Le retour des humains en Grande-Bretagne a eu lieu 500 ans plus tôt après l'ère glaciaire

De nouvelles recherches indiquent que les humains ont repeuplé les îles Britanniques il y a environ 15 200 ans, soit près de 500 ans plus tôt que les estimations précédentes. Ce retour a coïncidé avec une hausse marquée des températures estivales qui a transformé le paysage.

Les populations sont revenues en Grande-Bretagne à mesure que la dernière grande calotte glaciaire se retirait, suivant des troupeaux de rennes et de chevaux à travers des prairies qui se réchauffaient. À cette époque, la Grande-Bretagne était encore reliée à l'Europe continentale, ce qui a facilité la migration des humains comme des animaux. Cette chronologie actualisée provient de datations au radiocarbone recalibrées et d'une nouvelle analyse des sédiments du lac Llangorse, dans le sud du pays de Galles.

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

22 avril 2026 Rapporté par l'IA

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.

Drought linked to extinction of homo floresiensis 61,000 years ago

A prolonged drought around 61,000 years ago may have driven the extinction of Homo floresiensis, the small-bodied human species known as hobbits, on the Indonesian island of Flores. Researchers analyzed cave stalagmites and fossil teeth to reconstruct climate conditions that aligned with the species' disappearance from Liang Bua cave. The drying trend also affected their prey, pygmy elephants, exacerbating food and water shortages.

Ancient Antarctic ice reveals modest greenhouse gas changes over 3 million years

25 avril 2026 Rapporté par l'IA

Scientists analyzing ancient ice from Antarctica have found that ocean temperatures dropped by 2 to 2.5 degrees Celsius over the past 3 million years, while carbon dioxide and methane levels changed only modestly. The studies, led by researchers from Oregon State University and others, suggest factors beyond greenhouse gases drove much of Earth's long-term cooling. The findings come from ice cores at Allan Hills in East Antarctica.
