Here are some interesting links on the people of the Andaman and Nicobar islands, a restricted area that some were criticizing India for not allowing outside aid, aside from Indian, into.
The Sentinelese are supposed to be the last true Paleolithic people, and once had this delightful encounter with a film crew:
In the spring of 1974, North Sentinel was visited by a film crew that was shooting a documentary titled Man in Search of Man, along with a few anthropologists, some armed policemen, and a photographer for National Geographic. In the words of one of the scientists, their plan was to "win the natives' friendship by friendly gestures and plenty of gifts." As the team's motorized dinghy made its way through the reefs toward shore, some natives emerged from the woods. The anthropologists made friendly gestures. The Sentinelese responded with a hail of arrows. The dinghy proceeded to a landing-spot out of arrow range, where the policemen, dressed in padded armor, disembarked and laid gifts on the sand: a miniature plastic automobile, some coconuts, a tethered live pig, a child's doll, and some aluminum cookware. Then they returned to the dinghy and waited to observe the natives' reaction to the gifts. The natives' reaction was to fire more arrows, one of which hit the film director in the left thigh. The man who had shot the film director was observed laughing proudly and walking toward the shade of a tree, where he sat down. Other natives were observed spearing the pig and the doll and burying them in the sand. They did, however, take the cookware and the coconuts with evident delight.
