and Native South Americans, published in Nature in July 2020, has revealed that several eastern Polynesian populations have signs of an ancient genetic signature that originated from Native South American people. An initial admixture event between Native South Americans and Polynesians, discovered by statistical analysis, took place around 1150–1230 CE. Later Recreations of Kon-Tiki Seven Little Sisters In 1954, William Willis sailed alone on a raft Seven Little Sisters from Peru to American Samoa, successfully completing the journey. He sailed , which was farther than Kon-Tiki. In a second great voyage ten years later, he rafted from South America to Australia with a metal raft Age Unlimited. Kantuta In 1955, the Czech explorer and adventurer Eduard Ingris attempted to recreate the Kon-Tiki expedition on a balsa raft called Kantuta. His first expedition, Kantuta I, took place in 1955–1956 and led to failure. In 1959, Ingris built a new balsa raft, Kantuta II, and tried to repeat the previous expedition. The second expedition was a success. Ingris was able to cross the Pacific Ocean on the balsa raft from Peru to Polynesia. Tahiti-Nui A French seafarer, Éric de Bisschop, committed himself in a project he had had for some years: he built a Polynesian raft in order to cross the eastern Pacific Ocean from Tahiti to Chile (contrary to Thor Heyerdahl's crossing); the Tahiti-Nui left Papeete with a crew of five on November 8, 1956. When near the Juan Fernández Islands (Chile) in May 1957, the raft was in a very poor state and they asked for a towing, but it was damaged during the operation and had to be abandoned, but they were able to preserve all the equipment that had been aboard. Tahiti-Nui II A second Tahiti-Nui was built in Constitución, Chile, leaving on April 13, 1958, towards Callao, then towards the Marquesas. It missed its target and after four months, the raft began to sink. The crew built a new smaller raft, the Tahiti Nui III, in the ocean out of the more buoyant parts of the Tahiti Nui II. They were swept towards Cook Islands where on August 30, the raft went aground and was wrecked at Rakahanga atoll. Éric de Bisschop died in this accident. Tangaroa (1965) A Peruvian expedition led by Carlos Caravedo crossed the Pacific Ocean in 1965 in 115 days in a raft named Tangaroa, of which 18 days were used by the
