Researchers at MIT have found evidence that some early life forms began using oxygen hundreds of millions of years before it accumulated in Earth's atmosphere. The study traces a key oxygen-processing enzyme to the Mesoarchean era, suggesting microbes consumed oxygen produced by cyanobacteria. This discovery challenges previous understandings of aerobic respiration's timeline.
