Stanford-Led Research Shows Huge Die-Off in Ancient Biosphere

A mass extinction killed most life on Earth.

When significant oxygen entered the atmosphere, ancient life multiplied. But after a few hundred million years, Earth’s oxygen plummeted, resulting in a die-off likely greater than the extinction of the dinosaurs. (Image: Malcolm Hodgskiss)
