Evidence for the existence of life during the Archaean segment of Earth history (more than 2500 Myr ago) is summarized. Data are presented for 48 Archaean deposits reported to contain biogenic stromatolites, for 14 such units reported to contain 40 morphotypes of putative microfossils, and for 13 especially ancient, 3200-3500 Myr old geologic units for which available organic geochemical data are also summarized. These compilations support the view that life's existence dates from more than or equal to 3500 Myr ago.
总结了地球历史太古宙时期(超过25亿年前)存在生命的证据。列出了48个据报道含有生物成因叠层石的太古宙沉积物、14个据报道含有40种推定微化石形态类型的此类单元以及13个特别古老(32亿至35亿年)的地质单元的数据,还总结了这些单元现有的有机地球化学数据。这些汇编资料支持了生命存在可追溯至至少35亿年前的观点。
