The Andamanese are the indigenous peoples of the Andaman Islands, part of India's Andaman and Nicobar Islands union territory in the southeastern part of the Bay of Bengal in Southeast Asia. The Andamanese peoples are among the various groups considered Negrito, owing to their dark skin and diminutive stature. All Andamanese traditionally lived a hunter-gatherer lifestyle, and appear to have lived in substantial isolation for thousands of years. It is suggested that the Andamanese settled in the Andaman Islands around the latest glacial maximum, around 26,000 years ago. The Andamanese peoples included the Great Andamanese and Jarawas of the Great Andaman archipelago, the Jangil of Rutland Island, the Onge of Little Andaman, and the Sentinelese of North Sentinel Island. At the end of the 18th century, when they first came into sustained contact with outsiders, an estimated 7,000 Andamanese remained. In the next century, they experienced a massive population decline due to epidemics of outside diseases and loss of territory. Today, only roughly 400–450 Andamanese remain, with the Jangil being extinct. Only the Jarawa and the Sentinelese maintain a steadfast independence, refusing most attempts at contact by outsiders. The Andamanese are a designated Scheduled Tribe in India's constitution. History Until the late 18th century, the Andamanese culture, language, and genetics were preserved from outside influences by their fierce reaction to visitors, which included killing any shipwrecked foreigners, and by the remoteness of the islands. The various tribes and their mutually unintelligible languages thus are believed to have evolved on their own over millennia. Venetian explorer Marco Polo wrote of the Andamanese in 1294, in The Travels of Marco Polo: Origins According to Chaubey and Endicott (2013), the Andaman Islands were settled less than 26,000 years ago, by people who were not direct descendants of the first migrants out of Africa. According to Wang et al. (2011), It was previously assumed that the Andaman ancestors were part of the initial Great Coastal Migration (South-Eurasians or Australasians) that was the first expansion of humanity out of Africa, via the Arabian peninsula, along the coastal regions of the South Asia towards Insular Southeast Asia, and Oceania. The Andamanese were considered to be a pristine example of a hypothesized Negrito population, which showed similar physical characteristics, and was supposed to have existed throughout southeast Asia. The existence of a specific Negrito-population is nowadays doubted. Their commonalities could be the result of evolutionary convergence and/or
