The Archean is the period of geological time between 3.8 and 2.5 billion years ago when life is thought to have emerged on Earth. Traces of Archean life are preserved in rare, fragmentary, and often highly altered rock sequences. Morphological evidence for Archean life is provided by microfossils, microborings, stromatolites, and wrinkle mats. Chemical evidence for life is recorded by stable isotope ratios of C and S especially. These different biosignatures are yet to provide a consistent and complete picture of early Archean ecosystems, and there is currently little scientific consensus about when and where life first emerged on Earth. Refining our understanding of microbial biosignatures in the Archean rock record is essential to designing strategies for seeking life elsewhere in our universe and for ratifying this evidence.
