North Sentinel Island

North Sentinel Island is one of the tribe inhabited island in the Bay of Bengal near India. Inhabitants of the island have been living there for about 60,000 years and to this day remain completely untouched by modern civilization. They were visited extensively in the 1990s. It was found that they hunt wild pig, their songs contain two notes, and their only form of art is body painting. Researchers compare them to humans 15,000 years ago. In 2006, two fishermen were killed by the Sentinelese when their boat drifted too close to their shore and since then there has been no contact between them and the rest of the world. Since then any intruders on their island have been met with lethal hostility and therefore Indian government has established a 3-mile exclusion zone around the island.
