    The archaeologist fighting claims about an advanced lost civilisation

    Paul Ryding
    Archaeological research has helped us understand the complicated story of our species’ past, from the earliest hominins to the dawn of civilisation and beyond. But some people are convinced that it has overlooked an important chapter. They believe there was an advanced global civilisation some 20,000 years ago during the last glacial maximum, often referred to as the ice age – but that it was mysteriously destroyed, with its impressive settlements and monuments drowned by rising seas.
    Flint Dibble, an archaeologist at Cardiff University in the UK, is doing all he can to make it clear that such ideas aren’t supported by the evidence. Earlier this year, he appeared on The Joe Rogan Experience podcast to take part in a high-profile debate with Graham Hancock, a writer who has spent years arguing for the existence of this forgotten society and who discusses the idea in his Netflix show, Ancient Apocalypse.

    Dibble spoke to New Scientist about the reasons for the enduring appeal of mythical lost civilisations, why belief in them can be so harmful, and how to persuade people to reject the ideas promoted by Hancock and others through the use of “truth sandwiches”.
    Colin Barras: Why do you think the myth of an advanced lost civilisation generates so much interest?
    Flint Dibble: That’s a tough one. You have to appreciate that Graham Hancock’s idea isn’t new: it stems directly out of … More

    One of the most important factors in the evolution of humans and other hominins is their relationship with food, and how it has changed over the millennia.
    There are some foods that we can barely imagine living without, but that are quite recent additions to our diet. Take wheat, which we use to make bread, pasta, cake and… More

    Read an extract from Rachel Kushner’s Creation Lake

    A reconstruction of male and female Neanderthals based on the La Chapelle-aux-Saints fossilsS. ENTRESSANGLE/E. DAYNES/SCIENCE PHOTO LIBRARY

    NEANDERTHALS WERE PRONE TO DEPRESSION, he said.
    He said they were prone to addiction, too, and especially smoking.Advertisement
    Although it was likely, he said, that these noble and mysterious Thals (as he sometimes referred to the Neanderthals) extracted nicotine from the tobacco plant by a cruder method, such as by chewing its leaves, before that critical point of inflection in the history of the world: when the first man touched the first tobacco leaf to the first fire.
    Reading this part of Bruno’s email, scanning from “man” to “touch” to “leaf ” to “fire,” I pictured a 1950s greaser in a white T-shirt and a black leather jacket as he touches a lit match to the tip of his Camel cigarette, and inhales. The greaser leans against a wall—because that is what greasers do, they lean and loiter—and then he exhales.
    Bruno Lacombe told Pascal, in these emails I was secretly reading, that the Neanderthals had very large brains. Or at least their skulls were very large, and we can safely infer that their skulls were likely filled, Bruno said, with brains.

    He talked about the impressive size of a Thal’s braincase using modern metaphors, comparing them to motorcycle engines, which were also measured, he noted, for their displacement. Of all the humanlike species who stood up on two feet, who roamed the earth for the last one million years, Bruno said that the Neanderthal’s braincase was way out in front, at a whopping 1,800 cubic centimeters.
    I pictured a king of the road, way out in front.
    I saw his leather vest, his big gut, legs extended, engineers’ boots resting on roomy and chromed forward-mounted foot pegs. His chopper is fitted with ape hangers that he can barely reach, and which he pretends are not making his arms tired, are not causing terrible shooting pains to his lumbar region.
    We know from their skulls, Bruno said, that Neanderthals had enormous faces.
    I pictured Joan Crawford, that scale of face: dramatic, brutal, compelling.
    And thereafter, in the natural history museum in my mind, the one I was creating as I read Bruno’s emails, its dioramas populated by figures in loincloths, with yellow teeth and matted hair, all these ancient people Bruno described—the men too—they all had Joan Crawford’s face.
    They had her fair skin and her flaming red hair. A propensity for red hair, Bruno said, had been identified as a genetic trait of the Thal, as scientific advancements in gene mapping were made. And beyond such work, such proof, Bruno said, we might employ our natural intuition to suppose that like typical redheads, the Neanderthals’ emotions were strong and acute, spanning the heights and depths.
    A few more things, Bruno wrote to Pascal, that we now know about Neanderthals: They were good at math. They did not enjoy crowds. They had strong stomachs and were not especially prone to ulcers, but their diet of constant barbecue did its damage as it would to anyone’s gut. They were extra vulnerable to tooth decay and gum disease. And they had overdeveloped jaws, wonderfully capable of chewing gristle and cartilage but inefficient for softer fare, a jaw that was overkill. Bruno described the jaw of the Neanderthal as a feature of pathos for its overdevelopment, the burden of a square jaw. He talked about sunk costs, as if the body were a capital investment, a fixed investment, the parts of the body like machines bolted to a factory floor, equipment that had been purchased and could not be resold. The Neanderthal jaw was a sunk cost.
    Still, the Thal’s heavy bones and sturdy, heat-conserving build were to be admired, Bruno said. Especially compared to the breadstick limbs of modern man, Homo sapiens sapiens. (Bruno did not say “breadstick,” but since I was translating, as he was writing these emails in French, I drew from the full breadth of English, a wildly superior language and my native tongue.)
    The Thals survived cold very well, he said, if not the eons, or so the story about them goes—a story that we must complicate, he said, if we are to know the truth about the ancient past, if we are to glimpse the truth about this world, now, and how to live in it, how to occupy the present, and where to go tomorrow.
    ——
    My own tomorrow was thoroughly planned out. I would be meeting Pascal Balmy, leader of Le Moulin, to whom these emails from Bruno Lacombe were written. And I didn’t need the Neanderthals’ help on where to go: Pascal Balmy said to go to the Café de la Route on the main square in the little village of Vantôme at one p.m., and that was where I would be.

    Runaway stars could influence the cosmos far past their home galaxies

    Dozens of fugitive stars were caught fleeing a dense star cluster in a satellite galaxy of the Milky Way. The swarm of speeding stars could mean that such runaways had a bigger influence on cosmic evolution than previously thought, astronomers report October 9 in Nature.

    Massive stars are born in young clusters, packed so close together that they can jostle each other out of place. Sometimes, encounters between pairs of massive stars or neighboring supernova explosions can send a star zipping out of the cluster altogether, to seek its fortune in the wider galaxy and beyond.

    A cave in France is revealing how the Neanderthals died out

    Simon Prades
    Around 41,000 years ago, the very last Neanderthal took their final breath. At that moment, we became the only remaining hominins, the sole survivors of the once diverse family of bipedal apes.
    We will never know exactly when or where this momentous event took place, but we do know the Neanderthals died out suspiciously close to the time when modern humans arrived in their territory. Exactly why they vanished has long been hotly debated, but astonishing revelations from the genomes of the last Neanderthals and hidden in a remarkable cave in France are now painting a detailed picture of these first encounters – and what might have happened next.

    “This is a major turning point in our understanding of Neanderthals and their extinction process,” says Ludovic Slimak at the Centre for Anthropobiology and Genomics of Toulouse, France.
    Our species, Homo sapiens, and Neanderthals share a common ancestor, but Neanderthals split from our lineage at least 400,000 years ago, evolving in Eurasia, from the Mediterranean to Siberia. Our species is younger, first appearing in Africa some 300,000 years ago and evolving into hominins that were anatomically much like us by at least 195,000 years ago. Modern humans left the continent in waves from around 170,000 years ago, and were thought to have reached western Europe roughly 43,000 years ago, when – according to the… More

    Barnard’s star has at least one planet orbiting it after all

    A red dwarf star known as Barnard’s star, which lies a mere six light-years from our solar system, has at least one — and possibly a handful — of small rocky planets orbiting it, a new study suggests.

    Barnard’s star, which is about one-sixth the mass of our sun, is the closest individual star to our solar system. Only the three stars in the Alpha Centauri system are closer. Due to its proximity to Earth, Barnard’s star has long been a target of astronomers looking for exoplanets (SN: 12/1/73, SN: 12/7/23). More

    Ancient DNA tells story of toddler who lived in Italy 17,000 years ago

    The skeleton of an infant uncovered at Grotta delle Mura in Apulia, ItalyMauro Calattin
    Ancient DNA analysis has revealed a detailed picture of the life of a toddler who died in southern Italy 17,000 years ago, possibly due to a congenital heart condition.
    In 1998, researchers discovered the skeletal remains of a child carefully laid under rock slabs in the floor of the Grotta delle Mura cavern in Apulia, southern Italy. It was the only burial in the cave, which also included signs of daily life and human occupation, says Alessandra Modi at the University of Florence… More

    Betelgeuse has a tiny companion star hidden in plain sight

    Betelgeuse, Betelgeuse! The red supergiant that marks Orion’s left shoulder may have a tiny, unseen companion.

    Two independent studies found evidence of a star about the same mass as the sun, orbiting Betelgeuse about once every 2,100 days.

    “It was very surprising,” says astrophysicist Morgan MacLeod of the Harvard & Smithsonian Center for Astrophysics in Cambridge, Mass. If the star is real, “it’s kind of hidden right there in plain sight.”

    MacLeod and colleagues linked a six-year cycle of Betelgeuse brightening and dimming to a companion star tweaking its orbit, in a paper submitted to arXiv.org September 17. MacLeod examined global, historical measurements dating back to 1896. More
