新しい研究により、人類がイギリス諸島に再移住したのは約1万5200年前であり、従来の推定よりも約500年早かったことが示唆された。この再移住は、夏の気温が急上昇し、景観が一変した時期と重なっている。
最後の主要な氷床が後退する中、人々は温暖化する草原を移動するトナカイや馬の群れを追いかけ、英国へと戻った。当時、英国は欧州大陸と地続きであったため、人間と動物の双方にとって移動が容易であった。今回の修正された年表は、放射性炭素年代測定の再調整と、南ウェールズのランゴース湖から採取された堆積物の新たな分析結果に基づいている。
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.

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.
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.

A new study has found evidence that early human ancestors carried fire into Wonderwerk Cave in South Africa as early as 1.79 million years ago. Researchers identified burned bones deep inside the cave using a new detection method.
