Plankton Key to Origin of Earth's First Breathable Atmosphere
February 21, 2011
Researchers studying the origin of Earth's first breathable atmosphere have zeroed in on the major role played by some very unassuming creatures: plankton. In a paper to appear in the online early edition of the Proceedings of the National Academy of Sciences, Ohio State University researcher Matthew Saltzman and his colleagues show how plankton provided a critical link between the atmosphere and chemical isotopes stored in rocks 500 million years ago.
