Around 250 million years ago, one of Earth’s largest known volcanic events set off The Great Dying: the planet’s worst mass extinction event. The eruptions spewed large amounts of greenhouse gases into the atmosphere, temperatures rose globally and oxygen in the oceans dropped. 

And while the vast majority of species went extinct, some survived. Scientists like paleophysiology graduate student Kemi Ashing-Giwa want to know why, because lessons about the survivors of The Great Dying could inform today’s scientists on how to curb extinctions today.
