    In ancient times, all roads led to Rome—or so the saying goes. Nowadays, new roads can lead to Roman ruins.
    During construction on an alternative route to D606, a regional road just under two miles outside of Auxerre, in central France, salvage archaeologists unearthed a sprawling Roman villa complete with a stately garden, a fountain and an elaborate system of underfloor heating known as a hypocaust, according to a statement from the French National Institute for Preventive Archaeological Research.
    While researchers have been aware of the ruins on the outskirts of the Gallo-Roman settlement of Autissiodorumsince the 19th century, previous excavations have been limited. The most recent dig, in 1966, found a 7,500-square-foot building with ten rooms and amenities that suggested its residents enjoyed great wealth and regional power.

    But until now, the true scale of the villa known as Sainte-Nitasse and its surrounding agricultural estates along the River Yonne was unclear. Archaeologists at INRAP have since discovered a 43,000-square-foot building thought to date to between the first and third centuries C.E. It suggests a previously unimagined level of grandeur.
    INRAP identifies the site as one of the “grand villas of Roman Gaul,” according to the statement. Grand villas are typified by their vast dimensions and sophisticated architectural style. They typically encompass both agricultural and residential portions, known in Latin as pars rustica and pars urbana, respectively. In the pars urbana, grand villas tend to feature stately construction materials like marble; extensive mosaics and frescoes; and amenities like private baths, fountains and gardens.
    So far, the excavations at Sainte-Nitasse have revealed all these features and more.
    The villa’s development is extensive. A 4,800-square-foot garden is enclosed by a fountain to the south and a water basin, or an ornamental pond, to the north. The hypocaust, an ancient system of central heating that circulated hot air beneath the floors of the house, signals a level of luxury atypical for rural estates in Roman Gaul.

    “We can imagine it as an ‘aristocratic’ villa, belonging to someone with riches, responsibilities—perhaps municipal, given the proximity to Auxerre—a landowner who had staff on site,” Alexandre Burgevin, the archaeologist in charge of the excavations with INRAP, tells France Info’s Lisa Guyenne.
    Near the banks of the Yonne, a thermal bath site contains several pools where the landowner and his family bathed. On the other side of the garden, workers toiled in the fields of a massive agricultural estate.
    Aside from its size and amenities, the villa’s level of preservation also astounded archaeologists. “For a rural site, it’s quite exceptional,” Burgevin tells L’Yonne Républicaine’s Titouan Stücker. “You can walk on floors from the time period, circulate between rooms like the Gallo-Romans did.”Over time, Autissiodorum grew to become a major city along the Via Agrippa, eventually earning the honor of serving as a provincial Roman capital by the fourth century C.E. As Gaul began slipping away from the Roman Empire around the same time, the prominence of the city fluctuated. INRAP archaeologists speculate that the site was repurposed during medieval times, around the 13th century.
    Burgevin offers several explanations for why the site remained so well preserved in subsequent centuries. The humid conditions along the banks of the river might have prevented excess decay. Since this portion of the River Yonne wasn’t canalized until the 19th century, engineers may have already been aware of the presence of ruins. Or, perhaps the rubble of the villa created “bumpy,” intractable soil that was “not easy to pass over with a tractor,” he tells France Info.
    While the site will briefly open to the public on June 15 for European Archaeology Days, an annual event held at sites across the continent, excavations will continue until September, at which time construction on the road will resume. Much work is to be done, including filling in large gaps of the site’s chronology between the Roman and medieval eras.
    “We have well-built walls but few objects,” says Burgevin, per L’Yonne Républicaine. “It will be necessary to continue digging to understand better.”

  • Tutankhamun's Iconic Gold Death Mask Is Getting a New Home Near the Pyramids of Giza

    Tutankhamun’s Iconic Gold Death Mask Is Getting a New Home Near the Pyramids of Giza
    Soon, the elaborately decorated artifact will be transferred to the brand new Grand Egyptian Museum, joining more than 5,000 other items from the boy king’s tomb

    For nearly a century, visitors have flocked to the Egyptian Museum on Cairo’s Tahrir Square to admire Tutankhamun’s funerary mask, the intricately decorated artifact designed to cover the mummified pharaoh’s face.
    Starting this summer, they’ll be able to see the mask in its new home, the billion Grand Egyptian Museum located in nearby Giza. Officials will soon transfer the mask to the massive new venue, where it will join more than 5,000 artifacts from the boy king’s tomb.
    “Only 26 objects from the Tutankhamun collection, including the golden mask and two coffins, remain herein Tahrir,” says Ali Abdel Halim, director of the Egyptian Museum, to the Agence France-Presse. “All are set to be moved soon.”
    Halim didn’t say when the death mask will be transferred, but the new Grand Egyptian Museum is scheduled to fully open to the public in early July after years of delays.
    Some portions of the Grand Egyptian Museum have been open since November 2023, with an additional 12 exhibit halls opening last October. All told, the museum complex spans more than 5 million square feet and houses more than 100,000 artifacts, which makes it the largest museum in the world focused on a single civilization.
    “We spent all this money to build the greatest museum in the world,” said Zahi Hawass, an Egyptologist who has twice served as Egypt's tourism and antiquities minister, to NBC News’ Keir Simmons, Charlene Gubash and Mithil Aggarwal in October. “You will see the objects for the first time in an incredible way.”

    The Untold Secrets of King Tut's Tomb
    Watch on

    Tutankhamun's mask has been housed at the Egyptian Museum in Cairo since 1934, 12 years after British archaeologist Howard Carter discovered the pharaoh’s tomb. However, the 123-year-old Beaux Arts venue is small and starting to show its age, so officials decided to relocate Tutankhamun's treasures to the enormous, high-tech Grand Egyptian Museum.
    At the new facility, the Tutankhamun artifacts will have their own dedicated, climate-controlled wing—one that’s large enough to display all of them together for the first time.
    Last month, officials carefully transferred 163 Tutankhamun treasures to the new museum, according to an announcement from the Egyptian Ministry of Tourism and Antiquities. That delivery included the pharaoh’s elaborately decorated ceremonial chair, various pieces of jewelry and the canopic chest that held the jars containing Tutankhamun’s organs, reports Artnet’s Sarah Cascone.
    The Egyptian Museum in Cairo, meanwhile, is not closing. Though it has lost Tutankhamun’s treasures and more than 20 mummies, it still has roughly 170,000 artifacts in its collection, per the AFP. Curators say they plan to replace the Tutankhamun artifacts with a new exhibition, though they haven’t shared many details.

  • How white-tailed deer came back from the brink of extinction

    Given their abundance in American backyards, gardens and highway corridors these days, it may be surprising to learn that white-tailed deer were nearly extinct about a century ago. While they currently number somewhere in the range of 30 million to 35 million, at the turn of the 20th century, there were as few as 300,000 whitetails across the entire continent: just 1% of the current population.

    This near-disappearance of deer was much discussed at the time. In 1854, Henry David Thoreau had written that no deer had been hunted near Concord, Massachusetts, for a generation. In his famous “Walden,” he reported:

    “One man still preserves the horns of the last deer that was killed in this vicinity, and another has told me the particulars of the hunt in which his uncle was engaged. The hunters were formerly a numerous and merry crew here.”

    But what happened to white-tailed deer? What drove them nearly to extinction, and then what brought them back from the brink?

    As a historical ecologist and environmental archaeologist, I have made it my job to answer these questions. Over the past decade, I’ve studied white-tailed deer bones from archaeological sites across the eastern United States, as well as historical records and ecological data, to help piece together the story of this species.

    Precolonial rise of deer populations

    White-tailed deer have been hunted from the earliest migrations of people into North America, more than 15,000 years ago. The species was far from the most important food resource at that time, though.

    Archaeological evidence suggests that white-tailed deer abundance only began to increase after the extinction of megafauna species like mammoths and mastodons opened up ecological niches for deer to fill. Deer bones become very common in archaeological sites from about 6,000 years ago onward, reflecting the economic and cultural importance of the species for Indigenous peoples.

    Despite being so frequently hunted, deer populations do not seem to have appreciably declined due to Indigenous hunting prior to AD 1600. Unlike elk or sturgeon, whose numbers were reduced by Indigenous hunters and fishers, white-tailed deer seem to have been resilient to human predation. While archaeologists have found some evidence for human-caused declines in certain parts of North America, other cases are more ambiguous, and deer certainly remained abundant throughout the past several millennia.

    Human use of fire could partly explain why white-tailed deer may have been resilient to hunting. Indigenous peoples across North America have long used controlled burning to promote ecosystem health, disturbing old vegetation to promote new growth. Deer love this sort of successional vegetation for food and cover, and thus thrive in previously burned habitats. Indigenous people may have therefore facilitated deer population growth, counteracting any harmful hunting pressure.

    More research is needed, but even though some hunting pressure is evident, the general picture from the precolonial era is that deer seem to have been doing just fine for thousands of years. Ecologists estimate that there were roughly 30 million white-tailed deer in North America on the eve of European colonization—about the same number as today.

    A 16th-century engraving depicts Indigenous Floridians hunting deer while disguised in deerskins.Colonial-era fall of deer numbers

    To better understand how deer populations changed in the colonial era, I recently analyzed deer bones from two archaeological sites in what is now Connecticut. My analysis suggests that hunting pressure on white-tailed deer increased almost as soon as European colonists arrived.

    At one site dated to the 11th to 14th centuriesI found that only about 7% to 10% of the deer killed were juveniles.

    Hunters generally don’t take juvenile deer if they’re frequently encountering adults, since adult deer tend to be larger, offering more meat and bigger hides. Additionally, hunting increases mortality on a deer herd but doesn’t directly affect fertility, so deer populations experiencing hunting pressure end up with juvenile-skewed age structures. For these reasons, this low percentage of juvenile deer prior to European colonization indicates minimal hunting pressure on local herds.

    However, at a nearby site occupied during the 17th century—just after European colonization—between 22% and 31% of the deer hunted were juveniles, suggesting a substantial increase in hunting pressure.

    This elevated hunting pressure likely resulted from the transformation of deer into a commodity for the first time. Venison, antlers and deerskins may have long been exchanged within Indigenous trade networks, but things changed drastically in the 17th century. European colonists integrated North America into a trans-Atlantic mercantile capitalist economic system with no precedent in Indigenous society. This applied new pressures to the continent’s natural resources.

    Deer—particularly their skins—were commodified and sold in markets in the colonies initially and, by the 18th century, in Europe as well. Deer were now being exploited by traders, merchants and manufacturers desiring profit, not simply hunters desiring meat or leather. It was the resulting hunting pressure that drove the species toward its extinction.

    20th-century rebound of white-tailed deer

    Thanks to the rise of the conservation movement in the late 19th and early 20th centuries, white-tailed deer survived their brush with extinction.

    Concerned citizens and outdoorsmen feared for the fate of deer and other wildlife, and pushed for new legislative protections.

    The Lacey Act of 1900, for example, banned interstate transport of poached game and—in combination with state-level protections—helped end commercial deer hunting by effectively de-commodifying the species. Aided by conservation-oriented hunting practices and reintroductions of deer from surviving populations to areas where they had been extirpated, white-tailed deer rebounded.

    The story of white-tailed deer underscores an important fact: Humans are not inherently damaging to the environment. Hunting from the 17th through 19th centuries threatened the existence of white-tailed deer, but precolonial Indigenous hunting and environmental management appear to have been relatively sustainable, and modern regulatory governance in the 20th century forestalled and reversed their looming extinction.

My analysis suggests that hunting pressure on white-tailed deer increased almost as soon as European colonists arrived. At one site dated to the 11th to 14th centuriesI found that only about 7% to 10% of the deer killed were juveniles. Hunters generally don’t take juvenile deer if they’re frequently encountering adults, since adult deer tend to be larger, offering more meat and bigger hides. Additionally, hunting increases mortality on a deer herd but doesn’t directly affect fertility, so deer populations experiencing hunting pressure end up with juvenile-skewed age structures. For these reasons, this low percentage of juvenile deer prior to European colonization indicates minimal hunting pressure on local herds. However, at a nearby site occupied during the 17th century—just after European colonization—between 22% and 31% of the deer hunted were juveniles, suggesting a substantial increase in hunting pressure.

Deer—particularly their skins—were commodified and sold in markets in the colonies initially and, by the 18th century, in Europe as well. Deer were now being exploited by traders, merchants and manufacturers desiring profit, not simply hunters desiring meat or leather.

    How white-tailed deer came back from the brink of extinction
    Given their abundance in American backyards, gardens and highway corridors these days, it may be surprising to learn that white-tailed deer were nearly extinct about a century ago. While they currently number somewhere in the range of 30 million to 35 million, at the turn of the 20th century, there were as few as 300,000 whitetails across the entire continent: just 1% of the current population. This near-disappearance of deer was much discussed at the time. In 1854, Henry David Thoreau had written that no deer had been hunted near Concord, Massachusetts, for a generation. In his famous “Walden,” he reported: “One man still preserves the horns of the last deer that was killed in this vicinity, and another has told me the particulars of the hunt in which his uncle was engaged. The hunters were formerly a numerous and merry crew here.” But what happened to white-tailed deer? What drove them nearly to extinction, and then what brought them back from the brink? As a historical ecologist and environmental archaeologist, I have made it my job to answer these questions. Over the past decade, I’ve studied white-tailed deer bones from archaeological sites across the eastern United States, as well as historical records and ecological data, to help piece together the story of this species. Precolonial rise of deer populations White-tailed deer have been hunted from the earliest migrations of people into North America, more than 15,000 years ago. The species was far from the most important food resource at that time, though. Archaeological evidence suggests that white-tailed deer abundance only began to increase after the extinction of megafauna species like mammoths and mastodons opened up ecological niches for deer to fill. Deer bones become very common in archaeological sites from about 6,000 years ago onward, reflecting the economic and cultural importance of the species for Indigenous peoples. Despite being so frequently hunted, deer populations do not seem to have appreciably declined due to Indigenous hunting prior to AD 1600. Unlike elk or sturgeon, whose numbers were reduced by Indigenous hunters and fishers, white-tailed deer seem to have been resilient to human predation. While archaeologists have found some evidence for human-caused declines in certain parts of North America, other cases are more ambiguous, and deer certainly remained abundant throughout the past several millennia. Human use of fire could partly explain why white-tailed deer may have been resilient to hunting. Indigenous peoples across North America have long used controlled burning to promote ecosystem health, disturbing old vegetation to promote new growth. Deer love this sort of successional vegetation for food and cover, and thus thrive in previously burned habitats. Indigenous people may have therefore facilitated deer population growth, counteracting any harmful hunting pressure. More research is needed, but even though some hunting pressure is evident, the general picture from the precolonial era is that deer seem to have been doing just fine for thousands of years.

    It's a regrettable reality that there is never time to cover all the interesting scientific stories we come across each month. In the past, we've featured year-end roundups of cool science stories wemissed. This year, we're experimenting with a monthly collection. May's list includes a nifty experiment to make a predicted effect of special relativity visible; a ping-pong playing robot that can return hits with 88 percent accuracy; and the discovery of the rare genetic mutation that makes orange cats orange, among other highlights.
    Special relativity made visible

    Perhaps the most well-known feature of Albert Einstein's special theory of relativity is time dilation and length contraction. In 1959, two physicists predicted another feature of relativistic motion: an object moving near the speed of light should also appear to be rotated. It's not been possible to demonstrate this experimentally, however—until now. Physicists at the Vienna University of Technology figured out how to reproduce this rotational effect in the lab using laser pulses and precision cameras, according to a paper published in the journal Communications Physics.
    They found their inspiration in art, specifically an earlier collaboration with an artist named Enar de Dios Rodriguez, who collaborated with VUT and the University of Vienna on a project involving ultra-fast photography and slow light. For this latest research, they used objects shaped like a cube and a sphere and moved them around the lab while zapping them with ultrashort laser pulses, recording the flashes with a high-speed camera.
    Getting the timing just right effectively yields similar results to a light speed of 2 m/s. After photographing the objects many times using this method, the team then combined the still images into a single image. The results: the cube looked twisted and the sphere's North Pole was in a different location—a demonstration of the rotational effect predicted back in 1959.

    Drumming chimpanzees

    Chimpanzees are known to "drum" on the roots of trees as a means of communication, often combining that action with what are known as "pant-hoot" vocalizations. Scientists have found that the chimps' drumming exhibits key elements of musical rhythm much like humans, according to  a paper published in the journal Current Biology—specifically non-random timing and isochrony. And chimps from different geographical regions have different drumming rhythms.
    Back in 2022, the same team observed that individual chimps had unique styles of "buttress drumming," which served as a kind of communication, letting others in the same group know their identity, location, and activity. This time around they wanted to know if this was also true of chimps living in different groups and whether their drumming was rhythmic in nature. So they collected video footage of the drumming behavior among 11 chimpanzee communities across six populations in East Africaand West Africa, amounting to 371 drumming bouts.
    Their analysis of the drum patterns confirmed their hypothesis. The western chimps drummed in regularly spaced hits, used faster tempos, and started drumming earlier during their pant-hoot vocalizations. Eastern chimps would alternate between shorter and longer spaced hits. Since this kind of rhythmic percussion is one of the earliest evolved forms of human musical expression and is ubiquitous across cultures, findings such as this could shed light on how our love of rhythm evolved.

    Distinctive styles of two jazz greats

    Jazz lovers likely need no introduction to Joe Pass and Wes Montgomery, 20th century guitarists who influenced generations of jazz musicians with their innovative techniques. Montgomery, for instance, didn't use a pick, preferring to pluck the strings with his thumb—a method he developed because he practiced at night after working all day as a machinist and didn't want to wake his children or neighbors. Pass developed his own range of picking techniques, including fingerpicking, hybrid picking, and "flat picking."
    Chirag Gokani and Preston Wilson, both with Applied Research Laboratories and the University of Texas, Austin, greatly admired both Pass and Montgomery and decided to explore the underlying the acoustics of their distinctive playing, modeling the interactions of the thumb, fingers, and pick with a guitar string. They described their research during a meeting of the Acoustical Society of America in New Orleans, LA.
    Among their findings: Montgomery achieved his warm tone by playing closer to the bridge and mostly plucking at the string. Pass's rich tone arose from a combination of using a pick and playing closer to the guitar neck. There were also differences in how much a thumb, finger, and pick slip off the string:  use of the thumbproduced more of a "pluck" compared to the pick, which produced more of a "strike." Gokani and Wilson think their model could be used to synthesize digital guitars with a more realistic sound, as well as helping guitarists better emulate Pass and Montgomery.
    Sounds of an ancient underground city

    Turkey is home to the underground city Derinkuyu, originally carved out inside soft volcanic rock around the 8th century BCE. It was later expanded to include four main ventilation channelsserving seven levels, which could be closed off from the inside with a large rolling stone. The city could hold up to 20,000 people and it  was connected to another underground city, Kaymakli, via tunnels. Derinkuyu helped protect Arab Muslims during the Arab-Byzantine wars, served as a refuge from the Ottomans in the 14th century, and as a haven for Armenians escaping persecution in the early 20th century, among other functions.

    The tunnels were rediscovered in the 1960s and about half of the city has been open to visitors since 2016. The site is naturally of great archaeological interest, but there has been little to no research on the acoustics of the site, particularly the ventilation channels—one of Derinkuyu's most unique features, according to Sezin Nas, an architectural acoustician at Istanbul Galata University in Turkey.  She gave a talk at a meeting of the Acoustical Society of America in New Orleans, LA, about her work on the site's acoustic environment.
    Nas analyzed a church, a living area, and a kitchen, measuring sound sources and reverberation patterns, among other factors, to create a 3D virtual soundscape. The hope is that a better understanding of this aspect of Derinkuyu could improve the design of future underground urban spaces—as well as one day using her virtual soundscape to enable visitors to experience the sounds of the city themselves.
    MIT's latest ping-pong robot
    Robots playing ping-pong have been a thing since the 1980s, of particular interest to scientists because it requires the robot to combine the slow, precise ability to grasp and pick up objects with dynamic, adaptable locomotion. Such robots need high-speed machine vision, fast motors and actuators, precise control, and the ability to make accurate predictions in real time, not to mention being able to develop a game strategy. More recent designs use AI techniques to allow the robots to "learn" from prior data to improve their performance.
    MIT researchers have built their own version of a ping-pong playing robot, incorporating a lightweight design and the ability to precisely return shots. They built on prior work developing the Humanoid, a small bipedal two-armed robot—specifically, modifying the Humanoid's arm by adding an extra degree of freedom to the wrist so the robot could control a ping-pong paddle. They tested their robot by mounting it on a ping-pong table and lobbing 150 balls at it from the other side of the table, capturing the action with high-speed cameras.

    The new bot can execute three different swing typesand during the trial runs it returned the ball with impressive accuracy across all three types: 88.4 percent, 89.2 percent, and 87.5 percent, respectively. Subsequent tweaks to theirrystem brought the robot's strike speed up to 19 meters per second, close to the 12 to 25 meters per second of advanced human players. The addition of control algorithms gave the robot the ability to aim. The robot still has limited mobility and reach because it has to be fixed to the ping-pong table but the MIT researchers plan to rig it to a gantry or wheeled platform in the future to address that shortcoming.
    Why orange cats are orange

    Cat lovers know orange cats are special for more than their unique coloring, but that's the quality that has intrigued scientists for almost a century. Sure, lots of animals have orange, ginger, or yellow hues, like tigers, orangutans, and golden retrievers. But in domestic cats that color is specifically linked to sex. Almost all orange cats are male. Scientists have now identified the genetic mutation responsible and it appears to be unique to cats, according to a paper published in the journal Current Biology.
    Prior work had narrowed down the region on the X chromosome most likely to contain the relevant mutation. The scientists knew that females usually have just one copy of the mutation and in that case have tortoiseshellcoloring, although in rare cases, a female cat will be orange if both X chromosomes have the mutation. Over the last five to ten years, there has been an explosion in genome resourcesfor cats which greatly aided the team's research, along with taking additional DNA samples from cats at spay and neuter clinics.

    From an initial pool of 51 candidate variants, the scientists narrowed it down to three genes, only one of which was likely to play any role in gene regulation: Arhgap36. It wasn't known to play any role in pigment cells in humans, mice, or non-orange cats. But orange cats are special; their mutationturns on Arhgap36 expression in pigment cells, thereby interfering with the molecular pathway that controls coat color in other orange-shaded mammals. The scientists suggest that this is an example of how genes can acquire new functions, thereby enabling species to better adapt and evolve.

    Not a Roman "massacre" after all

    Martin Smith

    In 1936, archaeologists excavating the Iron Age hill fort Maiden Castle in the UK unearthed dozens of human skeletons, all showing signs of lethal injuries to the head and upper body—likely inflicted with weaponry. At the time, this was interpreted as evidence of a pitched battle between the Britons of the local Durotriges tribe and invading Romans. The Romans slaughtered the native inhabitants, thereby bringing a sudden violent end to the Iron Age. At least that's the popular narrative that has prevailed ever since in countless popular articles, books, and documentaries.
    But a paper published in the Oxford Journal of Archaeology calls that narrative into question. Archaeologists at Bournemouth University have re-analyzed those burials, incorporating radiocarbon dating into their efforts. They concluded that those individuals didn't die in a single brutal battle. Rather, it was Britons killing other Britons over multiple generations between the first century BCE and the first century CE—most likely in periodic localized outbursts of violence in the lead-up to the Roman conquest of Britain. It's possible there are still many human remains waiting to be discovered at the site, which could shed further light on what happened at Maiden Castle.

In the past, we've featured year-end roundups of cool science stories we (almost) missed. This year, we're experimenting with a monthly collection. May's list includes a nifty experiment to make a predicted effect of special relativity visible; a ping-pong playing robot that can return hits with 88 percent accuracy; and the discovery of the rare genetic mutation that makes orange cats orange, among other highlights. Special relativity made visible Credit: TU Wien Perhaps the most well-known feature of Albert Einstein's special theory of relativity is time dilation and length contraction. In 1959, two physicists predicted another feature of relativistic motion: an object moving near the speed of light should also appear to be rotated. It's not been possible to demonstrate this experimentally, however—until now. Physicists at the Vienna University of Technology figured out how to reproduce this rotational effect in the lab using laser pulses and precision cameras, according to a paper published in the journal Communications Physics. They found their inspiration in art, specifically an earlier collaboration with an artist named Enar de Dios Rodriguez, who collaborated with VUT and the University of Vienna on a project involving ultra-fast photography and slow light. For this latest research, they used objects shaped like a cube and a sphere and moved them around the lab while zapping them with ultrashort laser pulses, recording the flashes with a high-speed camera. Getting the timing just right effectively yields similar results to a light speed of 2 m/s. After photographing the objects many times using this method, the team then combined the still images into a single image. The results: the cube looked twisted and the sphere's North Pole was in a different location—a demonstration of the rotational effect predicted back in 1959.

Chimpanzees are known to "drum" on the roots of trees as a means of communication, often combining that action with what are known as "pant-hoot" vocalizations (see above video). Scientists have found that the chimps' drumming exhibits key elements of musical rhythm much like humans, according to  a paper published in the journal Current Biology—specifically non-random timing and isochrony. And chimps from different geographical regions have different drumming rhythms. Back in 2022, the same team observed that individual chimps had unique styles of "buttress drumming," which served as a kind of communication, letting others in the same group know their identity, location, and activity. This time around they wanted to know if this was also true of chimps living in different groups and whether their drumming was rhythmic in nature. So they collected video footage of the drumming behavior among 11 chimpanzee communities across six populations in East Africa (Uganda) and West Africa (Ivory Coast), amounting to 371 drumming bouts. Their analysis of the drum patterns confirmed their hypothesis. The western chimps drummed in regularly spaced hits, used faster tempos, and started drumming earlier during their pant-hoot vocalizations. Eastern chimps would alternate between shorter and longer spaced hits. Since this kind of rhythmic percussion is one of the earliest evolved forms of human musical expression and is ubiquitous across cultures, findings such as this could shed light on how our love of rhythm evolved. DOI: Current Biology, 2025. 10.1016/j.cub.2025.04.019  (About DOIs). Distinctive styles of two jazz greats Jazz lovers likely need no introduction to Joe Pass and Wes Montgomery, 20th century guitarists who influenced generations of jazz musicians with their innovative techniques. Montgomery, for instance, didn't use a pick, preferring to pluck the strings with his thumb—a method he developed because he practiced at night after working all day as a machinist and didn't want to wake his children or neighbors. Pass developed his own range of picking techniques, including fingerpicking, hybrid picking, and "flat picking." Chirag Gokani and Preston Wilson, both with Applied Research Laboratories and the University of Texas, Austin, greatly admired both Pass and Montgomery and decided to explore the underlying the acoustics of their distinctive playing, modeling the interactions of the thumb, fingers, and pick with a guitar string. They described their research during a meeting of the Acoustical Society of America in New Orleans, LA. Among their findings: Montgomery achieved his warm tone by playing closer to the bridge and mostly plucking at the string. Pass's rich tone arose from a combination of using a pick and playing closer to the guitar neck. There were also differences in how much a thumb, finger, and pick slip off the string:  use of the thumb (Montgomery) produced more of a "pluck" compared to the pick (Pass), which produced more of a "strike." Gokani and Wilson think their model could be used to synthesize digital guitars with a more realistic sound, as well as helping guitarists better emulate Pass and Montgomery. Sounds of an ancient underground city Credit: Sezin Nas Turkey is home to the underground city Derinkuyu, originally carved out inside soft volcanic rock around the 8th century BCE. It was later expanded to include four main ventilation channels (and some 50,000 smaller shafts) serving seven levels, which could be closed off from the inside with a large rolling stone. The city could hold up to 20,000 people and it  was connected to another underground city, Kaymakli, via tunnels. Derinkuyu helped protect Arab Muslims during the Arab-Byzantine wars, served as a refuge from the Ottomans in the 14th century, and as a haven for Armenians escaping persecution in the early 20th century, among other functions. The tunnels were rediscovered in the 1960s and about half of the city has been open to visitors since 2016. The site is naturally of great archaeological interest, but there has been little to no research on the acoustics of the site, particularly the ventilation channels—one of Derinkuyu's most unique features, according to Sezin Nas, an architectural acoustician at Istanbul Galata University in Turkey.  She gave a talk at a meeting of the Acoustical Society of America in New Orleans, LA, about her work on the site's acoustic environment. Nas analyzed a church, a living area, and a kitchen, measuring sound sources and reverberation patterns, among other factors, to create a 3D virtual soundscape. The hope is that a better understanding of this aspect of Derinkuyu could improve the design of future underground urban spaces—as well as one day using her virtual soundscape to enable visitors to experience the sounds of the city themselves. MIT's latest ping-pong robot Robots playing ping-pong have been a thing since the 1980s, of particular interest to scientists because it requires the robot to combine the slow, precise ability to grasp and pick up objects with dynamic, adaptable locomotion. Such robots need high-speed machine vision, fast motors and actuators, precise control, and the ability to make accurate predictions in real time, not to mention being able to develop a game strategy. More recent designs use AI techniques to allow the robots to "learn" from prior data to improve their performance. MIT researchers have built their own version of a ping-pong playing robot, incorporating a lightweight design and the ability to precisely return shots. They built on prior work developing the Humanoid, a small bipedal two-armed robot—specifically, modifying the Humanoid's arm by adding an extra degree of freedom to the wrist so the robot could control a ping-pong paddle. They tested their robot by mounting it on a ping-pong table and lobbing 150 balls at it from the other side of the table, capturing the action with high-speed cameras. The new bot can execute three different swing types (loop, drive, and chip) and during the trial runs it returned the ball with impressive accuracy across all three types: 88.4 percent, 89.2 percent, and 87.5 percent, respectively. Subsequent tweaks to theirrystem brought the robot's strike speed up to 19 meters per second (about 42 MPH), close to the 12 to 25 meters per second of advanced human players. The addition of control algorithms gave the robot the ability to aim. The robot still has limited mobility and reach because it has to be fixed to the ping-pong table but the MIT researchers plan to rig it to a gantry or wheeled platform in the future to address that shortcoming. Why orange cats are orange Credit: Astropulse/CC BY-SA 3.0 Cat lovers know orange cats are special for more than their unique coloring, but that's the quality that has intrigued scientists for almost a century. Sure, lots of animals have orange, ginger, or yellow hues, like tigers, orangutans, and golden retrievers. But in domestic cats that color is specifically linked to sex. Almost all orange cats are male. Scientists have now identified the genetic mutation responsible and it appears to be unique to cats, according to a paper published in the journal Current Biology. Prior work had narrowed down the region on the X chromosome most likely to contain the relevant mutation. The scientists knew that females usually have just one copy of the mutation and in that case have tortoiseshell (partially orange) coloring, although in rare cases, a female cat will be orange if both X chromosomes have the mutation. Over the last five to ten years, there has been an explosion in genome resources (including complete sequenced genomes) for cats which greatly aided the team's research, along with taking additional DNA samples from cats at spay and neuter clinics. From an initial pool of 51 candidate variants, the scientists narrowed it down to three genes, only one of which was likely to play any role in gene regulation: Arhgap36. It wasn't known to play any role in pigment cells in humans, mice, or non-orange cats. But orange cats are special; their mutation (sex-linked orange) turns on Arhgap36 expression in pigment cells (and only pigment cells), thereby interfering with the molecular pathway that controls coat color in other orange-shaded mammals. The scientists suggest that this is an example of how genes can acquire new functions, thereby enabling species to better adapt and evolve.

Not a Roman "massacre" after all Credit: Martin Smith In 1936, archaeologists excavating the Iron Age hill fort Maiden Castle in the UK unearthed dozens of human skeletons, all showing signs of lethal injuries to the head and upper body—likely inflicted with weaponry. At the time, this was interpreted as evidence of a pitched battle between the Britons of the local Durotriges tribe and invading Romans. The Romans slaughtered the native inhabitants, thereby bringing a sudden violent end to the Iron Age. At least that's the popular narrative that has prevailed ever since in countless popular articles, books, and documentaries. But a paper published in the Oxford Journal of Archaeology calls that narrative into question. Archaeologists at Bournemouth University have re-analyzed those burials, incorporating radiocarbon dating into their efforts. They concluded that those individuals didn't die in a single brutal battle. Rather, it was Britons killing other Britons over multiple generations between the first century BCE and the first century CE—most likely in periodic localized outbursts of violence in the lead-up to the Roman conquest of Britain. It's possible there are still many human remains waiting to be discovered at the site, which could shed further light on what happened at Maiden Castle.

    Researchers recovered this face-shaped rock from the San Lázaro rock-shelter in central Spain in 2022 © Álvarez-Alonso et al

    While digging inside a cave in the Spanish city of Segovia, archaeologists uncovered an unusual rock. The hand-sized stone naturally resembled an elongated face, and featured a spot of red pigment made from ochre right on the tip of what may be considered its nose.  “We were all thinking the same thing and looking at each other because of its shape: we were all thinking, ‘This looks like a face,’” David Álvarez Alonso, an archaeologist at Complutense University in Madrid who was part of the dig, told The Guardian. Álvarez Alonso and his colleagues spent the next three years studying this bizarre rock. The researchers posit that 43,000 years ago, a Neanderthal dipped their finger in ochre and pressed it onto the stone’s central ridge—leaving behind what is now considered to be the world’s oldest complete human fingerprint. It’s an intriguing finding that could have significant implications, but some experts would like to see more evidence to support this hypothesis. 

    The team published its findings in the journal Archaeological and Anthropological Sciences on Saturday, May 24. In the paper, the archaeologists state that the “strategic position” of the dot suggests it is evidence of Neanderthals’ “symbolic behavior.” In other words, it’s a piece of art that “could represent one of the earliest human face symbolizations in prehistory.” “The fact that thewas selected because of its appearance and then marked with ochre shows that there was a human mind capable of symbolizing, imagining, idealizing and projecting his or her thoughts on an object,” the researchers write.  Whether Neanderthals were capable of making art is a subject of ongoing debate, co-author María de Andrés-Herrero, a professor of prehistory at Complutense University, told the BBC. But over the past decade, a growing body of evidence has led many experts to believe that artistic expression emerged earlier in human evolution than previously thought. 

    The authors of this new study think their stone adds to this evidence. To reach this conclusion, they first needed more data to support the idea that this ancient artist had actually experienced pareidolia: seeing a face in an inanimate object. To that end, they generated a 3D model of the stone’s surface and measured the distances between its features, finding that the red dot—or nose—was placed such that it accurately resembled an actual nose on a human face.  Then, the researchers enlisted the help of geologists to characterize the red dot, confirming that it was made with ochre. Forensic police experts then used multispectral analysis—a technique that can reveal details invisible to the naked eye—to confirm that the red dot had been applied with a fingertip. Their analysis uncovered a fingerprint that could have belonged to an adult male Neanderthal inside the dot. 

    “Once we had that and all the other pieces, context and information, we advanced the theory that this could be a pareidolia, which then led to a human intervention in the form of the red dot,” Álvarez Alonso told The Guardian. “Without that red dot, you can’t make any claims about the object.” But Gilliane Monnier, a professor of anthropology at the University of Minnesota who studies Neanderthal behavior, is not totally convinced by the researchers’ findings. “The fact that there are these natural depressions—and that we can measure the distance between them and argue that it’s a face—that’s all well and good,” Monnier, who wasn’t involved in the study, told Gizmodo. “But that doesn’t give us any indication that the Neanderthals whosaw a face in that.” 

    What’s more, she is skeptical of the researchers’ claim that the red dot was actually made with a human fingertip. It’s possible, she said, that the coloring and fingerprint-like ridges formed naturally. “I would be interested in seeing an explanation by a geologist—someone trained in geology—saying the likelihood of this forming by natural, geological or geomicrobial processes is a very low likelihood,” Monnier said.  The researchers, too, acknowledge that “it is unlikely that all doubts surrounding this hypothesis can be fully dispelled,” and state that the pareidolia hypothesis should not be seen as a definitive claim, but rather a possible explanation for this object based on the evidence.

    So it’s hard to say whether this study clarifies or complicates our understanding of how the human mind evolved the ability to create art. The face-shaped rock is an intriguing piece of the puzzle, but more research is needed to figure out where it fits.

    In 1917, two US submarines collided off the coast of San Diego and submarine USS F-1 sank to the bottom of the Pacific Ocean, along with 19 crew members aboard. The horrible accident, whose wreckage was discovered in 1975, represents the US Naval Submarine Force’s first wartime submarine loss. Now, researchers from Woods Hole Oceanographic Institution have captured new footage of the 1,300 feet-deep underwater archaeological site.
    “They were technical dives requiring specialized expertise and equipment,” Anna Michel, a co-lead of the expedition and chief scientist at the National Deep Submergence Facility, said in a statement. “We were careful and methodical in surveying these historical sites so that we could share these stunning images, while also maintaining the reverence these sites deserve.”

    The high-definition imagining and mapping of the USS F-1 took place during a deep-sea training and engineering mission in February and March. The missions aimed to train future submersible pilots and test the human-occupied vehicle Alvin and autonomous underwater vehicle Sentry. 
    The team captured never-seen-before images and videos and conducted a sonar survey, which essentially consists of mapping a region by shooting sound waves at it and registering the echo. Imaging specialists combined the 2D images into a 3D model of the wreck—a technique called photogrammetry. Using photogrammetry reveals measurements not just of the submarine but of the marine life that over the past century has claimed the vessel as its own.

    “As a Navy veteran, making this dive—together with another Navy veteran and a Navy historian—was a solemn privilege,” said Office of Naval Research Program Officer Rob Sparrock, who was in Alvin when it went down to the wreck. “There was time to contemplate the risks that all mariners, past and present, face. It also reminded me of the importance of these training dives, which leverage the knowledge from past dives, lessons learned and sound engineering.”
    The researchers also investigated a Navy torpedo bomber training aircraft that went down in the region in 1950. After the dives, they held a remembrance ceremony aboard the research vessel Atlantis during which a bell rang once for each of the crew members lost in 1917. 
    “History and archaeology are all about people and we felt it was important to read their names aloud,” said Naval History and Heritage Command Underwater Archaeologist Brad Krueger, who also dove in Alvin. “The Navy has a solemn responsibility to ensure the legacies of its lost Sailors are remembered.”

Get the Popular Science daily newsletter💡 Breakthroughs, discoveries, and DIY tips sent every weekday. In 1917, two US submarines collided off the coast of San Diego and submarine USS F-1 sank to the bottom of the Pacific Ocean, along with 19 crew members aboard. The horrible accident, whose wreckage was discovered in 1975, represents the US Naval Submarine Force’s first wartime submarine loss. Now, researchers from Woods Hole Oceanographic Institution have captured new footage of the 1,300 feet-deep underwater archaeological site. “They were technical dives requiring specialized expertise and equipment,” Anna Michel, a co-lead of the expedition and chief scientist at the National Deep Submergence Facility, said in a statement. “We were careful and methodical in surveying these historical sites so that we could share these stunning images, while also maintaining the reverence these sites deserve.” The high-definition imagining and mapping of the USS F-1 took place during a deep-sea training and engineering mission in February and March. The missions aimed to train future submersible pilots and test the human-occupied vehicle Alvin and autonomous underwater vehicle Sentry.  The team captured never-seen-before images and videos and conducted a sonar survey, which essentially consists of mapping a region by shooting sound waves at it and registering the echo. Imaging specialists combined the 2D images into a 3D model of the wreck—a technique called photogrammetry. Using photogrammetry reveals measurements not just of the submarine but of the marine life that over the past century has claimed the vessel as its own.  Photogrammetric reconstruction of the submarine USS F-1 showing the sub’s stern and propeller.

It also reminded me of the importance of these training dives, which leverage the knowledge from past dives, lessons learned and sound engineering.” The researchers also investigated a Navy torpedo bomber training aircraft that went down in the region in 1950. After the dives, they held a remembrance ceremony aboard the research vessel Atlantis during which a bell rang once for each of the crew members lost in 1917.  “History and archaeology are all about people and we felt it was important to read their names aloud,” said Naval History and Heritage Command Underwater Archaeologist Brad Krueger, who also dove in Alvin. “The Navy has a solemn responsibility to ensure the legacies of its lost Sailors are remembered.”

    Humans used whale bones to make tools 20,000 years ago

    Beached whales provided Stone Age humans with bones to fashion into hunting weapons

    Researchers have identified the world’s oldest known whale bone tools. This spear point made of gray whale bone, from a French rock–shelter, dates to between 18,000 and 17,500 years old.

    Western Europeans crafted hunting weapons out of bones from whales stranded on the Atlantic shoreline between 20,000 and 14,000 years ago, researchers report May 27 in Nature Communications.
    Previously excavated finds at Stone Age cave and rock–shelter sites running from northwestern Spain to southwestern France, some located as far as about 300 kilometers inland, represent the oldest known examples of whale bone tools, say archaeologist Jean-Marc Pétillon of the University of Toulouse Jean Jaurès, France, and colleagues. Implements made of whale bones in other parts of the world, such as the South Pacific islands, date to no more than several thousand years old.

    Prehistoric stone tools are among some of the oldest and important pieces of evidence we have of a time when our species began to evolve a higher level of intelligence. Many of these tools were also made from animal bones–including the bones of some of the biggest animals on the planet. New research finds that humans living up to 20,000 years ago may have been making tools out of whale bones. The discovery not only adds more to the story of early human tool use, but gives a glimpse into ancient whale ecology. The findings are detailed in a study published May 27 in the journal Nature Communications.
    “That humans frequented the seashore, and took advantage of its resources, is probably as old as humankind,” Jean-Marc Pétillon, an archaeologist at the Université Toulouse Jean Jaurès in France and study co-author, tells Popular Science. “There is evidence of whale scavenging at the site of Dungo 5 in Angola dating to 1 million years.”

    By land and sea
    For our Paleolithic ancestors living in coastal areas, the sturdy bones of large whales were potentially an excellent resource for various tools. However, many prehistoric coastal archaeological sites are fragile and are at risk of rising sea levels, making reconstructing the past interactions between marine mammals and humans a challenge for scientists..  
    “The tools were dated between 20,000 and 16,000 years beforepresent, a period way before the invention of agriculture, and during which all human groups in the world lived a life of nomadic hunter-gatherers,” says Pétillon. “Climatically, this is the last part of the last glaciation, with a climate much colder than today.”
    That colder climate brought a sea level that was roughly almost 400 feet lower than it is today. With this change in sea level, we have no direct evidence of the human occupations on the shore, since the rise in sea level either wiped them out or the settlements lay buried under 300 or so feet of water.

    With this lack of evidence Paleolithic people have historically been viewed as inland hunters. Those living in present day western Europe would have hunted red deer, reindeer, bison, horse, and ibex. While they did hunt inland, there is a growing body of evidence from the last 20 years showing that they also took advantage of the Paleolithic seashore.
    “There are studies showing that people also gathered seashells, hunted seabirds, fished marine fish, etc., as a complement to terrestrial diet, and these studies were made possible because Paleolithic people carried remains of marine origin away from the seashore, into inland sites,” explains Pétillon. “Our study adds whales to the lot. It is one more contribution showing that Late Paleolithic humans also regularly frequented the seashore and used its resources.”
    Ancient giants
    In the new study, the team analyzed 83 bone tools that were excavated from sites around Spain’s Bay of Biscay and 90 additional bones uncovered from Santa Catalina Cave in Spain. They used mass spectrometry and radiocarbon dating to identify which species the bones belonged to and estimate the age of  the samples. 
    The bones come from at least five species of large whales–sperm, fin, blue, gray, and either right whales or bowheads. The latter two species are indistinguishable using this technique. The oldest whale specimens are dated to roughly 19,000 to 20,000 years ago, representing some of the earliest known evidence of humans using the remains of whales to make tools. Some of the whale bone points themselves were over 15 inches long.

    “Most of the objects made of whale bone are projectile points, part of the hunting equipment. They can be very long and thick, and were probably hafted on spear-style projectiles rather than arrows,” says Pétillon. “The main raw material used to manufacture projectile points at that period is antler, because it is less brittle and more pliable than bone, but whale bone was preferred in certain cases probably because of its large dimensions.”
    The ocean’s bounty
    Most of these whale species identified in this study are still found in the Bay of Biscay and northeastern North Atlantic to this day. However, gray whales are now primarily limited to the North Pacific Ocean and Arctic. Additional chemical data from the tools also suggests that the feeding habits of the ancient whales were slightly different than those living today. According to the authors, this is likely due to behavioral or environmental changes. That the whales in the area have stayed relatively the same was particularly intriguing for Pétillon.
    “What was more surprising to me—as an archeologist more accustomed to terrestrial faunas—was that these whale species remained the same despite the great environmental difference between the Late Pleistocene and today,” he says. “In the same period, continental faunas are very different: the ungulates hunted include reindeer, saiga antelopes, bison, etc., all disappeared from Western Europe today.”
    Importantly, the findings here do not imply that active whaling was occurring. The techniques at the time would not allow humans to hunt sperm, blue, or fin whales and the team believes that these populations took advantage of whale strandings to harvest the bones for tools. 
    “The earliest evidence of active whaling is much younger, around 6,000before present in Koreaand maybe around 5,000 before present in Europe,” says Pétillon.
    Future studies could look at the systematic way that these ancient Atlantic Europeans systematically used the seashore and how they developed their ocean hunting techniques.

  • 14 of the most significant archaeological sites in the US

    The US is less than 250 years old, but some of its most important archaeological sites are older than the Viking seafarers, the Roman Empire, and the pyramids.Many help tell the story of how the first humans came to North America. It's still a mystery exactly how and when people arrived, though it's widely believed they crossed the Bering Strait at least 15,000 years ago."As we get further back in time, as we get populations that are smaller and smaller, finding these places and interpreting them becomes increasingly difficult," archaeologist Kenneth Feder told Business Insider. He's the author of "Ancient America: Fifty Archaeological Sites to See for Yourself."Some sites, like White Sands and Cooper's Ferry, have skeptics about the accuracy of their age. Still, they contribute to our understanding of some of the earliest Americans.Others are more recent and highlight the different cultures that were spreading around the country, with complex buildings and illuminating pictographs.Many of these places are open to the public, so you can see the US' ancient history for yourself.

    Prehistoric camels, mammoths, and giant sloths once roamed what's now New Mexico, when it was greener and damper.As the climate warmed around 11,000 years ago, the water of Lake Otero receded, revealing footprints of humans who lived among these extinct animals. Some even seemed to be following a sloth, offering a rare glimpse into ancient hunters' behavior.Recent research puts some of these fossilized footprints at between 21,000 and 23,000 years old. If the dates are accurate, the prints would predate other archaeological sites in the US, raising intriguing questions about who these people were and how they arrived in the Southwestern state."Where are they coming from?" Feder said. "They're not parachute dropping in New Mexico. They must have come from somewhere else, which means there are even older sites." Archaeologists simply haven't found them yet.While visitors can soak in the sight of the eponymous white sands, the footprints are currently off-limits.

    In the 1970s, archaeologist James M. Adovasio sparked a controversy when he and his colleagues suggested stone tools and other artifacts found in southwestern Pennsylvania belonged to humans who had lived in the area 16,000 years ago.For decades, scientists had been finding evidence of human habitation that all seemed to be around 12,000 to 13,000 years old, belonging to the Clovis culture. They were long believed to have been the first to cross the Bering land bridge. Humans who arrived in North America before this group are often referred to as pre-Clovis.At the time, skeptics said that the radiocarbon dating evidence was flawed, AP News reported in 2016. In the years since, more sites that appear older than 13,000 years have been found across the US.Feder said Adovasio meticulously excavated the site, but there's still no clear consensus about the age of the oldest artifacts. Still, he said, "that site is absolutely a major, important, significant site." It helped archaeologists realize humans started arriving on the continent before the Clovis people.The dig itself is on display at the Heinz History Center, allowing visitors to see an excavation in person.

    One site that's added intriguing evidence to the pre-Clovis theory is located in western Idaho. Humans living there left stone tools and charred bones in a hearth between 14,000 and 16,000 years ago, according to radiocarbon dating. Other researchers put the dates closer to 11,500 years ago.These stemmed tools are different from the Clovis fluted projectiles, researchers wrote in a 2019 Science Advances paper.Some scientists think humans may have been traveling along the West Coast at this time, when huge ice sheets covered Alaska and Canada. "People using boats, using canoes could hop along that coast and end up in North America long before those glacial ice bodies decoupled," Feder said.Cooper's Ferry is located on traditional Nez Perce land, which the Bureau of Land Management holds in public ownership.

    In the early 1980s, former Navy SEAL Buddy Page alerted paleontologists and archaeologists to a sinkhole nicknamed "Booger Hole" in the Aucilla River. There, the researchers found mammoth and mastodon bones and stone tools.They also discovered a mastodon tusk with what appeared to be cut marks believed to be made by a tool. Other scientists have returned to the site more recently, bringing up more bones and tools. They used radiocarbon dating, which established the site as pre-Clovis."The stone tools and faunal remains at the site show that at 14,550 years ago, people knew how to find game, fresh water and material for making tools," Michael Waters, one of the researchers, said in a statement in 2016. "These people were well-adapted to this environment."Since the site is both underwater and on private property, it's not open to visitors.

    Scientists study coprolites, or fossilized poop, to learn about the diets of long-dead animals. Mineralized waste can also reveal much more. In 2020, archaeologist Dennis Jenkins published a paper on coprolites from an Oregon cave that were over 14,000 years old.Radiocarbon dating gave the trace fossils' age, and genetic tests suggested they belonged to humans. Further analysis of coprolites added additional evidence that a group had been on the West Coast 1,000 years before the Clovis people arrived.Located in southcentral Oregon, the caves appear to be a piece of the puzzle indicating how humans spread throughout the continent thousands of years ago.The federal Bureau of Land Management owns the land where the caves are found, and they are listed on the National Register of Historic Places.

    Whenever people arrived in the Americas, they crossed from Siberia into Beringia, an area of land and sea between Russia and Canada and Alaska. Now it's covered in water, but there was once a land bridge connecting them.The site in Alaska with the oldest evidence of human habitation is Swan Point, in the state's eastern-central region. In addition to tools and hearths dating back 14,000 years, mammoth bones have been found there.Researchers think this area was a kind of seasonal hunting camp. As mammoths returned during certain times of the years, humans would track them and kill them, providing plentiful food for the hunter-gatherers.While Alaska may have a wealth of archaeological evidence of early Americans, it's also a difficult place to excavate. "Your digging season is very narrow, and it's expensive," Feder said. Some require a helicopter to reach, for example.

    In 1929, 19-year-old James Ridgley Whiteman found mammoth bones along with fluted projectile points near Clovis, New Mexico. The Clovis people who made these tools were named for this site.Researchers studying the site began to realize the artifacts found at the site belonged to different cultures. Clovis points are typically larger than Folsom flutes, which were first found at another archaeological site in New Mexico.For decades after Whiteman's discovery, experts thought the Clovis people were the first to cross the Bering land bridge from Asia around 13,000 years ago. Estimates for humans' arrival is now thought to be at least 15,000 years ago.Eastern New Mexico University's Blackwater Draw Museum grants access to the archaeological site between April and October.

    One reason the dates of human occupation in North America is so contentious is that very few ancient remains have been found. Among the oldest is a child from Upward Sun River, or Xaasaa Na', in Central Alaska.Archaeologists found the bones of the child in 2013. Local indigenous groups refer to her as Xach'itee'aanenh t'eede gay, or Sunrise Girl-Child. Genetic testing revealed the 11,300-year-old infant belonged to a previously unknown Native American population, the Ancient Beringians.Based on the child's genetic information, researchers learned that she was related to modern Native Americans but not directly. Their common ancestors started becoming genetically isolated 25,000 years ago before dividing into two groups after a few thousand years: the Ancient Berignians and the ancestors of modern Native Americans.According to this research, it's possible humans reached Alaska roughly 20,000 years ago.

    Stretching over 80 feet long and 5 feet tall, the rows of curved mounds of Poverty Point are a marvel when viewed from above. Over 3,000 years ago, hunter-gatherers constructed them out of tons of soil. Scientists aren't sure exactly why people built them, whether they were ceremonial or a display of status.The artifacts various groups left behind indicate the site was used off and on for hundreds of years and was a meeting point for trading. People brought tools and rocks from as far as 800 miles away. Remains of deer, fish, frogs, alligators, nuts, grapes, and other food have given archaeologists insights into their diets and daily lives.You can see the World Heritage Site for yourself year-round.

    Though remote, the multicolored walls of Horseshoe Canyon have long attracted visitors. Some of its artifacts date back to between 9,000 and 7,000 BCE, but its pictographs are more recent. Some tests date certain sections to around 2,000 to 900 years ago.The four galleries contain life-sized images of anthropomorphic figures and animals in what's known as the Barrier Canyon style. Much of this art is found in Utah, produced by the Desert Archaic culture.The pictographs may have spiritual and practical significance but also help capture a time when groups were meeting and mixing, according to the Natural History Museum of Utah.It's a difficult trek to get to the pictographsbut are amazing to view in person, Feder said. "These are creative geniuses," he said of the artists.

    Situated in the Navajo Nation, Canyon de Chelly has gorgeous desert views and thousands of years of human history. Centuries ago, Ancestral Pueblo and Hopi groups planted crops, created pictographs, and built cliff dwellings.Over 900 years ago, Puebloan people constructed the White House, named for the hue of its clay. Its upper floors sit on a sandstone cliff, with a sheer drop outside the windows.Navajo people, also known as Diné, still live in Canyon de Chelly. Diné journalist Alastair Lee Bitsóí recently wrote about visiting some of the sacred and taboo areas. They include Tsé Yaa Kin, where archaeologists found human remains.In the 1860s, the US government forced 8,000 Navajo to relocate to Fort Sumner in New Mexico. The deadly journey is known as the "Long Walk." Eventually, they were able to return, though their homes and crops were destroyed.A hike to the White House is the only one open to the public without a Navajo guide or NPS ranger.

    In the early 1900s, two women formed the Colorado Cliff Dwelling Association, hoping to preserve the ruins in the state's southwestern region. A few years later, President Theodore Roosevelt signed a bill designating Mesa Verde as the first national park meant to "preserve the works of man."Mesa Verde National Park holds hundreds of dwellings, including the sprawling Cliff Palace. It has over 100 rooms and nearly two dozen kivas, or ceremonial spaces.Using dendrochronology, or tree-ring dating, archaeologists learned when Ancestral Pueblo people built some of these structures and that they migrated out of the area by the 1300s.Feder said it's his favorite archaeological site he's visited. "You don't want to leave because you can't believe it's real," he said.Tourists can view many of these dwellings from the road, but some are also accessible after a bit of a hike. Some require extra tickets and can get crowded, Feder said.

    Cahokia, Illinois

    Cahokia has been called one of North America's first cities. Not far from present-day St. Louis, an estimated 10,000 to 20,000 people lived in dense settlements roughly 1,000 years ago. Important buildings sat atop large mounds, which the Mississippians built by hand, The Guardian reported.At the time, it was thriving with hunters, farmers, and artisans. "It's an agricultural civilization," Feder said. "It's a place where raw materials from a thousand miles away are coming in." Researchers have also found mass graves, potentially from human sacrifices.The inhabitants built circles of posts, which one archaeologist later referred to as "woodhenges," as a kind of calendar. At the solstices, the sun would rise or set aligned with different mounds.After a few hundred years, Cahokia's population declined and disappeared by 1350. Its largest mound remains, and some aspects have been reconstructed.While Cahokia is typically open to the public, parts are currently closed for renovations.

    Perched on a limestone cliff in Camp Verde, Arizona, this site is an apartment, not a castle, and is unrelated to the Aztec ruler Montezuma.The Sinagua people engineered the five-story, 20-room building around 1100. It curves to follow the natural line of the cliff, which would have been more difficult than simply making a straight building, Feder said."These people were architects," he said. "They had a sense of beauty."The inhabitants were also practical, figuring out irrigation systems and construction techniques, like thick walls and shady spots, to help them survive the hot, dry climate.Feder said the dwelling is fairly accessible, with a short walk along a trail to view it, though visitors can't go inside the building itself.

    14 of the most significant archaeological sites in the US
    The US is less than 250 years old, but some of its most important archaeological sites are older than the Viking seafarers, the Roman Empire, and the pyramids.Many help tell the story of how the first humans came to North America. It's still a mystery exactly how and when people arrived, though it's widely believed they crossed the Bering Strait at least 15,000 years ago."As we get further back in time, as we get populations that are smaller and smaller, finding these places and interpreting them becomes increasingly difficult," archaeologist Kenneth Feder told Business Insider. He's the author of "Ancient America: Fifty Archaeological Sites to See for Yourself."Some sites, like White Sands and Cooper's Ferry, have skeptics about the accuracy of their age. Still, they contribute to our understanding of some of the earliest Americans.Others are more recent and highlight the different cultures that were spreading around the country, with complex buildings and illuminating pictographs.Many of these places are open to the public, so you can see the US' ancient history for yourself. White Sands National Park, New Mexico Footprints at White Sands. National Park Service Prehistoric camels, mammoths, and giant sloths once roamed what's now New Mexico, when it was greener and damper.As the climate warmed around 11,000 years ago, the water of Lake Otero receded, revealing footprints of humans who lived among these extinct animals. Some even seemed to be following a sloth, offering a rare glimpse into ancient hunters' behavior.Recent research puts some of these fossilized footprints at between 21,000 and 23,000 years old. If the dates are accurate, the prints would predate other archaeological sites in the US, raising intriguing questions about who these people were and how they arrived in the Southwestern state."Where are they coming from?" Feder said. "They're not parachute dropping in New Mexico. They must have come from somewhere else, which means there are even older sites." Archaeologists simply haven't found them yet.While visitors can soak in the sight of the eponymous white sands, the footprints are currently off-limits. Meadowcroft Rockshelter, Pennsylvania The archeological dig at the Meadowcroft National Historic Site in 2013. AP Photo/Keith Srakocic In the 1970s, archaeologist James M. Adovasio sparked a controversy when he and his colleagues suggested stone tools and other artifacts found in southwestern Pennsylvania belonged to humans who had lived in the area 16,000 years ago.For decades, scientists had been finding evidence of human habitation that all seemed to be around 12,000 to 13,000 years old, belonging to the Clovis culture. They were long believed to have been the first to cross the Bering land bridge. Humans who arrived in North America before this group are often referred to as pre-Clovis.At the time, skeptics said that the radiocarbon dating evidence was flawed, AP News reported in 2016. In the years since, more sites that appear older than 13,000 years have been found across the US.Feder said Adovasio meticulously excavated the site, but there's still no clear consensus about the age of the oldest artifacts. Still, he said, "that site is absolutely a major, important, significant site." It helped archaeologists realize humans started arriving on the continent before the Clovis people.The dig itself is on display at the Heinz History Center, allowing visitors to see an excavation in person. Cooper's Ferry, Idaho Excavators at Cooper's Ferry in 2013. Loren Davis/Oregon State University One site that's added intriguing evidence to the pre-Clovis theory is located in western Idaho. Humans living there left stone tools and charred bones in a hearth between 14,000 and 16,000 years ago, according to radiocarbon dating. Other researchers put the dates closer to 11,500 years ago.These stemmed tools are different from the Clovis fluted projectiles, researchers wrote in a 2019 Science Advances paper.Some scientists think humans may have been traveling along the West Coast at this time, when huge ice sheets covered Alaska and Canada. "People using boats, using canoes could hop along that coast and end up in North America long before those glacial ice bodies decoupled," Feder said.Cooper's Ferry is located on traditional Nez Perce land, which the Bureau of Land Management holds in public ownership. Page-Ladson, Florida Divers search in the sediment at the Page-Ladson site. Texas A&M University via Getty Images In the early 1980s, former Navy SEAL Buddy Page alerted paleontologists and archaeologists to a sinkhole nicknamed "Booger Hole" in the Aucilla River. There, the researchers found mammoth and mastodon bones and stone tools.They also discovered a mastodon tusk with what appeared to be cut marks believed to be made by a tool. Other scientists have returned to the site more recently, bringing up more bones and tools. They used radiocarbon dating, which established the site as pre-Clovis."The stone tools and faunal remains at the site show that at 14,550 years ago, people knew how to find game, fresh water and material for making tools," Michael Waters, one of the researchers, said in a statement in 2016. "These people were well-adapted to this environment."Since the site is both underwater and on private property, it's not open to visitors. Paisley Caves, Oregon One of the Paisley Caves near Paisley, Oregon. AP Photo/Jeff Barnard Scientists study coprolites, or fossilized poop, to learn about the diets of long-dead animals. Mineralized waste can also reveal much more. In 2020, archaeologist Dennis Jenkins published a paper on coprolites from an Oregon cave that were over 14,000 years old.Radiocarbon dating gave the trace fossils' age, and genetic tests suggested they belonged to humans. Further analysis of coprolites added additional evidence that a group had been on the West Coast 1,000 years before the Clovis people arrived.Located in southcentral Oregon, the caves appear to be a piece of the puzzle indicating how humans spread throughout the continent thousands of years ago.The federal Bureau of Land Management owns the land where the caves are found, and they are listed on the National Register of Historic Places. Swan Point, Alaska Excavators working at the Swan Point site in June 2016. Charles Holmes/University of Alaska, Fairbanks Whenever people arrived in the Americas, they crossed from Siberia into Beringia, an area of land and sea between Russia and Canada and Alaska. Now it's covered in water, but there was once a land bridge connecting them.The site in Alaska with the oldest evidence of human habitation is Swan Point, in the state's eastern-central region. In addition to tools and hearths dating back 14,000 years, mammoth bones have been found there.Researchers think this area was a kind of seasonal hunting camp. As mammoths returned during certain times of the years, humans would track them and kill them, providing plentiful food for the hunter-gatherers.While Alaska may have a wealth of archaeological evidence of early Americans, it's also a difficult place to excavate. "Your digging season is very narrow, and it's expensive," Feder said. Some require a helicopter to reach, for example. Blackwater Draw, New Mexico A palaeontologist excavating a mammoth in Portales, New Mexico, circa 1960.

A few years later, President Theodore Roosevelt signed a bill designating Mesa Verde as the first national park meant to "preserve the works of man."Mesa Verde National Park holds hundreds of dwellings, including the sprawling Cliff Palace. It has over 100 rooms and nearly two dozen kivas, or ceremonial spaces.Using dendrochronology, or tree-ring dating, archaeologists learned when Ancestral Pueblo people built some of these structures and that they migrated out of the area by the 1300s.Feder said it's his favorite archaeological site he's visited. "You don't want to leave because you can't believe it's real," he said.Tourists can view many of these dwellings from the road, but some are also accessible after a bit of a hike. Some require extra tickets and can get crowded, Feder said. Cahokia, Illinois A mound at Cahokia in Illinois. Matt Gush/Shutterstock Cahokia has been called one of North America's first cities. Not far from present-day St. Louis, an estimated 10,000 to 20,000 people lived in dense settlements roughly 1,000 years ago. Important buildings sat atop large mounds, which the Mississippians built by hand, The Guardian reported.At the time, it was thriving with hunters, farmers, and artisans. "It's an agricultural civilization," Feder said. "It's a place where raw materials from a thousand miles away are coming in." Researchers have also found mass graves, potentially from human sacrifices.The inhabitants built circles of posts, which one archaeologist later referred to as "woodhenges," as a kind of calendar. At the solstices, the sun would rise or set aligned with different mounds.After a few hundred years, Cahokia's population declined and disappeared by 1350. Its largest mound remains, and some aspects have been reconstructed.While Cahokia is typically open to the public, parts are currently closed for renovations. Montezuma Castle, Arizona Montezuma Castle, a cliff dwelling, in Arizona.

It curves to follow the natural line of the cliff, which would have been more difficult than simply making a straight building, Feder said."These people were architects," he said. "They had a sense of beauty."The inhabitants were also practical, figuring out irrigation systems and construction techniques, like thick walls and shady spots, to help them survive the hot, dry climate.Feder said the dwelling is fairly accessible, with a short walk along a trail to view it, though visitors can't go inside the building itself.
