Summary:
- This article discusses a surprising finding that challenges the traditional understanding of mass extinctions in Earth's history.
- Researchers have discovered that the Permian-Triassic mass extinction, which occurred around 252 million years ago, was not caused by a single catastrophic event, but rather a series of smaller events over a longer period of time.
- This discovery changes the way scientists view mass extinctions, suggesting they may be more complex and gradual processes rather than sudden, dramatic events.
