Blue-eyed humans have a single, common ancestor

Blue-eyed humans have a single, common ancestor

People with blue eyes have a single, common ancestor, according to new research. A team of scientists has tracked down a genetic mutation that leads to blue eyes. The mutation occurred between 6,000 and 10,000 years ago. Before then, there were no blue eyes.

“Originally, we all had brown eyes,” said Hans Eiberg from the Department of Cellular and Molecular Medicine at the University of Copenhagen.

The mutation affected the so-called OCA2 gene, which is involved in the production of melanin, the pigment that gives colour to our hair, eyes and skin.

“A genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a ‘switch,’ which literally ‘turned off’ the ability to produce brown eyes,” Eiberg said.

The genetic switch is located in the gene adjacent to OCA2 and rather than completely turning off the gene, the switch limits its action, which reduces the production of melanin in the iris. In effect, the turned-down switch diluted brown eyes to blue. If the OCA2 gene had been completely shut down, our hair, eyes and skin would be melanin-less, a condition known as albinism.

“It’s exactly what I sort of expected to see from what we know about selection around this area,” said John Hawks of the University of Wisconsin-Madison, referring to the study results regarding the OCA2 gene. Hawks was not involved in the current study.

Baby blues

Eiberg and his team examined DNA from mitochondria, the cell’s energy-making structures, of blue-eyed individuals in countries including Jordan, Denmark and Turkey. This genetic material comes from females, so it can trace maternal lineages.

They specifically looked at sequences of DNA on the OCA2 gene and the genetic mutation associated with turning down melanin production.

Over the course of several generations, segments of ancestral DNA get shuffled so that individuals have varying sequences. Some of these segments, however, that haven’t been reshuffled are called haplotypes.

If a group of individuals shares long haplotypes, that means the sequence arose relatively recently in our human ancestors. The DNA sequence didn’t have enough time to get mixed up.

“What they were able to show is that the people who have blue eyes in Denmark, as far as Jordan, these people all have this same haplotype, they all have exactly the same gene changes that are all linked to this one mutation that makes eyes blue,” Hawks said in a telephone interview.

Melanin switch

The mutation is what regulates the OCA2 switch for melanin production. And depending on the amount of melanin in the iris, a person can end up with eye colours ranging from brown to green.

Brown-eyed individuals have considerable individual variation in the area of their DNA that controls melanin production. But they found that blue-eyed individuals only have a small degree of variation in the amount of melanin in their eyes. 

“Out of 800 persons we have only found one person which didn’t fit — but his eye colour was blue with a single brown spot,” Eiberg told LiveScience, referring to the finding that blue-eyed individuals all had the same sequence of DNA linked with melanin production.

“From this, we can conclude that all blue-eyed individuals are linked to the same ancestor,” Eiberg said. “They have all inherited the same switch at exactly the same spot in their DNA.” Eiberg and his colleagues detailed their study in the online edition of the journal Human Genetics. 

That genetic switch somehow spread throughout Europe and now other parts of the world.

“The question really is, ‘Why did we go from having nobody on Earth with blue eyes 10,000 years ago to having 20 or 40 per cent of Europeans having blue eyes now?” Hawks said. “This gene does something good for people. It makes them have more kids.”

Bone Analysis Offers a Glimpse of 19th-Century Working Mothers

Bone Analysis Offers a Glimpse of 19th-Century Working Mothers

A 19th-century rural Dutch village had unusually low rates of breastfeeding, likely because mothers were busy working, according to a study published April 13, 2022, in the open-access journal PLOS ONE by Andrea L. Waters-Rist of the University of Western Ontario and colleagues.

Artificial feeding of infants, as opposed to breastfeeding, is considered a fairly modern practice, much rarer before the advent of commercially available alternatives to breast milk.

However, studies of past populations in Europe have found that breastfeeding practices can vary significantly with a regional cultural variation. In this study, researchers examine a 19th-century dairy farming rural village in the Netherlands to explore factors linked to lower rates of breastfeeding.

Breastfeeding leaves its mark in the bones of infants in the form of altered ratios of stable carbon and nitrogen isotopes. In this study, researchers tested isotopic signatures in the remains of 277 individuals, including nearly 90 infants and children, from Beemster, North-Holland.

They found little to no evidence of breastfeeding, surprising given that this community exhibit features commonly associated with breastfeeding communities of the time, such as a Protestant population of moderate socioeconomic status, and mothers commonly working in or near the home.

Since other evidence indicates that mothers in 19th century Beemster were commonly working as dairy farmers, the researchers suspect that a high workload and a ready supply of cow’s milk as an alternative infant food source were important factors contributing to these low rates of breastfeeding.

At a few urban archaeological sites, mothers who worked long factory shifts have been found to have low rates of breastfeeding, but a similar phenomenon has not been found in a rural population until now.

Future studies on more sites will help elucidate how regional cultural practices impacted rates of breastfeeding over time, and in turn, how these factors have impacted infant health over recent centuries.

The authors add: “Artificial feeding of infants is not just a recent phenomenon.

Female dairy farmers from 19th century Netherlands chose to not breastfeed, or to wean their infants at a young age, because of the availability of fresh cow’s milk and high demands on female labour.”

Possible 18th-Century Tavern Uncovered in Eastern Virginia

Possible 18th-Century Tavern Uncovered in Eastern Virginia

After three years of searching, archaeologists think they may have found the remnants of an 18th-century tavern.

“We found a substantial rubble deposit of handmade brick and oyster shell mortar with some evidence of burning [that may be chimney soot],” said Fairfield Foundation lead archaeologist Dan Brown. “We think it might be the Quarles Tavern.”

Although not much is known about the tavern other than what is recorded in historical documents, the tavern was owned at one time by a man named John Quarles.

Possible 18th-Century Tavern Uncovered in Eastern Virginia
Volunteers Tom Hawkins, Bonnie Pearsall, Elcke Erb, T’ziyon Levi-Shackleford, Marc Reynolds and Marshall Pearsall work with Fairfield Foundation staff archaeologist Oliver Mueller-Heubach at the site believed to be the location of an 18-century tavern in King William County’s courthouse area.

Now that archaeologists have identified what they think is the tavern, Brown said they will conduct additional tests to “find the edge of the deposit, hoping it will confirm the width of the building’s foundation … and delineate the building’s outline and dimensions” to verify it is the tavern.

The King William Historical Society sponsored the project after Alonso Dill’s map of the historic courthouse area, based on old records, piqued the society’s interest. It soon joined forces with the Fairfield Foundation, an archaeological preservation organization based in Gloucester.

Fairfield Foundation staff archaeologists Oliver Mueller-Heubach and Ned Rose work with volunteers Marc Reynolds, Mike Crombie, Charles Van Fossen and Marshall Pearsall at a site believed to have been the location of an 18th-century tavern in King William County’s courthouse area.

According to Brown, Dill’s map provided approximate locations of several buildings that no longer exist, including Hill’s Hotel (located across Courthouse Road in the green triangle lot), the Quarles Tavern (located east of the short brick wall area) and the brick stables (located in the asphalt overflow parking lot on Horse Landing Road).

Using Dill’s map and Ground Penetrating Radar (GPR) performed by Bob Chartrand, of Chartrand Geoarchaeological Solutions, LLC, in Williamsburg, they were able to search the entire courthouse area. GPR uses subsurface mapping of the earth using radio waves that create a picture.

“It saves us a lot of time and tells us where exactly to dig,” Brown said.

With GPR, Chartrand located many of the buildings’ foundations and even one not on Dill’s map, including a large brick building with a full cellar within the short-bricked wall area of the courthouse, just south of the King William Historical Society Museum, Brown said.

“That area was privately owned up until the early 20th century, and the building was destroyed around the time the county bought the property but, what was the building?” he asked. “We’re still trying to find that out.”

Although his team is at the preliminary stages of understanding what exactly the archaeology says about King William’s society in the 18th century, Brown said that he can confirm that “the tavern hosted a very high-class clientele, [as] seen in the variety of relatively rare and expensive ceramic fragments, personal items and other artefacts found to date.”

Artefacts recovered from the upper layers above the brick rubble include (l-r) an oyster shell, two iron nails (potentially 18th-century wrought nails), a 19th-century white glass button, and an 18th-century slipware rim fragment and an unidentified iron object.

Brown has also deduced that the courthouse area was busy at that time. In fact, busier relative to today. Also, Brown said every part of society, from enslaved Africans and Indigenous people to wealthy individuals and families came to the courthouse area.

Although he has learned a lot about King William County through artefacts, Brown keeps digging up more questions.

This hole shows what archaeologists believe to be the foundation of an 18th-century tavern in King William County’s courthouse area.

“Did Indigenous people live here? When they built the courthouse, what other buildings were built alongside it and when and where? Over the 18th and 19th centuries, what government buildings came and went?”

Brown has a theory as to why business eventually slowed down in the King William courthouse area: urban development.

“There was an increase in state governments, development in West Point and more stores to choose from,” he said. “People had less of a need to go to the courthouse for things.”

Since the project is ongoing, the King William Society and Fairfield Foundation will continue to use GPR and dig around the courthouse area in hopes of finding new buildings and answering more questions.

According to Brown, the group also aims to “preserve the county’s precious cultural resources” by making them available for viewing in the King William Historical Society Museum and “sharing this process with the public.”

“Plans are in the works for us to host all 273 fourth and fifth graders in the county and that is a remarkable honour,” said Brown. “They would get to see the remarkable museum exhibits put together by the museum council, the architectural complexities and mysteries of our courthouse buildings, and get to dig too.”

Brown said he is also looking forward to hosting the public a few days every month to visit and participate in a dig.

Artifacts recovered from the upper layers above brick rubble include (top to bottom) a 19th-century whiteware handle fragment, a mid-18th-century white salt-glazed stoneware plate base fragment and a 19th-century colourless bottle fragment.

‘Rare’ 14th Century gold coin found in a secret drawer in Derbyshire

‘Rare’ 14th Century gold coin found in a secret drawer in Derbyshire

A 14th-century French gold coin was discovered inside one of three hidden drawers in a bureau inherited by a woman who lives in Derbyshire, England.

The mother of three, Amy Clapp, 37, told reporters she had no idea the 650-year-old coin — or the secret drawers — existed after being left a 20th-century bureau by her distant cousin.

Don Collins of Hansons Auctioneers said the 22-carat coin was “very unusual” and he had “never seen one exactly like it” in more than 50 years, according to the BBC.

Edward Rycroft with the coin and the tiny drawer he found it in.

Experts believe the Raymond IV Prince of Orange Franc A Pied, dating back to 1365, could fetch double the guide price of £1,200 to £1,800 when it is auctioned this spring.

The princes of Orange lived in France in the 14th century. The principality originated as a fiefdom in the Holy Roman Empire in the kingdom of Burgundy.

Hansons furniture valuer Edward Rycroft with coin and Amy Clapp.

Clapp said to the Daily Mail, “I can’t even remember meeting my great cousin, but I received a letter from a solicitor before Christmas informing me that I’d been left various items of furniture. Apparently, the will was written when I was 13 years old.”

The bureau’s owner didn’t even find the coin herself. She’d sent the bureau to Derbyshire’s Hansons Auctioneers to sell after examining it, believing that it was empty. But three secret drawers existed in the bureau, and they were found by the furniture auctioneers.

Edward Rycroft, the furniture valuer at Hanson’s, was the one who made the discovery. The gold coin was hidden in a secret drawer. It turned out to be rare, and highly valuable. Rycroft told the Derbyshire Times: “I know bureaus like this often have tiny, secret drawers — sometimes called coin drawers — so I always check them just in case. But in 10 years of valuing furniture, I have never found anything in them  … until now.”

Clapp said she “would never have found that in a million years” and hoped to donate some of the proceeds of the coin sale to a charity.

The wooden bureau itself is estimated at being worth less than $100.

Rycroft said, “I’m delighted for the family. The coin’s worth a small fortune. I knew straight away it was gold and really special. It’s the most amazing thing I have ever found by chance.”

As for Clapp, a family support worker, she said: “I’m delighted. I was working in London when Edward phoned me. As a family, we’ve had some bad luck in the last two years, so for something like this to happen to us is amazing.”

Rycroft suggested everyone be sure to search their furniture carefully. “If you’ve got an old bureau at home do check for secret drawers — you never know, you may be sitting on a windfall too.”

Who Was the Exceptionally Powerfully Built Viking Buried in the Gokstad Ship?

Who Was the Exceptionally Powerfully Built Viking Buried in the Gokstad Ship?

Ever since the publication of a scientific article in 1883, “everyone” has known that the skeleton found in the magnificent Gokstad ship in Eastern Norway belonged to Olaf Geirstad-Alf, the legendary Viking king of the House of Yngling. In recent years, however, research has shown that this must be wrong.

The clinker-built Gokstad ship dating back to the year 890 AD is currently on display at the Viking Ship Museum in Oslo, Norway.

Dendrochronological datings show that the Gokstad ship was built about the year 890 AD, i.e. the height of Norwegian expansion in the British Isles, and in the year 901, it was buried in the so-called “King’s Mound” (Gokstad Mound) in Vestfold, Eastern Norway.

The vessel largely is constructed of oak and is 23.22 meters (76.18 ft) long and 5.18 meters (17 ft) wide. On each side, there are sixteen oar holes, and the ship was built to carry thirty-two oarsmen. With a steersman (the ship’s owner) and lookout, the crew consisted of thirty-four people but could carry a maximum of seventy men with some equipment.

The Gokstad ship was both flexible and fast with a top speed of more than 12 knots (14 mph) propelled by the sail of about 110 square meters (1,200 square feet). Recent tests have shown that the vessel worked very well with both sail and oars, and it may have been used for trade, Viking raids and explorations. There have not been found any thwarts, and the oarsmen probably have been sitting on chests that also contained their personal equipment.

Grave Findings

When the Gokstad ship was excavated, sixty-four shields were discovered (thirty-two on each side) and every second was painted in yellow and black. In the front part of the ship, there were discovered fragments of white wool fabric with sewn red stripes that probably were parts of the sail. Behind the mast, a burial chamber was discovered with the remains of a beautifully woven carpet decorating the walls. Inside the burial chamber, there was found a made bed containing the buried person.

In addition to the Gokstad ship itself, there were among other objects found a gaming board with gaming pieces made of horn, fish hooks, harness fittings of iron, lead and gilded bronze, kitchenware, and six beds, one tent, one sled and three smaller boats. There were also discovered a large number of animal bones that had belonged to twelve horses, eight dogs, two northern goshawks and two peacocks.

Animals in the Gokstad ship grave.

When the excavation took place in 1880, it soon became clear that parts of the grave goods had been plundered in ancient times: there were no jewellery or any precious metals in the grave, nor any weapons that in the Viking Age were an important part of a warrior’s grave goods preparing him for his journey to the Afterlife. Just south of the Gokstad burial mound, a major trading centre has recently been discovered. The items excavated tell different stories and document the close connection between Vestfold and the rest of the world at the time. Weights found in the trading centre show that hectic trading activities took place at about the same time as the Gokstad ship burial.

Human Bones

In 2007, bones from a human skeleton found in the grave were thoroughly examined by Professor Per Holck at the Institute of Basic Medical Sciences, University of Oslo.

The examination proved that the bones had belonged to a man who died in his 40s. He was between 178 (5ft 10 in) and 184 centimetres tall (6ft), something that was significantly taller than the average height of the period (165 cm / 5ft 5in) and the Viking was exceptionally powerfully built. The man in the Gokstad ship grave has mainly eaten terrestrial food [food coming from land and not the sea, like meat and corn] showing that he has belonged to the Norse community’s social elite.

Professor Holck found clear marks of five or six different cuts from an axe, knife and sword: one on each of the thigh bones, two or three on the left and one on the right calf bone. It is likely that the Gokstad man did not survive these injuries, something proved by the fact that there are no signs that his wounds have healed.

Cut on the leg (tuberositas tibiae), probably from a sword.

Although none of the injuries has been fatal (perhaps with the exception of a cut on the inside of the right thigh bone, which may have damaged the femoral artery), it cannot be excluded that this particular Viking has had other cuts that did kill him, for example in the head (only parts of the skull was discovered).

Aiming for the enemy’s legs was a common fighting technique in the Middle Ages. The legs were not covered by chain mails and were vulnerable, a fact documented from many examples in Norse sagas.

Professor Holck concluded that there must have been at least two people, with three different weapons, who have killed the Gokstad man, and that the cuts indicate that he most likely was wearing armour and killed in battle.

Not King Olaf Geirstad-Alf

The theory is that the skeleton from the Gokstad mound has belonged to Olaf Geirstad-Alf (Old Norse: Ólaf Geirstaða Álfr, the elf of Geirstad) was already described in a scientific article by anatomy professor Jacob Heiberg back in 1883, and the man’s identity has since been widely accepted. In the first section of the Heimskringla King’s Sagas written down in 1225 by Snorri Sturloson, Olaf  «Geirstad-Alf» Gudrødsson is mentioned with a couple of lines: Olaf was a petty king in Vestfold, and the half brother of Halfdan the Black (c. 810 – c. 869 AD). Olaf was allegedly Halfdan’s nineteen years older brother, and thus probably born around the year 800. Since the ship’s grave can be dated back to the year 901, about half a century after Olaf Geirstad-Alf’s death, researchers can safely say that this is not Olaf’s grave.

However, who was the exceptionally powerfully built Viking found in the Oseberg grave chamber?

If we take a close look at the large and versatile Oseberg ship and the rich discoveries, and how the person in the grave was killed – it is quite certain that this was a powerful and respected Viking warrior from Vestfold. The peacocks discovered show that this was a man with an international network and that he did belong to the Norse upper class. Perhaps the birds were a gift from an English king or trophies he brought back home from a Viking raid in Spain?

In Medieval Europe peacocks, a bird species originally brought back from Asia, were considered a symbol of power among kings and aristocrats. Maybe the Gokstad man was a powerful Viking petty king, earl or chieftain who had accumulated enormous wealth abroad?

However, he may also have been an elite warrior, a berserker, one of the king’s loyal elite soldiers who received the funeral he deserved when he was killed in battle. If he was killed in Dublin, London, York– or in Novgorod (Russia), and was brought home to be buried, we do not know. Either way – it is certain that the human bones buried in the Gokstad ship did not belong to King Olaf Geirstad-Alf.

East Bay’s mysterious rock walls: Paranormal? American Stonehenge? Theories abound

East Bay’s mysterious rock walls: Paranormal? American Stonehenge? Theories abound

If walls could speak, what a tale these mysterious huge boulders would tell. Perched high atop the lonely, windswept ridges of the Diablo Range, chains of stacked stones stand sentry above East Bay cities — yet they delineate nothing.

Long the subject of intrigue — Who built them? Why? How? — the walls are now being mapped by a San Francisco State archaeologist who believes they hold important clues to early California history and deserve our attention and protection.

“They are historic sites,” said Jeffrey Fentress, who is measuring and mapping them for the East Bay Regional Park District, then submitting his findings to the California Office of Historic Preservation. “By recording the walls, they become a permanent part of the state archive and are protected — as well as they can be — from future development.”

There are no written or photographic records of their construction in a landscape that has been inhabited by humans for at least 7,000 years. So, like the fabled crop circles of England, the walls have inspired theories ranging from the paranormal to the historically bizarre.

“There is no definitive answer on its origins, which further delights the public, who can take it to new levels of speculation,” said Mark Hylkema, archaeologist for the Santa Cruz District of California State Parks.

New Age mystics have declared that their builders were creatures from a vanished Pacific island; amateur historians suggest that they were Mongols or West Africans. Some theorize that the walls offered defence from intruders; others believe they played a peaceful and spiritual or astronomical role, perhaps serving as a “solstice site” like Stonehenge.

Sections of walls are scattered atop Santa Clara County’s Ed Levin County Park, the Russian Ridge in the Santa Cruz Mountains, several parks within the East Bay Regional Park District and a few private ranches in the Livermore Valley. Some also can be seen in the Sierra foothills, along state Highway 50 past El Dorado Hills.

While well known to the region’s hikers, park officials are reluctant to disclose precise locations because they fear they will attract vandals. A large stone circle on Pleasanton Ridge was destroyed by real estate development in the 1990s.

Standing 3- to 4-feet high and wide, they’re sturdy yet unsecured by mortar. They seem too low to offer much protection, or confine horses. Some rocks are melon-size. The larger ones weigh up to a ton. Lifting them no doubt required the effort of several men.

“Some go in a straight line, others twist like a demented snake up a steep hillside, others come in a spiral two hundred feet wide and circle into a boulder,” amateur wall historian Russell Swanson wrote in 1997. Over 12 years, he visited more than 40 miles of the stone structures. The walls seem out of place in California’s wild golden hills, evoking instead memories of tidy New England fields memorialized by poet Robert Frost, or the rich green pastures of Ireland.

One of many old stone walls found around the southern and eastern San Francisco Bay in California.

Why, in such a vast landscape, didn’t builders simply use barbed wire? Or wood? Instead, they’re built of coarse-grained sandstone, abundant in these hills, called graywacke.

Native Americans say they historically had little interest in erecting boundaries. “In general, our ancestors did not believe in scarring or altering Mother Earth,” said Valentin Lopez, chairman of the Amah Mutsun Tribal Band. In 1904, John Fryer, a UC Berkeley professor of Oriental languages and literature, asserted that they were “undoubtedly the work of Mongolians. … The Chinese would naturally wall themselves in.”

Several years later, ethnologist Henry C. Meyers agreed they were the product of strong and ancient civilizations: “Neither man nor men of the present day could possibly put large stones of these walls in place without appliances of some kind.”

Dr. Robert F. Fisher, the founder of the Mission Peak Heritage Foundation, told the Santa Cruz Sentinel in 1984 that he was mystified: “They predate the Indians. They predate the Spaniards. It doesn’t fit in with any of the later histories.”

More recently, lichen analyses date the walls back to the 1850s to 1880s — the post-Gold Rush era, when California was swelling with newcomers anxious to lay their claim on acreage. While imperfect, the technique dates inanimate objects by measuring the diameter of growing lichens.

That evidence hasn’t stopped the internet from spawning its own theories, crediting mythical Lemurians — tall people who breathed through scaly aqua skin and sought refuge in California after the disappearance of the Pacific continent of Mu. Much more likely is an explanation put forth by a consensus of experts like Fentress; State Parks archaeologist Hylkema; and Beverly Ortiz, cultural services coordinator of the East Bay Regional Park District.

The walls were likely built to contain cattle by new European immigrants in the post-Gold Rush era, perhaps using unpaid or low-paid Native American, Chinese or Mexican labour, they believe. The stones stand as a legacy of our once-rural culture, poignant reminders of people long gone. Unlike the railroad or mining tycoons — the Crockers, Stanfords, Huntingtons and Floods — these early ranchers left no mansions, antiques or jewellery. Only rocks.

“The rock walls throughout the East Bay are neither ancient nor mysterious, even if the specific individuals who made them are unknown to us today,” Ortiz said. “They are associated with historic Euro-American ranching, dairy and dry farming activities.”

The historians note that cattle and sheep don’t need tall walls to be managed; they’re docile and don’t jump. The rocks, Fentress and Ortiz said, also could have been used to help catch or drain water or establish boundaries between ranches.

But which ethnic group built the walls?

The Portuguese were among the early ranchers, said Robert Burrill and Joseph Ehardt, of the Milpitas Historical Society. But other immigrants, such as Italians, Irish and Spaniards, may have brought wall-building skills from their homelands.

These post-Gold Rush settlers, who were not wealthy, likely built walls with their own hands, Fentress said. But they also may have enlisted low-cost labour from other ethnic groups, such as Mexicans — who had been displaced from their ranchos — and Chinese, who build the railroads and projects like Oakland’s Lake Chabot dam. Or perhaps they were built by Native Americans during an era that authorized the forced apprenticeship of native peoples, a practice not banned until the 1860s.

Archaeologists say the walls are a ghostly elegy of their builders.

“They are essentially the archaeology of the working class, the common people who came here and made a living,” Fentress said. “It is the only evidence we have of these people’s lives — and it is important to tell that story as well as we can.”

Meet The Inca Ice Maiden, Perhaps The Best-Preserved Mummy In Human History

Meet The Inca Ice Maiden, Perhaps The Best-Preserved Mummy In Human History

The must-see attraction for visitors to Museo Santuarios Andinos (Museum of Andean Sanctuaries) in Arequipa, Peru is without a doubt the Mummy Juanita, one of the world’s best-preserved corpses.

Her full head of dark hair is still intact and the skin on her hands and arms, discolouration aside, shows almost no decay. The mummy’s discoverer, Johan Reinhard, even made note of just how perfectly the mummy’s skin had been preserved, “down to visible hairs.”

As peaceful as she looks — a far cry from some of the more ghastly mummies that researchers have discovered — Juanita’s life was a short one that ended with her being sacrificed to the Inca gods.

Meet The Inca Ice Maiden, Perhaps The Best-Preserved Mummy In Human History
Mummy Juanita is on display at the Museum of the Nation in Lima, Peru. March 1999.

Scientists estimate that Juanita was between 12 and 15 years old when she died as part of capacocha, a sacrificial rite among the Inca that involved the deaths of children.

Translated as “royal obligation,” capacocha was the Inca’s attempt at ensuring that the best and healthiest among them were sacrificed to appease the gods, often as a way to stop a natural disaster or ensure a healthy harvest. Considering that Juanita’s body was discovered atop Ampato, a volcano in the Andes, her sacrifice very likely played into the Inca’s mountain worship.

Preparation For Death

Juanita’s life prior to her selection for human sacrifice probably wasn’t all that unusual. Her days leading up to her death, however, were very different from the lifestyle of a typical Inca girl. Scientists were able to use DNA from Juanita’s well-preserved hair to create a timeline of those days and deduce what her diet was like before capacocha.

Markers in her hair indicate that she was selected for sacrifice about a year before her actual death and switched from a standard Inca diet of potatoes and vegetables to the more elite foods of animal protein and maze, along with large quantities of coca and alcohol.

As Andrew Wilson, a forensic and archaeological expert, explained to National Geographic, the final six to eight weeks of life of Inca child sacrifices were one of a very intoxicated psychological state altered by the chemical reaction of coca and chicha alcohol.

Thus archaeologists believe that upon Juanita’s death, she was likely in a very docile and relaxed state. While the Incas would eventually perfect this drug mixture — which, coupled with the mountainous high altitudes, would cause the child sacrifices to fall into a permanent sleep — Juanita wasn’t so lucky.

Momia Juanita

Radiologist Elliot Fishman would discover that Juanita’s death was brought about by a massive haemorrhage from a club blow to the head. Fishman concluded that her injuries were “typical of someone who has been hit by a baseball bat.” After the death blow, her skull swelled with blood, pushing her brain to the side. Had blunt trauma to the head not occurred, her brain would have dried symmetrically in the centre of her skull.

Juanita’s Discovery

After her death, sometime between 1450 and 1480, Juanita would sit alone in the mountains until she was uncovered in September 1995 by anthropologist Johan Reinhard and his Peruvian climbing partner, Miguel Zárate.

If it weren’t for volcanic activity, it’s possible that the mummified young girl would have continued to sit on the frozen mountain top for centuries to come. But because of the volcanic activity warming the snow though, Mt. Ampato’s snowcap began to melt, pushing the wrapped mummy and her burial site down the mountain.

Reinhard and Zárate discovered the small bundled mummy inside a crater on the mountain, along with numerous burial items including pottery, shells, and small figurines.

The thin, cold air 20,000-feet up near the summit of Mt. Ampato had left the mummy incredibly intact. “The doctors have been shaking their heads and saying [the mummies] sure don’t look 500 years old [but] could have died a few weeks ago,” Reinhard recalled in a 1999 interview.

The discovery of such a well-preserved mummy instantly created a surge of interest throughout the scientific community. Reinhard would return to the mountain top a month later with a full team and find two more mummified children, this time a boy and a girl.

Reports from a Spanish soldier who witnessed sacrifices of children in pairs suggest that the boy and girl might have been buried as “companion sacrifices” for Mummy Juanita.

All in all, experts estimate that there may be hundreds of Inca children mummified in the mountain peaks of the Andes still waiting to be discovered.

Treasure of 1,290 Ancient Roman Coins Discovered by Amateur Archaeologist in Switzerland

Treasure of 1,290 Ancient Roman Coins Discovered by Amateur Archaeologist in Switzerland

An amateur archaeologist has found a big treasure trove of over 1,290 priceless, ancient Roman coins dating back to the 4th Century AD near Bubendorf, a municipality in the district of Liestal, in the canton of Basle-County, in Switzerland.

Treasure of 1,290 Ancient Roman Coins Discovered by Amateur Archaeologist in Switzerland

The hoard was discovered by volunteer archaeological scout Daniel Lüdin in a forested area near Wildenstein Castle in September 2021.

The finder, Daniel Lüdin, was searching a forest with a metal detector near Bubendorf, a municipality in the district of Liestal, in the canton of Basle-County, in Switzerland, when he made the discovery.

When his metal detector signalled a strong alert, Lüdin dug down a little and found a few Roman coins and some potsherds, not enough to explain the strength of the signal. He dug down a little more and hit the jackpot.

The coins which were made during the reign of Constantine the Great (AD 306-337) show portraits of the emperor and his relatives in the front.

Daniel Lüdin was very careful. He reconsidered the find, filled in the hole, and informed Archeologie Baselland.

Thanks to this professional approach, they removed the pot in a soil block so that all of the coins, pot fragments, and any invisible archaeological treasures like traces of organic remains could be excavated under laboratory conditions.

The block removal also allowed researchers to CT scan the soil block to map out the contents.

They revealed that the coins in the pot had been separated in two by a piece of cowhide at the time of their burial, although it is currently unclear why and what purpose this served.

Andreas Fischer, of Archaeologie Baselland said: “One can only speculate about the meaning and purpose of this separation.”

What is clear, however, is that these coins are made of a copper alloy and of silver, and they were all “minted during the reign of Emperor Constantine the Great (306-337 AD). The youngest specimens date from the years 332-335 AD.”

A black space seen in the CT scans between two layers of coins turned out to be a simple piece of leather.

The total value of 1290 coppers was the equivalent of a gold solidus or about two months’ salary for a soldier in the legions.

The expert said that often, there are simple explanations as to why people would bury their valuables, but none of them appears to apply here.

What makes the hoard so unusual is that it was buried during a time of political and economic stability. Coin hoards from the 4th century were typically buried during periods of unrest, but Constantine’s reign was not among them. Hoards from this period are vanishingly rare throughout the Empire.

It seems likely that this one was buried for other reasons. One possibility is a religious offering as the find site was on the border between three known Roman estates, so it could have been a boundary line sacrifice.
