The Andaman and Nicobar Islands, located in the east of the Indian mainland geographically, float in splendid isolation in the Bay of Bengal. Once a hill range extending from Myanmar to Indonesia, these picturesque undulating islands, islets numbering around 572, are covered with dense rain-fed, damp and evergreen forests and endless varieties of exotic flora and fauna. Most of these islands (about 550) are in the Andaman Group, 28 of which are inhabited. The smaller Nicobars, comprise some 22 main islands (10 inhabited). The Andaman and Nicobars are separated by the Ten Degree Channel which is 150 Kms. wide.
These islands also boast of freedom fighting days’ historically significant landmarks viz. Cellular Jail, Ross Island, Viper Island, Hopetown and Mount Harriet. The Andaman and Nicobar Islands have been declared as two of the 218 endemic bird area of the world. As many as 270 species and sub-species of birds have been reported existing in these islands, 106 of them being endemic. The Andaman Wood Pigeon, Andaman Padauk and Dugong are declared as State Bird, State Tree and State Animal respectively. There are about 96 Wildlife Sanctuaries, nine National Parks and one Biosphere Reserve in the islands. These islands are blessed with the bounties of both south-west and north-east monsoons.
The Andaman & Nicobar Islands have been inhabited for several thousand years, at the very least. The earlier archaeological evidence yet documented goes back some 2,200 years; however, the indications from genetic, cultural and linguistic isolation studies point to habitation going back 30,000 – 60,000 years, well into the Middle Palaeolithic. In the Andaman Islands, the various Andamanese people maintained their separated existence through the vast majority of this time, diversifying into distinct linguistic, cultural and territorial groups. By the 1850s when they first came into sustained contact by outside groups, the indigenous people of Andamans were: the Great Andamanese, who collectively represented at least 10 distinct sub groups and languages; the Jarawa: the jungle (or Rutland Jarawa); the Onge; and the Sentinelese (the most isolated of all the groups). The indigenous peoples of the Nicobars (unrelated to the Andamanese) have a similarly isolated and lengthy association with the islands. There are two main groups: the Nicobarese, or Nicobari living throughout many of the islands; and the Shompen, restricted to the interior of Great Nicobar./span>
