Our window into the Earth's ancient microbial past is narrow and obscured by missing data. However, we can glean information about ancient microbial ecosystems using fossil lipids (biomarkers) that are extracted from billion-year-old sedimentary rocks. In this Opinion article, we describe how environmental genomics and related methodologies will give molecular fossil research a boost, by increasing our knowledge about how evolutionary innovations in microorganisms have changed the surface of planet Earth.
我们了解地球古代微生物历史的窗口很窄，且因数据缺失而模糊不清。然而，我们可以利用从数十亿年前的沉积岩中提取的化石脂质（生物标志物）来收集有关古代微生物生态系统的信息。在这篇观点文章中，我们描述了环境基因组学及相关方法将如何通过增进我们对微生物进化创新如何改变地球表面的了解，推动分子化石研究。
