scientists have come across evidence that suggests oxygen production began in Earth's oceans at least 100 million years before the "Great Oxidation Event" (GOE).When the GOE happened around 2.4 billion years ago, the Earth's atmosphere underwent a dramatic change, with oxygen levels rising sharply.The oxygen spike marks an important milestone in Earth's history, the transformation from an oxygen-poor...
