Sulfur isotopes can serve as tracers of atmospheric oxygen, and new data collected from the present-day atmosphere in China by an international team of researchers, led by the University of California San Diego, indicate remarkable similarity to the isotopic footprint found in ancient rocks. This opens up new interpretations of the Archean Period's sulfur isotope sedimentary signature--a proxy for the origins and evolution of atmospheric oxygen and early life on Earth.
