An illustration of the Devonian period fish, Dunkleosteus, preying on eurypterids (sea scorpions), which in turn were feeding on the smaller trilobites. Depleting oxygen and rising hydrogen sulfide ...

A million years ago, the interglacial periods were relatively cool. Then, 430,000 years ago, they switched to milder conditions that resemble our own. A new paper looks at what drove this change.
