Ancient DNA reveals genetic replacement despite language continuity in the South Pacific

The study, published in Nature Ecology & Evolution and led by a multidisciplinary research team at the Max Planck Institute for the Science of Human History (MPI-SHH) together with researchers in France, Australia, New Zealand, Germany and Vanuatu, reveals that migrations of people from the Bismarck Archipelago in Oceania to the previously settled islands of the Pacific began as early as 2,500 years ago, much earlier than previously thought.

The Remote Oceanian island nation of Vanuatu is the gateway to the rest of the Pacific and understanding its demographic history is critical to uncovering that of the wider region. The earliest inhabitants of Vanuatu, arriving about 3,000 years ago, were the Lapita peoples who spoke a form of Austronesian language and who had largely East Asian genetic ancestry. But Vanuatu’s contemporary population has largely Near Oceanian heritage, showing that over time the genetic ancestry of the early inhabitants was mostly replaced by that of Bismarck Archipelago migrants, who began arriving very soon after initial settlement. Yet the original Austronesian language persisted and over 120 descendant languages continue to be spoken today, making Vanuatu the per capita most linguistically diverse place on Earth. Vanuatu therefore presents an unprecedented case, where a population’s genetic ancestry but not its languages were replaced. Read more.

Medieval villagers mutilated the dead to stop them rising, study finds

A study by archaeologists has revealed certain people in medieval Yorkshire were so afraid of the dead they chopped, smashed and burned their skeletons to make sure they stayed in their graves.

The research published by Historic England and the University of Southampton may represent the first scientific evidence in England of attempts to prevent the dead from walking and harming the living – still common in folklore in many parts of the world.

The archaeologists who studied a collection of human bones – including the remains of adults, teenagers and children excavated more than half a century ago, and dated back to the period between the 11th and 14th century – rejected gruesome possibilities including cannibalism in times of famine, or the massacre of outsiders. The cut marks were in the wrong place for butchery, and isotope analysis of the teeth showed that the people came from the same area as the villagers of Wharram Percy in North Yorkshire – a once flourishing village which had been completely deserted by the early 16th century.
