Ancient Advanced Technology: 2,400-Year-Old Yakhchals Kept Ice in the Desert


The Yakhchāl was an ancient Persian “the refrigerator” that stored food and even ice long before electricity was invented

The ancients were smarter than certain individuals think today. They had no rockets and electricity, no undisputed evidence of such techniques has been discovered, but they have developed technology which we generally do not associate with the ancient world.


The yakhchal (meaning ice pit) was a kind of old coolant constructed in the deserts of Persia (now Iran), which was made without electricity, with contemporary coolants, or with most contemporary coolers. It shows humans ‘ capacity of humans to find solutions to problems with any materials or technology they have available.

Take the Incas, for example, who did not have a developed alphabetic system for writing but had the quipu, a counting device of knots and strings that enabled them to keep track of population records and livestock and even recaptured essential episodes of their folklore.

When it comes to engineering, architectural wonders are omnipresent on almost every continent, whether that be the pyramids of Egypt, Angkor Wat of the Khmer Empire, or even entire underground cities such as Derinkuyu in Turkey’s Cappadocia region.

One great example of smart and sustainable engineering brings us to the Middle East, a realm noted for being one of the cradles of civilization and developing human cultures. There, around the 4th century B.C., the ancient Persians came up with what is known as yakhchāl.

Characteristic ice-house construction called a Yakhchal in Kashan, Iran.

The yakhchāl did not serve as a burial ground or a place to accommodate people, but it instead fulfilled another important function amid the scorching summers.


With excessive heat and arid climate, the region had occupants, the ancient Persians, who needed some way to cool off and store food during the summer months, and that’s when yakhchāls were found of great help.

The word stands for “ice pit.” These edifices provided both space and conditions to store not only ice but also many types of food that would otherwise quickly spoil at hot temperatures.

On the outside, a yakhchāl structure can dominate the skyline with its domed shape, and on the inside, it would typically integrate an evaporation cooler system that allowed the ice and food resources to stay cool or even frozen while stored in the structure’s underground rooms.

It may sound a bit far-fetched that the ancient Persians saved ice in the middle of the desert, but their technique was, in essence, not so complicated.

Yakhchal in Yazd, Iran

A typical yakhchāl edifice would rise some 60 feet, and on the inside, it would contain vast spaces for storage. The leading examples point to figures such as 6,500 cubic yards in volume.

The evaporative cooling system inside the structures functioned through windcatchers and water brought from nearby springs via qanāts, common underground channel systems in the region designed to carry water through communities and different facilities.

The evaporative cooling allowed temperatures inside the yakhchāl to decrease with ease, giving a chill feeling that indeed you are standing inside one big refrigerator.


The walls of it were constructed intelligently as well, with the usage of special mortar that provided super insulation and protection from the hot desert sun. It was a mix of sand, clay, and other components such as egg whites and goat hair among others.

The structures also contained trenches at the bottom, designed to collect any water coming from molten ice. Once collected, this water was then refrozen during nighttime, making maximum use of the resource as well as the cold desert night temperatures. It was a repetitive process.


Not only did the yakhchāls provide basic food resources, treats, and ice for the royals and high state officials, but the service was so attainable that even the poorest of society could access it. 

Usage of yakhchāls has halted in modern times, and though some structures have been damaged and eroded by desert storms, still, many can be found intact across Iran and some of its neighboring countries, as far as to Tajikistan.

The usage of the term yakhchāl lingers on in the region today, commonly referring to refrigerators found in modern-day kitchens.

The “Oldest Gold Of Mankind” was found in the Varna Necropolis


The “Oldest Gold Of Mankind” was found in the Varna Necropolis, on The Bulgarian Black Sea Coast

In 1972, an excavator operator working in the industrial zone of the city Varna will stumble upon something that will turn out to be a very significant historical site. The Varna Necropolis has discovered approximately half a kilometer from Lake Varna and 4 km from the city center. It is estimated that it was made sometime between 4,600 BC to 4,200 BC.


Around 300 graves have been found at this burial site, but the most significant is grave 43. It contained the remains of a high-status person and it was covered with treasures. This single grave contained more gold than all of the other archeological sites from that period put together.

We constantly speak about early, ancient, civilizations like the ones that thrived in Mesopotamia, Egypt, and the Indus Valley, that shaped humanity as we know today. But not a lot of people know about the mysterious people that lived on the shores of the Back Sea in modern-day Bulgaria 7,000 years ago. Archeologists call this civilization the Varna Culture.

The Varna Culture was considered small and insignificant for a long time until it was proven that this was a highly developed culture that preexisted Mesopotamian and Egyptian civilizations. The discoveries made in the Varna Necropolis also showed that it was that first known culture that produced artifacts made of gold. This site is the largest prehistoric necropolis in south-eastern Europe.

 

According to the evidence, gold processing in the Varna region started between 4600 and 4200 BC. The ore processing technology was constantly developing here, and soon, the craftsmen became very skilled in manufacturing copper and gold items. They had the perfect products for trade.

Varna people were perfectly situated between the east and the western world. One one side they had the Black Sea and the opportunity to trade with their neighbors that lived around it and beyond, and on the other side, the road was opened for trade with the whole Mediterranean region. Because of this Varna became an important trading center.


They were able to accumulate great wealth (especially the craftsmen that worked with gold and copper) and develop a nice society mostly consisted of Metallurgists, merchants, and farmers, kind of a class system. This was the basis upon which a powerful and influential culture emerged, one that would spread across Europe for thousands of years.

Before 1972, the only artifacts found from the time of the Varna Culture were tools, vessels, utensils, and figurines made from stone, flint, bone, and claystone made. But, after archeologists Mihail Lazarov and Ivan Ivanov revealed the Varna Necropolis to the world, this amazing civilization was viewed from a different perspective.

These are probably the oldest gold artifacts in the world.


Inside the 300 graves of the necropolis, archeologists unearthed more than 22,000 unique artifacts. This huge list of items contains more than 3,000 golden artifacts, that is 6 kilograms of pure gold. Besides this, there were also plenty of high-quality copper, flint and stone tools, jewelry, shells of Mediterranean mollusks, pottery, obsidian blades, and beads.

The Varna man 

Among the many elite burials in the necropolis, there was one that was different from the others. Different in the sense of “more spectacular.” After uncovering grave 43, archeologists concluded that it was the final resting place of a high-status male, probably a ruler, or some kind of leader in the society.

This was the richest grave of all that have been found, not only in Varna Necropolis but in the whole world at that time. The person was buried with a beautiful golden scepter in his hand. The scepter is a symbol of high rank or spiritual power.

His whole body and its surroundings were covered with golden items. Necklaces, bracelets, earrings, round shaped golden items placed on specific parts of the body, and he even had a golden plate around the genitals. Together with the golden artifacts, the weapons that probably belonged to this person were also placed around his body.

Besides the material richness that Varna necropolis provided archeologists with, it also gave an insight into the hierarchy in this ancient society, their religious beliefs and intricate burial practices. Males and females were buried differently. Males were laid out on their backs while females were placed in the fetal position. There was also another type of graves found.


Some of the graves didn’t contain skeletons, they were only filled with items. These symbolic graves, known as cenotaphs, were one of the richest with gold and treasures. They contained masks made of clay and gold amulets made in the shape of women, placed below the mask, where the neck of a buried person was supposed to be.

Some of the items found inside the “symbolic graves”

The amulets are symbolizing pregnancy and fertility which indicates that they are meant for women. The empty graves also contained a copper pin, a flint knife, and a spindle whorl.


This further indicates that the symbolic graves were made for women, or as a gift for some kind of deity that symbolizes the feminine principle. It is still a mystery why these graves were left without human remains.

The Varna civilization is without direct descendants, they were probably assimilated in other surrounding European and Asian cultures during all those centuries of turmoil in this region.

However, they left a huge legacy and with their accomplishments they made the appearance of the following European civilizations possible. We may never know how the Varna people really lived, but Varna necropolis with all the magical artifacts opens our imaginations.

Severed head of large wolf found perfectly preserved in Siberian permafrost 40,000 years after it died


The severed head of large wolf found perfectly preserved in Siberian permafrost 40,000 years after it died

The severed head of large wolf found perfectly preserved in Siberian permafrost 40,000 years after it died
Scientists estimate that the wolf lived 40,000 years ago.

The sensational find is believed to be the world’s first full-sized Pleistocene wolf, and due to the high quality of preservation, provides new insight into the extinct species.


You never know what you might encounter during a casual stroll in Siberia. Local resident, Pavel Efimov, was walking along the Tirekhtyakh River in the Russian Republic of Sakha when he came across something bizarre: a severed wolf head.

But upon closer examination by experts, they found that it wasn’t just the head of any kind of wolf, but that of a prehistoric predator which lived 40,000 years ago during the Ice Age.

“This is a unique discovery of the first-ever remains of a fully grown Pleistocene wolf with its tissue preserved,” paleontologist Albert Protopopov from the Republic of Sakha Academy of Sciences told The Siberian Times.

 

The head, which measures 16 inches in length and is larger than half the body length of a modern-day wolf, is astonishingly well-preserved with its fangs, thick fur, soft tissue, and brain intact.

Although this is not the first such discovery of an ancient wolf in the Siberian territory, other discoveries have typically been skull specimens or the remains of pups. This head is believed to be from an adult wolf aged between two to four years old when it died.


The incredible discovery was announced in a joint exhibition organized by Yakutian and Japanese scientists in Tokyo, Japan. Further analysis of the wolf’s DNA will be done by an international team of scientists at the Swedish Museum of Natural History.

By examining the wolf’s ancient DNA, researchers hope to learn more about the evolution of ancient wolves to their modern iterations.


The researchers have time-stamped the impressive specimen to 40,000 years ago during the Pleistocene era.

Analyzing the specimen’s ancient DNA will allow scientists to learn more about the evolution of modern wolves.

In addition to some genetic analysis, the ancient wolf’s features will be reconstructed using a non-invasive x-ray with which the inside of the skull can be examined without destroying the head.

The Siberian permafrost, which includes areas in northern Canada, Alaska, and Greenland, has been host to other incredible archaeological finds in the past.

In fact, the team responsible for the recovery of this wolf head struck big in 2015 and 2017 with the discovery of several ancient cave lion cubs.

In 2017, one ancient cave lion cub was discovered around the same place by the Tirekhtyakh River in the Siberian permafrost territory.


Before then, researchers had already uncovered two other cubs — which scientists named Uyan and Dina — in 2015. The two cubs were unearthed on the banks of a different river still in the permafrost region.

“Everyone was amazed then and did not believe that such a thing is possible, and now, two years later, another cave lion has been found in the Abyiski district,” Protopopov said then.


Researchers dated all three cub specimens between 20,000 to 50,000 years ago, around the same time the ancient cave lion population became extinct.

Like the wolf’s head, the lion cubs were incredibly well-preserved. The Cubs had all their limbs intact and showed no external injuries. The prehistoric animals were so perfect that they sparked a sudden interest among some scientists to clone the little beasts.

Just this past year, a 40,000-year-old extinct horse and 50,000-year-old wolf pup were also uncovered in the permafrost.

The ancient cave lion cubs were placed side-by-side with the new wolf specimen during the recent announcement by the researchers. The ancient wolf head has yet to ignite the same cloning discussion, but that doesn’t mean that it won’t in the future.

World’s Biggest Mass Child Sacrifice Discovered In Peru, with 140 Killed in ‘Heart Removal’ Ritual


World’s Biggest Mass Child Sacrifice Discovered In Peru, with 140 Killed in ‘Heart Removal’ Ritual

Skeletons at the sacrifice site showed evidence to suggest their chests had been cut open and their hearts removed.
Skeletons at the sacrifice site showed evidence to suggest their chests had been cut open and their hearts removed.

The largest child sacrifice on record took place after a torrential rainfall, when about 140 children and 200 young llamas likely had their hearts ripped out by the ancient Chimú culture in A.D. 1450, in what is now Peru.


The reason for the sacrifice, however, remains a mystery, according to a new study. Even so, the scientists of the study have several ideas. For instance, heavy rainfall and flooding from that year’s El Niño weather pattern may have prompted Chimú leaders to order the sacrifice, but without more evidence, we’ll likely never know the real reason, said study co-researcher John Verano, a professor in the Department of Anthropology at Tulane University in New Orleans.

Study lead researcher Gabriel Prieto, an assistant professor in archaeology at the National University of Trujillo, Peru, learned about the sacrificial site in 2011 after a father approached him while he was doing fieldwork on another project.

The father described a nearby dune with bones poking out of it. The father said, “Look, my kids are bringing bones back every day, and I’m tired of it,” said Verano, who later joined the project in 2014. Once at the dune, Prieto immediately realized that the site had archaeological significance, and he and his colleagues have been working on it since, excavating and studying the human and llama (Lama glama) remains at the site, known as Huanchaquito-Las Llamas.

 

“It’s the largest child sacrifice event in the archaeological record anywhere in the world,” Verano said. “And it’s the largest sacrifice with llamas in South America. There’s nothing like this anywhere else.

“Who were the victims?

The site holds the remains of at least 137 boys and girls and 200 llamas. Many of the children and the llamas had cut marks on their sterna, or breastbones, as well as displaced ribs, suggesting that their chests had been cut open, perhaps to extract the heart, the researchers wrote in the study.


The children ranged in age from 5 to 14 and were generally in good health, according to an analysis of their bones and teeth. These youngsters were wrapped in cotton shrouds and buried either on their backs with extended legs, on their backs with flexed legs or and resting on one side with flexed legs.

Many were buried in groups of three and placed from youngest to oldest. Some had red cinnabar paint (a natural form of mercury) on their faces, and others, especially the older children, wore cotton headdresses.


The llamas were either laid next to or on top of the children’s bodies. In many cases, llamas of different colors (brown and beige) were buried together, but facing different directions. Also buried at the site, near the children’s remains, were the bodies of two women and a man.

These adults do not have cut marks on their sterna, suggesting their hearts weren’t removed. Rather, one woman likely died from a blow to the back of the head and another suffered from blunt force trauma to her face. The man had rib fractures, but it wasn’t clear whether these injuries happened before or after death, possibly due to the weight of the rocks that were placed over his body, the researchers said.

The children weren’t buried with any discernible offerings, but the researchers did find a pair of ceramic jars and wooden paddles on the edge of the site, next to a single llama.

What happened?

The Chimú culture dominated a large part of the Peruvian coast from the 11th to 15th century. It thrived, in part, because of its intensive agriculture; the Chimú watered their crops and livestock with a sophisticated web of hydraulic canals, the researchers wrote in the study.

This area is typically dry, drizzling only a few times a year. But it’s possible an extreme El Niño event, when warm water evaporates from the southern Pacific and falls as torrential rain on Peru’s coast, caused havoc in the society, not only flooding the Chimú’s lands but also driving away or killing marine life off the coast, Verano said.


Evidence shows that when the children and llamas were sacrificed, the area was sodden with water, even capturing human and animal footprints in the muck that still exist today. It’s unclear why this particular site, located almost 1,150 feet (350 meters) from the coast about 2 miles (3.2 kilometers) north of the city of Chan Chan, was chosen for the sacrifice, but researchers have some idea for why the children were chosen.

Children are often seen as innocent beings who aren’t yet full members of society, and thus might be viewed as appropriate gifts or messengers to the gods, Verano said. Moreover, these children were not all locals. Some of the children had experienced head shaping, and an analysis of carbon and nitrogen isotopes (an isotope is a variation of an element) in their remains showed that these kids came from different regions and ethnic groups within the Chimú state, the researchers found.


It’s unclear why their hearts were removed, but “worldwide, everyone is aware that the heart is a very dynamic organ,” Verano said. “You can feel and hear it beating. It’s very vital. If you take the heart out, a lot of blood comes out and the person dies.”Today, some people in the Peruvian highlands and Bolivia still remove the hearts from sacrificed llamas, Verano noted.

Sometimes the removed heart is burned and the animal’s blood gets splashed on places like mines, a measure thought to protect the workers within. However, it’s unknown how the Chimú viewed and treated hearts in antiquity, Verano said. The children’s remains are now safely stored by Peru’s Ministry of Culture, and the researchers have submitted permits so they can continue to study them, Verano said.

The discovery shows “the importance of preserving cultural patrimony and archaeological material,” Verano said. “If we had had not dug this, it would probably be destroyed now by a housing and urban expansion. So we’ve saved a little chapter of prehistory.”The study is “an incredible insight into the ritual and sacrificial practices of the Chimú kingdom,” said Ryan Williams, a curator, professor and head of anthropology at The Field Museum in Chicago, who has worked as a South American archaeologist for more than 25 years.

He added that while human sacrifice is reviled in our modern society, “we have to remember that the Chimú had a very different world view than Westerners today. They also had very different concepts about death and the role each person plays in the cosmos,” Williams, who was not involved with the study. Given that the sacrifice may have been in response to devastating floods, “perhaps the victims went willingly as messengers to their gods, or perhaps Chimú society believed this was the only way to save more people from destruction,” Williams said.

Face Of Norwegian Boy Who Lived 8,000 Years Ago Reconstructed


Face Of Norwegian Boy Who Lived 8,000 Years Ago Reconstructed

Using DNA analysis and modern forensic techniques, scientists have reconstructed the face of a Stone Age boy who lived in Norway. The Vistegutten – the boy from Viste died at only 14 years old. Why he passed away so early is unknown because it seems he was healthy.

You can now see the full reconstructed figure of Vistegutten at a new permanent exhibition in Jæren. Oscar Nilsson has equipped him with a fishing spear and a fishing hook.


“The young boy was buried in the small Vistehola, a cave located a little north of Stavanger in southwestern Norway. The same little cave that his parents may have lived in.

He is the best-preserved person from the Stone Age in Norway,” Science in Norway reports.

“I spend most of my day working with skeletons of ancient people,” archaeologist Sean Denham at the Museum of Archaeology in Stavanger says.

 

“But seeing a living person in front of me in this way is something completely different. Oscar Nilsson has done a fantastic job with this new reconstruction.”

“Denham is also happy about the increased interest in the Stone Age in Rogaland and Norway that the museum, in collaboration with sculptor and archaeologist Nilsson, has now managed to achieve with this reconstruction.


Fish and nuts

During an archaeological excavation of Vistehola in 1907, researchers found the boy’s remains.

He was only 125 centimeters tall.

Vistehola is located 10 kilometers northwest of Stavanger city center. This is one of the most famous settlements from the Stone Age in Norway. Here, the skeleton of Vistegutten was found during an archaeological excavation in 1907. New methods have made it possible to extract DNA from the skeleton.


With the help of new research methods, the researchers know that the boy has eaten as much food from the sea as from land. Cod, seal, and wild boar were on the menu for those who lived near the beach at Jæren. So were shellfish and nuts.

Even for a Stone Age man, Vistegutten was small in stature. Adult men from the Stone Age in Norway were probably 165-170 centimeters tall. The women may have been 145-155 centimeters tall.

Both sexes had strong physiques, the signs of which can be seen in Vistegutten as well. Eyes and cheekbones were often quite prominent in people in Norway at the time.

The boy was probably fairly dark-skinned.

Face shape, skin and hair

“For a while, there was some doubt about whether this was a girl or a boy. But with the help of DNA analysis, we can now say with certainty that Vistegutten was a boy,” Denham says.


The reconstruction Oscar Nilsson has made is based on DNA analysis. It also builds on a project from 2011, where researchers at the University of Dundee in Scotland scanned the skull of Vistegutten with a laser, and created a 3D model of his head.

Life at Jæren was probably good when Vistegutten lived there. The landscape was covered in deciduous forests with wild boars, moose, and deer. The boy has also eaten a lot of food from the sea. The climate was milder than today and attracted people from the south to Norway. Examinations of the skeleton tell us that Vistegutten did not have any serious illnesses. He hasn’t starved either. When he died, he was buried under the family’s ‘living room floor’ inside the small cave. It must mean that they wanted to have the little boy close to them after he was dead.

“The DNA analysis that was carried out later, tells us more about the shape of his head,” Denham says. “We are a little more uncertain about his skin color, hair color, and the color of his eyes. So here we rely on the other finds we have of Stone Age people in Norway.”


The average lifespan in the Old Stone Age was not very high. This was largely due to the fact that so many young children died. When people first reached adulthood, living to be over 50 years old was not unusual.

We don’t know why Vistegutten died so young.

Archaeologists Find Massive Underground World Belonging To A Long Lost Civilization In Peru


Archaeologists Find Massive Underground World Belonging To A Long Lost Civilization In Peru

Researchers in Peru have discovered a complex underground world belonging to the ancient Chavín culture that has been identified as burial chambers that date back thousands of years.


The culture developed in the northern Andean highlands of Peru between 1,300 and 550 BC. The Chavín extended its influence to other civilizations along the coast.

The Ancient Chavin civilization developed advanced knowledge not only in metallurgy, but in soldering, and temperature control. The ancient Chavin used early techniques to develop refined gold work.

Not, researchers have discovered galleries, ceramics and even a place where this civilization carried out burials, located beneath the surface. They say it’s the most important archaeological discovery made in the last 50 years.

 

Archaeologists Find Massive Underground World Belonging To A Long Lost Civilization In Peru
Seen in this image are the new underground galleries that have been found containing the first human burials of the Chavin period.

Since June of 2018, a team of archaeologists has unearthed three new galleries in an area adjacent to the circular plaza of Chavín. In the place, they have found remarkable pieces of ceramics, utensils and intact human burials.

According to an American anthropologist and archaeologist John Rick, in charge of the Archaeological and Conservation Research Program of Chavín, the three discovered galleries come from the late period of this civilization that developed between 1,300 and 550 BC.


“What these galleries show is that Chavín has a much larger underground world than we think,” said Rick.

The Ministry of Culture estimates that to date only 15% of the area has been explored.

Inside one of these underground galleries, archaeologists discovered artefacts that belonged to the later Huaraz culture.


These successive occupations, found at different levels in the archaeological complex demonstrate the cultural and religious importance that Chavin had in the central highlands for centuries.

The project’s specialists used small robots with built-in micro-cameras to carry out the explorations. These machines – designed on-site by engineers from Stanford University – entered very small areas and discovered cavities in the Chavin labyrinths, where pottery was preserved.

Chavin de Huantar was designated a UNESCO World Heritage Site in 1985. So far 35 interconnected underground passageways have been found at the site, Peru’s culture ministry said.

How white skin evolved in Europeans: Pale complexions only spread in the region 8,000 years ago, study claims


How white skin evolved in Europeans: Pale complexions only spread in the region 8,000 years ago, study claims

Humans around the world display myriad skin tones and eye colors that are fascinating and wonderful in their variety. Research continues on to see how people have acquired the features they have now and when to complete our puzzle of ancient human history.


New anthropology research now suggests that light-colored skin and the tallness associated with European genetics are relatively recent traits to the continent.

An international team of researchers as headed by Harvard University’s Dr. Iain Mathieson put forth a study at the 84th annual meeting of the American Association of Physical Anthropologists recently.

Based on 83 human samples from Holocene Europe as analyzed under the 1000 Genomes Project, it is now found that for the majority of the time that humans have lived in Europe, the people had dark skin, and the genes signifying light skin only appear within the past 8,000 years.

 

This recent and relatively quick process of natural selection suggests to researchers that the traits which spread rapidly were advantageous within that environment, according to the American Association for the Advancement of Science (AAAS).

This dramatic evidence suggests modern Europeans do not appear as their long-ancient ancestors did.


Spreading Genetics

The samples are derived from a wide range of ancient populations, rather than a few individuals, and they supplied researchers with five specific genes associated with skin color and diet.

AAAS reports that the “modern humans who came out of Africa to originally settle Europe about 40,000 years are presumed to have had dark skin, which is advantageous in sunny latitudes.


And the new data confirm that about 8500 years ago, early hunter-gatherers in Spain, Luxembourg, and Hungary also had darker skin: They lacked versions of two genes—SLC24A5 and SLC45A2—that lead to depigmentation and, therefore, pale skin in Europeans today.

Then, the first farmers from the Near East arrived in Europe; they carried both genes for light skin. As they interbred with the indigenous hunter-gatherers, one of their light-skin genes swept through Europe, so that central and southern Europeans also began to have lighter skin. The other gene variant, SLC45A2, was at low levels until about 5800 years ago when it swept up to high frequency.”

This differed from the situation farther north. Ancient remains from southern Sweden 7,700 years ago were found to have the gene variants indicating light skin and blonde hair, and another gene, HERC2/OCA2, which causes blue eyes.

This indicated to researchers that ancient hunter-gatherers of northern Europe were already pale and blue-eyed. This light skin trait would have been advantageous in the regions of less sunlight.

Natural Selection

Mathieson and colleagues do not specify in the study why the genes were favored and spread as quickly as they did, but it is suggested that Vitamin D absorption likely played a role. Ancient hunter-gatherers in Europe also could not digest milk 8,000 years ago. The ability to do so only came about 4,300 years ago.


Paleoanthropologist Nina Jablonski of Pennsylvania State University notes that people in less sunny climates required different skin pigmentations in order to absorb and synthesize Vitamin D. The pale skin was advantageous in the region, as well was the ability to digest milk.

“Natural selection has favored two genetic solutions to that problem—evolving pale skin that absorbs UV more efficiently or favoring lactose tolerance to be able to digest the sugars and vitamin D naturally found in milk,” writes AAAS.


This new research follows related studies on pre-agricultural European genomes and modern humans in Europe before the rise of farming.

Artist’s depiction of Stone Age peoples

DNA taken from the wisdom tooth of a 7,000-year-old human found in Spain in 2006 overturned the popular image of light-skinned European hunter-gatherers. The study revealed that the individual had dark hair and the dark-skinned genes of an African. However, the man had blue eyes, an unexpected find by researchers. The hunter-gatherer is the oldest known individual in Europe to have blue eyes.

Artist’s impression of a blue-eyed hunter gatherer

Previous research published in 2008 found that the earliest mutations in the eye-color genes that led to the evolution of blue eyes probably occurred about 10,000 years ago in individuals living in around the Black Sea.

The surprising aspect of the findings is that while it is fundamental to natural selection that advantageous genetic attributes spread, it is not often a speedy process. The study shows that these genetic pale skin traits swept across Europe speedily, and that phenomenon is of particular interest to researchers.


The preprint study “Eight thousand years of natural selection in Europe” by Mathieson and colleagues has been published in the online journal BioRxiv. These new findings shed light on humanity’s genetic past, giving us a clearer vision of our ancient origins.

The mystery of ‘The Screaming Mummy’ is finally revealed, and it’s chilling


The mystery of ‘The Screaming Mummy’ is finally revealed, and it’s chilling

He’s back. Prince Pentawere, a man who tried (probably successfully) to murder his own father, Pharaoh Ramesses III, and later took his own life after he was put on trial, is now on public display at the Egyptian Museum in Cairo.


Pentawere’s mummy, popularly known as the “screaming mummy,” was not properly mummified. No embalming fluid was used, and his body was allowed to naturally mummify with his mouth agape and his facial muscles strained in order to make it appear as if the mummy were screaming.

Whether he died screaming or whether he was made to look like that after death is unclear.

The “screaming mummy,” likely that of Prince Pentawere, a man who tried (likely successfully) to kill his own father pharaoh Ramesses III, is now on public display at the Egyptian Museum.

Those burying him then wrapped his body in sheepskin, a material the ancient Egyptians considered to be ritually impure.

 

Eventually, someone placed Pentawere’s mummy in a cache of other mummies in a tomb at Deir el-Bahari.

The prince can take solace in the fact that his assassination attempt appears to have been successful. In 2012, a team of scientists studying the mummy of Ramesses III (reign 1184-1155 B.C.) found that Ramesses III died after his throat was slashed, likely in the assassination attempt that Pentawere helped to orchestrate.


The scientists also performed genetic analysis, which confirmed that the “screaming mummy” was a son of Ramesses III. And, based on the mummy’s unusual burial treatment, the researchers confirmed that it is likely Pentawere’s mummy.

To kill a pharaoh

The Judicial Papyrus of Turin, as modern-day scholars call it, is a manuscript that documents the trials that occurred after Pentawere’s apparently successful attempt at killing his father in 1155 B.C.


A group of butlers who remained loyal to Ramesses III — and his successor, Ramesses IV — oversaw the trial of a vast number of people who had allegedly aided Pentawere, condemning them to death or mutilation.

These conspirators included military and civil officials, women in the royal harem (where the murder of Ramesses III may have happened), and a number of men who were in charge of the royal harem.

Prince Pentawere was allegedly assisted by his mother, a woman named Tiye (no relation to King Tutankhamun), who was one of Ramesses III’s wives.

The judicial papyrus says that Prince Pentawere “was brought in because he had been in collusion with Tiye, his mother, when she had plotted the matters with the women of the harem” (translation by A. de Buck).

Pentawere “was placed before the butlers in order to be examined; they found him guilty; they left him where he was; he took his own life,” the papyrus says.


How exactly Pentawere killed himself is a matter of debate among scholars, with poisoning and hanging (or a combination of the two) generally regarded as being the most likely methods.

While the dead Pharaoh Ramesses III was initially buried in a tomb in the Valley of the Kings, his mummy was moved after the robbery of his tomb. Interestingly, his mummy was dumped in the same mummy cache at Deir el-Bahari as Pentawere’s.


The mummies of the murdered father and his killer son rested together until the family of a man named Abd el-Rassul found the cache in the 19th century.

The screaming mummy is only being displayed temporarily. The display of the mummy has received widespread media attention and it is not clear how long it will be displayed.

17th-Century Warship Pulled From Icy Baltic Sea Is Almost Perfectly Preserved


17th-Century Warship Pulled From Icy Baltic Sea Is Almost Perfectly Preserved

In the 1620s, King Gustavus Adolphus of Sweden ordered the construction of a new warship to protect his citizens. The warship was named Vasa and its construction was hurried as the Swedes waged war in those years with the now-historic bi-confederation entity reigned by one monarch–the Polish-Lithuanian Commonwealth.

Vasa’s port bow.


After its creation, with several superlatives, the Vasa warship was described as being the largest and most capable battleship at the disposal of the Swedish navy.

The ship came to symbolize Sweden’s Great Power Period, in which the Nordic country controlled most of the Baltic Sea and forged its status as one of Europe’s most powerful kingdoms.

The ship’s appearance was stunning, measuring 226 feet in length, 164 feet in height, and weighing more than 1,200 tons. With some 64 cannons installed on it, it promised whoever tried to mess with Vasa would face serious consequences. As it turned out, it never came to that.

 

The ship, against everyone’s expectations, proved to be fallible and faced an end that might easily remind people of the story of the RMS Titanic. Vasa did not hit an iceberg but still ignominiously sunk on its very first journey.

It was an embarrassing incident, overseen by crowds of Swedes who had gathered at the port of Stockholm from where the ship set sails towards the open seas for the very first and last time on August 10, 1628.


There were also prominent guests in the onlooking crowd, including royals and ambassadors from other countries. Having not sailed even one nautical mile, the mighty warship suddenly plunged into the water. Accounts point to errors happening during construction.

The vessel was the work of a Dutch shipbuilder. The contract was signed early in the year 1625 and Vasa was one of four vessels agreed on the list with shipbuilder Henrik Hybertsson.


The original arrangement was to have two smaller and two bigger vessels. Hybertsson died shortly after undertaking the project, and the construction effort was taken over by his assistant, Hein Jakobsson.

Construction plans were obviously modified, as Vasa, which was supposed to be one of the two smaller ships, appeared to be fitting the pair of two bigger ships upon completion. The ship came out much heavier than planned. It also carried extra weights such as hundreds of sculptures and at least 100 tons of ballast.

More evidence shows that the Swedes had the warship tested and noticed something was wrong with it, but under the pushy demands of the king, Vasa was prematurely sailed into the open sea and towards its premature doom.

A strong gust of wind was enough to overturn the vessel. When the water began to enter, all it took was a few minutes for it to sink 105 feet below the surface.

The Swedes were quick to dismiss and forget Vasa. This was to be their new favourite war toy and national pride and joy, yet it now lay sunk on the bottom of the ocean on its maiden voyage. It was a scandal that hurt the reputation of the kingdom, as well as having huge economic repercussions. Vasa had costed a fortune.


While an investigation was ushered in immediately after the ship sank, little could be done. The main shipbuilder had already been dead for over a year.

There were efforts to recover Vasa from the seafloor immediately, but the task seemed impossible with the limited technology of the time. By the 1660s, a group of divers was able to retrieve the cannons, using an early model of the diving bell. The shipwreck was eventually left abandoned and forgotten…until the mid-20th-century.


In 1961, a few years after the shipwreck was rediscovered and identified as the lost 17th-century Vasa vessel, Sweden finally managed to recover it. Although Vasa had for centuries remained submerged in the sea, upon its reappearance it seemed positively in pristine condition.

The underwater position where it had sunk was key. The water was dark enough to stop ultraviolet light from protruding and affecting the ship’s wood. The chilly temperature of the Baltic was also soothing, preventing any rapid deterioration processes.

Having sunk close enough to the harbour, there was enough pollution in the water to bleach most parasites that may have wanted to feast on the wood of the wreck.

But some decaying issues began once the ship was taken out of the water.  Vasa underwent restoration at that point and was treated with substances to protect the wood, however, lab research later confirmed that the wood of the ship was struggling with extremely slow, ongoing fibre degradation.

There is no threat of immediate collapse, but this has remained a major occupation for conservationists who are still looking for the best way to stop the risky process.

Should the Vasa museum where the shipwreck is famously displayed in Stockholm allow its prime exhibit to perish for the second time, it would be a huge national loss. The Vasa goes a long way and has a special history with the Swedes as well as being one of the best-preserved historical ships in all of the world.

This 48-Million-Year-Old Fossil Has an Insect Inside a Lizard Inside a Snake


This 48-Million-Year-Old Fossil Has an Insect Inside a Lizard Inside a Snake

Palaeontologists have uncovered a fossil that has preserved an insect inside a lizard inside a snake – a prehistoric battle of the food chain that ended in a volcanic lake some 48 million years ago.


Pulled from an abandoned quarry in southwest Germany called the Messel Pit, the fossil is only the second of its kind ever found, with the remains of three animals sitting snug in one another.

“It’s probably the kind of fossil that I will go the rest of my professional life without ever encountering again, such is the rarity of these things,” palaeontologist Krister Smith from Germany’s Senckenberg Institute told Michael Greshko at National Geographic. “It was pure astonishment.”

Smith and his team suspect that the iguana ate a shiny insect meal, and then two days later was swallowed headfirst by a juvenile snake.

 

It’s unclear how the snake ultimately died, but what we do know is it got too close to the deep volcanic lake that once bubbled in the Messel Pit, and was either poisoned or suffocated by the toxic fumes.

Its corpse likely slid into the lake after death, where the Russian doll of skeletons was preserved perfectly for millions of years.

“To see this kind of trophic scale recorded within the gut of a snake is a very cool thing,” UK palaeontologist Jason Head from the University of Cambridge, who wasn’t involved with the study, told National Geographic.

While the combination of snake-lizard-bug is entirely unique in the fossil record, this isn’t the first time a prehistoric turducken has been discovered.


Back in 2008, Austrian researchers found a 250-million-year-old fossil that had preserved a shark that had eaten some kind of amphibian that had eaten a small fish.

It’s far more fragmentary than the Messel Pit fossil, but it was the first real indication that the food web of the time was far more complex than researchers had thought.

If anywhere is likely to be harbouring more of these types of fossils, it’s the Messel Pit, which in the past has served up the now notorious Darwinius masillae fossil, a fossilised beetle with its turquoise iridescence largely intact, and two turtles caught in the middle of doing, erm, turtle things…

The best-preserved fossils in the world from the Eocene epoch, which ran from around 56 to 34 million years ago, have been found here, and Smith and his team are already planning another trip back.

“This fossil is amazing,” says one of the researchers, Agustín Scanferla. “We were lucky men to study this kind of specimen.”


The find has been published in Palaeobiodiversity and Palaeoenvironments.
