When and where the earliest modern human populations migrated and settled in East Asia are relatively well known. However, how these populations moved between islands on treacherous stretches of sea is still shrouded in mystery. In two new papers, researchers from Japan and Taiwan led by Professor Yousuke Kaifu from the University of Tokyo simulated methods ancient peoples would have needed to accomplish these journeys, and they used period-accurate tools to create the canoes to make the journey themselves.

The enigmatic stone alignments in the Carnac region of Brittany, France, are among the most famous megalithic monuments in Europe – alongside Stonehenge, Menga, and the megalithic temples of Malta. For the first time, it has now been possible to date parts of these alignments with a higher precision and gain new insights into their function.
