Roughly 225 million years ago, the first mammals were creatures you would never have bet on. Small, nocturnal, and overshadowed entirely by dinosaurs, they seemed destined for obscurity. Small mammals, hiding in burrows and feeding on diverse diets, managed to pull through one of the most catastrophic extinction events life has ever known. Their secret ...
Sixty-six million years ago, something ended a reign that had lasted over 160 million years. The non-avian dinosaurs, in all their extraordinary variety, vanished from every continent on Earth. What seems like a settled story turns out, on closer inspection, to be one of the most actively debated questions in all of science. The more ...
Picture a vast, frozen continent where towering mammoths move in herds across open tundra, where giant ground sloths leave trails wide enough to walk through, and where bands of people follow at a careful distance, watching, waiting, surviving. That image is not fiction. It’s the best understanding researchers currently have of how the first humans ...
Picture a world without dinosaurs. No towering sauropods shaking the ground, no ferocious theropods ruling the Mesozoic landscape. That world almost existed, because the rise of dinosaurs wasn’t inevitable. It was the result of hundreds of millions of years of incremental, sometimes brutal, evolutionary change that began with small, unassuming creatures crawling through the forests ...
You might picture the age of dinosaurs as a story dominated by thundering herds on land and feathered predators in the sky. The ocean, though, tells a different story. During the Mesozoic Era, stretching roughly from 252 to 66 million years ago, the seas were ruled by reptiles so specialized and so deadly that no ...
For most of the twentieth century, the story of the first North Americans seemed settled. Humans crossed a land bridge from Siberia roughly thirteen thousand years ago, spread across the continent, and left behind a distinctive set of stone tools. Tidy, teachable, and reassuringly final. Except it wasn’t. Archaeological discoveries throughout the Americas are pushing ...
Dinosaurs have been extinct for roughly 66 million years, yet in 2026 we understand them better than at any point in history. Not because we’ve found more bones, but because the tools scientists use to study those bones have transformed beyond recognition. The old image of a paleontologist with a whisk brush and a magnifying ...
Picture a creature with a neck so long it made up nearly half its entire body length, four powerful wings instead of legs, and eyes that may have been adapted to see in the darkness of deep ocean water. No, it’s not science fiction. It swam real prehistoric seas for roughly 140 million years, and ...
There’s something unmistakable about a person who just knows. They walk into a room and immediately sense something is off. They size someone up in sixty seconds and rarely get it wrong. It’s not magic, and it’s not luck. It’s instinct, raw and deeply wired. The Allosaurus was one of the most formidable apex predators ...
There’s something quietly astonishing about holding the idea that, tens of thousands of years before writing, cities, or even agriculture, people were making art about the creatures they lived alongside. They painted them on cave walls deep underground, carved them from bone and ivory, and shaped them from clay. These weren’t idle hobbies. The animals ...
