Jarawa Tribe--The Desecendants of the Frst Humans

Prehistory and origins
Along with other indigenous Andamanese peoples, they have inhabited the islands for at least several thousand years, and most likely a great deal longer. The Andaman Islands have been known to outsiders since antiquity however, until quite recent times they were infrequently visited, and such contacts were predominantly sporadic and temporary. For the greater portion of their history their only significant contact has been with other Andamanese groups; the experience of such a lengthy period of isolation almost completely lacking in external cultural influences is equaled by few other groups in the world, if at all^.
There is some indication that the Jarawa regarded the now-extinct Jangil tribe as a parent tribe from which they split centuries or millennia ago, even though the Jarawa outnumbered (and eventually out-survived) the Jangil. The Jangil (also called the Rutland Island Aka Bea) were presumed extinct by 1931, sixteen years prior to Indian independenceContact, settlements and dislocation

(a) Rapid depopulation of the original southeastern Jarawa homeland in the 1789-1793 period
(b) Onge and Great Andamanese shrinkage to isolated settlements
(c) Complete Jangil extinction by 1931
(d) Jarawa move to occupy depopulated former west coast homeland of the Great Andamanese
(e) Only the Sentinelese zone is somewhat intact

Before the 19th century, the Jarawa homelands were located in the southeast part of South Andama Island and nearby islets. With the establishment of the initial British settlement, these are suspected to have been largely depopulated by disease shortly after 1789. The Great Andamanese tribes were similarly decimated by disease, alcoholism and British government-sponsored destruction, leaving open the western areas which the Jarawa gradually made their new homeland. The immigration of mainland Indian and Karen (Burmese) settlers, beginning about two centuries ago, accelerated this process. Prior to their initiating contact with settled populations in 1997, they were noted for vigorously maintaining their independence and distance from external groups, actively discouraging most incursions and attempts at contact. Since 1998, they have been in increasing contact with the outside world and have increasingly been the choosers of such contact. All contact, especially with tourists, remains extremely dangerous to the Jarawa due to the risk of disease. Of the remaining Andamanese peoples, only the Sentineless have been able to maintain a more isolated situation, and their society and traditions persist with little variance from their practices they observed before the first significant contacts were made. Today the Jarawa are in regular contact with the outside world through settlements on the fringes of their Reserve, through daily contact with outsiders along the Andaman Trunk Road and at jetties, marketplaces and hospitals near the road and at settlements near the reserve, with some children even showing up at mainstream schools and asking to be educated along with settler children.
