Psychedelic Mushrooms May Have Contributed To Early Development Of Human Consciousness, Study Concludes

A new paper exploring the role of psilocybin mushrooms in the evolution of human consciousness says the psychedelic has the “potential to trigger significant neurological and psychological effects” that could have influenced the development of our species over time.

The literature review, which authors said draws on “a multidisciplinary approach spanning biology, ethnobotany and neuroscience,” examined studies involving psilocybin and human consciousness published in multiple journals in different fields. Their 12-page report highlights views that mushrooms played a crucial role in getting humans to where we are today.

“The hypothesis that psilocybin mushrooms may have intervened as a factor in the evolution of human consciousness, either as catalysts of mystical experiences or as drivers of cognitive processes, raises profound reflections on the ancestral interaction between human beings and their environment,” the authors wrote, according to a translation from the original Spanish. “The origin of human consciousness is one of the great questions facing man, and the material collected indicates that psilocybin may have contributed to its early development.”

As humans’ ancestors moved from forested environments into grasslands, they encountered more hoofed animals—and their excrement. In that excrement, they likely found mushrooms, including psilocybin mushrooms, says the study, citing researchers such as Terrence McKenna, who explored the so-called “stoned ape” theory that psychedelics helped spur human development.

Consuming mushrooms may have subsequently influenced pre-human hominids’ brains in all sorts of ways, authors wrote, such as improving hunting and food-gathering as well as increasing sexual stimulation and mating opportunities.

Changes like those, combined with the effects of psilocybin on human consciousness and brain function, could have expanded the human mind, “allowing us to transcend our basic perception and embrace creativity, introspection and abstract thinking” and potentially influencing language development, the study, published last month by the Miguel Lillo Foundation, a research organization in Argentina, says.

“Considering the importance of psilocybin mushrooms in the interaction with human consciousness, it is crucial to explore both their brain and evolutionary implications,” the authors—Jehoshua Macedo-Bedoya of the University Nacional Mayor de San Marcos, in Lima, Peru, and Fatima Calvo-Bellido of the Pontifical Catholic University of Peru—concluded.

EVIDENCE OF ANCIENT HUMAN INTERACTIONS WITH INTELLIGENT “LOST” SPECIES OFFERS CLUES TO THEIR MYSTERIOUS DISAPPEARANCE

New investigations into humanity’s ancient interactions with an enigmatic “lost” species are revealing the complex world our early ancestors once shared.

The recent research conducted by an international team of geneticists and AI experts has revealed that the lives of early modern humans and Neanderthals were more interconnected than previously thought. Significantly, the study points to waves of interbreeding over time that fundamentally shaped the genetic makeup of modern humans and offers new insights into the mysterious disappearance of the Neanderthals.

Led by Joshua Akey from Princeton University, the team says it has discovered evidence of such genetic exchanges dating back as far as 250,000 years. This data challenges existing theories about human migrations in the ancient world and what factors may have steered human evolution over time.

The new findings point to a far deeper level of interaction that once occurred between ancient humans and our Neanderthal cousins.

THE NEANDERTHAL ENIGMA

First discovered in 1856, what eventually came to be recognized as the first known Neanderthal bones were found in a limestone quarry in the Neander Valley near Düsseldorf, Germany. The discovery introduced these mysterious archaic hominins to the paleoanthropological record and prompted serious scientific interest in what factors shaped human evolution over time.

Once mischaracterized as slow and lacking intelligence, mounting evidence of traits exhibited by Neanderthals, including advanced stone toolmaking and the possibility that they may have treated each other’s injuries, is continually reshaping our ideas about their intelligence levels.

While similar to us in many ways, the differences between Neanderthal remains and those of modern humans have long remained intriguing to scientists, raising questions that have deepened in recent years with the discovery of another hominin group, known as the Denisovans, that once also populated parts of Asia and South Asia as recently as the latter part of the last Ice Age.

Now, Akey and his team at Princeton’s Lewis-Sigler Institute for Integrative Genomics are uncovering deeper insights than ever before into the genetic history modern humans share with the Neanderthals, who mysteriously vanished from the fossil record around 40,000 years ago.

According to Akey and his team, multiple different waves of interbreeding between Neanderthals and modern humans appear to have taken place.

“We now know that for the vast majority of human history, we’ve had a history of contact between modern humans and Neanderthals,” Akey recently said.

Liming Li, a professor at Southeast University in China who was also a contributor to the study, called the team’s findings “the first time that geneticists have identified multiple waves of modern human-Neanderthal admixture.”

Unveiling 1,200 years of Human Occupation in Canada’s Arctic

A recent study provides new insights into ancient cultures in Canada’s Arctic, focusing on Paleo-Inuit and Thule-Inuit peoples over thousands of years. Jules Blais, professor of biology at the University of Ottawa, and a team of researchers detected human presence and settlements on Somerset Island, Nunavut, by analyzing sediment samples.

The Arctic has been home to various cultures, such as the Paleo-Inuit (2500 BC to 1250 AD) and the Thule-Inuit (1200 to 1500 AD). Although historical evidence is scarce, this recent study provides valuable insight into their presence.

The study discovered evidence of Paleo-Inuit presence on Somerset Island in Nunavut, Canada, where it was lacking.

The innovative research methodologies revealed detailed information about past human history without traditional artifacts.

Professor Jules Blais says,

“By analyzing pond sediment samples, we were able to construct detailed histories of site occupation. This includes clear evidence of Paleo-Inuit presence and indications that the Thule-Inuit arrived earlier than previously estimated.”

The research used archeological evidence and sedimentary biomarkers to study prehistoric settlement on Somerset Island.

Sediment cores from island ponds were analyzed for trace elements and organic compounds.

Results showed that the Thule-Inuit population increased from the 13th to 15th centuries.

The researchers also showed high levels of metals like lead, copper, zinc and nickel in twentieth-century sediment, suggesting air pollution during that time.

At Least 30 Egyptian Tombs Have Reappeared—and Archaeologists Are Astounded

There are a few questions coming from an archaeological dig on a hillside along the Nile River near the ancient Egyptian city of Aswan. The biggest, though, is exactly why two mummies were glued together inside the same stone coffin.

During a joint Italian and Egyptian archaeological mission working in the vicinity of the Aghakhan Shrine west of Aswan, the team explored the multi-level structure crafted into the hillside. Originally discovered outside of official channels—read: during illegal excavations—the government stepped in and took control.

The joint group dated the site to from 332 B.C. to 395 A.D., somewhere in the late Greek and Roman periods. Ayman Ashmawi—head of the Egyptian archaeological sector of the Supreme Council—said in a news release that the group found what equates to 33 graves, and as many as 40 percent of the remains were from those who died either as newborns or within their first couple of years. They also started discovering some more incredible things, such as the 10-level tomb still containing oil lamps that were potentially left behind by mourners.

“We can imagine how spectacular it was when, for example, during the [mourners’] feast, all these tombs were illuminated,” Patrizia Piacentini—Egyptologist and archaeologist at the University of Milan who led the effort at the site—told Live Science.

Believed to be family graves based on the range of ages of the deceased, the site was likely in use for around 900 years, Piacentini said.

The team discovered several mummies, including two bodies glued to each other inside a stone coffin. The team plans to study the pair to find out their relationship, said Abdul Moneim Saeed, the director of the archaeological mission for the Egyptians.

New study reveals comet airburst evidence from 12,800 years ago

Researchers continue to expand the case for the Younger Dryas Impact hypothesis. The idea proposes that a fragmented comet smashed into the Earth’s atmosphere 12,800 years ago, causing a widespread climatic shift that, among other things, led to the abrupt reversal of the Earth’s warming trend and into an anomalous near-glacial period called the Younger Dryas.

Now, UC Santa Barbara emeritus professor James Kennett and colleagues report the presence of proxies associated with the cosmic airburst distributed over several separate sites in the eastern United States (New Jersey, Maryland and South Carolina), materials indicative of the force and temperature involved in such an event, including platinum, microspherules, meltglass and shock-fractured quartz. The study appears in the journal Airbursts and Cratering.

“What we’ve found is that the pressures and temperatures were not characteristic of major crater-forming impacts but were consistent with so-called ‘touchdown’ airbursts that don’t form much in the way of craters,” Kennett said.

The Earth is bombarded every day by tons of celestial debris, in the form of tiny dust particles. On the other end of the scale are the extremely rare and cataclysmic impacts like the Chicxulub event that 65 million years ago caused the extinction of dinosaurs and other species. Its 150-kilometer-wide (93 miles) impact crater can be found in the Yucatán Peninsula in Mexico.

Somewhere in between are the impacts that don’t leave craters on the Earth’s surface but are nevertheless destructive. The shockwave from the 1908 Tunguska event knocked down 2,150 square kilometers (830 square miles) of forest, as the roughly 40-meter (130 ft) diameter asteroid collided with the atmosphere almost 10 kilometers (6 miles) above the Siberian taiga.

The comet thought to be responsible for the Younger Dryas cooling episode is estimated to have been 100 kilometers wide (62 miles)—much larger than the Tunguska object, and fragmented into thousands of pieces. The sediment layer associated with the airburst stretches across much of the northern hemisphere, but can also be found in locations south of the equator. This layer contains unusually high levels of rare materials associated with cosmic impacts, such as iridium and platinum, and materials formed under high pressures and temperatures, such as magnetic microspherules (cooled-down metallic droplets), meltglass and nanodiamonds.

Hidden ‘City of the Dead’ with more than 300 tombs that contain mummified families is discovered in Egypt

Scientists have discovered a massive burial with more than 300 tombs in Egypt that they are calling the new ‘City of the Dead.’

The city of Aswan was an important trade, quarry and military zone when it was first established more than 4,500 years ago – but the lives of its people have long remained a mystery.

The team has been working at the site for five years and recently uncovered 36 tombs that were reused for 900 years to include 30 to 40 mummies each – and many contained families who likely died from infectious diseases.

Patrizia Piacentini, an archaeologist at the University of Milan, told DailyMail.com that the burial site spans nearly 270,000 feet and featured up to 10 terraces of ancient tombs arranged in layers on the hill near the modern Mausoleum of Aga Khan III.

‘This was a really spectacular find, very unique in Egypt,’ said Piacentini.

‘[The people who once lived in Aswan] covered the hill with tombs. It is kind of a City of the Dead.’ 

Aswan, one of the world’s oldest continuously inhabited cities, is located on the east bank of the Nile River.

It was home to quarries that supplied granite for many ancient Egyptian monuments still standing to this day and was a military post for the Romans, the Turks, and the British.

Easter Island study casts doubt on theory of ‘ecocide’ by early population


Easter Island study casts doubt on theory of ‘ecocide’ by early population

Easter Island has long been put forward as a prime example of humans undermining their own survival by destroying the environment they rely on. But now fresh data is turning the narrative on its head.

Also known as Rapa Nui, the remote island in Polynesia is well known for its huge stone statues called “moai” and for the idea that its growing population collapsed because of “ecocide”.

The theory – promoted by experts including the Pulitzer prize-winning author Jared Diamond – suggests islanders chopped down palm trees at an unsustainable rate to create gardens, harvest fuel and move statues, which brought on disaster. As a result, the population encountered by Europeans in the 18th century was a shadow of what it had once been.

However, a new study has added to a growing body of evidence offering a very different view.

“Our study confirms that the island couldn’t have supported more than a few thousand people,” said Dr Dylan Davis, a co-author of the work from Columbia University. “As such, contrary to the ecocide narrative, the population present at European arrival wasn’t the remnants of Rapa Nui society, but was likely the society at its peak, living at the levels that were sustainable on the island.”

Writing in the journal Science Advances, Davis and colleagues reported how they harnessed high-resolution shortwave infrared and near-infrared satellite imagery and machine learning to identify archaeological sites of rock gardening – a practice employed by the inhabitants of Easter Island to grow crops, including sweet potatoes.

The results suggest only 0.76 km2 of land was used in this way – far below previous estimates which, the team said, misidentified features such natural lava flows.

As a result, Davis and colleagues have suggested that rock gardening alone could only have supported about 3,900 people at most, a long way off previous estimates of up to 17,000. Indeed, the average figure is just 2,000 people, although this could be increased to up to 4,000 people if other foods, for example from fishing or foraging, are considered.

“One of the major arguments for an ‘ecocide’ was that the populations must have been very large in order to build all of the moai statues,” said Davis.

“However, archaeological evidence does not support a large population and studies of the moai themselves suggest that a small population could have built and moved them. It just required cooperation.”

Davis added that while the first people to arrive on Rapa Nui in about AD1200-1250 found an island covered in forest but with limited soil nutrients, it was the arrival of the seed-eating Polynesian rat that caused the tree population to wane.

“When Europeans arrived in the 18th century, they found a society living within their means, growing much of their food in rock gardens in an otherwise unfarmable landscape,” he said.

Prof Sue Hamilton, an expert on Rapa Nui from University College London who was not involved in the work, said the study was not the first to call earlier ideas into question.

She said: “For at least a decade, the idea of ecocide through population growth and landscape mismanagement has been increasingly convincingly challenged for Rapa Nui.”.

600,000 YEARS AGO, A TRANSFER OF ANCIENT KNOWLEDGE KICKED OFF A SUDDEN AND RAPID ADVANCE IN TECHNOLOGY

Early humans appear to have experienced a sudden and rapid advance in technology around 600,000 years ago, according to new findings by a team of anthropologists exploring the use of ancient stone tools.

The researchers behind the findings say this likely represents a key inflection point in ancient human development, where the transfer of ancient knowledge from generation to generation, known as cumulative culture, resulted in increasing advances in society that propelled humanity’s biological, cultural and technological development.

“Our species, Homo sapiens, has been successful at adapting to ecological conditions — from tropical forests to arctic tundra — that require different kinds of problems to be solved,” said associate professor Charles Perreault, an anthropologist from Arizona State University’s School of Human Evolution and Social Change. and a research scientist with the Institute of Human Origins.“Cumulative culture is key because it allows human populations to build on and recombine the solutions of prior generations and to develop new complex solutions to problems very quickly.”

TOOLMAKING SUDDENLY UNDERWENT A RAPID ADVANCE IN TECHNOLOGY

In their published study, “3.3 million years of stone tool complexity suggests that cumulative culture began during the Middle Pleistocene,” which appeared in the journal PNAS, Perreault and fellow author Jonathan Paige, a University of Missouri anthropologist, explain how their analysis of stone tools dating back to 3.3 million years ago revealed this sudden and unexpected technological leap.

The researchers analyzed tools collected from 57 separate ancient hominin sites. The oldest tool, dating back over 3 million years, came from an African site. However, the researchers also studied ancient stone tools discovered at ancient hominin sites in Eurasia, Greenland, Sahul, Oceania, and the Americas.

Next, the team ranked the tools’ complexity. This meant analyzing how many steps would need to be taken to create the tool in question. The researchers characterized and ranked 62 distinct tool-making sequences.

Mysterious 4,000-year-old round stone building on Crete hilltop threatens to disrupt the island’s major airport project

A mysterious 4,000-year-old hilltop structure on the Greek island of Crete has threatened to disrupt plans for a major new airport project on the island. 

Resembling a huge car wheel from above, the ruins of the labyrinthine, 19,000-square-foot building came to light during a recent dig by archaeologists.

Experts believe the ‘unique and extremely interesting find’ was built by Crete’s ancient Minoan civilisation, famous for its sumptuous palaces, flamboyant art and enigmatic writing system.

But the site was earmarked for a radar station to serve a new airport under construction near the town of Kastelli.

Set to open in 2027, it is projected to replace Greece‘s second-biggest airport at Heraklion, and designed to handle up to 18 million travellers annually. 

But Greece’s culture minister Lina Mendoni, an archaeologist, pledged that the find would be preserved while a different location would be sought for the radar station.

9,000-year-old Stone Mask from the Dawn of Ancient Societies Revealed

A rare 9,000-year-old stone mask from the Neolithic period has been unveiled by the Israel Museum in Jerusalem. This remarkable artifact was recovered by the Anti-Robbery Unit of the Israel Antiquities Authority (IAA) and subsequently transferred to the Archaeology Department of the Civil Administration in Judea and Samaria for detailed study. 

The item was originally discovered in Hebron on the West Bank by looters. It comes from a crucial period in the history of humanity – the transition from a nomadic hunter-gathering existence to a settled society based on agriculture. 

The recovery of the mask was thanks to the tenacious efforts of the IAA’s Antiquities Theft Prevention Unit. This is a specialist unit dedicated to the prevention of the looting of archaeological sites and the recovery of stolen antiquities. It received information that a rare stone mask had been illegally excavated in early 2018. Following up on the tip off, the unit soon recovered the mask from the thieves. 

According to the Times of Israel at the time, the investigation indicated that “the probable archaeological site in which the mask was originally found, is in the Pnei Hever region of southern Har Hevron” in the Hebron Hills, not far from the Judean desert. 

The mask is made from limestone and it was smoothed and shaped with great artistry. It resembles a human face and it has details such as cheekbones and even teeth that make it more life-like. The finish of the mask is very impressive, especially given the fact that it was only made with basic tools, and this demonstrates that the society that produced it had sophisticated craft people. There are four holes bored on the edges of the artifact and these were possibly used to tie it around a person’s head, so it could be worn in a ceremony, or else it was attached to a pole and placed on public display.
