Mid-Devonian ocean oxygenation enabled the expansion of animals into deeper-water habitats Open
The oxygenation history of Earth’s surface environments has had a profound influence on the ecology and evolution of metazoan life. It was traditionally thought that the Neoproterozoic Oxygenation Event enabled the origin of animals in mar…

Resurrected nitrogenases recapitulate canonical N-isotope biosignatures over two billion years Open
SUMMARY Nitrogen isotope fractionation (ε 15 N) in sedimentary rocks has provided evidence for biological nitrogen fixation, and thus primary productivity, on the early Earth. However, the extent to which molecular evolution has influenced…

Carbon Isotope Fractionation by Cyanobacteria under light-limiting conditions Open
The evolution of oxygenic photosynthesis and the resulting accumulation of oxygen in the atmosphere, known as the Great Oxidation Event (GOE), is one of the most prominent transitions in Earth history. While cyanobacteria are thought to be…
