Life Without Light – Traces Of Chemosynthesis In Microbially-Formed Minerals And Rocks

Approximately 4 billion years ago, the first life on Earth used energy from the oxidation of reduced chemical compounds – a mode of biomass production referred to as chemosynthesis. Photosynthesis, particularly in the form of oxygenic photosynthesis, soon began to be the dominant mode of primary production on Earth after its advent. However, ecosystems still
