科学家正在地球最古老的岩石中搜寻17亿年前的微小化石，以阐明单细胞微生物如何演变成植物、动物等复杂生命形式的过程。1真核生物至少在17亿年前就已出现，1而植物和动物王国的共同祖先时间约在16亿年前。1微生物在地球历史中占据了大约90%的时间，1这使得对早期真核生物的研究对于理解生命演化史具有关键意义。1
研究团队在挪威斯瓦尔巴群岛附近100平方公里区域进行调查。1此外澳大利亚去年也发现了约17.5亿年前的真核生物微化石。1约5.4亿年前的埃迪卡拉纪/寒武纪转变期标志着动物多样性发展的关键时期。1这项研究对揭示地球生命演化过程和预测地外世界是否可能存在复杂生命具有重要意义。1
Scientists are searching Earth's oldest rocks for microscopic fossils dating back 1.7 billion years to understand how single-celled microorganisms evolved into complex life forms such as plants and animals.1 This research holds significant implications for comprehending the history of life on Earth and predicting whether complex life might exist on other worlds.1
Eukaryotes emerged at least 1.7 billion years ago, during a period when microbes dominated Earth's history for approximately 90% of its timeline.1 The common ancestor of plants and animals kingdoms existed roughly 1.6 billion years ago.1 A critical period for animal diversity development occurred during the Ediacaran-Cambrian transition approximately 540 million years ago.1
Researchers are conducting investigations in a 100-square-kilometer area near Svalbard in Norway.1 Recent discoveries in Australia uncovered eukaryotic microfossils dating back approximately 1.75 billion years, contributing to evidence for early complex cellular life.1
