Une analyse génétique de plus d'un millier de génomes britanniques anciens montre que la conquête romaine a laissé peu de traces sur l'ascendance de l'île, malgré d'importants changements culturels.

Des chercheurs du Francis Crick Institute ont examiné les génomes de 1 039 individus inhumés en Grande-Bretagne, de l'âge du bronze en 2550 av. J.-C. jusqu'en 1150 apr. J.-C. L'étude a révélé que la plupart des personnes vivant sous la domination romaine, entre 43 et 410 apr. J.-C., tiraient l'intégralité de leur ascendance de la Grande-Bretagne de l'âge du fer, seuls 20 % d'entre eux présentant un apport génétique extérieur détectable.

Genetic analysis of remains from a megalithic tomb near Bury, 50 kilometers north of Paris, reveals a complete population turnover around 3000 BC. The earlier group shared genetics with northern European farmers, while newcomers arrived from southern France and the Iberian Peninsula. Researchers link the shift to disease, environmental stress, and social changes.

Bronze Age Britons used bone tools for copper mining

A new study shows that people in Bronze Age Britain continued to rely on animal bone tools for copper extraction at the Great Orme mine in North Wales, even after metal tools became available. Researchers examined 150 bone artefacts and found they were shaped for specific tasks like splitting rock and scraping ore. The practice lasted at least nine centuries from 3700 to 2800 years ago.

Historians challenge drought link to Roman Britain rebellion

Researchers are debating whether droughts triggered unrest in late Roman Britain during the so-called Barbarian Conspiracy of 367 AD. A study using tree ring data linked severe summer droughts in 364-366 to poor harvests and rebellion, but historians say the historical sources have been misinterpreted. The dispute underscores challenges in combining climate data with historical records.
