  • New data platform illuminates history of humans' environmental impact
    on May 13, 2019 at 3:22 pm

    Animal remains found at archaeological sites tell the millennia-long story of how humans have hunted, domesticated and transported wildlife, altered landscapes and responded to environmental changes such as shifting temperatures and sea levels. Now, that story is available digitally through a new open-access data platform known as ZooArchNet, which links records of animals across biological and archaeological databases. […]

  • Uncovering a 5000-year-old family tragedy

  • Ancient DNA suggests that some Northern Europeans got their languages from Siberia
    on May 9, 2019 at 6:26 pm

    Most Europeans descend from a combination of European hunter-gatherers, Anatolian early farmers, and Steppe herders. But only European speakers of Uralic languages like Estonian and Finnish also have DNA from ancient Siberians. Now, with the help of ancient DNA samples, researchers suggest that these languages may have arrived from Siberia by the beginning of the Iron Age, about 2,500 years ago, rather than evolving in Northern Europe. […]

  • First hominins on the Tibetan Plateau were Denisovans
    on May 1, 2019 at 5:14 pm

    So far Denisovans were only known from a small collection of fossil fragments from Denisova Cave in Siberia. A research team now describes a 160,000-year-old hominin mandible from Xiahe in China. Using ancient protein analysis the researchers found that the mandible's owner belonged to a population that was closely related to the Denisovans from Siberia. This population occupied the Tibetan Plateau in the Middle Pleistocene and was adapted to this low-oxygen environment long before Homo sapiens […]

  • Human ancestors were 'grounded,' new analysis shows
    on April 30, 2019 at 2:34 pm

  • Holy Pleistocene Batman, the answer's in the cave
    on April 25, 2019 at 11:36 am

    Examining a 3-meter stack of bat feces has shed light on the landscape of the ancient continent of Sundaland. The research could help explain the biodiversity of present-day Borneo, Sumatra, and Java. It could also add to our understanding of how people moved through the region. […]

  • Better labor practices could improve archaeological output
    on April 22, 2019 at 12:22 pm

    Archaeological excavation has, historically, operated in a very hierarchical structure, according to archaeologist. The history of the enterprise is deeply entangled with Western colonial and imperial pursuits, she says. Excavations have been, and often still are, led by foreigners from the West, while dependent on the labor of scores of people from the local community to perform the manual labor of the dig. […]

  • A history of the Crusades, as told by crusaders' DNA
    on April 18, 2019 at 5:14 pm

    History can tell us a lot about the Crusades, the series of religious wars fought between 1095 and 1291, in which Christian invaders tried to claim the Near East. But the DNA of nine 13th century Crusaders buried in a pit in Lebanon shows that there's more to learn about who the Crusaders were and their interactions with the populations they encountered. […]

  • Ancient 'Texas Serengeti' had elephant-like animals, rhinos, alligators and more
    on April 11, 2019 at 2:18 pm

    During the Great Depression, Texans were put to work as fossil hunters. The workers retrieved tens of thousands of specimens that have been studied in small bits and pieces while stored in the state collections of The University of Texas at Austin for the past 80 years. Now, decades after they were first collected, a researcher has studied and identified an extensive collection of fossils from dig sites near Beeville, Texas, and found that the fauna make up a veritable 'Texas Serengeti.'

  • Digging ancient signals out of modern human genomes
    on April 5, 2019 at 10:39 pm

    Trying to find ancient DNA, let alone prove that the ancient DNA is ancestral to a population living today, is extremely challenging. A new study adds to this understanding by reconstructing artificial genomes with the analyses of the genome of 565 contemporary South Asian individuals to extract ancient signals that recapitulate the long history of human migration and admixture in the region. […]
