Why do beaches today have seashells from clams and snails instead of brachiopods? A new study suggests the answer lies in Earth's greatest mass extinction, when warming oceans and falling oxygen levels wiped out animals that couldn't adapt. Species with body plans and metabolisms better suited to the changing conditions survived and went on to dominate the seas, offering a glimpse of how modern marine life could respond to climate change.
Researchers Confirm The Cause Of Earth’s Biggest Mass Extinction
A new Stanford-led study offers the clearest picture yet of how some ocean life survived our planet’s biggest mass extinction while most animals did not. About 252 million years ago, 96% of marine species and 70% of land animals died off during the Permian–Triassic extinction event, known as the “Great Dying.” Not all branches of the evolutionary tree were affected evenly, however. In the ancient oceans, the extinction wiped out nearly all brach…
Recent research by a team from Stanford University suggests the causes of the largest mass extinction in the history of our planet. Approximately 252 million years ago, during the Permian-Triassic extinction, as many as 96 percent of marine species and 70 percent of land animals vanished from the Earth's surface. The researchers' findings, published in the journal Proceedings of the National Academy of Sciences, provide a better understanding of…
