一项新的研究称,从澳大利亚发现的微型化石可以看出,在34亿多年前的无氧世界里,细菌曾在地球上大量存在,这一发现让人们对火星上有生命存在抱有更大希望。西澳洲大学和牛津大学的研究人员说,古老水成岩里含有的微生物化石引起了将近10年的争议,现在这些化石被确定为地球上发现的最古老的化石。 According to a new study, the micro-fossils found in Australia show that bacteria existed on Earth for more than 3.4 billion years ago in an anaerobic world. This discovery allowed people to have the existence of life on Mars More hope. Researchers at the University of Western Australia and the University of Oxford said that microbial fossils contained in ancient sedimentary rocks have caused controversy for nearly 10 years and are now identified as the oldest fossils found on Earth.
