In the last 500 million years, there have been five major mass extinctions, often referred to as the "Big Five." These include the Late Ordovician, Late Devonian, Permian-Triassic, Late Triassic, and Cretaceous-Paleogene extinctions. Each event resulted in the significant loss of biodiversity and had profound impacts on Earth's ecosystems. Additionally, some scientists suggest that we may be in the midst of a sixth mass extinction driven by human activities.
