The Andamanese is a collective term to describe the adivasi peoples who are the aboriginal inhabitants of the Andaman Islands, which is the northern district of the Andaman and Nicobar Islands union territory of India, located in the southeastern part of the Bay of Bengal. The term includes the Great Andamanese, Jarawa, Onge, Sentinelese and the extinct Jangil. Anthropologically, they are usually classified as Negritos represented also by the Semang of Malaysia and the Aeta of the Philippines. Their ancestors are thought to have arrived in the islands 60,000 years ago from coastal India as part of the first human peopling of India and Southeast Asia, in the initial expansion of humanity from Africa that began 100,000 years ago. With very little contact with external societies or each other for nearly all this period the tribes have mutually unintelligible languages. This comparatively long-lasting isolation and separation from external influences is unequaled, except perhaps by the aboriginal inhabitants of Tasmania.
