In brief
This groundbreaking study provides insights into how early humans successfully navigated vast ocean currents using primitive technology, revealing their incredible maritime skills.
In an ambitious attempt to explore human maritime history, a team of Japanese researchers embarked on a journey inspired by ancient migratory patterns. Led by Yousuke Kaifu of the University of Tokyo, the team constructed a dugout canoe, a replica of vessels used thousands of years ago, to investigate how early humans might have traversed the open ocean from Taiwan to the islands of southern Japan, including Okinawa.The expedition was reminiscent of Thor Heyerdahl's 1947 Kon-Tiki journey, where he set sail from Peru to support his theory about ancient trans-Pacific navigation. This time, however, the focus was on understanding the capabilities of prehistoric seafarers who, over 30,000 years ago, faced the mighty Kuroshio current with no maps or metal tools.Published in the academic journal Science, the findings are based on two studies that emerged from the experimental archaeology approach. Advanced ocean modeling created simulations of numerous potential routes taken by ancient navigators. According to Dr. Kaifu, various seasonal conditions and paddling techniques were analyzed to uncover the optimal pathways for migrating across the ocean.The experimental journey itself saw Kaifu and his crew—four men and one woman—paddle the 25-foot canoe, named Sugime, across 122 nautical miles from eastern Taiwan to Yonaguni Island. Relying on natural cues from the stars, sun, and wind for navigation, the team undertook a challenging 45-hour journey. At times, the team found themselves visually lost, without any sight of their destination, echoing the true challenges ancient mariners might have faced.Peter Bellwood, an archaeologist not directly involved in the research, noted the significance of this crossing, considering it one of the earliest and longest maritime migrations of Homo sapiens. The study not only highlights the historical significance of ancient sea voyages but also sheds light on the remarkable skills and resilience of early human navigators. By retracing these steps, the research team has contributed valuable knowledge to the understanding of human migration and adaptation to oceanic travel long before contemporary navigation methods.
