45-hour voyage in replica canoe tests Paleolithic migration theory

Earlier this week, we reported on a Swedish archaeologist who spent the last three years sailing the fjords in a replica boat similar to those the Vikings may have used. Not to be outdone, Japanese researchers have followed suit, building their own seaworthy dugout canoe with Paleolithic-era tools to cross between Taiwan and Yonaguni Island, where one of the world’s strongest ocean currents, the Kuroshio, remains active. They presented their findings in two new papers published in the journal S

Researchers Pit Stone Age Seafaring Skills Against One of Earth’s Fiercest Currents

Archaeologists estimate that humans first arrived on the Ryukyu Islands off the southwestern coast of Japan sometime between 35,000 and 27,500 years ago. How they did so, however, remains a mystery, especially since they would have had to cross one of the planet’s strongest ocean currents. To address this enduring question, scientists decided to attempt the Paleolithic voyage themselves. Using replicas of tools that existed in the Japanese Archipelago during the Upper Paleolithic (around 50,000
