Andaman and Nicobar Islands consist of mainly two groups of islands, with distinctive features of the original residents — Negroid and Mongolese. It is strange to see how these two different groups migrated to these islands so far from the mainland — from India and Myanmar. The aboriginals found in these islands are the Jarawas, Sentineles, Onges, Shompenites, mainly found in Andaman and the Nicobarese in Nicobar. Of these, the Nicobarese in general, and some of the Onges, have accepted the so-called modern civilisation and learned the use of modern tools and facilities.

They can be seen frequently in the Port-Blair market. The aboriginals are looked after by the Anthropological Department of the Government, who make regular visits to their islands and supply them with food and other necessities.

These aboriginals still do not know how to use a matchbox and prepare fire by rubbing two pieces of wood; they also do not know the use of cloth. If the people from the Anthropological Department offer them clothes, they use them only as turbans and not to wrap their bodies.
