Ancient plague was already deadly 5,500 years ago, study reveals

21 June 2026 at 12:12

Plague is often linked to medieval Europe, crowded cities, and rats carrying infected fleas. However, a new study published in the journal Nature shows that the disease was already killing people thousands of years earlier. Researchers have discovered that plague caused deadly outbreaks among hunter-gatherers in Siberia about 5,500 years ago, long before cities and […]

Experience the Magic of Stonehenge from Your Sofa This Solstice

21 June 2026 at 00:17

A groundbreaking digital venture has been launched, promising to revolutionize the way the world experiences prehistoric heritage. The Virtual World of Stonehenge, an innovative online platform, allows users globally to immerse themselves in the fascinating history and archaeology surrounding the iconic Stonehenge site. Developed through a collaboration between the University of Reading and the British Museum, this free-to-access digital experience offers unparalleled access to one of the most significant prehistoric collections ever assembled, transcending the limitations of physical museum visits and bringing the past vividly into the present.

Launching precisely on June 21st to coincide with the summer solstice—a date of profound importance to Stonehenge and its cultural legacy—the Virtual World of Stonehenge goes far beyond a traditional replication of the physical exhibition. While the original 2022 British Museum showcase brought together over 400 objects from 36 European institutions and attracted nearly 200,000 visitors, this online experience transcends geographical and physical boundaries. It invites users to explore prehistoric Britain interactively, offering a dynamic temporal dimension where Stonehenge is seen morphing through various epochs, shedding light on its multifaceted evolution and significance.

The project’s technological core lies in its sophisticated use of 3D laser scanning, digital animation, and immersive soundscapes, created by a multidisciplinary team of archaeologists, digital heritage experts, and computer scientists. During the exhibition’s final weeks in 2022, a highly detailed laser scan of the British Museum gallery was captured, serving as the digital blueprint for the virtual environment. These precise measurements ensured every artifact and spatial detail was faithfully rendered, enabling users to navigate authentically within the gallery or step inside reconstructed prehistoric landscapes like the Neolithic flint mines at Grimes Graves.

One of the most compelling features of the Virtual World of Stonehenge is its ability to shed light on nuanced archaeological narratives often missed by conventional displays. The platform highlights lesser-known prehistoric relics such as a 6,000-year-old elm leaf, a delicately woven cow-hair bracelet, and remnants of ancient feasts, employing animation and interactive storytelling to contextualize these objects within the daily lives and rituals of Stonehenge’s ancient communities. This approach not only enhances engagement but fosters a deeper appreciation of the complex social and cultural fabric that shaped prehistoric Britain.

Professor Duncan Garrow of the University of Reading emphasizes the transformative educational potential of the project. By uniting an extraordinary assemblage of artifacts rarely seen together, the Virtual World of Stonehenge offers an immersive learning environment where users can interrogate the intersection between archaeological evidence and lived experience. This digital format allows for multi-sensory exploration—users can observe how the monument aligned with celestial phenomena, hear recreated ambient sounds, and engage with layered historical interpretations, bringing prehistoric Britain to life in a manner previously unachievable in museum contexts.

At the same time, Dr. Neil Wilkin, curator at the British Museum, highlights the project’s forward-thinking implications for museum engagement in the twenty-first century. The initiative serves as a prototype for virtual exhibitions that can extend the reach of cultural institutions globally, fostering inclusivity by making world-class collections accessible regardless of physical or economic barriers. Moreover, the integration of cutting-edge technologies heralds a new era of digital heritage preservation and public archaeology, where virtual experiences can complement and enhance traditional curatorial practices.

Technically, the Virtual World of Stonehenge exemplifies an advanced convergence of archaeological survey methods and digital tools. The laser scanning process produced millions of data points, constructing an ultra-high-resolution 3D model of the gallery space and its constituent objects. This geospatial accuracy underpins the digital environment’s interactivity, allowing users to manipulate views, zoom in on minute details, and gain spatial insights that static images or text-based descriptions cannot offer. Additionally, the underpinning narrative content draws on extensive archaeological research funded by UK Research and Innovation and the Arts and Humanities Research Council, ensuring both scholarly rigor and public accessibility.

The virtual platform’s sound design is equally innovative, using ambient recordings and reconstructed acoustic profiles to immerse visitors in the sensory atmosphere of the prehistoric world. For example, users can experience the atmospheric sounds of the summer solstice sunrise illuminating Stonehenge, or hear the ambient clatter from the flint mines at Grimes Graves, thereby deepening emotional connection and contextual understanding. This multisensory integration reinforces the project’s ambition to be more than a virtual museum tour, positioning it as a holistic archaeological experience harmonizing visual, auditory, and intellectual engagement.

Besides its public and educational impact, the Virtual World of Stonehenge also advances archaeological methodology by providing a scalable model for digital conservation. The high-fidelity digital capture serves as a preservation tool that mitigates risks associated with physical artifact degradation, travel restrictions, or exhibition deinstallations. Institutions across the globe can look to this project as a template for safeguarding and sharing their collections, leveraging virtual reality and interactive media to future-proof cultural heritage—an urgent priority amid climate change, urban development, and other preservation challenges.

Moreover, the project opens exciting avenues for interdisciplinary research by integrating digital humanities, archaeology, and computer science domains. The collaboration between British Museum curators, university archaeologists, and heritage technology firms like ArtasMedia demonstrates an effective alliance between academia and industry. Such partnerships facilitate the application of emerging technologies to solve complex questions about human history, potentially inspiring new methodologies in archaeological visualization, data interpretation, and public outreach that can be adapted to other cultural contexts and time periods.

Crucially, the Virtual World of Stonehenge also taps into the emotive and symbolic power of the site itself. Stonehenge’s exact astronomical alignments during the solstice are reconstructed with scientific precision, allowing users to witness how the monument interacts with the rising sun on this pivotal day. This temporal accuracy does not merely serve aesthetic purposes but conveys the profound cosmological knowledge possessed by its Neolithic and Bronze Age builders, adding layers of meaning to the experience and underscoring the monument’s enduring significance across millennia.

The accessibility of this virtual exhibition across multiple devices—including desktop computers, tablets, and smartphones—ensures that a diverse global audience can engage with Stonehenge’s prehistoric narratives regardless of location or technological proficiency. Such democratization of cultural heritage promotes wider public interest in archaeology while also inspiring future generations of researchers, educators, and enthusiasts. The response to the initial trial phases and media previews has been overwhelmingly positive, pointing to an appetite for more immersive, interactive digital humanities projects that redefine museum experiences.

In conclusion, the Virtual World of Stonehenge stands at the vanguard of a digital revolution in cultural heritage. By bridging meticulous archaeological scholarship with transformative technological innovation, it offers an unprecedented opportunity to explore prehistoric Britain in an expansive, nuanced, and engaging manner. This free, globally accessible experience not only honors Stonehenge’s profound historical legacy but also envisions a future where heritage and technology converge, bringing the deep past into the digital age and captivating audiences worldwide.

Ancient Mongolian cemetery reveals power and status mattered more than blood ties

20 June 2026 at 18:00
On the edge of the Mongolian steppe, overlooking where two rivers meet, lies an ancient cemetery. Buried within are two families, traced through ancient DNA across six generations, surrounded by dozens of "strangers." The obvious assumption is that this was a family cemetery. But a recent study used machine learning and a technique borrowed from evolutionary biology to reveal that what really mattered was wealth, status and political power, not blood.

Unearthed bathhouse reveals a thriving Roman Nijmegen: 'The Romans did not regard this city as a backwater'

19 June 2026 at 14:40
Excavations in Nijmegen-West have uncovered large sections of a Roman bathhouse. It is the largest bathhouse complex from the Roman period in the Netherlands. Radboud researcher Stephan Mols can often be found at the excavation site. "The new finds show that the Romans did not regard this city as a backwater. The buildings were even larger and more imposing than we had previously thought."

Denisovan DNA influences the immune systems of modern Oceanians — but researchers aren't sure why

18 June 2026 at 21:13

Some people from Oceania harbor thousands of genetic variants inherited from the Denisovans ‪—‬ a mysterious group of extinct humans ‪—‬ that are still active in their immune systems today, a new study finds.

The findings, published June 11 in the journal Science, come from the largest-ever map of Denisovan-inherited DNA ever created. The discovery shows that Denisovan DNA "is not just a remnant of ancient liaisons; it continues to influence our biology today," study co-author Serena Tucci, an assistant professor of anthropology and head of the Human Evolutionary Genomics Laboratory at Yale University, said in a statement.

Experiments revealed 3,127 variants inherited from Denisovans that still function in the immune systems of modern-day people; some of these variants switch genes that turn the immune response on or off, according to the new research.

However, because many of the immune system genes identified also affect other bodily functions, it is unclear exactly how these genes benefited survival, study first author Patrick Reilly, an evolutionary genomics researcher at Yale, told Live Science.

Denisovan DNA is active in humans today

Previous research has already found that some modern-day people in Oceania ‪—‬ a region that includes New Guinea, the Solomon Islands and Fiji ‪—‬ have some Denisovan DNA. For example, people from Papua New Guinea are known to carry up to 5% Denisovan DNA in their genomes thanks to prehistoric trysts with the enigmatic group of humans who lived in Asia and disappeared around 30,000 years ago. This is among the highest proportion in the world, with modern-day East Asians typically carrying only around 0.1% Denisovan DNA.

Previous research has also shown that modern-day Tibetans carry a Denisovan version of the EPAS1 gene that supports their adaptation to living at high altitudes. People living in the highlands and lowlands of Papua New Guinea have different Denisovan gene variants depending on their local environments.

Yet Oceanians are vastly underrepresented in genomic databases. Sequencing the genomes of Oceanians can give a glimpse into the lives of the Denisovans and is essential for closing gaps in health disparities in Pacific Islanders as a whole, Reilly said.

To fill this gap, Tucci and her team sequenced the genomes of 177 Oceanians from 12 populations and compared them to 1,284 previously published genomes from populations worldwide. Then, they compared these segments to the known Denisovan genome and three Neanderthal genomes.

Combined, the team built a catalog containing three times more Denisovan genetic sequences inherited from Denisovans than were previously identified, over 70% of which were unique to Oceanians.

Natural selection increased the frequency of some of these variants in people from Near Oceania, which includes New Guinea, the Bismarck Archipelago and the Solomon Islands in the Pacific Ocean, including genes linked to bone development, metabolism and fertility.

The team also ran experiments to assess whether any of the Densiovan DNA was changing how genes behaved in these populations, Reilly said.

This revealed that Denisovan genetic variants can switch various immune system genes on or off, although the exact immune functions that were targeted varied among the Oceanic populations studied.

Early migrants to Oceania at least 42,000 years ago benefited from Denisovan genes when they entered their new environment and encountered new disease-causing pathogens, Reilly said.

"This is consistent with multiple independent instances of local adaptation in response to novel immune environments and pathogens during human dispersal into the Pacific," the authors wrote in the study.

Although the researchers don't know exactly why natural selection acted on these genes, the findings highlight the major role pathogens played in shaping the way humans and our extinct relatives evolved, Reilly said.

The research is an "outstanding effort to try to understand the biological implications" of the enduring Denisovan genetic variants, Mathilde André, an evolutionary geneticist at the Pasteur Institute in France who was not involved in the study, told Live Science in an email.

The tripling of known Denisovan-inherited genetic sequences, most of which are unique to Oceanians, highlights the need to sequence the genomes from previously unrepresented populations to capture the diversity of Denisovan DNA, André said.

Did Neanderthals use rhinoceros teeth as tools?

18 June 2026 at 19:20
The RINO project was born from the discovery of unusual marks on rhinoceros teeth recovered from the prehistoric Payre site in France's Rhône Valley. The study of fossil rhinoceros teeth from this Middle Paleolithic site, dating to around 250,000–130,000 years ago, provides unprecedented evidence that Neanderthals used them as tools.

Hunter-gatherers in Siberia died of a plague outbreak 5,500 years ago

18 June 2026 at 16:04

Plague swept through groups of hunter-gatherers in southeastern Siberia 5,500 years ago, leaving dozens dead in its wake—with DNA from Yersinia pestis bacteria still trapped inside their teeth.

University of Oxford ancient DNA researcher Ruairidh Macleod and his colleagues recently sequenced the telltale bacterial DNA in teeth from plague victims at four ancient cemeteries in the area around Russia’s Lake Baikal. The tragedy that befell these communities is now the earliest known plague outbreak, courtesy of the oldest strain of Y. pestis ever sequenced.

Unearthing a new backstory for the plague

Until recently, scientists who study the evolution of diseases have held two fairly solid ideas about the origins of plague, the disease caused by Yersinia pestis bacteria. It's a scourge so awful that it has gone down in history as not just a plague but the plague. The first idea is that the earliest strains didn't have the right genetic traits to be really lethal. And the second is that the plague first began menacing humans when the first farmers settled in densely packed towns alongside rats and domestic animals.

Archaeologists Discover Stonehenge ‘Prototype’ Constructed 500 Years Before Britain’s Most Famous Megalithic Site

18 June 2026 at 13:04


A research team from Wessex Archaeology, led by Phil Harding, has announced the discovery of a Stonehenge ‘prototype’ structure, similarly aligned with the solstices, that may have served as an early proof of concept for the more famous structure built 500 years later.

The team behind the historic discovery said that the ancient date represents the earliest known alignment with the solstices and offers potential insights into the religion, belief systems, scientific knowledge, and worship practices of the ancient monument builders.

Location of Stonehenge Prototype Excavated a Decade Earlier

According to a statement announcing the discovery of the Stonehenge prototype, the structure is located 5 kilometers from the better-known stone circle. They also note that Stonehenge’s earliest earthworks were beginning construction around this same time.

Previous expeditions to the site conducted between 2015 and 2017 unearthed 48 pits, which those researchers dated to more than 2,000 years before the new find, or roughly 2,950 BCE. Still, the team notes that earlier efforts uncovered samples of pottery, animal bones, flints, and charcoal, suggesting that “large numbers of people gathered here over a relatively short period of time” to celebrate the longest day of the year.

Notably, one of the pits unearthed in the earlier excavations included what the team described as a possible “viewing station.” The pit also contained a disc-shaped knife, which the team notes “was deliberately placed here possibly as a symbolic reference to the sun disc.”

Still, the original effort left several tantalizing clues, leading to the new excavations.

Wooden Poles Align With the Solstices to Within One Degree

Instead of exploring the previously discovered pits, the team focused on the rest of the site. This effort led to the discovery of a pair of wooden pole pits placed 120 meters apart. According to the Wessex Archaeology team’s statement, the site’s ancient builders positioned the poles in the pits “to form a line pointing directly at the rising sun during the summer solstice and at the setting sun during (the) winter solstice.”

Although little of the structure remains, except for the pits where the poles once stood, the team was able to extract enough organic material to date the likely construction period of the structure. A radiocarbon analysis showed that the summer solstice poles were likely set around 5,000 years ago, more than 2,000 years earlier than the other pits at the same site. Perhaps even more surprisingly, the date placed the construction of the wooden poles roughly 500 years before ancient engineers built the world-famous site of Stonehenge.

To confirm the astronomical alignment, the team reached out to archaeologist Fabio Silva. According to the team’s statement, Dr. Silva, a Skyscape Archaeologist at Stone x Sky and the Skyscape Academy, used ancient reconstructions of the sky and the landscape to show that the structure would have aligned with the summer solstice “within an accuracy of one degree.”

When discussing the site’s potential uses, the researchers note that it would have served as a temporary gathering place for ancient celebrations of the summer and winter solstices until a more permanent structure could take its place. They even suggest that a similar structure may have been used in Stonehenge’s earliest phases, while conceding that traces of any similar alignment would have been erased by later construction.

Harding, who led the excavations, said the discovery of a possible Stonehenge prototype “is probably one of the greatest finds of my career,” while adding that the early date is what makes it so exceptional.

“Up till now, our knowledge of this ancient feat of astronomy was based on Stonehenge and other monuments of a similar period, but what we’ve discovered at Bulford is 500 years earlier than the famous stones we know so well,” Harding explained. “It makes me incredibly proud to be an archaeologist.”

“Part of a Much Longer Conversation Between People, the Land, and the Sky”

Although the ancient structure revealed a scientific knowledge predating Stonehenge by several centuries, Dr Matt Leivers, Senior Research Manager at Wessex Archaeology, said the discovery of a clearly religious site is “fundamental” because it is the earliest example of people building structures at this historically significant location “that aim directly at the solstice.”

“When we talk about the solstice, we’re talking about religion,” Dr. Leivers said. “About how prehistoric peoples understood the cosmos, the world, and their place in it.”

“It’s likely their way of saying to their deities, please keep us in mind, keep us warm and safe,” he added.

Dr Silva noted the historical significance in relation to Stonehenge, since the site shows that ancient communities “were already engaging with both the summer and winter solstices” in the same general area hundreds of years before the larger, more famous stones were put in place. The researcher also said the findings allow historians to see Stonehenge as more than a singular creation, but “as part of a much longer conversation between people, the land, and the sky.”

“Rather than marking the beginning of a story, Stonehenge now more clearly appears to have emerged from traditions and practices with much deeper roots in this landscape,” Dr. Silva concluded.

5,000-year-old 'prototype' Stonehenge aligning with solstices discovered near the famous Stone Age monument

18 June 2026 at 00:01

Evidence of two ancient wooden posts aligned with the summer and winter solstices has been discovered near Stonehenge in southwest England. The posts have rotted away, and only traces of the postholes survive. But archaeologists say the structure predated Stonehenge, and they think it was a temporary religious monument until a permanent one was built. They even suggest it may have been a Stonehenge prototype.

Analysis suggests that ancient people used the posts to mark the summer and winter solstices, Phil Harding, an archaeologist at Wessex Archaeology who's leading the project, noted at a news conference on Wednesday (June 17).

"These people were capable of establishing the points on the horizon where the sun rises in the midsummer and sets in midwinter," he said. "This was a pioneering achievement." (The 2026 summer solstice will be celebrated at Stonehenge on June 21.)

Harding's team at Wessex Archaeology, a private firm that often works for the government and local authorities, publicly announced the finds June 18 in the U.K., and a report on their research will be peer-reviewed and published. The ancient monument consisted of the two large, wooden posts, about 400 feet (120 meters) apart, on land near the village of Bulford, a few miles east of Stonehenge.

The land is now controlled by the U.K. Ministry of Defence, but archaeologists have been allowed to excavate there since 2015. They previously found traces of two "henges" ‪—‬ rings of ditches and banks made from earth ‪—‬ and dozens of Neolithic pits from about 5,000 years ago, centuries before Stonehenge was completed. The pits were filled with animal bones, pottery, flints and charcoal, and the researchers think they date to the time that the first phase of Stonehenge was being built.

Solstice alignment

The posts were aligned to point along an axis that marked the direction of sunrise on the summer solstice, or "midsummer's day," and the setting of the sun exactly six months later, at the winter solstice, or "midwinter's day," according to a statement from Wessex Archaeology. The same astronomical alignments are seen at Stonehenge.

The animal bones and other signs of feasting in the pits at Bulford are evidence of large numbers of people gathering for religious festivals. (Signs of ancient feasting have also been found at Stonehenge.)

"When we talk about the solstice, we're talking about religion," Matt Leivers, an archaeologist at Wessex Archaeology and one of the researchers, said in the statement. "What we see at Bulford, and later at Stonehenge, is a way of celebrating and marking the passage of time, but it's also about making sure the world keeps working as it should."

The site predates the largest circles of stones at Stonehenge, which have the same alignments. "What we've discovered at Bulford is 500 years earlier than the famous stones we know so well," Harding said. The researchers even suggest that the Bulford monument may have been a sort of prototype for Stonehenge itself.

Ancient stones

Stonehenge is the world's most famous Neolithic monument, but its original purpose was long a mystery. Archaeological investigations have established that the first earthwork henge was started there about 5,000 years ago, and the famous central stones were added about 500 years later.

Recent discoveries at Stonehenge include evidence of ancient cremations, and many archaeologists now think the monument was originally a burial site. If that's the case, the alignment with sunset on the winter solstice might have represented "new life," as the days then became longer and warmer after the depths of winter. However, no human remains have been found at the Bulford site.

Susan Greaney, an archaeologist at the University of Exeter who was not involved in the research, said the new finds show the importance of the region to prehistoric people. "It is intriguing to think that simple posts were erected here to align with the solstices around 500 years before Stonehenge was built," she told Live Science.

The Bulford monument may have been a temporary "model" for Stonehenge itself, Amanda Chadburn, an independent archaeologist who wasn't involved in the research, told Live Science "If you were designing a very complicated piece of engineering like Stonehenge," she said, "you would have had to understand how to make it before starting."

Ancient curse tablet bears rare Greek inscription with binding spell intended to harm enemies

17 June 2026 at 22:20
Heidelberg University researchers have deciphered the inscription on an ancient curse tablet, which was once used to invoke deities and demons in order to harm an enemy. The "magical" artifact from the Roman province of Lower Germania was discovered during excavations carried out in the Dutch municipality of Heerlen. The lead tablet, which dates to the 2nd century A.D., is distinctive in that it contains not a Latin but an ancient Greek text in the Egyptian style, as Dr. Rodney Ast, academic director at the Institute for Papyrology, explains.

'It's a huge deal': Archaeologists discover second cannonball from the Battle of the Alamo, and it was likely fired by Texans

Archaeologists have discovered an iron cannonball fired by Texans at the Battle of the Alamo in 1836. This is the second intact cannonball they have discovered from the famous conflict. The first one, a bronze cannonball, was found earlier this year and was likely fired by the Mexican army.

"It's a huge deal," Tiffany Lindley, director of archaeology at the Alamo, said in a video statement from Alamo Trust. "We all thought, 'There's no way we can top it,'" she said, referring to the bronze cannonball discovered March 5, just a day before the 190th anniversary of the conflict that killed Davy Crockett, "and then we found another one."

Both cannonballs were recovered from the northeast corner of the church at the Alamo, which was originally built in 1718 as a Spanish mission and fortress in what is now San Antonio. But the Alamo is better known as the location of an 1836 battle during the Texas Revolution, in which Anglo-American settlers and Hispanic Texans known as Tejanos seceded from the Republic of Mexico.

In a 13-day siege culminating in a deadly assault on March 6, 1836, Mexican troops, commanded by Gen. Antonio López de Santa Anna, surrounded the Alamo and killed the 180 Texan rebels defending the structure, including Davy Crockett. The cry "Remember the Alamo!" was used in later skirmishes in the Texas Revolution as soldiers fought Mexican troops for independence.

The newly excavated iron cannonball was found June 2, according to a statement from Alamo Trust.

Of the two cannonballs, "the newest one is slightly larger" and was likely fired from a cannon that shot 6-pound [2.7 kilogram] cannonballs, Kolby Lanham, a senior researcher and historian at the Alamo, said in the statement. "The likelihood is that the bronze one belonged to the Mexican Army and the iron one belonged to the Texans."

Over the years, archaeologists have found numerous pieces of ammunition and shrapnel at the Alamo, Lindley said, but these cannonballs are the first examples of solid shots — spherical projectiles fired from a gun or cannon — they have ever found.

"It's just a huge kind of once-in-a-lifetime deal," Lanham said. "But obviously, it's happened twice."

The Mexican and Texan cannonballs were found near each other, so they are likely the historic remains of the two sides shooting at each other in the fateful siege nearly two centuries ago.

"Whenever they were dropped the very first time — possibly in 1836, probably — they haven't been touched since, and that's what makes them extra special," Lindley said. "I don't think you can undersell it."

The Alamo remains an active archaeological site, where experts have discovered artifacts that span its centuries of history, from Indigenous stone tools that predate the Spanish mission through the late 19th century, when the structure was converted into a general store and warehouse.

Oldest known plague victims found in a 5,500-year-old burial ground in Siberia — and many of them were children

17 June 2026 at 18:43

Hunter-gatherers in Siberia fell victim to lethal plague outbreaks around 5,500 years ago, marking the oldest known evidence of plague to date, a new study finds.

A research team investigating the Stone Age remains identified ancient DNA ion over a dozen individuals that came from previously unknown strains of Yersinia pestis, a bacterium that causes pneumonic, bubonic and septicemic plague.

The disease that infected these hunter-gatherers, most likely pneumonic plague, probably spilled over from wild marmots, and ravaged through family groups living around Lake Baikal, according to the study, published Wednesday (June 17) in the journal Nature.

Ancient DNA from the two newfound plague strains revealed a unique gene that codes for proteins that trigger massive immune responses, perhaps explaining why children were the most likely to die from the disease, the authors wrote in the study.

The discovery of two deadly plague outbreaks in prehistoric hunter-gatherers challenges the long-standing assumption that epidemics first occurred after the rise of agriculture, study first author Ruairidh Macleod, a researcher of ancient genomics at the University of Oxford, told Live Science.

"We got the really striking result that we found lots and lots of plague here far earlier than we expected," Macleod said. This is "the closest we'll probably ever get to a direct smoking gun demonstrating the virulence [the ability of germs to cause disease] of these early plagues."

Plague has played an extremely important part in human history and continues to infect people today. The strain of Y. pestis that affects people today still causes epidemics, predominantly in Africa, although seven human cases, on average, are reported in the U.S. each year. Nowadays, Y. pestis cases that are caught early can be treated with antibiotics.

Understanding how the disease has evolved over time is essential for gaining insight into how Y. pestis may change in the future, study co-author Eske Willerslev, an evolutionary geneticist at the University of Copenhagen, said at a news conference Tuesday (June 16), ahead of the study's publication.

Prehistoric plague outbreaks

Research suggests that plague outbreaks devastated communities long before the Black Death, the catastrophic epidemic that swept through 14th-century Europe and killed around 25 million people, or between 25% and 33% of Western Europe's population at the time.

For example, repeated plague outbreaks have been identified from between 5,300 and 4,900 years ago in farmers from what is now Scandinavia. However, whether these early plague strains were deadly or simply caused mild sickness has been hotly debated because the bacterium lacked some known disease-causing genes.

Now, a close inspection of the ancient DNA of hunter-gatherers buried in four cemeteries along the banks of the Angara River, which flows out of Lake Baikal, has provided "the best kind of evidence that we could probably hope for" that prehistoric plague strains were lethal and resulted in mass death, Macleod said.

During previous excavations of these cemeteries, researchers noticed that an unusually high number of children had been buried over a short period. There were no signs of violence or other injuries, Macleod said at the news conference, leaving the archaeologists stumped as to why so many children died.

Macleod and his team stepped in to see if ancient DNA could shed light on this mystery.

The researchers extracted ancient DNA from the teeth of 46 individuals at the four cemeteries. They checked whether any were related while also scanning for ancient DNA from known germs.

To their surprise, they identified large amounts of Y. pestis in 18 individuals. These cases spanned two distinct disease outbreaks: one lasting from around 5,596 to 5,341 years ago, and another most likely spanning 5,126 to 4,926 years ago.

Some graves contained the remains of multiple infected individuals who were buried at the same time, suggesting they died during the same outbreak. One grave belonged to three closely related young girls, while another held a nephew and aunt.

"There must have been survivors who knew these people when they were alive and what their identities were and what their biological relationships were to bury the dead and bury them in shared graves," Macleod said.

It is currently not possible to identify plague-specific antibodies that would identify which individuals survived the outbreaks, he added.

The findings help to support the idea that prehistoric populations were impacted by plague, Aida Andrades Valtueña, a researcher who specializes in ancient pathogens at the Max Planck Institute for Evolutionary Anthropology in Germany but was not involved in the study, told Live Science in an email.

However, more complete sequencing of the plague DNA is needed to confirm that the various cases were from the same outbreak, rather than from separate infections, she noted.
