Artefacts and human remains taken by a Norwegian explorer in the late 1940s as part of the famous Kon-Tiki expedition are being returned to Chile’s Easter Island in the mid-Pacific. In 1947, the anthropologist and adventurer Thor Heyerdahl sailed on a log raft named Kon-Tiki from Peru to Polynesia in 101 days in order to prove his theory – that the South Sea Islands were settled by seafarers from South America.
