Extinction events are significant occurrences in Earth's history where a substantial number of species die out in a relatively short period. These events can be caused by various factors, including climate change, volcanic eruptions, and asteroid impacts. One of the most famous extinction events is the Cretaceous-Paleogene Extinction, which led to the demise of the dinosaurs around 66 million years ago. The consequences of extinction events can reshape ecosystems and lead to the emergence of new species. Understanding these events helps scientists learn about biodiversity and the resilience of life on Earth. The study of extinction events is crucial for conservation efforts today, as it provides insights into how current species might respond to ongoing environmental changes.
