Viking Age burial of chieftain with 'enormous power' found in Denmark — and he may have served Harald Bluetooth
Archaeologists in Denmark have discovered 30 Viking Age graves likely of an elite family that may have served under Harald Bluetooth, the famed king of Denmark and Norway who ruled during the 10th century. The remarkable graves contained coins, pearls and ceramics, according to a translated statement from Moesgaard Museum, which ran the excavation.
Burials from the Viking Age (A.D. 793 to 1066) are not uncovered very often, Liv Stidsing Reher-Langberg, an archaeologist at the museum and excavation leader at the burial site, told Live Science in an email. Most graves from this time are found with few or no grave goods, she added. These newly unearthed burials in Lisbjerg, near Aarhus, however, came with an unusual number of lavish items, suggesting that the people buried in them were prosperous and of high status.
"The burial site here at Lisbjerg is quite special," Reher-Langberg said.
The archaeologists had previously found a chieftain's farm nearby, so they associated these graves with him. This nobleman would have been part of the aristocracy at the time, just below King Bluetooth in the social hierarchy. Bluetooth was extremely influential, joining the tribes of the region into one kingdom — which is why the technology that unites electronic devices is named after him.
"The chieftain in Lisbjerg had enormous power — economically, politically, religiously and socially," Reher-Langberg said.
The graves, which likely date to the late 900s, are of varied size and extravagance. This disparity could indicate a mix of social statuses among the buried, possibly the chieftain's family and their enslaved people, the archaeologists said in the statement.

The "most exceptional" grave was a woman's casket, Naja Kjærgård Laursen, a spokesperson at Moesgaard Museum, said in an email. The coffin "had the finest fittings, rivets, and an advanced locking mechanism," Reher-Langberg added.

Researchers used X-ray imaging to see which grave goods were hidden in the newly discovered burial site in Lisbjerg, Denmark.
Using X-ray imaging, the team found that the casket contained ornate personal belongings, including jewelry, a needle and an elegant pair of scissors. They found more goods in other graves, as well as the teeth and bones of some of the buried individuals.
Preliminary investigations in the area indicated there were traces of the pre-Roman Iron Age (500 to 1 B.C.). But even after finding the chieftain's farm nearby, they didn't have any reason to anticipate the Viking Age graves were there, too.
It was "a huge surprise," Reher-Langberg said. "We simply had no expectations of finding graves."

Now that the excavations are almost complete, the team has sent many of the objects to be analyzed and preserved by the museum's Natural Science and Conservation department, Kjærgård Laursen told Live Science.
The human remains, wood and soil from the excavation will also be analyzed. "Hopefully, all this will lead to even more studies" in the area, Reher-Langberg said.
These artifacts will go on display at Moesgaard Museum in Denmark this summer.

Fossils show two types of ancient human ancestors lived at the same place and time. One was possibly an unknown species
Ancient, fossilized teeth, uncovered during a decades-long archaeology project in northeastern Ethiopia, indicate that two different kinds of hominins, or human ancestors, lived in the same place between 2.6 million and 2.8 million years ago — and one of them may be a previously unknown species. The discovery provides a new glimpse into the complex web of human evolution. Ten of the teeth, found between 2018 and 2020, belong to the genus Australopithecus, an ancient human relative. Meanwhile, three teeth, found in 2015, belong to the genus Homo, which includes modern humans, or Homo sapiens. The results were published Wednesday in the journal Nature. Such an overlapping of two hominins in the fossil record is rare, which had previously led scientists to believe that Homo appeared after Australopithecus, rather than the two being contemporaries. Australopithecus species walked upright much like modern humans, but had relatively small brains, closer in size to those of apes. The emergence of Homo species, with their larger brains, is easy for people today to view as some sort of evolutionary upgrade on a path to modern humanity. But the coexistence of the two demonstrates that hominins developed, and lived, in multiple varieties at once. 'This new research shows that the image many of us have in our minds of an ape to a Neanderthal to a modern human is not correct — evolution doesn't work like that,' said study coauthor Kaye Reed, research scientist and president's professor emerita at the Institute of Human Origins and emeritus professor at the School of Human Evolution and Social Change at Arizona State University, via email. 'Here we have two hominin species that are together. And human evolution is not linear, it's a bushy tree, there are life forms that go extinct.' Since 2002, Reed has been a codirector of the Ledi-Geraru Research Project, which is focused, in part, on searching for evidence of early Homo species. In 2015, the team announced the discovery of the oldest known Homo jawbone at 2.8 million years old. It has also searched for later evidence of Australopithecus afarensis, which first appeared 3.9 million years ago, but there is no sign of these ancient human relatives in the fossil record after 2.95 million years ago — suggesting they went extinct before Homo's first appearance. Australopithecus afarensis is best represented by the famed fossilized remains of Lucy, discovered in 1974 in Ethiopia. Lucy was shorter than an average human, reaching about 3.3 feet (1 meter) in height, had an apelike face and a brain about one-third the size of a human brain. Her fossil showcased a mixture of humanlike and apelike traits and provided proof that ancient human relatives walked upright 3.2 million years ago. When the team discovered the Australopithecus teeth during two separate digs in 2018 and 2020, it compared them with species such as afarensis and another hominin group known as garhi, but they didn't match up. Instead, the scientists believe the teeth belong to a previously unknown species of Australopithecus that walked the Earth after Lucy — and alongside an early Homo species. 'Once we found Homo, I thought that was all we would find, and then one day on survey, we found the Australopithecus teeth,' Reed said. 'What is most important, is that it shows again, that human evolution is not linear. There were species that went extinct; some were better adapted than others, and others interbred with us — we know this for Neanderthals for sure. So anytime that we have another piece to the puzzle of where we came from, it is important.' Cracks in Earth's surface The teeth were found in Ethiopia's Afar region, a key place for researchers seeking answers about human evolution. A variety of preserved fossils have been found there as well as some of the earliest stone tools, Reed said. The Afar region is an active rifting environment — the tectonic plates beneath its earth are actively pulling apart and exposing older layers of sediment that shed light on almost 5 million years of evolution, Reed said. 'The continent is quite literally unzipping there, which creates a lot of volcanism and tectonics,' said study coauthor Christopher Campisano, associate director and associate professor at the Institute of Human Origins and associate professor at the School of Human Evolution and Social Change at Arizona State, in a video the school released. 'At 2 1⁄2, 3 million years ago, these volcanoes spewed out ash that contain crystals called feldspars that allow us to date the eruptions that were happening on the landscape when they're deposited.' The Australopithecus teeth documented in the new study were dated to 2.63 million years ago, while the Homo teeth are from 2.59 million and 2.78 million years ago. But the team is cautious about identifying a species for any of the teeth until it has more data and more fossils. 'We know what the teeth and mandible of the earliest Homo look like, but that's it,' said Brian Villmoare, lead study author and associate professor in the department of anthropology at the University of Nevada, Las Vegas, in a statement. 'This emphasizes the critical importance of finding additional fossils to understand the differences between Australopithecus and Homo, and potentially how they were able to overlap in the fossil record at the same location.' The Australopithecus teeth broadly resembled those of the afarensis species in contour and the size of the molars, but features of the cusps and canine teeth had not been previously seen in afarensis or garhi teeth, Villmoare said. The teeth were also different in shape than those of any Homo species, or of the ancient human relative Paranthropus, known for its large teeth and chewing muscles. 'Obviously these are only teeth,' Villmoare said, 'but we are continuing field work in the hopes of recovering other parts of the anatomy that might increase resolution on the taxonomy.' Even just finding the teeth was a complicated task, according to Campisano. 'You're looking at little teeth, quite literally, individual teeth that look just like a lot of other of the little pebbles spread on the landscape,' he said in the video. 'And so, we have a great team of local Afars that are excellent fossil hunters. They've seen these things their entire lives walking around the landscape.' A blip for evolution The new study is important because it provides insight into a time frame from 3 million to 2 million years ago, a mysterious period in human evolutionary studies, said Dr. Stephanie Melillo, paleoanthropologist and assistant professor at Mercyhurst University in Pennsylvania. Melillo was not involved in this research, but she has participated in the Woranso-Mille Paleontological Research Project in the Afar Triangle of Ethiopia. Part of the problem in learning about this stretch of prehistory is how ancient layers of dirt were deposited over the course of history in eastern Africa. 'Erosion in rivers and lakes were at a low level and only a little bit of dirt was deposited in the Afar,' Melillo wrote in an email. 'That deposited dirt contains the fossils — of our ancestors and all the animals that lived with us. When there is little deposition, there are few fossils.' A key feature helping archaeologists to understand humanity's evolution are structural basins, or 'bowls' on Earth's surface that naturally collect layers of sediment better than the surrounding landscape does — like the Turkana Basin stretching across southern Ethiopia and northern Kenya, Melillo said. Previous research has found evidence to suggest that Homo and Paranthropus coexisted there 1.5 million years ago. The new study focuses on the Afar Depression, a basin to the north of the Turkana. 'This contribution by Villmoare and colleagues demonstrates that in the Afar there was also some other species around with Homo — but it isn't Paranthropus,' Melillo said. 'Instead, they identify this 'non-Homo' genus as Australopithecus. They do a very convincing job of demonstrating why the new fossils are not Paranthropus.' The study adds to growing evidence that Australopithecus was not roaming the Afar Depression alone, she said. A mysterious coexistence When Australopithecus and Homo were alive, the Afar Region, now mostly a semidesert, had much more seasonal variation in rainfall than it does today, Reed said. Millions of years ago, the environment there was still dominated by a dry season, but it was interrupted by a brief wet season. Rivers that carried water across the landscape existed for only part of the year. Few trees grew near the river, and the environment nearby was largely wetlands and grasslands. 'We have a fossil giraffe species that was eating grass, which probably indicates they were stressed as they eat trees and bushes almost every place else,' Reed said. 'Were the hominins eating the same thing? We are trying to find out by examining isotopes in their teeth and microscopic scratches on their teeth.' Understanding whether or not Homo and Australopithecus had the same food sources could paint a portrait of how our ancient ancestors shared or competed for resources, Reed said. The team also wants to try to identify which hominin made the stone tools found at the site. At the moment it's impossible to tell exactly how the two hominins coexisted, but Reed said she is hoping that future findings will provide more answers. 'Whenever you have an exciting discovery, if you're a paleontologist, you always know that you need more information,' Reed said. 'You need more fossils. More fossils will help us tell the story of what happened to our ancestors a long time ago — but because we're the survivors we know that it happened to us.'

New Genetic Test Predicts Children With Future Risk of High BMI
A new test helps predict which kids face the largest genetic risk of a high body mass index (BMI) later in life. That could help parents establish healthy habits early on. The new test, put together by a large team of international researchers, is what's known as a polygenic score or PGS. These scores are used to group genetic variations to predict a certain characteristic, which in this case is BMI. Related: "What makes the score so powerful is its ability to predict, before the age of five, whether a child is likely to develop obesity in adulthood, well before other risk factors start to shape their weight later in childhood," says genetic epidemiologist Roelof Smit, from the University of Copenhagen in Denmark. "Intervening at this point can have a huge impact." It's important to note that the test isn't quite as straightforward as it might sound. For one, genetics only accounts for a relatively small proportion of risk for high BMI. And secondly, a growing body of research is suggesting we move away from BMI as a measure of obesity and health in general. Still, the researchers claim the new PGS test is up to twice as accurate as others of its type. It was built from a database of genetic information collected from more than 5.1 million people. After compiling the test, the researchers then tried it out on several separate health databases, covering hundreds of thousands of individuals. In these datasets, both genetic data and BMI over time had been recorded. The researchers added the PGS to other predictors of BMI, and found that higher PGS scores were associated with greater adult weight gain. The accuracy of the PGS at predicting BMI variation depended on age and ancestry. PGS scores at the age of 5 explained 35 percent of the BMI variation at age 18. For middle-aged Europeans, it accounted for 17.6 percent of the variation. In other groups it was much lower: just 2.2 percent for rural Ugandans, for example. This is probably down to underrepresentation in the training data, and the greater genetic diversity in African populations, the researchers say. Another interesting finding from the study: those with stronger genetic predisposition towards having a higher BMI actually lost more weight during the first year of weight loss programs, although they were also more likely to regain weight later. "Our findings emphasize that individuals with a high genetic predisposition to obesity may respond more to lifestyle changes and, thus, contrast with the determinist view that genetic predisposition is unmodifiable," write the researchers in their published paper. The thinking is that if BMI can be predicted more accurately at an early age, that gives those kids and their parents a bigger window of time to instill healthier habits regarding diet or activity levels, which have the potential to influence BMI. "This new polygenic score is a dramatic improvement in predictive power and a leap forward in the genetic prediction of obesity risk, which brings us much closer to clinically useful genetic testing," says geneticist Ruth Loos, from the University of Copenhagen. The research has been published in Nature Medicine.
