Subsequent laboratory analyses revealed that these fossils have been around 3 billion 700 million years old. If confirmed, this will create a new record of the earth’s oldest signs of life, than previously found in Western Australia, about 3 billion 500 million years ago which was 200 million years earlier about. The research results were published in the journal Nature in August 31st. The earth was formed about 4 billion 500 million years ago, and if there was life on earth about 3 billion 700 million years ago, it could mean that life exists in the universe. Schopf comments University of California at Los Angeles paleontologist believes that if the results of this study are true, the Earth early life, may mean that the universe appears on each planet of life is a common thing. He said: "at least on a planet like earth, life is much faster and easier than you think. If everything is true, there must be a lot of life in the universe, because there are many earth like planets in the universe." The publication of research evidence related to paleontology will inevitably be controversial. NASA’s Jet Propulsion Laboratory (NASA) geologist Abigail? Wood orr said that the conclusions of multiple evidence but no trivial matter, but not in the context of the ideal so clear. Orr Wood said, "they may really be biological, but also difficult to deny the possibility that they are by the sea water into local mineral deposits. If we find this on Mars, will we put a flag and announce that we have found life on Mars? I don’t think so, but we’re going to be very excited." The face of challenge, the Terman said: "we expect that there will be some intense debate. Science is like this. There will be people who make different assumptions, but I think we’ve got all the possibilities." (Translator: Wang Qichen editor: Shen Yang, Gao Linlin)相关的主题文章:
