The Great Dying was longer on land
Earth’s biggest mass extinction took ten times longer on land than in oceans.
New researchpublishedin the journalPNAShas found that, while life in the ocean rapidly disappeared during the Great Dying at the end-Permian mass extinction, the loss of life on land was a much more drawn-out affair.
The Earth has suffered fivemass extinction eventsthroughout its history, each permanently altering life’s evolutionary trajectory. But the most devastating was the end-Permianevent, 252 million years ago.
Nicknamed the “Great Dying”, it is thought to have been triggered by catastrophic volcanic eruptions, resulting in dramatic environmental changes – including a runaway greenhouse effect and ocean acidification – that wiped out 95% of both land and ocean species...
