  • Unique diversity of the genetic history of the Iberian Peninsula revealed by dual studies
    on March 14, 2019 at 7:15 pm

    Researchers have analyzed ancient DNA from almost 300 individuals from the Iberian Peninsula, spanning more than 12,000 years. The first study looked at hunter-gatherers and early farmers living in Iberia between 13,000 and 6,000 years ago. The second looked at individuals from the region over the last 8000 years. Together, the two papers greatly increase our knowledge about the population history of this unique region. […]

  • Strontium isotope maps are disturbed by agricultural lime
    on March 13, 2019 at 6:32 pm

    Strontium isotopes are frequently used in archaeological studies to establish the provenance and migration history of prehistoric people and artifacts. Many of these studies may be based on incorrect data. A new study shows that agricultural lime can alter the composition of strontium isotopes dramatically, so that the modern isotopic signature of an area may be very different from the prehistoric signature. […]

  • Prehistoric Britons rack up food miles for feasts near Stonehenge
    on March 13, 2019 at 6:05 pm

    Archaeologists have unearthed evidence of the earliest large-scale celebrations in Britain - with people and animals traveling hundreds of miles for prehistoric feasting rituals. The study is the most comprehensive to date and examined the bones of 131 pigs, the prime feasting animals, from four Late Neolithic complexes. Serving the world-famous monuments of Stonehenge and Avebury, the four sites hosted the very first pan-British events. […]

  • From Stone Age chips to microchips: How tiny tools may have made us human
    on March 12, 2019 at 4:37 pm

    on March 5, 2019 at 8:36 pm

    For thousands of years brewers made beer using specialized strains of the budding yeast Saccharomyces cerevisiae. A new study shows that modern brewing strains were derived from a mixture of European grape wine and Asian rice wine strains. This finding points to the emergence of beer yeast from a historical East-West transfer of fermentation technology. […]

  • Biodiversity on land is not higher today than in the past, study shows
    on February 18, 2019 at 5:31 pm

    The rich levels of biodiversity on land seen across the globe today are not a recent phenomenon: diversity on land has been similar for at least the last 60 million years, since soon after the extinction of the dinosaurs. […]

  • Indigenous hunters have positive impacts on food webs in desert Australia
    on February 17, 2019 at 7:25 pm

    Australia has the highest rate of mammal extinction in the world. Resettlement of indigenous communities resulted in the spread of invasive species, the absence of human-set fires, and a general cascade in the interconnected food web that led to the largest mammalian extinction event ever recorded. In this case, the absence of direct human activity on the landscape may be the cause of the extinctions, according to an anthropologist. […]

  • New dinosaur with heart-shaped tail provides evolutionary clues for African continent
    on February 13, 2019 at 7:27 pm

  • Earliest known seed-eating perching bird discovered in Fossil Lake, Wyoming
    on February 7, 2019 at 4:50 pm

    The 'perching birds,' or passerines, are the most common birds in the world today -- they include sparrows, robins, and finches. They used to be very rare. Scientists have just discovered some of the earliest relatives of the passerines, including a 52-million-year-old fossil with a thick, curved beak for eating seeds. […]

  • The Caucasus: Complex interplay of genes and cultures
    on February 4, 2019 at 1:59 pm

    In the Bronze Age, the Caucasus Mountains region was a cultural and genetic contact zone. Here, cultures that originated in Mesopotamia interacted with local hunter-gatherers, Anatolian farmers, and steppe populations from just north of the mountain ranges. Here, pastoralism was developed and technologies such as the wheeled wagon and advanced metal weapons were spread to neighbouring cultures. A new study, examines new genetic evidence in concert with archaeological evidence to paint a more […]

  • An ancient strain of plague may have led to the decline of Neolithic Europeans
    on December 6, 2018 at 5:00 pm

    Researchers have identified a new strain of Yersinia pestis, the bacteria that causes plague, in DNA extracted from 5,000-year-old human remains. Their analyses suggest that this strain is the closest ever identified to the genetic origin of plague. Their work also suggests that plague may have been spread among Neolithic European settlements by traders, contributing to their decline. […]
