Brochs: The mysterious circular symbols of Scotland

Travel north through Scotland’s deep glens, its mist and mountains and its velvety moorland and you’ll eventually see them: crumbling stone towers rising against the Highland peaks like ancient crag-top castles. These mysterious Iron Age monuments are known as brochs and they exist nowhere else but here. Yet, while these circular dry-walled structures are as symbolic a feature as any in the Scottish Highlands, their purpose remains unknown.

What is known is that around 2,000 years ago, local tribes started harvesting local stone to build massive prehistoric buildings with walls 5m thick and stretching 13m high. To date, anywhere from 100 to 500 broch sites have been identified, with the densest concentration centred in Scotland’s northern Caithness and Sutherland counties, as well as the Northern Isles.

While early archaeologists thought that brochs (whose name derives from the Lowland Scottish word for “fort”) were the citadels of local chieftains, more recent excavations suggest that the structures were more likely used for residential rather than defensive purposes.

The Mayan Calendar Is Strikingly Like the Chinese Zodiac; Could This Be Ancient Cross-Cultural Exchange?

Ancient Mayan and Chinese calendar systems share so many similarities, it is unlikely they developed independently, according to the late David H. Kelley, whose paper on the subject was published posthumously in August 2016.

Kelley was a Harvard-educated archaeologist and epigrapher at the University of Calgary in Canada. He earned fame in the 1960s for major contributions toward deciphering the Mayan script. His article, titled “Asian Components in the Invention of the Mayan Calendar,” was written 30 years ago, but was only recently unearthed and published for the first time in the journal Pre-Columbiana.

In 1980, a major science journal had solicited the article, said Pre-Columbiana’s editor Dr. Stephen Jett. But, Jett said, “the editors rejected it as being overly documented for the journal’s spare format; understandably for so revolutionary an effort, Dave did not wish to weaken the documentation, and he never published the piece elsewhere.” Jett obtained Kelley’s permission to publish it before he died.

The hypothesis Kelley presented is controversial. He said that the calendars indicate contact between Eurasia and Mesoamerica more than 1,000 years ago, contradicting mainstream archaeology’s understanding that such contact occurred for the first time only a few hundred years ago.

Kelley supported the controversial theory of early transoceanic contact in general. It is a theory that has many other academic proponents and that Pre-Columbiana specializes in exploring. The similarities in the calendar systems is only part of a growing body of evidence for early contact.

Archeologists Discover Evidence Of Oldest Surgical Amputation In One-Legged Skeleton

Archeologists discovered what they believe to be evidence of the oldest known surgical amputation: a 31,000-year-old one-legged skeleton, according to a paper published Wednesday. 

Australian and Indonesian researchers excavated the skeleton in 2020 from a limestone cave in the Indonesian section of Borneo, an island divided between Indonesia, Malaysia, and Brunei. The skeleton, missing its lower left leg, is the oldest known example of surgical amputation, according to a report published in Nature. 

“It was a huge surprise that this ancient forager survived a very serious and life threatening childhood operation,” University of Sydney bioarchaeologist Melandri Vlok said, adding “that the wound healed to form a stump, and that they lived for years in mountainous terrain with altered mobility – suggesting a high degree of community care.” 

Researchers say the amputation was successfully performed on a child, who likely lived between 6 and 9 years after the procedure. The report called the discovery “unexpectedly early evidence” of a successful operation of its kind, leading researchers to believe people of the time, at least in tropical Asia, had medical knowledge and skills not previously attributed to the time period. 

The body’s remains were placed in the Liang Tebo cave on Indonesian Borneo, the third largest island in the world, in the Indonesian province of East Kalimantan. The area is also known for having some of the earliest-dated rock art in the world. 

Prior to this discovery, the earliest known evidence of an amputation “operation” was a 7,000-year-old skeleton of a European farmer’s left forearm, just above the elbow, which was found in France. According to the report, this amputation partially healed and would have required technical skills and knowledge of human anatomy.

Huge megalithic complex of more than 500 standing stones discovered in Spain

A huge megalithic complex of more than 500 standing stones has been discovered in southern Spain that could be one of the largest in Europe, archaeologists have said.

The stones were discovered on a plot of land in Huelva, a province flanking the southernmost part of Spain’s border with Portugal, near the Guadiana River.

Spanning about 600 hectares (1,500 acres), the land had been earmarked for an avocado plantation. Before granting the permit the regional authorities requested a survey in light of the site’s possible archaeological significance. The survey revealed the presence of the stones.

“This is the biggest and most diverse collection of standing stones grouped together in the Iberian peninsula,” said José Antonio Linares, a researcher at Huelva University and one of the project’s three directors. It was probable that the oldest standing stones at the La Torre-La Janera site were erected during the second half of the sixth or fifth millennium BC, he said. “It is a major megalithic site in Europe.”

At the site they found a large number of various types of megaliths, including standing stones, dolmens, mounds, coffin-like stone boxes called cists, and enclosures.

“Standing stones were the most common finding, with 526 of them still standing or lying on the ground,” said the researchers in an article published in Trabajos de Prehistoria, a prehistoric archaeology journal. The height of the stones was between one and three metres.

9,000-year-old ritual complex found in Jordan desert

Archaeologists deep in the Jordanian desert have discovered a 9,000-year-old ritualistic complex near what is thought to be the earliest known large human-built structure worldwide.

The Stone Age shrine site, excavated last year, was used by gazelle hunters and features carved stone figures, an altar and a miniature model of a large-scale hunting trap.

The giant game traps the model represents — so-called “desert kites” — were made of long walls that converge to corral running gazelles into enclosures or holes for slaughter.

Similar structures of two or more stone walls, some several kilometres (miles) long, have been found in deserts across Saudi Arabia, Syria, Turkey and Kazakhstan.

The Neolithic-era ritual site was discovered inside a larger campsite last October by a joint French-Jordanian team called the South Eastern Badia Archaeological Project.

The nearby desert kites in Jibal al-Khashabiyeh are “the earliest large-scale human built structures worldwide known to date,” said a statement by the SEBA Project.

It hailed the “spectacular and unprecedented discovery” of the ritualistic site, believed to date to about 7000 BC.

It featured two steles with anthropomorphic features, the taller one 1.12 metres high, other artefacts including animal figurines, flints, and some 150 arranged marine fossils.

The wider, decade-old research project aims to study “the first pastoral nomadic societies, as well as the evolution of specialised subsistence strategies”.

The desert kites suggest “extremely sophisticated mass hunting strategies, unexpected in such an early timeframe,” said the project’s statement.

The human brain doubled in power, very suddenly, 200,000 years ago. Why?

There seems to have been a profound difference in cognitive abilities between early Homo sapiens and our immediate predecessor, Homo erectus. Sure, erectus stood upright — a big, um, step forward — but with the emergence of Homo sapiens, we see traces of art, pictography, and tool usage, and we believe humankind made its first forays into language.

In the early 1990s, psychedelic advocate and ethnobotanist Terence McKenna published his book Food of the Gods in which he surmised that homo sapiens’ cognitive leap forward was due to their discovery of magic mushrooms. The scientific community never took McKenna’s theory very seriously, considering it mostly trippy speculation — these days, his ideas have largely been relegated to the spacier corners of Reddit. Now, however, the idea has acquired a new advocate, psilocybin mycologist Paul Stamets, who’s suggesting McKenna was right all along.

In McKenna’s Stoned Ape hypothesis,” he posited that as humans began to migrate to new areas, at some point they came upon psychedelic mushrooms growing in cow droppings, as is their wont, and then ate them. After ingesting them, and more specifically the psilocybin they contained, their brains kicked into overdrive, acquiring new information-processing capabilities, and a mind-blowing expansion of our imaginations in the bargain. Many modern users of psychedelics claim the world never looks the same again after such an experience. As McKenna put it, “Homo sapiens ate our way to a higher consciousness,” and, “It was at this time that religious ritual, calendar making, and natural magic came into their own.”

Artificial Intelligence Has Found an Unknown ‘Ghost’ Ancestor in The Human Genome

Nobody knows who she was, just that she was different: a teenage girl from over 50,000 years ago of such strange uniqueness she looked to be a ‘hybrid’ ancestor to modern humans that scientists had never seen before.

Only recently, researchers have uncovered evidence she wasn’t alone. In a 2019 study analysing the complex mess of humanity’s prehistory, scientists used artificial intelligence (AI) to identify an unknown human ancestor species that modern humans encountered – and shared dalliances with – on the long trek out of Africa millennia ago.

“About 80,000 years ago, the so-called Out of Africa occurred, when part of the human population, which already consisted of modern humans, abandoned the African continent and migrated to other continents, giving rise to all the current populations”, explained evolutionary biologist Jaume Bertranpetit from the Universitat Pompeu Fabra in Spain.

As modern humans forged this path into the landmass of Eurasia, they forged some other things too – breeding with ancient and extinct hominids from other species.

Up until recently, these occasional sexual partners were thought to include Neanderthals and Denisovans, the latter of which were unknown until 2010.

But in this study, a third ex from long ago was isolated in Eurasian DNA, thanks to deep learning algorithms sifting through a complex mass of ancient and modern human genetic code.

Using a statistical technique called Bayesian inference, the researchers found evidence of what they call a “third introgression” – a ‘ghost’ archaic population that modern humans interbred with during the African exodus.

“This population is either related to the Neanderthal-Denisova clade or diverged early from the Denisova lineage,” the researchers wrote in their paper, meaning that it’s possible this third population in humanity’s sexual history was possibly a mix themselves of Neanderthals and Denisovans.

In a sense, from the vantage point of deep learning, it’s a hypothetical corroboration of sorts of the teenage girl ‘hybrid fossil’ identified in 2018; although there’s still more work to be done, and the research projects themselves aren’t directly linked.

“Our theory coincides with the hybrid specimen discovered recently in Denisova, although as yet we cannot rule out other possibilities”, one of the team, genomicist Mayukh Mondal from the University of Tartu in Estonia, said in a press statement at the time of discovery.

In tree rings and radioactive carbon, signs of the Vikings in North America

Vikings from Greenland — the first Europeans to arrive in the Americas — lived in a village in Canada’s Newfoundland exactly 1,000 years ago, according to research published Wednesday.

Scientists have known for many years that Vikings — a name given to the Norse by the English they raided — built a village at L’Anse aux Meadows in Newfoundland around the turn of the millennium. But a study published in Nature is the first to pinpoint the date of the Norse occupation.

The explorers — up to 100 people, both women and men — felled trees to build the village and to repair their ships, and the new study fixes a date they were there by showing they cut down at least three trees in the year 1021 — at least 470 years before Christopher Columbus reached the Bahamas in 1492.

“This is the first time the date has been scientifically established,” said archaeologist Margot Kuitems, a researcher at the University of Groningen in the Netherlands and the study’s lead author.

“Previously the date was based only on sagas — oral histories that were only written down in the 13th century, at least 200 years after the events they described took place,” she said.

Six-million-year-old Cretan footprints challenge beliefs about human evolution

A new study has pushed back the estimated age of 50 footprints preserved in rocks on the Mediterranean island of Crete – footprints that were already thought to be among the oldest pre-human prints in the world, and have now been dated to around 6.05 million years ago.

The international team of researchers, whose study was published this week in Scientific Reports, used refined dating techniques to more accurately place the precious imprints in history, but the claims are deeply controversial, challenging prevailing wisdom about human evolution.

Scientists find evidence of humans making clothes 120,000 years ago

From the medieval fashion for pointy shoes to Victorian waist-squeezing corsets and modern furry onesies, what we wear is a window to our past.

Now researchers say they have found some of the earliest evidence of humans using clothing in a cave in Morocco, with the discovery of bone tools and bones from skinned animals suggesting the practice dates back at least 120,000 years.

Dr Emily Hallett, of the Max Planck Institute for the Science of Human History in Germany, the first author of the study, said the work reinforced the view that early humans in Africa were innovative and resourceful

“Our study adds another piece to the long list of hallmark human behaviours that begin to appear in the archaeological record of Africa around 100,000 years ago,” she said.

While skins and furs are unlikely to survive in deposits for hundreds of thousands of years, previous studies looking at the DNA of clothing lice have suggested clothes may have appeared as early as 170,000 years ago – probably sported by anatomically modern humans in Africa.

The latest study adds further weight to the idea that early humans may have had something of a wardrobe.

Writing in the journal i Science, Hallett and colleagues report how they analysed animal bones excavated in a series of digs spanning several decades at Contrebandiers Cave on the Atlantic coast of Morocco. The cave has previously been revealed to contain the remains of early humans.

Hallett said she began studying the animal bones in 2012 because she was interested in reconstructing the diet of early humans and exploring whether there had been any changes in diet associated with changes in stone tool technology.

However, she and her colleagues found 62 bones from layers dating to between 120,000 and 90,000 years ago that showed signs of having been turned into tools.
