Nickel and urea hints reshape story of early Earth oxygen rise
Tokyo, Japan (SPX) Oct 10, 2025 The appearance of oxygen in Earth's atmosphere was a turning point in the history of our planet, forever transforming the environment and setting the stage for complex life. This event, known as the Great Oxidation Event (GOE), occurred roughly 2.1 to 2.4 billion years ago. Yet, although oxygenic photosynthesis in cyanobacteria is thought to have evolved hundreds of millions of years earlier than this event, oxygen levels in the atmosphere remained low for a prolonged period. Scientists have debated why ... read more |
