Researchers Stone Essaure Stone skills against one of the most severe currents on Earth

Archaeologists estimate that humans first reached the Ryukio Islands off the southwestern coast of Japan at some time between 35,000 and 27,500 years. However, how they did so still a mystery, especially since they had to cross one of the strongest surrounding currents on the planet. To address this permanent question, scientists have decided to try the old Stone Age journey.

Using the similar copies of the tools in the Japanese archipelago during the upper Stone Age (about 50,000 to 10,000 years), researchers in Japan built a hidden boat and used it to cross the Strait of 68.4 miles (110 km) between Taiwan and the Yongoni Island, including the powerful korocio iron, in about 45 hours. The successful journey represents a possible way for people in Taiwan at the present time, may have traveled to the islands of tens of thousands of years.

The researchers wrote in the study, which was published today in the study: “Our hideout, which is 7.5 meters long, was manufactured with edge stone axes, quickly and always enough to cross this strait.” Science progress. “This supports the early development of job boats, such as the hideout, while our experience also highlighted that this type of marine travel was only possible for experienced blasphemy who enjoy advanced navigation skills.”

One of the greatest challenges facing prehistoric naval study is the fact that such ancient water vessels made of organic matter, such as wood, may have long been disintegrated. Without direct archaeological evidence, the next best way to shed light on how old people do things through experimental archeology – determining the possible approach to old efforts by physically repeated them in a simulated historical context.

The University of Tokyo Anthropology Yusuki Kaifu and its authors have been trying to reach the Ryukio Islands in the Old Stone Age-with modern navigation techniques such as GPS or compasses-since 2013. The winning design was a boat made of a hollow and polished Japanese rice tree with an interior design of the fire, which was carrying five crew members.

“Given the absence of archaeological residue of the Pelistosini water riding, the potential craft of the ancient sea narrowed by referring to the ethnographic and ethnographic records of the Holosin and considering the availability of materials, technological restrictions of time, and flight capabilities for each craft,” the researchers explained. the HolosinWhich started about 11,700 years ago, is the current time period. “We also aim to investigate the time of travel, the amount of efforts required, and other facts from crossing the old ocean of the first islands south of Ryukio.”

In this spirit, the team has developed computer models to simulate what such a cross may be with the late Peshusine ocean conditions. According to the simulation-which was also identified the integrated data collected during the experimental trip-it was possible to determine the success of the prehistoric trip through the starting point (perfectly, quiet bays), the directional strategy (the first mortar to the southeast, then the northeast), and navigational skills (using stars and the sun).

Moreover, “the study of separate numerical simulation indicates that this type of boat can travel to the UNGONA island from a different northern starting point in Taiwan (Taroko) through both modern and late Pelstosin oceans,” they added. “The ancient Stone Age is often seen as” lower “among the general public, and this is primarily due to their” primitive “culture and their technology. In a sharp contradiction, we (our work) highlighted that they have accomplished something unusual with the primitive technology available to them at the time.

While this Experimental projects It cannot be replaced by direct archaeological evidence, the study joins a group of recent times Practical approach Providing creative theories in the absence of direct material evidence.
