(Phys.org) —A team of European researchers has published a paper in the journal Proceedings of the National Academy of Sciences, offering a possible explanation for the apparent drop in early Earth's oxygen levels following what has come to be known as The Great Oxidation Event. In their paper, the team suggests evidence found in ocean sediments indicates that a sudden addition of carbon into the atmosphere resulted in a relatively quick reduction in oxygen.
