When the ancestors of modern humans left Africa 50,000 years ago they met the Neandertals. In this encounter, the Neandertal population contributed around two percent of the genome to present day non-African populations. A collaboration of scientists from Aarhus University in Denmark, deCODE Genetics in Iceland, and the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, have conducted the most comprehensive study to date using data obtained from 27,566 Icelanders, to figure out which parts of our genomes contain Neandertal DNA and what role it plays in modern humans. Every person of non-African decent shares around two percent of...

Stone artifacts painstakingly shaped into spheres were part of the daily lives of early humans for more than two million years. They have been unearthed by archaeologists in East Africa, humanity's ancestral home, and they litter prehistoric sites across Eurasia from the Middle East to China and India. Yet experts have been puzzled by their function since the early days of research into our evolutionary history. Now, an international team of archaeologists led by Tel Aviv University archaeologist researcher Ella Assaf, has produced evidence that these enigmatic artifacts were used for a very specific purpose: breaking the bones of large...

Griffith University scientists have led an international team to date the skull of an early human found in Africa, potentially upending human evolution knowledge with their discovery. The Broken Hill (Kabwe 1) skull is one of the best-preserved fossils of the early human species Homo heidelbergensis and was estimated to be about 500,000 years old... Discovered in 1921 by miners in Zambia, the Broken Hill remains have been difficult to date due to their haphazard recovery and the site being completely destroyed by quarrying. Using radiometric dating methods, Professor Grün’s analyses now puts the skull at a relatively young date,...

When it comes to deciphering our ancient family tree, DNA from fossils is the new gold standard. But after about half a million years, even the best-preserved DNA degrades into illegibility, leaving the story of our early evolution shrouded in mystery. A new study of proteins taken from the tooth of an enigmatic human ancestor reveals their rough place in the family tree -- and shows how ancient proteins can push beyond the limits of DNA. The new study is "a landmark paper," says Mark Collard, an archaeologist at Simon Fraser University who wasn't involved with the work. "Ancient protein...

EVeryone knows the standard explanation of evolution but the rapid jump from Homo Erectus to Homo Sapiens has no satisfactory answers. A more radical interpretation of these events involves the same animals, dung, and plants but also includes psychedelic drugs. In 1992, ethnobotanist and psychedelics advocate Terence McKenna argued in the book Food of the Gods that what enabled Homo erectus to evolve into Homo sapiens was its encounter with magic mushrooms and psilocybin, the psychedelic compound within them, on that evolutionary journey. He called this the Stoned Ape Hypothesis. McKenna posited that psilocybin caused the primitive brain’s information-processing capabilities...

A Homo erectus skullcap found northwest of Johannesburg in South Africa has been identified as the oldest to date, in research published in Science. The hominin is a direct ancestor of modern humans, experienced a changing climate, and moved out of Africa into other continents. The discovery of DNH 134 pushes the possible origin of Homo erectus back between 150,000 and 200,000 years.

The rolling hills...

Neanderthals are often depicted as having straight spines and poor posture. However, these prehistoric humans were more similar to us than many assume. University of Zurich researchers have shown that Neanderthals walked upright just like modern humans - thanks to a virtual reconstruction of the pelvis and spine of a very well-preserved Neanderthal skeleton found in France... Since the 1950s, scientists have known that the image of the Neanderthal as a hunched over caveman is not an accurate one. Their similarities to ourselves - both in evolutionary and behavioral terms - have also long been known, but in recent years...

The prestigious international journal Quaternary Science Reviews has just published a paper which has involved the participation of Gibraltarian scientists from the Gibraltar National Museum alongside colleagues from Spain, Portugal and Japan. The results which have been published come from an area of the Catalan Bay Sand Dune. This work started ten years ago, when the first dates using the OSL method were obtained. It is then that the first traces of footprints left by vertebrates were found. In subsequent years the successive natural collapse of sand has revealed further material and has permitted a detailed study including new dates....

Just like the modern platypus, this 250-million-year-old, Triassic-age marine reptile likely used its cartilaginous bill to discover and seize its next meal, a new study finds. "This animal had unusually small eyes for the body, only rivaled by some living animals that rely on senses other than vision and feed in the dusk or darkness — for example some shrews, badgers and the duck-billed platypus," said study lead researcher Ryosuke Motani, a paleobiologist at the University of California, Davis. "So, it most likely used tactile senses [with its] platypus-like bill to detect prey in the dusk or darkness." ..." Previously,...

Paleoanthropology Division Smithsonian Institute 207 Pennsylvania Avenue Washington, DC 20078 Dear Sir: Thank you for your latest submission to the Institute, labeled “ 211-D, layer seven, next to the clothesline post . Hominid skull .” We have given this specimen a careful and detailed examination, and regret to inform you that we disagree with your theory that it represents “conclusive proof of the presence of Early Man in Oklahoma County two million years ago. .” Rather, it appears that what you have found is the head of a Barbie doll, of the variety one of our staff, who has small...

One hundred million years ago, the sky was filled with birds unlike those seen today, many with long, streamerlike tail feathers. Now, paleontologists have found examples of these paired feathers preserved in exquisite detail in 31 pieces of Cretaceous amber from Myanmar. The rare 3D preservation reveals the feathers’ structure is completely different from that of modern feathers—and hints that they may have been defensive decoys to foil predators. Such tail streamers—in some cases longer than the bodies—have been observed in early bird fossils from China for several decades, in particular, the 125-million-year-old Confuciusornis sanctus. They may also be present...

About 2.6 million years ago, an oddly bright light arrived in the prehistoric sky and lingered there for weeks or months. It was a supernova some 150 light years away from Earth. Within a few hundred years, long after the strange light in the sky had dwindled, a tsunami of cosmic energy from that same shattering star explosion could have reached our planet and pummeled the atmosphere, touching off climate change and triggering mass extinctions of large ocean animals, including a shark species that was the size of a school bus. The effects of such a supernova—and possibly more than...

A giant rhino that may have been the origin of the unicorn myth survived until at least 39,000 years ago - much longer than previously thought. Known as the Siberian unicorn, the animal had a long horn on its nose, and roamed the grasslands of Eurasia. New evidence shows the hefty beast may have eventually died out because it was such a picky eater. Scientists say knowing more about the animal's extinction could help save the remaining rhinos on the planet. Rhinos are in particular danger of extinction because they are very picky about their habitat, said Prof Adrian Lister...

Imagine if you crossed a rhino with a giant turtle and then supersized the result: You might get something like Lisowicia bojani, a newly discovered Triassic mammal cousin that had a body shaped like a rhinoceros, a beak like a turtle, and weighed as much as an African elephant, about 9 tons. Paleontologists say this startling creature offers a new view of the dawn of the age of the dinosaurs. "Who would have ever thought that there were giant, elephant-sized mammal cousins living alongside some of the very first dinosaurs?" marvels Stephen Brusatte, a vertebrate paleontologist at The University of...

A new species of sauropod dinosaur that stretched 39 feet (12 m) from head to tail has been unearthed in Patagonia, ArgentinaDubbed Lavocatisaurus agrioensis, the new dinosaur is thought to have lived approximately 110 million years ago (Cretaceous period).The creature was a type of sauropod, a group of huge plant-eating dinosaurs that includes the largest animals ever to walk the Earth.One adult and two immature specimens of Lavocatisaurus agrioensis were recovered near the locality of Agrio del Medio, a small town in the central part of the province of Neuquén, Patagonia.“We found most of the skull bones of Lavocatisaurus agrioensis:...

An international team of scientists has completed the first 3D virtual reconstruction of the ribcage of the most complete Neandertal skeleton unearthed to date, potentially shedding new light on how this ancient human moved and breathed. The team, which included researchers from universities in Spain, Israel, and the United States, including the University of Washington, focused on the thorax -- the area of the body containing the rib cage and upper spine, which forms a cavity to house the heart and lungs. Using CT scans of fossils from an approximately 60,000-year-old male skeleton known as Kebara 2, researchers were able...

We now know what the missing teeth would have looked like at the front of this jaw. Eden, Janine and Jim/CC BY 2.0Until this week, Pachycephalosaurus seemed like a friendly neighborhood herbivore. The scariest thing about these dinosaurs, which have been frequently depicted placidly munching on greenery, was the unique architecture of their skulls: domed, sloping, pointy around the edges, and 10 inches thick. They might have butted heads, but that didn’t make them seem dangerous, exactly.But now, new research presented at a Society of Vertebrate Paleontology conference in Albuquerque, New Mexico, raises the specter that Pachycephalosaurus was a...

The 28 footprints capture an early reptile-like creature’s unusual diagonal gait (Courtesy of Stephen Rowland) Some 310 million years ago, a reptile-like creature with an unusual gait roamed the sandy expanses of the Grand Canyon, leaving a trail of 28 footprints that can still be seen today. As Michael Greshko reports for National Geographic, these unusually well-preserved markers represent the national park’s oldest footfalls—and, if additional analysis links the early reptile to one that left a similar set of prints in Scotland roughly 299 million years ago, the tracks may even earn the distinction of being the oldest of their...

The Three Supernovas By Philip Cottraux Atheists used to believe the universe was eternally pre-existing and static. By rejecting the biblical creation account, they couldn’t accept the idea of a universe that had a beginning. Bertrand Russell, Charles Darwin, and at one time even Einstein labored under this philosophy. The idea of the whole universe condensed to a small state whose expansion was triggered by a colossal explosion was first proposed by a Catholic priest, Georges LeMaitres. The idea seemed so preposterous that astronomer Fred Hoyle first coined the phrase “big bang” as a term of ridicule. But two years...
