Extinction event

An extinction event is a significant and widespread reduction in Earth's biological diversity, where many species across various groups disappear in a relatively short geological period. These events are typically caused by major environmental changes, such as asteroid impacts, volcanic activity, climate shifts, or other catastrophic forces that disrupt ecosystems. While some species survive and adapt, a large percentage of life forms become extinct, altering the course of evolution. Extinction events have occurred multiple times in Earth's history, shaping the diversity of life we see today and highlighting the dynamic, ever-changing nature of our planet.
