Specifically, archeologists at the University of Tokyo demonstrated long distance canoe travel across the Pacific Ocean, which demonstrates how the Austronesian people could have spread throughout the region.
Long-standing questions about the migration of early modern humans in East Asia may finally be answered, thanks to a rare and remarkable journey made in a dugout canoe.Once again, we see that our ancestors were far more capable than was previously thought.
The timing and destinations of the earliest modern human migrations into East Asia are fairly well established. What remains unclear is how these early populations managed to travel between islands separated by dangerous ocean passages.
To address this gap, a research team from Japan and Taiwan, led by Professor Yousuke Kaifu of the University of Tokyo, explored the types of methods ancient people might have used. They also recreated the journey themselves, building canoes with replicas of the tools available at the time.
Archaeological and environmental evidence indicates that roughly 30,000 years ago, humans completed a sea voyage from what is now Taiwan to islands in southern Japan, such as Okinawa—without the aid of maps, metal tools or modern seafaring vessels. To better understand how this journey could have taken place, Kaifu’s team conducted both experimental reconstructions and computer-based simulations.
One of their two recent studies used digital modeling to test how a vessel could cross the powerful Kuroshio Current, one of the world’s most forceful ocean flows. The results demonstrated that a craft built with Paleolithic-era tools and navigational knowledge could indeed manage the crossing. The second study focused on building and trialing an actual canoe, which the team used to paddle more than 100 kilometers between islands, successfully replicating the hypothesized ancient route.
