Scientists finally solved the mystery of Earth's greatest mass extinction
Quick Summary
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.
