Late Permian Extinction
The Late Permian Extinction, about 252 million years ago, was the Earth's most severe mass extinction, wiping out roughly 90% of marine and 70% of terrestrial species. It was likely triggered by massive volcanic eruptions in what is now Siberia, releasing huge amounts of gases that caused severe global warming, ocean acidification, and low oxygen levels. These environmental changes disrupted ecosystems, leading to widespread die-offs in both marine and land life. This event significantly reshaped Earth's biological history, paving the way for new life forms to evolve in the aftermath.
