Una nueva investigación indica que los humanos repoblaron las islas británicas hace unos 15.200 años, casi 500 años antes de lo que se estimaba anteriormente. El regreso coincidió con un fuerte aumento de las temperaturas estivales que transformó el paisaje.

Las personas volvieron a asentarse en Gran Bretaña a medida que la última gran capa de hielo retrocedía, siguiendo a manadas de renos y caballos a través de pastizales que se volvían más cálidos. En aquel momento, Gran Bretaña permanecía conectada con Europa continental, lo que facilitó la migración tanto de humanos como de animales. Esta cronología actualizada proviene de fechas de radiocarbono recalibradas y de un nuevo análisis de sedimentos del lago Llangorse, en el sur de Gales.

DNA study supports human arrival in Australia 60,000 years ago

Scientists have found genetic evidence that modern humans reached New Guinea and Australia around 60,000 years ago, backing the long chronology over more recent estimates. The international team, led by researchers at the University of Huddersfield and the University of Southampton, analyzed nearly 2,500 mitochondrial DNA genomes from Aboriginal Australians, New Guineans, and Southeast Asian populations. Their work suggests early migrants used at least two routes through Southeast Asia.

Ancient DNA uncovers population replacement near Paris around 3000 BC

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.

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.
