The Archaeology of Marijuana

In June, monthly sales for recreational and medical marijuana in my hometown of Colorado reached a record high of $199 million .

The industry’s growth took eight years. In 2012, with the passage of the 64th Amendment, Colorado, along with Washington, became one of the first states in the U.S. where consenting adults could legally purchase and consume marijuana for recreational purposes.

Since then, Colorado’s tourism landscape has changed dramatically. Legalization of recreational marijuana has fueled six of the eight consecutive years of record growth in the tourism industry. In June 2019, the Colorado Department of Revenue announced that total marijuana-related revenue had reached $1 billion since sales began in 2014. This funding has generated hundreds of millions of dollars in new tax revenue for the state, which can be used for education, transportation, environmental protection, and other initiatives.

However, despite the clear economic benefits, many in the United States oppose marijuana legalization. Some of my friends dislike the smell of marijuana. Others are concerned about marijuana use among teenagers, the potential effects of secondhand smoke on children, or people driving under the influence.

I haven’t smoked cigarettes in years, and I’ve never tried edible marijuana. However, I’m very pleased that America is starting to move away from its long road of unnecessarily criminalizing mild recreational drugs.

I voted in favor of Amendment 64 because I oppose the double standards regarding alcohol in the United States. Studies show that alcohol is far more dangerous than marijuana. I also voted in favor because I oppose the systemic racism in the justice system that unfairly punishes people of color for drug-related crimes .

My perspective as an archaeologist is relevant to this matter. I pay close attention to what humanity has done in the past, and from the long-term perspective of human history, I know that not everything in the present is “normal.” The modern fear of marijuana is one of the concerns that seems particularly strange, because researchers estimate that humans have been using cannabis for at least 10,000 years.

What do scholars say about the long history of human use of cannabis? How did cannabis transform from a plant highly valued in many parts of the world to a notorious drug?

What a piece of 15,0000-year-old jewellery found in a Devon cave tells us about this prehistoric ‘civilization’

A piece of prehistoric jewellery, discovered in a West Country cave, is helping to shed new light on Stone Age Europe’s most spectacular culture.

Known as the Magdalenian, that 21,000 to 13,000 year old prehistoric ‘civilization’ dominated much of Western Europe, particularly southwest France, northern Spain and parts of Britain and Germany for most of the final 10,000 years of the Ice Age. A detailed scientific analysis of the British Magdalenian jewellery item, carried out at University College London and the Natural History Museum, has now revealed that it was a polished pendant made from a seal’s tooth.

It’s the first such artefact identified in Britain – and only the fourth anywhere in Europe.

The discovery adds to the substantial evidence showing that Stone Age Magdalenians were extremely fashion-conscious – and that they had a particularly strong preference for maritime-originating jewellery.

For, as well as the four seal-tooth pendants, many sites across Europe, often located far from the sea, have yielded literally thousands of marine shells, virtually all of which would have been used as personal adornments (as pendants, like the seal tooth – but also to beautify clothing and for use in necklaces, bracelets, anklets and headwear).

The scientific investigation into the British artifact (found in Kent’s Cavern, Torquay, Devon) has identified it as a premolar tooth of a grey seal, that had been polished and perforated by a Magdalenian artisan, using a handheld flint boring tool. Microscopic analysis of the wear pattern in the hole has revealed that the tooth had been worn as a pendant, suspended on some sort of cord. The wear, caused by the cord, was so substantial that the pendant appears to have been worn for many years or even decades.

Indeed, it’s conceivable that it may have been a valued heirloom, worn successively by several generations of the same family. Its value and significance to the Kent’s Cavern Magdalenian community – probably an extended family living there seasonally for many generations – is underlined by the fact that the seal tooth would have had to have initially been imported from the seashore which in Magdalenian times was between 50 and 100 miles away.

However, there would have been a direct river connection between the Kent’s Cavern area and the sea – along the river Teign’s prehistoric lower course (now submerged under the English Channel) and then along a now long-vanished major prehistoric waterway, dubbed the Channel River by archaeologists, to the Atlantic. In Magdalenian times, the Thames, the Rhine and the Seine were merely that Channel River’s major tributaries.

Even when living hundreds of miles from the sea, Magdalenian people had a strong cultural connection to it.

Via the Channel River and its many tributaries, they had an easy and direct connection to the Atlantic. They used large numbers of periwinkle, European cowrie and so-called ‘tusk’ shells as well as fossilised molluscs, sea urchin spines and sharks’ teeth to make jewellery and other adornments.

Like ordinary Atlantic seashells, these fossils must have been highly valued because they were often imported from hundreds of miles away. Shells were also imported to inland Magdalenian sites in France, Spain, Germany and Czechia from the Mediterranean. Some had travelled up to 600 miles.

Early humans in South Africa were quarrying stone as far back as 220,000 years ago

As long as 220,000 years ago—far earlier than previously thought—people quarried rocks for their tools in places they specifically sought out. An international research team led by the University of Tübingen has demonstrated this behavior at the Jojosi site in South Africa, challenging the prevailing view that Paleolithic hunter–gatherers collected their raw materials incidentally during other activities. The study is published in the journal Nature Communications.

Evidence of deliberate rock quarrying

“At Jojosi, we found numerous traces of the quarrying of hornfels—a metamorphic shale—including blocks that were tested for their quality, flakes of various sizes, thousands of millimeter-sized pieces of production waste and hammerstones,” says Dr. Manuel Will from the Department of Early Prehistory and Quaternary Ecology at the University of Tübingen. Hornfels is a fine-grained rock that was frequently used to produce tools in the Stone Age. “People worked cobbles on site here and knapped the material until they had achieved the desired shape from the rock—probably to make tools from it later.”

The researchers almost exclusively found “production waste” here. The absence of both the end products and other traces of activity and settlement indicate that the people of Stone Age Jojosi were solely and deliberately seeking to extract the coveted raw material. Remarkably, they were doing this for tens of thousands of years, at least until 110,000 BCE, as can be seen from the luminescence dating of the finds. Given its great age and long period of use, Jojosi adds new facets to the image of early Homo sapiens, indicating that they planned the long-term acquisition of resources much earlier than previously thought.

Archaeologists Are Mystified by These 2,000-Year-Old Bodies Found Seated Upright and Facing West in France

In 2024, archaeologists in France discovered an unusual grave site that contained 13 sets of human remains. All of the individuals appeared to have been buried sitting upright and facing west—a highly unusual and puzzling position.

Now, the researchers say they’ve identified at least five additional seated burials in a previously unexplored area of the same site. The latest discoveries raise more questions about the culture these individuals belonged to more than 2,000 years ago.

According to a March 18 statement from the French National Institute for Preventive Archaeological Research (INRAP), the team unearthed the skeletons while conducting excavations during ongoing renovations of the Josephine Baker primary school complex in Dijon, located in France’s east-central Burgundy region.

Just like the remains found in 2024, the newly discovered individuals were interred upright in a seated position, with their faces turned west and their hands resting in their laps. At least three appear to have been buried in a line parallel to the initially identified graves, about 66 feet away.

Bronze Age Artifact Made from ‘Space Metal’ Unearthed at a Sacrificial Site is Confirmed as the Oldest of Its Kind

A curious Bronze Age artifact unearthed at a ceremonial site in southwestern China has now been identified as the earliest known and the largest of its kind, according to newly published research.

Crafted from meteoritic iron, the rare discovery, described as resembling an “axe-like” instrument, was found at the Sanxingdui site in China’s Sichuan Province, one of the country’s most famous archaeological areas. The confirmation of the artifact’s age offers unique new perspectives on metallurgical practices that occurred early in Bronze Age China.

Discovery at Sanxingdui

Sanxingdui, which archaeologists believe was active from 2800 to 600 BCE, is renowned for the early evidence of industrial practices they have uncovered there, as well as its ancient sacrificial pits and other ceremonial features.

A range of items crafted from bronze have been recovered as well, and in the case of the meteoritic iron blade, analysis has shown that the object was crafted in a period that predates the use of iron smelting in this part of the world.

A key indication of the extraterrestrial origin of the metal used to craft the artifact is its high concentrations of nickel and iron, which appear to rule out the use of early smelting techniques.

While this strongly supports that the object was crafted from meteoritic iron, Dr. Zishu Yang, the co-author of a recent study detailing the discovery, recently said in a statement that current analysis is “insufficient to definitively classify the specific type of meteorite,” and that the exact variety of meteorite the material was sourced from remains unknown.

Going forward, additional analysis that Yang and his colleagues plan to undertake may help reveal further clues, including possible correlations between the unique artifact, its discovery location, and ancient Chinese historical records that may document meteorite impacts from which the iron could have been sourced.

Archaeologists achieve a historic milestone by dating French cave paintings with carbon-14 for the first time

A team led by a researcher from the National Center for Scientific Research (CNRS) has achieved a milestone in prehistoric archaeology by confirming through absolute dating the age of several parietal representations from the Font-de-Gaume cave, located in Dordogne, France.

The results, published in the journal Proceedings of the National Academy of Sciences (PNAS), represent the first time precise dates have been obtained for Paleolithic rock art in this region using the carbon-14 technique, something that until now had been considered unfeasible due to the chemical composition traditionally attributed to the pigments.

Until this study, there had been a widespread technical impossibility in reliably dating the cave paintings of the region, including the famous ones from Lascaux. The main reason lay in the assumption that the black lines had been made exclusively using iron and manganese oxides, mineral compounds that do not contain carbon and therefore cannot be dated through radiocarbon methods.

However, the research team found that no systematic empirical verification had ever been carried out to confirm the complete absence of carbon-based materials in those paintings. To resolve this uncertainty, the scientists decided to apply a non-invasive analysis protocol to two specific black motifs from the Font-de-Gaume cave: the figure of a bison and a design interpreted as a possible anthropomorph or mask.

The methodology used combined two advanced chemical characterization techniques. On the one hand, the researchers employed Raman microspectrometry, a technique that allows the identification of the molecular composition of materials through the interaction of light with the chemical bonds of the sample. On the other hand, hyperspectral imaging was used, a technology that measures the reflectance of light at every point on the analyzed surface and makes it possible to deduce the chemical composition of the coloring compounds present.

Controversial Study Challenges Age of Famous Monte Verde Site, Reigniting One of Archaeology’s Greatest Debates

It began like many archaeological discoveries in the Americas: woodcutters working along the banks of Chinchihuapi Creek, a tributary of the Maullín River about 36 miles from the Pacific coast of southern Chile near Puerto Montt, observed the bones of very large animals protruding from an eroded bank.

The investigations that followed, however, beginning in the 1970s at what became known as the Monte Verde archaeological site, revealed more than just the dwelling place of some of Chile’s earliest residents. Findings there, including radiocarbon dates indicating a human presence as early as 14,500 years ago, led to a controversy that shook the foundations of American anthropology, upending past thinking on not only who had been the first to arrive at sites like this one—now a proposed UNESCO World Heritage Site—but more fundamentally, whether people initially migrated into the Americas far earlier than previously ever imagined.

For many years, the debate over whether sites like Monte Verde provided unequivocal evidence that there were people in the New World prior to the appearance of the Clovis culture—long recognized as the oldest confirmed cultural manifestation in the Americas, and dating to no earlier than around 13,500 years ago—remained one of American archaeology’s most challenging questions.

With time, however, and a growing number of similar discoveries at sites in North and South America that would follow, the debate appeared to have been settled: pre-Clovis had become the accepted paradigm, and the scientific data first uncovered by archaeologist Tom Dillehay, Ph.D, at Monte Verde clearly showed it.

However, that doesn’t mean there haven’t been a few holdouts who continue to argue that the once widely accepted “Clovis horizon” may still be closer to the mark, in terms of when the first large-scale migrations into the Americas began. While their numbers have diminished somewhat within the 21st century, some archaeologists like Dr. Todd Surovell, a Professor and Department Head of the Department of Anthropology at the University of Wyoming, have kept the debate alive by challenging what he and a few colleagues view as a kind of new orthodoxy that has slowly emerged out of what was once considered a fringe idea in American archaeology.

Now, as evidenced by a recent study by Surovell and several co-authors published in Science, not only is the debate still burning after many decades, but the enigmatic Monte Verde archaeological site appears to have maintained its place at the center of the controversy.

Did Archaeologists Uncover Evidence of a Neanderthal “Skull Cult” in This Ancient Spanish Cave?

Archaeologists in central Spain report the puzzling discovery of a collection of ancient animal skulls found deep within an ancient cave near Madrid.

The unusual find is believed to represent evidence of repeated activity carried out tens of thousands of years ago by Neanderthals who once lived in the region, and may offer compelling evidence of symbolic behavior previously thought to be unique to modern humans.

The discovery was detailed in recent research published in Archaeological and Anthropological Sciences.

Discovery at the “Valley of the Neanderthals”

During excavations beginning in 2009, archaeologists uncovered a rich layer of Middle Paleolithic artifacts within Des-Cubierta Cave, located in Pinilla del Valle near Madrid, Spain. Since that time, the area has been dubbed the “Valley of the Neanderthals” for the remarkable ancient discoveries there.

Such finds include the recovery of several Mousterian stone tools—the primary culture of Middle Paleolithic Europe, as recognized by archaeologists—and a technological manifestation widely associated with Neanderthals in Europe.

Stone tools were not all that the cave had shielded against the elements for several tens of thousands of years: the additional presence of a concentration of animal crania added a layer of archaeological significance unlike those found at other European sites linked to the mysterious Neanderthals.

An Accumulation of Ancient Mammal Skulls

Altogether, portions of skulls associated with 35 large animals, including 28 cattle, five species of deer, and two ancient Ice Age rhinoceroses, were discovered in the cave. Curiously, no other skeletal remains from these animals were present, which included even jaws and facial bones that might normally be associated with the discovery of skulls from such animals under other circumstances.

Several questions lingered about whether natural conditions, such as flooding, might have carried the remains into the cave. However, the seemingly obvious implication, based on the very specific selection of only upper crania present within the cave, had been that the skulls were placed there intentionally at some point in the remote past. If so, why had the cave’s ancient visitors done this, and what might it potentially mean?

Evidence of a Neanderthal Skull Cult?

To answer such questions, the research team behind the investigation, led by archaeologist Lucía Villaescusa of the University of Alcalá, closely examined deposits in the cave, ranging from geological debris to fragmented bones. By mapping the distribution of artifacts and reconstructing bone fragments, the team discerned and analyzed preservation patterns to determine how the remains were brought to the cave.

During their investigations, the team found evidence of an ancient rockfall event that created a sloping, conical debris area. Significantly, it was only after this that evidence of skulls began to appear within the cave.

‘Absolute surprise’: Homo erectus skulls found in China are almost 1.8 million years old — the oldest evidence of the ancient human relatives in East Asia

Three Homo erectus skulls previously unearthed in China are almost 1.8 million years old, around 600,000 years older than originally thought, a new study finds.

This revelation has made the Yunxian skulls from Hubei province the oldest evidence of our early human relatives, known as hominins, in East Asia, according to research published Wednesday (Feb. 18) in the journal Science Advances.

Study co-author Christopher Bae, a professor of anthropology at the University of Hawaii at Manoa, told Live Science in an email that he felt “absolute surprise” when he first saw the results of the analysis. This more ancient age may force experts to rethink the date that H. erectus first emerged, which is believed to have occurred around 2 million years ago in Africa.

“What this means is that we need to consider pushing the origin of Homo erectus back” to around 2.6 million years ago, Bae said in an email.

H. erectus has long been considered the first human relative to leave Africa, with 1.78 million to 1.85 million-year-old fossils found at the Dmanisi site in Georgia being the earliest evidence of humans in Asia. But stone tools discovered at two sites in China dated to 2.1 million and 2.43 million years ago have complicated that picture, since they predate experts’ theory of when H. erectus originated.

The exact date of the three Yunxian skulls, which were found between 1989 and 2022, has long been debated, but they were previously considered to be around 1 million years old based on the age of animal teeth found close by, although one study dated them to around 1.1 million years ago using electron spin resonance and uranium-series dating. So when the opportunity arose to try a new dating technique at the site, Bae and his colleagues thought it was a good chance to revisit the debate.

Their team used a technique called cosmogenic nuclide burial dating to determine the age of the quartz found in the sediment layers where the skulls were found. This dating technique measures the half-life of two chemical variants — Aluminum-26 and Beryllium-10 — to determine how much time has passed since the quartz was exposed to cosmic rays.

5,300-Year-Old Egyptian Artifact Confirms Existence of “Mechanically Sophisticated” Drilling Technology Before the Age of the Pharaohs

Close to a century ago, researchers unearthed a small, unusual metal object during excavations at a cemetery in Upper Egypt. Now, a reinvestigation into the curious find has identified it as the earliest known rotary drill ever found in association with ancient Egyptian archaeology.

The small artifact, which measures less than 64 millimeters across and weighs under two grams, is crafted from copper-alloy and dates to the late 4th millennium BCE, which coincides with Egypt’s Predynastic period, a remote era that predates the reign of the earliest pharaohs.

The remarkable discovery, which experts now characterize as “a mechanically sophisticated drilling tool,” was recently detailed in a study published in the journal Egypt and the Levant.

 An Ancient Curiosity Comes into Focus

The small artifact, retrieved from the burial of an ancient predynastic Egyptian man identified as Grave 3932, was first documented in the 1920s. At that time, the object was described as “a little awl of copper, with some leather thong wound round it,” a description that offered researchers little to go on as to what its potential use might have been.

Now, according to a team of archaeologists at Newcastle University, working in collaboration with the Academy of Fine Arts in Vienna, re-examination of the object under magnification has revealed wear patterns that are consistent with drilling devices from later periods in Egyptian history.

Specifically, the team points to evidence of edges rounded from wear, as well as striations and other features that are clear indicators of rotary motion.

“The ancient Egyptians are famous for stone temples, painted tombs, and dazzling jewelry, but behind those achievements lay practical, everyday technologies that rarely survive in the archaeological record,” said Dr. Martin Odler, a Visiting Fellow in Newcastle University’s School of History, Classics and Archaeology, in a statement.

According to Odler, the lead author of the recent study that reassessed the artifact, one of the most important technologies behind such famous achievements afforded us by the ancient Egyptians was the drill, which had uses in everything from woodwork to shaping stone for construction and the creation of decorative pieces.

Evidence of a Bowstring Emerges

Intriguingly, the early 20th-century references to “some leather thong” have proven correct, as the Newcastle team and their Italian collaborators say that six coils of a very fragile piece of leather cordage appear to represent clear evidence of a bowstring which would have been used to power the drill.

Such ancient bow drills served as an early form of rotary tool, which one could liken to an ancient counterpart to modern hand drills. To function, these bow drills featured a small length of leather wrapped around a shaft, which spins the drill very quickly as the string is moved back and forth.
