A crew of archaeologists affiliated with a number of establishments in Chile reviews proof that early settlers on the island of Rapa Nui sailed to South America, interacted with individuals dwelling there after which returned. Of their examine, revealed in PLOS ONE, the group analyzed plant materials discovered on obsidian blades made by the early settlers.
Prior analysis has proven that there have been individuals dwelling on Rapa Nui in the course of the years 1000 to 1300, although their origin remains to be not identified—these early settlers are most well-known for his or her large stone carvings of human figures.
On this new examine, the analysis crew discovered proof that a number of the settlers sailed all the best way to the coast of South America and again. Such a voyage would have entailed crusing a technique for 3,700 kilometers and sure would have taken wherever from one to 2 months, relying on the climate.
Prior analysis has discovered that the oral historical past of the Rapu Nui individuals consists of reviews of at the least one journey made by the early settlers to South America. On this new effort, the analysis crew adopted up on such reviews by digging up and learning obsidian blades at a website known as Anakena, the earliest identified settlement on the island. The researchers discovered very small quantities of plant materials on the blades, proof that they had been used to course of plant-based meals.

An evaluation of the plant materials confirmed proof of cassava, breadfruit, purple yam, taro, achira, ginger and the Tahitian apple. Of these, the Tahitian apple and breadfruit stood out as a result of neither grows naturally on Rapa Nui—and ginger had by no means been seen earlier than in distant elements of Oceania.
Cassava, candy potato and achira stood out for a unique purpose—all three are South American meals. Additionally they famous that the candy potato remnants had been discovered within the deepest elements of the dig website, suggesting that they arrived on the island in the course of the early years of the settlement.
The researchers conclude that early Rapu Nui settlers ventured to South America and again, maybe a number of occasions. They additional counsel that a number of the meals they introduced again with them was planted and used to develop crops over the following years.
