What caused the most extinction-level change?
- Around 252 million years ago, the end of the Permian epoch was marked by the greatest extinction in Earth's history.
- Our world was home to a variety of flora and creatures long before the emergence of dinosaurs, most of which were wiped off by a series of enormous volcanic eruptions in Siberia.
