Source: University of Missouri In a recent study, researchers studied ancient reefs built by sponge-like creatures called archaeocyathids in Nevada, 514 million years ago. They found that early reefs did not appear to boost biodiversity in the same way as modern coral reefs do. Modern coral reefs are known as biodiversity hotspots, supporting the entire…
More than 500 million years before Matt Groening and “The Simpsons” introduced us to Blinky, a mutated fish with an extra eye swimming through Springfield’s Old Fishin’ Hole, a three-eyed predator chased prey through seas of the Cambrian Period. Once it caught its quarry, a pair of spine-covered grasping claws and a circular mouth covered…
For more than a decade, scientists have chased the idea of reviving extinct species, a process sometimes called de-extinction. Now, a company called Colossal Biosciences appears to have done it, or something close, with the dire wolf, a giant, extinct species made famous by the television series “Game of Thrones.” In 2021, a separate team…
Ralph Holloway, an anthropologist who pioneered the idea that changes in brain structure, and not just size, were critical in the evolution of humans, died on March 12 at his home in Manhattan. He was 90. His death was announced by Columbia University’s anthropology department, where he taught for nearly 50 years. Mr. Holloway’s contrarian…
Ten years ago, this was just a big hole in the ground behind a Lowe’s home improvement store in southern New Jersey, an unlikely place to find what might be one of the world’s most important fossil sites. But 66 million years ago, tantalizingly close in time to when the dinosaurs went extinct, a multitude…
Humans, unlike most other species, have a knack for making tools. Six million years ago, our apelike ancestors probably smashed nuts with rocks or caught termites with sticks. Around 3.3 million years ago, hominins began using flakes of stone, perhaps to cut flesh from carcasses or chop plants. And by 1.5 million years ago, they…
For generations, scientists looked to the East African savanna as the birthplace of our species. But recently some researchers have put forward a different history: Homo sapiens evolved across the entire continent over the past several hundred thousand years. If this Africa-wide theory were true, then early humans must have figured out how to live…
Above the shores of prehistoric seas and lakes, pterosaurs roamed the skies. They were feathered creatures that ranged in size from pigeons to planes, and the first vertebrates known to have been able to fly. And for millions of years, they had long tails ending in a prominent flap of skin called a vane. Paleontologists…
With serpentine necks, flippers and a mouth full of needle-sharp teeth, plesiosaurs have captured imaginations since paleontologists uncovered the first specimen more than two centuries ago. Their skeletal anatomy is well documented, but their external appearance has largely remained a mystery. Now researchers have conducted the first detailed analysis of plesiosaur soft tissue, offering a…
It’s taken decades, but scientists may have finally found Earth’s first fowl. It started in 1993 on Vega Island, a frigid, windswept rock off the Antarctic Peninsula. A mostly headless skeleton of a loon-size diving bird emerged from rocks that, at 68 million years old, predated the dinosaur extinction. The species, which scientists named Vegavis…
