The findings from the site, known as Soii Havzak, provide crucial evidence that Central Asia played a vital role in early human migration and development.
Elite Grave of Pre-Mongol Period Uncovered in Mongolia
A team of archaeologists led by Professors Gideon Shelach-Lavi from the Hebrew University of Jerusalem, Amartuvshin Chunaga from the National University of Mongolia and William Honeychurch from Yale University, has unearthed an elite grave dating back to the pre-Mongol period in Dornod Province, Mongolia. This finding, part of the Mongol-Israeli-American Archaeological Project, sheds new light on a poorly understood era on the Mongolian plateau, spanning the collapse of the Kitan Empire around 1125 CE to the rise of the Mongol Empire under Chinggis Khan in 1206 CE.
Archaeological Context and Significance
The Mongol-Israeli-American Archaeological Project has been conducting surveys and excavations along Kitan frontier 'long-walls' in northeastern Mongolia since 2018. The discovery of the Khar Nuur burial is one of the most significant findings of the project, offering valuable evidence of the cultural and political shifts that occurred in the lead-up to the rise of the Mongol Empire.
Several hypotheses have been proposed to explain the choice of burial location:
1. The Khar Nuur steppe nomads may have perceived the abandoned Kitan fortress as part of their own history and indigenous territory, using it to affirm local identity and social memory.
2. The fortress may have held symbolic prestige, making it a fitting site for the burial of a leading community member.
3. The burial could have been a deliberate display of power and territorial possession amid the political competition of the time.
These theories, while not mutually exclusive, offer a combined explanation for the social and political processes taking place on the eastern steppe during the post-Kitan period. As imperial authority waned and steppe groups vied for control, the Khar Nuur burial stands as a poignant symbol of identity, memory, and power in a time of transition.
Historical Implications
The discovery adds a vital piece to the puzzle of Mongolian history, providing a deeper understanding of the events and communities that shaped the region before the rise of the Mongol Empire. It offers valuable insights into how local communities maintained their networks and organization during a period of significant change and political competition.
"The Khar Nuur burial represents a unique window into the complex social and political landscape of 12th century Mongolia," added Prof. Shelach-Lavi. "It demonstrates how local elites may have used symbolic connections to past empires to legitimize their own power and status, even as they navigated a rapidly changing political environment."
This remarkable find not only enriches our understanding of pre-Mongol Empire Mongolia but also highlights the importance of continued archaeological research in uncovering the nuanced history of the region. As further analysis of the burial and its contents continues, researchers anticipate gaining even more insights into this pivotal period in Mongolian and world history.

Healthy Bees, Healthy Planet: The Impact of Balanced Diets on Honeybee Colonies
A new study has revealed that a balanced diet is crucial for the health and task performance of honeybees. The research shows that an unbalanced diet significantly delays the onset of nursing, reduces nursing frequency, and alters care for larvae. These findings highlight the importance of maintaining a balanced diet for honeybees to ensure their efficiency and survival, especially in cultivated landscapes with limited nutritionally balanced pollen sources.
A new study from the Hebrew University of Jerusalem has revealed that a balanced diet is essential for the optimal health and task performance of honeybees, a key species for pollination and ecosystem stability. The study, led by Prof. Sharoni Shafir from the Robert H. Smith Faculty of Agriculture, Food and Environment, investigates how honeybees balance their nutritional intake to maintain homeostasis and enhance fitness. The findings indicate that an unbalanced diet with a high omega-6:3 ratio (5:1) significantly affects the bees' ability to nurse larvae, delaying the onset of nursing, reducing the frequency of nursing visits, and altering the attention given to larvae of different ages.
To test these effects, one-day-old adult worker bees were fed either a balanced diet or an unbalanced diet for seven days. The bees were then released into a common-garden hive, tagged with barcodes, and continuously filmed for six days. The analysis revealed that those on the unbalanced diet exhibited delayed nursing behavior and reduced efficiency in caring for larvae, particularly in differentiating between three-day-old and four-day-old larvae.
"Balanced nutrition is fundamental for honeybee colonies, impacting not just individual health but also the overall efficiency and survival of the hive," said Prof. Shafir. "Our study underscores the importance of maintaining a balanced omega-6:3 ratio in the diet of honey bees to ensure they can perform their crucial roles within the colony effectively."
The implications of this research are far-reaching, particularly in cultivated landscapes where the availability of nutritionally balanced pollen sources may be limited. The shift towards a greater omega-6:3 ratio in these areas could pose a significant threat to bee populations, affecting their health, cognitive abilities, and ability to sustain their colonies. "This study opens new avenues for further research linking fitness-related behaviors to nutritional balancing in honeybees," added Prof. Shafir. "It also highlights the need for conservation efforts to ensure diverse and nutritionally adequate pollen sources are available for these essential pollinators."
The research aligns with broader findings in other species, where nutritional imbalances are known to affect survival, reproductive success, and offspring health. It calls for increased awareness and measures to support the nutritional needs of honeybees, essential for maintaining their populations and the vital pollination services they provide.

Advanced Method for Rock Engraving Analysis: Computational Answers to Riddles on Stone
Researchers have developed a new method using ArchCUT3-D software to study rock engravings, integrating technological and visual analysis to reveal intricate details of ancient techniques. This new approach bridges the gap between production processes and visual outcomes, offering comprehensive insights into the cultural significance of engravings in Timna Park, southern Israel.
Historically, rock engravings have been examined primarily through their visual characteristics using comparative and interpretative methodologies. While recent works have focused on identifying production processes, these studies often neglected the visual outcomes. Dubinsky and Prof. Grosman’s research bridges this gap by using computational analysis to integrate both technological and visual aspects, offering a comprehensive understanding of ancient engraving practices.
"We employed ArchCUT3-D software to conduct a detailed analysis of 3-D data from various rock engravings. This method allowed us to extract micro-morphological evidence from engraved lines, decoding technical trends and variabilities in the execution of these ancient artworks. By examining a specific group of engraved figures, we established a link between the techniques used and the visual considerations guiding them," explains Lena Dubinsky.
Based on their findings, the researchers propose the term "Techné" to describe the choice of technique that goes beyond mere practicality, encompassing the intentional design and cultural concepts embedded in the engravings. This integrative approach challenges the traditional dichotomy between visual and technological research, presenting a unified framework for understanding ancient production acts.
The study highlights how social structures and individual actions influence production methods, suggesting that the decisions related to technique selection are reflective of broader sociocultural contexts. This perspective offers a richer narrative of ancient engravers' cognitive and material interactions, providing deeper insights into their cultural and technological environment.
The research underscores the potential of digital tools in archaeological studies. Their methodology not only advances the study of rock engravings but also sets a precedent for exploring other archaeological artifacts. By identifying "techno-visual codes" and the “fingerprints” of engraved complexes, this approach enhances our ability to understand the cultural and technological nuances of ancient societies.
"This study marks a significant step forward in archaeological research, combining advanced computational analysis with a nuanced understanding of ancient techniques and visual styles. It opens new avenues for exploring the interplay between technology and visuality in historical contexts, promising to deepen our knowledge of the past," says Prof. Grosman.

Archaeologists discover and replicate earliest musical instrument in the Middle East
Archaeologists are hearing for the first time how humans made music some 12,000 years ago, by recreating a flute that was likely used to hunt ducks and other small birds in northern Israel.
The French-Israeli team of archaeologists discovered fragments of seven different flutes, dating to around 10,000 BCE, which is the largest collection of prehistoric sound-producing instruments ever found in the Levant. The pieces were found at the Eynan/Ain Mallaha site, a small village some 35 km (20 miles) north of the Sea of Galilee. The site was inhabited from 12,000 BCE to 8,000 BCE, around the time when humans were undergoing a massive revolution from nomadic hunter-gatherers to more sedentary, semi-settled communities.
Dr. Laurent Davin, a post-doctoral fellow at Hebrew University, was examining some of the bones recovered from the site when he noticed tiny holes drilled at regular intervals along a few of the bones. At first, experts had dismissed the holes as regular wear and tear on the delicate bird bones. But Davin examined the bones more closely and noticed that the holes were at very even intervals, and clearly created by humans.
“One of the flutes was discovered complete, and so far as is known it is the only one in the world in this state of preservation,” Davin said in a press release that accompanied the article’s publication.
Dr. Hamoudi Khalaily, a senior researcher with the IAA, spent 10 years excavating at the Eynan site and was instrumental in creating a replica of the extant flute.
“There were a lot of doubts that this was even possible [to recreate], but the replica was created exactly [in the same way] as the original and it allowed us to hear what people would have heard 12,000 years ago,” Khalaily told The Times of Israel.
“When we first heard it, it gave us this feeling like, we are really doing something for history,” Khalaily said.
The recreated flute produces a screeching, breathy whistling sound that Khalaily and the team believe could be an imitation of predator birds, including falcons, which eat small waterfowl.
“The sound could have attracted predator birds, which creates chaos with the other birds, and then it’s very easy to catch them, even with your hands,” explained Khalaily.
Previously, nomadic hunter-gathers had focused on bigger game such as gazelles, rabbits, or foxes. But when humans began settling in the Hula Valley for the first time, they started taking advantage of new food sources, including fish and smaller waterfowl in the lake that used to stretch across the Hula Valley.
Today, the Hula Valley is still a major conduit for bird migration in the late fall when tens of thousands of birds pass through Israel on their way from Europe to Africa. The Hula Valley was once covered by water, with a 13 square kilometer (5 square mile) lake and 47 square kilometers (18 square miles) of seasonal swamps. Early Zionist pioneers drained the swamp in the early 20th century as a major infrastructure project to create more agricultural land and to combat malaria.
A trove of bird bones
At the Eynan site, archaeologists are excavating a small Natufian village, which was a Mesolithic culture in the Levant and Western Asia around 9000 BCE. It’s a unique time because the culture emerged when humans started living a semi-sedentary lifestyle predating the agricultural revolution, meaning they had to find regular food sources in the same area even before they knew how to cultivate them. Once humans became more settled, their culture underwent dramatic societal change including the appearance of burial practices, art, and durable structures.
The Eynan site was first excavated by a French mission in 1955 and later from 1996–2005 by a joint team from Israel and France directed by François Valla of the Centre Nationale de Recherche Scientifique (CNRS) and Khalaily of the Israel Antiquities Authority.
Excavations at the site are ongoing and it can take years to methodically sift through all of the earth removed from a site and search for fragments of tools, animal bones, or other detritus from daily life thousands of years ago. Over the past two decades, careful sifting has yielded 1,112 bird bones from the Eynan site.
The bone flute was researched and recreated by a team of French and Israeli experts, consisting of archaeologists and archaeozoologists, who study animal bones, ethnomusicologists, paleo-organologists (the research of ancient sound-making instruments), and technical experts that were able to find ways to recreate the exact placement of the finger holes.
The original flutes, also called aerophones because they are an instrument that produces sound due to vibrating air, were made from the hollow wing bones of the Eurasian teal and the Eurasian coot. The current replica was made from the wing bones of two female mallard ducks “because of the difficulty in obtaining carcasses of Eurasian coot (Fulica atra) used by the Natufians,” the article stated.
The tinier the bone, the more difficult it is to play. The researchers believe the bones were chosen specifically to mimic the calls of the Eurasian Sparrowhawk and the Common Kestrel, two birds of prey that were widespread in the Hula Valley.
The flute represents the oldest musical instrument found locally, but it is not the oldest aerophone that has been discovered. Most of the known Paleolithic sound-making instruments are found in Europe, and the oldest dates to around 40,000 years ago, which was found in southwestern Germany, made from bird bone and mammoth ivory.
Previous to this discovery, the only known “music” or sound production during the Paleolithic and Neolithic periods in the Levant was from a few studies suggesting that humans could have developed a belt of bone pendants that clacked and rattled, or possibly a bone whistle (flute with no fingerholes).
The flute represents an important discovery, but it’s not music to everyone’s ears.
“I heard it for the first time on Youtube, and it’s really a terrible tone, it’s high and pitchy and not nice at all to my ear,” said Prof. Rivka Rabinovich, the scientific director of archeozoological collections at the National Natural History Collections at the Hebrew University. Rabinovich, an expert in studying and interpreting the remains of ancient mammal bones has been studying the discoveries from the Eynan site for years.
Rabinovich added that there’s no way of knowing whether ancient humans had a similar cringe reaction when they heard it; whether it was used for hunting, communication, or making music.
But it opens a window into a fascinating point in human development, the complexity of society and their ability to make tools. The small finger holes in the flute were drilled with the talon of a larger bird, likely a falcon. Archaeologists believe that talons also had spiritual significance to early humans, Khalaily said.
“It’s very interesting because this is just at the starting point of people becoming more sedentary,” Rabinovich said. “It’s a very exciting period at which to understand the day-to-day life and also larger questions beyond day-to-day life, and why they did certain things.”
She credited the discovery to the large and varied French-Israeli team, which united researchers and archaeologists with areas of expertise in niche areas like reconstructing bone tools and interpreting scratches made in animal bones.
“The message from this is that you really need to save everything [excavated from a site] because you always see these things with new eyes and new tools,” she said. “It takes a long time to sift through things, and when you look at it anew, you can see it differently. That’s because there’s continually new research, there’s continually new technology, and new ways to investigate new information. And it all works together to create a more complete picture of what happened there.”
The Eynan site hosted continuous human presence for around 4,000 years, with people living in round houses made of stones with animal hides or branches for roofs. In 8,000 BCE, when the agricultural revolution was well underway, humans abandoned the site, moving around 500 meters closer to the Hula Lake, whose contours had changed with time.
One of the most important tests on the flute is yet to come: In late fall, when the annual bird migration through the Hula Valley takes place, Khalaily plans to take the replicated flute to the Eynan site and play it there, in the same spot where humans created it 12,000 years ago.
“I want to go and see if we can make these voices, in hopes of attracting a hawk or falcon,” he said. “I’m naturally an optimistic person, but I do really think it will work. If we were able to replicate this sound, I’m certain it will bring those birds to us.”
