For half a billion years, the planet has been keeping a secret written in iron and air: Earth's magnetic field and its atmospheric oxygen have risen and fallen together, as if guided by a single, unseen hand. NASA scientists have now read that record carefully, tracing the parallel rhythms of deep-Earth dynamics and surface life conditions back to the Cambrian explosion. The finding invites a humbling possibility — that the molten interior of our world and the breath of its creatures are not separate stories, but expressions of the same planetary logic.
