Pollen records show the landscape was dominated by pasture animals, suggesting the presence of nomadic herdersDIMITRIOS TILIS/Getty Omages
An analysis of pollen from Lake Volvi in Greece has unexpectedly revealed that nomads thrived in this region for centuries after the chaos unleashed by the collapse of the Roman Empire.
Adam Izdebski at the Max Planck Institute of Geoanthropology in Germany and his colleagues were studying sediment cores from the lake as part of a larger study. As lake sediments build up, changes in the abundance of various kinds of pollen in the sediment layers can record how nearby vegetation changed over time.

In some other places around the Mediterranean, the team has found signs of reforestation after the collapse of the Western Roman Empire around AD 476. But at Lake Volvi, from around AD 540, the team found less tree pollen but more pollen from plants associated with nomadic livestock herders. These nomads were returning to the same areas seasonally, so planted some crops, such as barley.
“We have this moment when the Roman agriculture disappears almost completely due to plague, climate change and warfare, but you don’t get reforestation – you actually get less forest very quickly,” says Izdebski.
“The landscape was dominated by pasture animals even in the high mountain areas. This was a complete shift from how the Romans farmed the lowlands for several hundred years.”
This means those earlier farmers moved away, died or adopted a nomadic lifestyle, he says.
Greece was nominally under the control of the Eastern Roman, or Byzantine, Empire around at the time of this shift. It is known that the region was raided by Bulgar nomads around AD 540, but it wasn’t known that nomads lived in this region for several centuries.
The only historical information that correlates with the team’s findings is an account of a Byzantine emperor being ambushed by Bulgar nomads around AD 700.
“It seems that there was a local society that didn’t want any emperor to be around,” says Izdebski, who presented the findings at the meeting of the European Geosciences Union in Vienna, Austria, last month.
Around AD 850, the Byzantine Empire reasserted control and the signs of nomads disappear. Instead, there was reforestation.
The findings provide rare evidence of the presence of nomadic peoples at a particular place and time, says Izdebski. “We know very little about their history because the states were not interested in recording them.”
Historians didn’t write about nomadic peoples as they weren’t part of the elites, he says. And because nomads were difficult to tax, there are no tax records either – tax records can be a rich source of information about past populations.

The Red Pyramid at Dahshur in Egypt was one of many built close to a lost branch of the NileEman Ghoneim
Many of the pyramids of ancient Egypt were built along a now extinct branch of the river Nile, geological surveys have revealed. This could explain why these pyramids, including the famed Great Pyramid of Giza, are clustered in a thin strip of arid, inhospitable land.
“Since ancient times, the Nile has provided sustenance to Egyptian settlements, and it functions as the main water corridor that allowed for the transportation of goods and building materials in the past,” says Tim Ralph at Macquarie University in Sydney, Australia. “For this reason, most of the key cities and monuments were built in close proximity to the banks of the Nile and its peripheral branches.”

More than 100 pyramids were constructed between 4700 and 3500 years ago as grand tombs for Egypt’s pharaohs. Thirty-one of these, including the pyramids of Dahshur, Giza and Saqqara, are dotted along the edge of Egypt’s Western desert, several kilometres away from the Nile.
To transport the enormous number of people and resources necessary to build these pyramids, researchers have long thought that the Nile may have once had an offshoot that flowed by the construction sites.
To investigate further, Ralph and his colleagues looked at radar satellite imagery and land elevation data of the region. Depressions in the landscape indicated that the old water channel may have stretched 64 kilometres past the pyramid fields between the northern city of Giza and the village of Lisht in the south. It was also close to the ancient Egyptian capital of Memphis and the Abusir, Saqqara and Dahshur pyramid complexes.
Once the researchers had a rough idea of the branch’s location, they took soil and sediment core samples along its path and discovered a riverbed of sand hidden under what is now farmland or desert.
“We guess that it was roughly between 200 and 700 metres wide, and at least 8 metres deep at its deepest,” says Ralph.
Causeways that have been found around the 31 pyramids seem to end at the banks of this ancient Nile branch – a sign that the water channel was used to transport building materials thousands of years ago.
The ancient offshoot, dubbed the Ahramat branch after the Arabic word for pyramid, eventually dried up after a severe drought hit the region around 4200 years ago, says Ralph.

“The existence of the channel is an excellent result,” says Penny Wilson at Durham University, UK. “Mapping all of this is a wonderful addition to the ancient landscape that has been buried and shows a cost-efficient way to reconstruct and re-evaluate the economic and social systems of the pharaonic state.”
Campbell Price at the University of Liverpool, UK, says: “I think people often imagine Egyptian pyramids being marooned in the middle of the desert.”
“This research seems to further demonstrate that they were in fact closely connected with the agricultural life of pharaonic Egypt – and the river Nile,” he says.

Humans have an exceptional ability to run long distancessportpoint / Alamy Stock Photo
Before the advent of rifles, many cultures around the world hunted by pursuing prey over long distances. The energy gained by hunting in this way can far exceed the energy spent running, researchers have found, strengthening the argument that humans evolved for endurance running.
“I think our paper makes a very strong case for its importance in the past,” says Eugene Morin at Trent University in Canada. “Something that was thought to be marginal is now shown to be a common strategy worldwide.”

Humans are exceptional endurance athletes, capable even of outrunning animals such as horses over distances of tens of kilometres. We have muscles built for stamina rather than power, and can keep cool by sweating a lot.
“These traits can only be explained in the context of running,” says Morin. “And there are not many reasons for humans to run for long distances other than hunting.”
It has been suggested that humans evolved to chase prey until the prey became too exhausted or overheated to run any further.
This idea, known as the endurance running hypothesis, has been hotly debated. One criticism is that running uses a lot of energy compared with walking. Another is that there are hardly any reports of modern humans using this hunting technique, suggesting it isn’t very efficient.
So, Morin and Bruce Winterhalder at the University of California, Davis, first estimated the energy expended to catch prey during persistence hunting versus the energy gained by catching prey of various sizes. For all but the smallest prey, running beats walking, according to their modelling.
That’s because running doesn’t use much more energy per kilometre but can greatly shorten the duration of a chase. Running 4 kilometres to catch an animal is more efficient than walking 8 kilometres, for instance.
In practice, walking wouldn’t usually work at all, says Morin, because endurance hunting often relies on pushing prey so hard that they overheat. “In most cases, this requires running,” he says.
Morin and Winterhalder also searched through accounts of various peoples written by anthropologists or missionaries from the 1500s onwards. They found around 400 descriptions of endurance hunting from all over the world, most from before 1850.
For example, an account of the Beothuk people of Newfoundland describes a lengthy pursuit of a stag. “The stag at first easily outstrips his pursuer, but after a run of four or five miles he stops and is by and bye [sic] overtaken; again he sets off, and again he is overtaken; again, and again, he is overtaken,” it says. Another account describes endurance hunting of herds of goats in Hawaii.
Running over snow
To Morin’s surprise, there were also accounts from colder regions, whereas previously known examples were from hot, arid regions. “We hunted the moose by running him down on snowshoes, and we could run all day, such as wolves,” an individual of the Gwichʼin people of Alaska and Canada is reported as saying.
The ideal conditions for this were thick snow with a crust strong enough to support a person wearing snowshoes but not strong enough to support heavier prey, says Morin.
He also points out that being able to run long distances used to be a highly valued ability, with numerous accounts of long-distance running races being part of the culture of peoples all around the world.
“It’s hard to argue with the results of their analysis, which clearly support other anatomical, physiological, archaeological and genetic evidence that humans evolved to run long distances to hunt,” says Daniel Lieberman at Harvard University, one of the proponents of the endurance running hypothesis. “Until the invention of modern technologies, persistence hunting by endurance running was widespread and very successful.”

“I think their review is super interesting,” says Cara Wall-Scheffler at Seattle Pacific University, who has been critical of the hypothesis. But she also points out that endurance running is mentioned in just 2 per cent of all the accounts of hunting the study looked at.
Henry Bunn at the University of Wisconsin-Madison says he remains sceptical of the hypothesis. Bunn thinks the method wouldn’t have worked in the bushlands where humans evolved, where hunters would quickly lose sight of fleeing prey. He also thinks endurance hunters would catch mostly young or old animals, but his team found teeth from butchered animals in their prime at one 2-million-year-old site.
On the basis of similar accounts of hunting, Wall-Scheffler recently argued that women took part in hunts much more often than thought. Morin says there are “copious” examples of women and girls taking part in running races, but he and his colleagues found that only 2 per cent of the accounts of endurance hunting they looked at describe women doing it.

Ramesses III was one of Egypt’s great warrior pharaohs. A temple he built at Medinet Habu, near the Valley of the Kings, highlights why. On its walls, carvings tell the story of a coalition of fighters that swept across the eastern Mediterranean 3200 years ago, destroying cities, states and even whole empires. “No land could stand before their arms,” this account tells us. Eventually, the invaders – known today as the Sea Peoples – attacked Egypt. But Ramesses III succeeded where others had failed and crushed them.
In the 200 years since hieroglyphics were first deciphered, allowing us to read Ramesses III’s extraordinary story, evidence has come to light to corroborate it. We now know of numerous cities and palaces across the eastern Mediterranean that were destroyed around that time, with the Sea Peoples often implicated. So widespread was the devastation that, for one of the only times in history, several complex societies went into a steep decline from which they never recovered. Little wonder, then, that this so-called Late Bronze Age collapse has fascinated scholars for decades. So, too, has the identity of the mysterious sea-faring marauders.

Today, new genetic and archaeological evidence is giving us the firmest picture yet about what really went on at this dramatic time – and who, or what, was responsible. This shows that many of our ideas about the Sea Peoples and the collapse need completely rethinking. It also hints at a surprising idea: the end of civilisation might not always be as disastrous as we think.

A reconstruction of what Shanidar Z might have looked like, by Dutch twins Adrie and Alfons KennisBBC Studios/Jamie Simonds
MEET Shanidar Z, one of the most important Neanderthal discoveries in a generation. Her remains, thought to date back 75,000 years, were fully unearthed five years ago in a re-excavation of a legendary archaeological site, Shanidar cave, in the Kurdistan region of Iraq.

She appears to have been deliberately interred along with a cluster of nine other Neanderthal men, women and children, whose skeletons were uncovered from the 1950s onwards and transformed our… More

An ornament found with the burned remains of royal people at a Maya templeDr Christina T. Halperin
Around 1200 years ago in a Maya city, the bones of several royal people were burned and unceremoniously discarded within the foundations of a new temple. These recently discovered remains may have marked a fiery political transition at a time of upheaval in the Maya world.
“When we first started excavating, we had no idea what this was,” says Christina Halperin at the University of Montreal. She and her colleagues made the discovery in 2022 at the archaeological site of Ucanal, located in present-day Guatemala.
The researchers found the deposit mixed in with rocks beneath a pyramid temple structure. The deposit contained the bones of at least four people, along with thousands of ornamental fragments and beads. The bones of two individuals and many of the ornaments showed evidence of burning at high temperature.Advertisement

It was clear this wasn’t a normal set of remains, says Halperin. But it was the nosepiece and obsidian eye discs of a burial mask that made clear they were royal individuals. She says sifting these clues from the ash “took forever”.
Despite their apparent highborn origins, the royals’ burned remains were not carefully buried but were instead “dumped there”, says Halperin. Radiocarbon dating of the bones and ash also indicated at least one individual had died up to a century before the remains were burned between AD 773 and 881. This suggests the bones were exhumed from a previous burial and then burned.
This timing corresponds with the rise of a new leader at Ucanal named Papmalil, an outsider who came to power amid a wider unravelling of Maya society. Within that context, the researchers think the deposit may be the product of what is known as the “fire-entering rite”, a Maya ritual that dramatically marked the destruction and end of the previous dynasty and the preeminence of the next. “This rite seems to be both an act of veneration, but also an act of destruction,” says Halperin.
Simon Martin at the University of Pennsylvania says the discovery provides vivid physical evidence for the theory that influence from outside cultures contributed to radical shifts in Maya society during this period. “These are the ancestors. These are the forebears,” he says. “To do this kind of thing is really tearing all of that up.”

Researchers exploring the Umm Jirsan lava tube system in Saudi ArabiaPALAEODESERTS Project, CC-BY 4.0 (https://creativecommons​.org/licenses/by/4.0/)
Archaeologists have found evidence of human habitation within lava tubes for the first time, in the deserts of northern Saudi Arabia.
Lava tubes are caves that form during a volcanic eruption. The surface of a river of lava cools and solidifies, while hot molten rock continues to flow beneath it. Eventually, lava drains out of the tube, leaving behind a tunnel.

Mathew Stewart at Griffith University in Brisbane, Australia, and his colleagues excavated a trench inside Umm Jirsan. At 1.5 kilometres in length, it is the biggest lava tube in Saudi Arabia. The researchers discovered animal bones, stone tools and pottery stretching back at least 7000 years and possibly as much as 10,000 years.
Stewart and his team have worked in the region for more than 15 years and have previously found numerous stone structures on the surface, confirming human habitation. However, the desert’s hot, arid climate has caused organic material to break down, making it difficult to date.
On the surface, the landscape is a “hot, dry and flat basalt desert”, says Stewart. “But when you are down in the lava tube, it’s much cooler. It’s very sheltered and it would have been a great place of refuge.”
“It’s transforming our understanding of the prehistory of the Arabian peninsula,” he says.
In parts of the underground network at Umm Jirsan, the researchers also found human bones, but these are thought to have been dragged in by hyenas.
In other lava tubes nearby, Stewart and his colleagues found rock art, including representations of domestic sheep and goats that would have been made by “cultural contemporaries” of the groups using the lava tubes as a refuge, he says.
Mike Morley at Flinders University in Adelaide, Australia, describes the lava tubes as being like “prefabricated activity spaces”.
“As a scientist who works primarily in caves, I am excited that we have another type of cave system being used by past human populations,” says Morley. “These finds represent a treasure trove of archaeological information for Arabia, a massive region that has only recently been investigated systematically for prehistoric archaeology.”
Lava tubes have also been suggested as possible places for humans to shelter on the moon and Mars.
