Researchers have discovered new evidence to suggest that the origins of mummification started in ancient Egypt 1,500 years earlier than previously thought. The findings of an 11-year study push back the origins of a central and vital facet of ancient Egyptian culture by over a millennium.
All life on Earth came from one common ancestor– a single-celled organism– but what it looked like, how it lived and how it evolved into today’s modern cells is a four-billion-year-old mystery being solved by researchers using mathematical modeling. Findings suggest for the first time that life’s last universal common ancestor had a “leaky” membrane, which helps scientists answer two of biology’s biggest questions.
The Jurassic and Cretaceous periods were the golden age of dinosaurs, during which the prehistoric giants roamed the Earth for nearly 135 million years. Paleontologists have unearthed numerous fossils from these periods, suggesting that dinosaurs were abundant throughout the world. But new evidence raises questions about when dinosaurs evolved in North America.
During a four-year excavation of an Etruscan well at the ancient Italian settlement of Cetamura del Chianti, a team unearthed artifacts spanning more than 15 centuries of Etruscan, Roman and medieval civilization in Tuscany.
In October 2004, an excavation found fragmentary skeletal remains of what was thought to be a previously unknown species of human. Now, researchers say the bones do not represent a new species: it’s the skeleton of a developmentally abnormal human with features most consistent with a diagnosis of Down syndrome.
A study of 1,400 ancient and modern human skulls suggests that a reduction in testosterone hormone levels accompanied the development of cooperation, complex communication and modern culture some 50,000 years ago.
New research shows that more than four billion years ago, the surface of Earth was heavily reprocessed – or mixed, buried and melted – as a result of giant asteroid impacts. A new terrestrial bombardment model based on existing lunar and terrestrial data sheds light on the role asteroid bombardments played in the geological evolution of the uppermost layers of the Hadean Earth.
Scientists have mapped how a group of fearsome, massive dinosaurs evolved and shrank to the likes of robins and hummingbirds. Comparing fossils of 120 different species and 1,500 skeletal features, especially thigh bones, researchers constructed a detailed family tree for the class of two-legged meat-eaters called theropods.
Researchers said this week that a vessel unearthed four years ago at the World Trade Center site in Lower Manhattan was made from wood cut around the year 1773 — two years before the start of the war and three years before the signing of the Declaration of Independence.
Quantifying and transforming the history of culture into visual representation isn't easy. There are thousands of individual stories across millennia to consider, and some historical conditions are nearly impossible to measure. The challenge brought together a team of network and complexity scientists to create a big picture of European and North American cultural history.
Scientists are searching through a massive collection of 20-million-year-old amber found in the Dominican Republic more than 50 years ago, and the effort is yielding fresh insights into ancient tropical insects and the world they inhabited.
Ancient remains have confirmed that the face and jaw evolved before the rest of the skull in Neanderthals and early human ancestors. Research conducted at the Sima de los Huesos (Pit of the Bones) archaeological site in northern Spain has confirmed a much-debated hypothesis on how our early human ancestors evolved.
Dinosaurs might have survived the asteroid strike that wiped them out if it had taken place slightly earlier or later in history, scientists say. A fresh study using up-to-date fossil records and improved analytical tools has helped palaeontologists to build a new narrative of the prehistoric creatures' demise, some 66 million years ago.
For the first time in more than 30 years, paleontologists are about to revisit one of North America's most remarkable troves of late Pleistocene fossils: the bones of tens of thousands of animals piled at least 30 feet deep at the bottom of a sinkhole-type cave.
Research shows ancient mammoths and mastodons enjoyed the now-Greater Cincinnati area so much they likely were year-round residents and not nomadic migrants as previously thought. Findings indicate each species kept to separate areas based on availability of favored foods at the southern edge of the Last Glacial Maximum's major ice sheet.
Cancer has left its “footprint” on our evolution, according to a study that examined how the relics of ancient viruses are preserved in the genomes of 38 mammal species.
Paleontologists have identified the exquisitely preserved brain in the fossil of one of the world's first known predators that lived in the Lower Cambrian, about 520 million years ago. The discovery revealed a brain that is surprisingly simple and less complex than those known from fossils of some of the animal's prey.
European researchers have recovered a genome of the bacterium Brucella melitensis from a 700-year-old skeleton found in the ruins of a medieval Italian village.
A closer look based on micro-CT scans at a 100,000-year-old human skull that was recovered 35 years ago in China revealed that it had an inner ear formation that was thought only to have occurred in Neanderthals. In comparison, none of the three other archaic human skulls analyzed from different parts of China had this type of inner ear.
An ancient token-based recording system from before the dawn of history was rendered obsolete by the birth of writing, according to popular wisdom. But now, latest excavations show that, in fact, these clay tokens were integral to administrative functions right across the Assyrian empire– millennia after this system was believed to have vanished.
The XMM-Newton observatory has helped to uncover how the Universe’s first stars ended their lives in giant explosions.
A stunning video based on fossils of a 410-million-year-old arachnid– one of the first predators on land– recreates the animal walking. Scientists used the fossils– thin slices of rock showing the animal’s cross-section– to work out the range of motion in the limbs of this ancient, extinct early relative of spiders.
A new study shows that some shark species may be able to cope with the rising salinity of Arctic waters that may come with rising temperatures. Roughly 53 to 38 million years ago, the Arctic was similar to a huge temperate forest with brackish water, home to a variety of animal life. A new study of shark teeth taken from a coastal Arctic Ocean site has expanded the understanding of Eocene marine life.
The reexamination of a sparrow-sized fossil from China challenges the commonly held belief that birds evolved from ground-dwelling theropod dinosaurs that gained the ability to fly. The birdlike fossil is actually not a dinosaur, as previously thought, but much rather the remains of a tiny tree-climbing animal that could glide.
CT scans of two newborn woolly mammoths recovered from the Siberian Arctic are revealing previously inaccessible details about the early development of prehistoric pachyderms. In addition, the X-ray images show that both creatures died from suffocation after inhaling mud.
