    Ancient Egyptians shaped sheep’s horns – and we don’t know why

    Sheep skulls modified by ancient Egyptians so that their horns grew upward instead of outwardB. De Cupere
    Sheep with deformed horns are among the more mysterious animal remains discovered at an ancient Egyptian burial site dating back to around 3700 BC. They also represent the oldest physical evidence of humans modifying the horns of livestock.
    “The sheep were deliberately made ‘special’ by castration,” says Wim Van Neer at the Royal Belgian Institute of Natural Sciences. “In addition, their horns were directed upward, and in one case, the horns were removed.” More

    Before the Stone Age: Were the first tools made from plants not rocks?

    Bitter/iStock
    There are few things more irritating in everyday life than getting something stuck between your teeth. Thankfully, we can reach for a toothpick – and it seems our ancient ancestors did the same. In fact, a fragment of a 1.2-million-year-old toothpick is perhaps the earliest direct evidence we have of hominins using plants as tools.
    Our ancient ancestors probably made frequent use of implements made from plants. But finding evidence of this is extremely tough because botanical materials are so quick to rot away. This means the archaeological record of human tool use is deeply skewed towards the much hardier stone.
    All this suggests that the origins of human technology could have been profoundly misunderstood.

    Stone Age
    The conventional view is it all started with the first stone tools and the dawn of the Stone Age over 3 million years ago. But what if, even before that, there was a botanical age, one based on woodworking and weaving of plant materials? For some researchers, it is absurd not to think that plants would be part of the story. “Perishable material culture is an essential element in our evolutionary past,” says Linda Hurcombe at the University of Exeter in the UK.
    Now, we are finally getting a clearer view of this lost age. New techniques are making it possible to find traces of plant-based tools that would otherwise have been missed. And by studying the way modern primates use plants,… More

    Ancient Mesopotamian clay seals offer clues to the origin of writing

    The world’s oldest known writing system may have had its origins in the imagery on decorated cylinders used to denote ownership. Some of the symbols on these cylinder seals correspond to those used in proto-cuneiform, a form of proto-writing used in Mesopotamia.
    The finding indicates that the invention of writing in Mesopotamia was a decentralised process, in which many people across a wide area contributed to the set of symbols used.

    “There’s been this longstanding reconstruction of how writing appeared in Mesopotamia, which is arguably the earliest invention of writing in the world,” says Silvia Ferrara at the University of Bologna in Italy. “We’re retracing the trajectory in a way that’s more, I would say, colourful, less straitjacketed.”
    The oldest known true writing system is cuneiform, invented around 3200 BC in Mesopotamia. It was preceded by a simpler system called proto-cuneiform, which was in use from 3350 to 3000 BC.
    Proto-writing like proto-cuneiform is distinguished by a lack of grammatical rules, which means it cannot convey complex meanings, says Amy Richardson at the University of Reading in the UK, who wasn’t involved in the research. For instance, proto-cuneiform can be used to label something as “seven bushels of wheat”, but only true writing like cuneiform can say “seven bushels of wheat will be delivered to you”.
    The origins of proto-cuneiform have often been traced to clay tokens. These came in a variety of shapes, such as discs and spheres, and were often engraved with patterns. The tokens could be pressed into wet clay, creating a symbol. Some of the symbols on the tokens are similar to those found in proto-cuneiform, as documented by Denise Schmandt-Besserat at the University of Texas at Austin in her two-volume book Before Writing in 1992.
    There is some evidence for a role of tokens in the origin of proto-cuneiform, says Ferrara. “But you cannot explain all the signs.”
    Ferrara and her colleagues Kathryn Kelley and Mattia Cartolano, also at the University of Bologna, have instead explored another source of symbols: cylinder seals. These cylindrical objects have patterns and images embossed on them, and leave a rectangular collection of symbols when rolled over sheets of wet clay. The symbols often referred to goods being transported, or to administrators involved in transactions, says Cartolano.

    The team examined cylinder seals from a wide area of south-west Asia, including Mesopotamia, that dated to 4400 to 3400 BC. They found several symbols that corresponded to proto-cuneiform symbols.
    “One of the clearest examples that we found is the use of the images of fringed cloth and vessel in a net,” says Cartolano. These have well-understood meanings: they refer to the transport of goods. And they are found both on cylinder seals and proto-cuneiform tablets.
    The idea that the symbols on cylinder seals led to some of the symbols in proto-cuneiform was previously suggested by Holly Pittman at the University of Pennsylvania in Philadelphia in a 1994 book chapter and developed in later publications. “I am gratified that, 30 years after I first proposed the fundamental role of seal imagery in the origins of proto-cuneiform script, that a new generation of scholars have taken up my idea and, with their expertise in cuneiform script, have put details to my argument,” says Pittman. She adds that in the 1990s her idea was dismissed “without serious consideration”.

    “I find it to be very convincing,” says Richardson. “There does seem to be a really neat correlation in the particular examples that they’re illustrating in this article.” Her own research has found that cylinder seals were also used to record interactions between cities.
    This doesn’t mean that tokens didn’t play a role. “I think there’s still some strong arguments to make that those tokens really are part of the foundation of abstraction,” says Richardson. In particular, they seem to have been important for the development of counting systems.
    If proto-cuneiform really did arise in this hodge-podge way, drawn from tokens, cylinder seals and possibly other sources, it may tell us something about who was inventing it, says Ferrara. “There is evidence for making a claim that the invention of writing in Mesopotamia was, in fact, much more decentralised than we think,” she says. While powerful people in the major city of Uruk no doubt played a role, perhaps so did other administrators and tradespeople scattered over the region. “I think there’s evidence for having a more widespread… and more distributed prompt to writing,” she says.
    Writing was first used for administration, not for storytelling. “Those first written records tend to be about trying to organise materials, goods, people, things,” says Richardson. “It’s very much about trying to find ways of creating a social system.”

    A zombie star’s spiky filaments shed light on a 12th century supernova

    Some 6,500 light-years from Earth lurks a zombie star cloaked in long tendrils of hot sulfur.

    Nobody knows how those tendrils formed. But astronomers now know where they’re going. New observations, reported in the Nov. 1 Astrophysical Journal Letters, capture the 3-D structure and motion of debris left in the wake of a supernova that was seen to detonate almost 900 years ago.

    “It’s a piece of the puzzle towards understanding this very bizarre [supernova] remnant,” says astronomer Tim Cunningham of the Harvard & Smithsonian Center for Astrophysics in Cambridge, Mass. More

    Using AI, historians track how astronomy ideas spread in the 16th century

    Historians working with an artificial intelligence assistant have begun tracking the spread of astronomical thinking across Europe in the early 1500s.

    The analysis contributes to challenging the “lone genius” idea of scientific revolutions. Instead, it shows that knowledge about the positions of the stars was widespread and used in a variety of disciplines, researchers report October 23 in Science Advances.

    “We can see here the first formation of a proto-international scientific community,” says computational historian Matteo Valleriani of the Max Planck Institute for the History of Science in Berlin. More

    DNA helps match ‘Well Man’ skeleton to 800-year-old Norwegian saga

    The complete skeletal remains of the “Well Man”Age Hojem, NTNU University Museum
    A Norwegian saga written more than 800 years ago describes how a dead man was thrown into a castle well – and now, researchers believe they have identified the remains of this man.
    The Sverris saga is an 182-verse Old Norse text that records the exploits of King Sverre Sigurdsson, who rose to power in the second half of the 12th century AD. One part says that a rival clan who attacked Sverresborg castle, near Trondheim, Norway, “took a dead man and cast him unto the well, and then filled it up with stones”.

    The well was inside the castle’s ramparts and was the community’s only permanent water source. It has been speculated that the man thrown into the well in the saga may have had a disease and putting him there was an early act of biological warfare.
    In 1938, a medieval well in the ruins of Sverresborg castle was partly drained and a skeleton was found beneath rubble and boulders at the bottom. While it was widely believed that the skeleton, referred to as Well Man, was the remains of the individual mentioned in the saga, it wasn’t possible to confirm this at the time.
    Now, Anna Petersén at the Norwegian Institute of Cultural Heritage Research in Oslo and her colleagues have used radiocarbon dating and DNA analysis of a tooth from the body to show that the date range the man was alive is consistent with the raid on the castle. While not definitive proof that the man was the one mentioned in the saga, the “circumstantial evidence is consistent with this conclusion”, says Perersén.
    The Well Man skeleton was discovered in 1938Riksantikvaren (The Norwegian Directorate for Cultural Heritage)
    What is more, the team has been able to add to the story. “The research we have done has shown many details concerning both the event and the man that the saga episode doesn’t mention,” says Petersén.
    For example, the DNA suggests he most likely had blue eyes and blond or light-brown hair. The researchers also believe his ancestors were from what is now Vest-Agder, the southernmost Norwegian county, based on comparisons with the DNA of modern and ancient Norwegians.
    One thing they couldn’t find was any evidence that the man was thrown into the well because he had a disease or to render the drinking water unusable, but they also found no evidence against it, leaving the question unanswered.
    Michael Martin at the Norwegian University of Science and Technology in Trondheim says the team’s approach of matching historical documents with DNA evidence could also be applied to construct family trees of long-dead royal families or to “physically describe and sketch out the life stories, such as movement between geographic regions, of the otherwise anonymous people whose remains are recovered from archaeological excavations”.

    “This is, to my knowledge, the oldest case where genomic information has been recovered from a specific character, or even a specific person, mentioned in an ancient text,” says Martin.
    He says by generating genomic information from ancient skeletal remains, we can provide new details about a person. “These details are not in the original text, thus the genetic data enriches the story and provides a way to separate fact from fiction,” says Martin.
