Exploring Ancient Waters: Scientists Recreate Prehistoric Voyages with a Traditional Canoe

According to a recent publication by Reuters, our ancestors emerged in Africa around 300,000 years ago and eventually made their way across the globe, reaching some of the most isolated regions on Earth. This remarkable journey raises an intriguing question: how did they manage such feats with only basic technology at their disposal?

To explore this mystery,a team of researchers embarked on an experimental expedition across the East China Sea.They paddled from Ushibi in eastern Taiwan to Japan’s Yonaguni Island using a dugout canoe crafted from a Japanese cedar tree. this canoe, named Sugime, was built using tools reminiscent of those used by Paleolithic people about 30,000 years ago.

The crew consisted of four men and one woman who undertook this challenging voyage that lasted over 45 hours and covered approximately 140 miles (225 km). They faced one of the strongest ocean currents in the world—the Kuroshio—while battling fatigue and taking necessary breaks as they drifted at sea.Despite these challenges,they successfully reached Yonaguni.

Navigating like ancient mariners would have done—by observing celestial bodies and ocean swells—the voyagers were accompanied by two escort boats for safety. The ryukyu Islands chain includes Yonaguni and stretches down to taiwan from Kyushu, Japan’s southernmost main island.

Interestingly enough, previous attempts using reed or bamboo rafts had failed due to their lack of speed and durability against strong currents. “Through our trials—and many errors—we gained insight into just how tough ocean crossings can be,” remarked Yousuke Kaifu from the University of Tokyo.He emphasized that skilled paddling combined with dugout canoes could indeed allow ancient peoples to navigate these waters despite important risks.

Archaeological findings suggest that around 30 millennia ago people first crossed from Taiwan to various Ryukyu islands like Okinawa—a feat puzzling scientists given their limited technology at that time: no maps or metal tools were available; only primitive vessels existed alongside formidable currents akin to today’s Gulf Stream off Mexico.

This research echoes historical explorations like Thor Heyerdahl’s famous Kon-Tiki expedition in 1947 when he demonstrated how prehistoric peoples might have traveled vast distances across oceans using simple rafts originating from South America towards Polynesia—a theory now debated but groundbreaking for its time.

Kaifu noted that while Heyerdahl’s ideas have been challenged over time due to new evidence emerging since then, modern studies provide more accurate models for understanding ancient maritime journeys. In another study published alongside theirs in Science Advances journal, simulations indicated that crossing during those times was feasible even when Kuroshio currents were stronger than today’s conditions.

Yu-Lin Chang from the Japan Agency for Marine-Earth Science and Technology added insights regarding variable ocean conditions faced by early navigators which could lead them into unpredictable weather scenarios during voyages—factors contributing significantly toward potential failures along their journeys.

this research not only sheds light on human migration patterns but also highlights our ancestors’ resilience against nature’s challenges while navigating uncharted waters thousands of years ago.
