Iberian Hunter-Gatherers Were More Sophisticated 9,500 Years Ago Than Previously Known

(p. 6) Hunter-gatherer societies on the Iberian Peninsula were making sophisticated baskets with decorative geometric patterns 9,500 years ago, more than 2,000 years earlier than previously thought, researchers in Spain have reported.

. . .

Francisco Martínez-Sevilla, a researcher of prehistory at the University of Alcalá and the lead author of a paper outlining the findings that was published this week in Science Advances, explained that carbon-14 dating tests had been carried out on 76 objects that were found by 19th-century miners in the Cueva de los Murciélagos, a cave in southern Spain.

The objects, including Europe’s oldest pair of sandals, a wooden stick and mace and exquisitely crafted baskets woven from reed and esparto, were previously believed to have been made by Neolithic farmers.

But the carbon-14 testing carried out by Dr. Martínez-Sevilla’s research group, which has recently excavated human remains in the cave, showed that the best-preserved baskets were, in fact, crafted by hunter-gatherer communities in the Mesolithic era, 9,500 years ago.  . . .

“My first reaction was, ‘Oh my God, that is not possible,’” Dr. Martínez-Sevilla said in a telephone interview, explaining how the discovery suggested that Mesolithic societies may have been more complex than previously imagined. “When we realized the magnitude of the findings, we published the paper with all the analysis in less than a year.”

Global Warming “Presents a Fleeting Opportunity for Glacial Archaeologists”

(p. 14) Espen Finstad was trudging through mud in the Jotunheimen mountains of eastern Norway this month when he happened upon a wooden arrow, bound with a pointed tip made of quartzite. Complete with feathers, it was so well-preserved that it looked as if it could have been lost just recently.

. . .

The find, which Mr. Finstad and his colleagues believe belonged to a reindeer hunter in the late Stone Age or early Bronze Age, is among thousands of artifacts and remains that have emerged from melting ice in recent years, as climate change thaws permafrost and glaciers around the world.

. . .

The thaw presents a fleeting opportunity for glacial archaeologists: They must find the historical treasures just as they emerge from the ice and before they are destroyed by the elements.

“We’re sort of in a race against time,” said Lars Holger Pilo, a glacial archaeologist and a colleague of Mr. Finstad’s.  . . .

For more than a decade, their team, which runs the Secrets of the Ice project, has scoured mountain passes across the country.  . . .

Since then, the team has discovered around 4,000 artifacts and remains, including a 1,000-year-old wooden whisk and Viking mitten, medieval horseshoes, Bronze Age skis and more than 150 arrows.

Similar work is taking place near Anchorage, Alaska, as well as in northeastern Siberia and Mongolia.

Among the most exciting finds have been Yuka, a 39,000-year-old baby Mammoth found in Siberia in 2010, and a 280-million-year-old tree fossil found in Antarctica in 2016. But the most famous of all is Ötzi — a 5,300-year-old iceman found in 1991 by hikers on the northern Italian border with Austria.

Stimulant Ephedrine Was Known and Used in Bronze Age

Ephedrine currently has a variety of medical uses, including as a decongestant.

(p. A4) Bronze Age humans have been credited with a number of civilizational advancements: the invention of irrigation, the wheel, writing systems and the ability to forge weapons and tools from the durable metal that lends the era its name.

Now, strands of human hair discovered in an ancient burial cave in Spain suggest another novelty: a proclivity for consuming psychoactive drugs.

. . .

The findings, published Thursday [April 6, 2023] in Scientific Reports of the journal Nature, provide the first direct evidence that ancient Europeans consumed psychoactive drugs much like their pre-Columbian brethren in Mesoamerica, the researchers said.

Elisa Guerra-Doce, the lead author of the study, said researchers were stunned by the results, especially because the cave interiors yielded no detectable signs of the drugs’ presence. A chemical analysis of the hair revealed evidence of three alkaloid substances known to produce altered states of consciousness: ephedrine, atropine and scopolamine.

The compounds themselves are produced by flora native to Minorca. Atropine and scopolamine, powerful hallucinogens, can be found in plants in the nightshade family, among them mandrake, henbane and thorn apple. Ephedrine, a stimulant, can be extracted from joint pine.

“These findings are so singular,” said Ms. Guerra-Doce, an expert in the anthropology of intoxication at the University of Valladolid in Spain. “Sometimes when people think about drugs, they think it’s a modern practice. These results tell a different story.”

. . .

The three compounds have a long history of human use. Ephedrine is a stimulant that provides bursts of energy and mental clarity, and it can stave off sleepiness. Atropine and scopolamine are powerful deliriants that can produce hallucinations and out-of-body experiences.

Caution in Interpreting Alternative Explanations of Ancient Artifacts

A few weeks ago, an article highlighted the finding of female bones in a burial along with a sword. It was interpreted that the sword belonged to a distinguished female warrior and was interpreted as evidence against patriarchal assumptions.

(p. D1) The epitaph on more than one Roman tombstone read: “A gang of doctors killed me.”

Medical remedies have improved since those times — no more smashed snails, salt-cured weasel flesh or ashes of cremated dogs’ heads — but surgical instruments have changed surprisingly little. Scalpels, needles, tweezers, probes, hooks, chisels and drills are as much part of today’s standard medical tool kit as they were during Rome’s imperial era.

Archaeologists in Hungary recently unearthed a rare and perplexing set of such appliances. The items were found in a necropolis near Jászberény, some 35 miles from Budapest, in two wooden chests and included a forceps, for pulling teeth; a curet, for mixing, measuring and applying medicaments, and three copper-alloy scalpels fitted with detachable steel blades and inlaid with silver in a Roman style. Alongside were the remains of a man presumed to have been a Roman citizen.

The site, seemingly undisturbed for 2,000 years, also yielded a pestle that, judging by the abrasion marks and drug residue, was probably used to grind medicinal herbs. Most unusual were a bone lever, for putting fractures back in place, and the handle of what appears to have been a drill, for trepanning the skull and extracting impacted weaponry from bone.

The instrumentarium, suitable for performing complex operations, provides a glimpse into the advanced medical prac-(p. D4)tices of first-century Romans and how far afield doctors may have journeyed to offer care. “In ancient times, these were comparatively sophisticated tools made of the finest materials,” said Tivadar Vida, director of the Institute of Archaeology at Eötvös Loránd University, or ELTE, in Budapest and leader of the excavation.

Two millenniums ago Jászberény and the county around it were part of the Barbaricum, a vast region that lay beyond the frontiers of the Empire and served as a buffer against possible outside threats. “How could such a well-equipped individual die so far from Rome, in the middle of the Barbaricum,” mused Leventu Samu, a research fellow at ELTE and a member of the team on the dig. “Was he there to heal a prestigious local figure, or was he perhaps accompanying a military movement of the Roman legions?”

. . .

The tool-laden grave was discovered last year at a site where relics from the Copper Age (4500 B.C. to 3500 B.C.) and the Avar period (560 to 790 A.D.) had been found on the surface. A subsequent survey with a magnetometer identified a necropolis of the Avars, a nomadic peoples who succeeded Attila’s Huns. Among the rows of tombs, the researchers uncovered the man’s grave, revealing a skull, leg bones and, at the foot of the body, the chests of metal instruments. “The fact that the deceased was buried with his equipment is perhaps a sign of respect,” Dr. Samu said.

That is not the only possibility. Dr. Baker said that she often cautioned her students about interpreting ancient artifacts, and asked them to consider alternative explanations. What if, she proposed, the medical tools were interred with the so-called physician because he was so bad at his practice that his family and friends wanted to get rid of everything associated with his poor medical skills? “This was a joke,” Dr. Baker said. “But it was intended to make students think about how we jump to quick conclusions about objects we find in burials.”

Small-Brained Early Humans Buried Their Dead and Used Symbols

(p. A16) Discoveries from a subterranean cave system in South Africa are prompting paleoanthropologists to rethink what makes us human. New findings reveal a small-brained human relative known as Homo naledi buried its dead and carved symbols on walls inside the system. Both these behaviors were previously associated with our species or the big-brained Neanderthals with which we interbred.

“We’re looking at cultural behavior that is very human in a species that has a brain a third the size of ours,” said John Hawks, a University of Wisconsin-Madison paleoanthropologist and co-author of the research released Monday [June 5, 2023], which will soon be published in the journal eLife as reviewed preprints. “It is going against the idea that brain size is what made us human.”

. . .

“We’ve never had a creature that manifested the complexity of us that wasn’t us,” said Lee Berger, a paleoanthropologist and an explorer in residence at National Geographic who co-authored the new research. Homo naledi, he added, is “threatening to the very clearly defined narrative of the rise of human exceptionalism.”

Homo Sapiens’s Greater Genetic Diversity May Have Allowed Them to Adapt to Climate Change Faster than Neanderthals

(p. D5) Scientists have revealed a surprisingly complex origin of our species, rejecting the long-held argument that modern humans arose from one place in Africa during one period in time.

By analyzing the genomes of 290 living people, researchers concluded that modern humans descended from at least two populations that coexisted in Africa for a million years before merging in several independent events across the continent. The findings were published on Wednesday [May 24, 2023} in Nature.

“There is no single birthplace,” said Eleanor Scerri, an evolutionary archaeologist at the Max Planck Institute for Geoarchaeology in Jena, Germany, who was not involved in the new study. “It really puts a nail in the coffin of that idea.”

. . .

The researchers concluded that as far back as a million years ago, the ancestors of our species existed in two distinct populations. Dr. Henn and her colleagues call them Stem1 and Stem2.

About 600,000 years ago, a small group of humans budded off from Stem1 and went on to become the Neanderthals. But Stem1 endured in Africa for hundreds of thousands of years after that, as did Stem2.

If Stem1 and Stem2 had been entirely separate from each other, they would have accumulated a large number of distinct mutations in their DNA. Instead, Dr. Henn and her colleagues found that they had remained only moderately different — about as distinct as living Europeans and West Africans are today. The scientists concluded that people had moved between Stem1 and Stem2, pairing off to have children and mixing their DNA.

. . .

It’s possible that climate upheavals forced Stem1 and Stem2 people into the same regions, leading them to merge into single groups. Some bands of hunter-gatherers may have had to retreat from the coast as sea levels rose, for example. Some regions of Africa became arid, potentially sending people in search of new homes.

Even after these mergers 120,000 years ago, people with solely Stem1 or solely Stem2 ancestry appear to have survived. The DNA of the Mende people showed that their ancestors had interbred with Stem2 people just 25,000 years ago. “It does suggest to me that Stem2 was somewhere around West Africa,” Dr. Henn said.

. . .

Dr. Scerri speculated that living in a network of mingling populations across Africa might have allowed modern humans to survive while Neanderthals became extinct. In that arrangement, our ancestors could hold onto more genetic diversity, which in turn might have helped them endure shifts in the climate, or even evolve new adaptations.

“This diversity at the root of our species may have been ultimately the key to our success,” Dr. Scerri said.

Growing Research Suggests Neanderthals Were More Similar to Homo Sapiens in Behavior

(p. A16) Neanderthals might be getting a bad rap. In the movie “Night at the Museum,” when the exhibits come to life after sundown, the Neanderthals are depicted as dimwitted cave men who grunt and bash rocks together in futile attempts to generate a flame. When Ben Stiller’s night-guard character gives them a lighter, one promptly sets himself on fire.

Popular culture has often depicted our Neanderthal cousins much like these museum cave men—also-rans and unsophisticated brutes whose nomadic-hunter lifestyle precluded them from social gatherings and might have contributed to their demise.

But the past decade or so has changed our understanding of Neanderthals. A growing body of research shows these extinct relatives—who overlapped in time and space with anatomically modern humans, or Homo sapiens—were similar to us in many ways. Recent studies suggest Neanderthals altered the landscape around them with fire and were sophisticated hunters who could exploit a variety of prey in groups larger than paleoanthropologists once thought.

Studies show the species used fire to cook, constructed tools to manipulate meat and stone, built structures and made jewelry. They swam and dove for shells, which they used as tools and beads, and distilled birch bark to make tar. Neanderthals decorated and engraved bones and used red ochre—a natural clay pigment—to alter surfaces.

“The more we learn about Neanderthals, the more similar they look to us behaviorally,” said Chris Stringer, research leader in human origins at the Natural History Museum in London.

Marine Life Turns Man-Made Artifacts into a Biodiverse Habitat

(p. 21) Kirstin Meyer-Kaiser, a marine biologist at the Woods Hole Oceanographic Institution, who . . . has studied the connection between underwater sites and marine biodiversity, said that leaving human artifacts in place was also likely better for any marine wildlife. “It was not supposed to be there in the first place,” she said of the relics. “But after a certain amount of time, any man-made object turns into a habitat.”

Scientists Resurrect “Sweet and Possibly Medicinal” Judean Date Palm Pushed to Extinction by Roman Soldiers

(p. C11) The Judean date palm, prized for its sweet and possibly medicinal fruits, had been a feature of the landscape of biblical Israel. In the aftermath of the failed Jewish rebellion at the fortress of Masada in A.D. 73, Roman soldiers set about destroying the date trees, . . .

. . .

The few remaining Judean palms eventually died out. Yet the species wasn’t gone forever, as Martin Lemelman tells children in a captivating graphic novel,”The Miracle Seed.”

With economical text and expressive panel illustrations, Mr. Lemelman recounts the story of the tree’s astounding 21st-century resurrection. Among the detritus left at Masada, he explains, was an earthenware jar containing six Judean palm seeds.

“The Miracle Seed” not only reads like an adventure but also exudes an optimism of the kind that children ages 8-14 deserve.

Long-Distance Trade May Help Explain Why Sapiens Flourished More Than Neanderthals

(p. 47) Sykes explains that Neanderthals were sophisticated and competent human beings who adapted to diverse habitats and climates.

. . .

At the time when they encountered the Neanderthals, Sapiens too lived in small bands, but different Sapiens bands probably cooperated on a regular basis. There is much more evidence for long-distance trade among Sapiens, and spectacular burials like the 32,000-year-old Sunghir graves clearly reflect the combined effort of more than one band.

Large-scale cooperation did not necessarily mean that a horde of 500 Sapiens united to wipe out a band of 20 Neanderthals. Cooperation isn’t just about violence. Sapiens could more easily benefit from the discoveries and inventions of other people. If somebody in a neighboring band discovered a new way to locate beehives, to make a tunic or to heal a wound, such knowledge could spread much more quickly among Sapiens than among Neanderthals. While individual Neanderthals were perhaps as inquisitive, imaginative and creative as individual Sapiens, superior networking enabled Sapiens to swiftly outcompete Neanderthals.

This, however, is largely speculation. We still don’t know enough about the psychology, society and politics of Neanderthals to be sure. Perhaps the most surprising fact in Sykes’s book is that even if we count every bone fragment and every isolated tooth, so far we have found the remains of fewer than 300 Neanderthals.

Scientists Find Evidence of “Defunct Nile Tributary” That Was Close to Pyramid Site, Allowing Transport of Two-Ton Blocks

(p. D5) For 4,500 years, the pyramids of Giza have loomed over the western bank of the Nile River as a geometric mountain chain. The Great Pyramid, built to commemorate the reign of Pharaoh Khufu, the second king of Egypt’s fourth dynasty, covers 13 acres and stood more than 480 feet upon its completion around 2560 B.C. Remarkably, ancient architects somehow transported 2.3 million limestone and granite blocks, each weighing an average of more than two tons, across miles of desert from the banks of the Nile to the pyramid site on the Giza Plateau.

Hauling these stones over land would have been grueling. Scientists have long believed that utilizing a river or channel made the process possible, but today the Nile is miles away from the pyramids. On Monday, however, a team of researchers reported evidence that a lost arm of the Nile once cut through this stretch of desert, and would have greatly simplified transporting the giant slabs to the pyramid complex.

Using clues preserved in the desert soil, the scientists reconstructed the rise and fall of the Khufu Branch, a now defunct Nile tributary, over the past 8,000 years. Their findings, published in the Proceedings of the National Academy of Sciences, propose that the Khufu Branch, which dried up completely around 600 B.C., played a critical role in the construction of the ancient wonders. “It was impossible to build the pyramids here without this branch of the Nile,” said Hader Sheisha, an environmental geographer at the European Center for Research and Teaching in Environmental Geoscience, and an author of the new study.
