Research has uncovered important new insights into the evolution of oxygen, carbon, and other vital elements over the entire history of Earth – and it could help assess which other planets can develop life, ranging from plants to animals and humans.
The study, published today in Nature Geoscience and led by a researcher at the University of Bristol, reveals for the first time how the build up of carbon-rich rocks has accelerated oxygen production and its release into the atmosphere.
Until now the exact nature of how the atmosphere became oxygen-rich has long eluded scientists and generated conflicting explanations.
As carbon dioxide is steadily emitted by volcanoes, it ends up entering the ocean and forming rocks like limestone.
As global stocks of these rocks build up t...
