From the Cambrian Explosion to the Great Dying

The video explores the Paleozoic era, a critical period in Earth's history from 541 to 252 million years ago. It highlights the Cambrian explosion, which introduced major animal groups and adaptations, and the subsequent periods marked by biodiversification and mass extinctions. The Ordovician and Silurian periods saw significant evolutionary changes, while the Devonian period marked the rise of fish and the first land ecosystems. The Carboniferous period introduced amniotes, leading to the formation of Pangaea. The era ended with the Permian-Triassic extinction, nearly wiping out life on Earth.
