The researchers compared their model to past mass extinctions captured in the fossil record. They built on their earlier work that linked the geographic pattern of Earth's deadliest extinction event — the end-Permian extinction about 250 million years ago — to its underlying drivers: climate warming and oxygen loss from the oceans.Approximately 250 million years ago, the biggest extinction event in the history of the Earth (in terms of the number of species that disappeared) took place at the end of the Permian period.
