  • Neanderthal and Denisovan blood groups deciphered
    on July 28, 2021 at 6:03 pm

    The blood groups of three Neanderthals one Denisovan have been determined by a team including a palaeoanthropologist, population geneticists, and haematologists. Their research provides new data for understanding the origins, history, and health of these extinct hominin lineages.

  • Human environmental genome recovered in the absence of skeletal remains
    on July 12, 2021 at 4:21 pm

    Ancient sediments from caves have already proven to preserve DNA for thousands of years. The amount of recovered sequences from environmental sediments, however, is generally low, which complicates analyses. A study has now successfully retrieved three mammalian environmental genomes from a single soil sample of 25,000 years BP obtained from the cave of Satsurblia in the Caucasus (Georgia).

  • Neanderthal artists? Bones decorated over 50,000 years ago
    on July 6, 2021 at 3:53 pm

    Since the discovery of the first fossil remains, the image of the Neanderthal has been one of a primitive hominin. People have known for a long time that Neanderthals were able to fashion tools and weapons. But could they also make jewellery or even art? Researchers analyzed a new find from the Unicorn Cave in the Harz Mountains in Germany and conclude that Neanderthals had remarkable cognitive abilities.

  • Where are the Foreigners of the First International Age?
    on June 30, 2021 at 9:36 pm

  • Bronze Age: how the market began
    on June 29, 2021 at 11:17 pm

    Knowing the weight of a commodity provides a way to value goods in the marketplace. But did a self-regulating market even exist in the Bronze Age? And what can weight systems tell us? Researchers investigated the dissemination of weight systems throughout Western Eurasia. Their simulation indicates that the interaction of merchants, even without intervention from institutions, is likely to explain the spread of Bronze Age technology to weigh goods.

  • This 5,000-year-old man had the earliest known strain of plague
    on June 29, 2021 at 8:13 pm

    The oldest strain of Yersinia pestis -- the bacteria behind the plague that caused the Black Death, which may have killed as much as half of Europe's population in the 1300s -- has been found in the remains of a 5,000-year-old hunter-gatherer. A genetic analysis reveals that this ancient strain was likely less contagious and not as deadly as its medieval version.

  • How humans brought change to a tropical paradise
    on June 29, 2021 at 2:12 pm

    After centuries of human impact on the world's ecosystems, a new study details an example of how a common native bee species has flourished since the very first land clearances by humans on Fiji.

  • A new type of Homo unknown to science
    on June 24, 2021 at 6:15 pm

    The bones of an early human, unknown to science, who lived in the Levant at least until 130,000 years ago, were discovered in excavations at the Nesher Ramla site, near the city of Ramla. Recognizing similarity to other archaic Homo specimens from 400,000 years ago, found in Israel and Eurasia, the researchers reached the conclusion that the Nesher Ramla fossils represent a unique Middle Pleistocene population, now identified for the first time.

  • Being Anglo-Saxon was a matter of language and culture, not genetics
    on June 23, 2021 at 6:49 pm

    Archaeologists have provided important new evidence to answer the question 'who exactly were the Anglo-Saxons?' New findings based on studying skeletal remains clearly indicates the Anglo-Saxons were a melting pot of people from both migrant and local cultural groups and not one homogenous group from Western Europe.

  • Pleistocene sediment DNA from Denisova Cave
    on June 23, 2021 at 3:38 pm

    Researchers have analyzed DNA from 728 sediment samples from Denisova Cave. Their study provides unprecedented detail about the occupation of the site by both archaic and modern humans over 300,000 years. The researchers detected the DNA of Neandertals and Denisovans, the two forms of archaic hominins who inhabited the cave, and the DNA of modern humans who appeared around the time of the emergence of an archaeological culture called the Initial Upper Paleolithic around 45,000 years ago.

  • Bronze Age Scandinavia's trading networks for copper
    on June 17, 2021 at 3:55 pm

    Five hundred years after the full implementation of copper technology in Scandinavia, the trade that brought the much needed copper to Denmark and southern Sweden also expanded across the Alps. At this time, Bronze Age Scandinavians already traded frequently in central Europe and across the North Sea.

  • Light in darkness: An experimental look at Paleolithic cave lighting
    on June 16, 2021 at 6:30 pm

    A recreation of three common types of Paleolithic lighting systems (torches, grease lamps, and fireplaces) illuminates how Paleolithic cave dwellers might have traveled, lived, and created in the depths of their caves, according to a new study.

  • Ten years of ancient genome analysis has taught scientists 'what it means to be human'
    on June 16, 2021 at 3:38 pm

    A ball of 4,000-year-old hair frozen in time tangled around a whalebone comb led to the first ever reconstruction of an ancient human genome a decade ago. The hair, which was preserved in arctic permafrost in Greenland, was collected in the 1980s. It wasn't until 2010 that evolutionary biologists were able to use pioneering shotgun DNA sequencing to reconstruct the genetic history of the hair. It sparked a 'decade of discovery.'

  • Fashion for pointy shoes unleashed plague of bunions in medieval Britain
    on June 11, 2021 at 12:56 pm

    Researchers analysing skeletal remains in the city of Cambridge find a dramatic increase in 'hallux valgus' around the time that pointed shoes became de rigueur in the 1300s. They also uncover a link between this minor deformity and increased risk of fractures.

  • Researchers link ancient wooden structure to water ritual
    on June 10, 2021 at 1:11 pm

    A team used dendrochronology and a form of radiocarbon dating called 'wiggle-matching' to pinpoint, with 95% probability, the years in which an ancient wooden structure's two main components were created: a lower tank in 1444 B.C., and an upper tank in 1432 B.C.

  • Entire genome from Pestera Muierii 1 sequenced
    on May 20, 2021 at 5:37 pm

    Researchers have successfully sequenced the entire genome from the skull of Pestera Muierii 1, a woman who lived in today's Romania 35,000 years ago. Her high genetic diversity shows that the out of Africa migration was not the great bottleneck in human development but rather this occurred during and after the most recent Ice Age.

  • The Aqueduct of Constantinople: Managing the longest water channel of the ancient world
    on May 11, 2021 at 12:11 pm

    Aqueducts are very impressive examples of the art of construction in the Roman Empire. Even today, they still provide us with new insights into aesthetic, practical, and technical aspects of construction and use. Scientists investigated the longest aqueduct of the time, the 426-kilometer-long Aqueduct of Valens supplying Constantinople, and revealed new insights into how this structure was maintained back in time.
