科学家重建了LUCA的基因组,这是地球上所有生命中最后一个普遍共有的祖先,使用了700种细菌和考古基因组。 Scientists reconstructed LUCA's genome, the last universal common ancestor of all life on Earth, using 700 curated genomes from bacteria and archaea. 据估计，LUCA生活在42亿年前，其小基因组表明它很复杂，但缺乏光合作用或固氮的证据。 Estimated to have lived 4.2 billion years ago, LUCA's small genome suggests it was complex but lacked evidence of photosynthesis or nitrogen fixation. 这项研究对生命的起源和演变提供了新的视角。 This research offers new perspectives on life's origin and evolution.
