Correct Option (d)
The indigenous tribal communities inhabiting the Andaman Islands, including the Great Andamanese, Jarawa, Onge, and Sentinelese, are anthropologically classified as belonging to the Negroid racial stock. These groups exhibit distinct physical characteristics associated with this classification and are believed to have African ancestry, representing some of the earliest human migrations into the region, followed by thousands of years of isolation. While the question refers to "Andaman and Nicobar Islands," the Negroid classification specifically applies to the tribes of the Andaman group, which are often the primary reference for the archipelago's distinct tribal populations.
Incorrect Options
- Australoid race: This racial classification is primarily associated with certain tribal populations found in peninsular India, such as those in the Chotanagpur plateau, and is not applicable to the indigenous tribes of the Andaman and Nicobar Islands.
- Caucasoid race: This racial group is generally associated with populations in North India, Central Asia, and Europe. It does not describe the indigenous tribal communities of the Andaman and Nicobar Islands.
- Mongoloid race: While some tribal groups in the Nicobar Islands, specifically the Nicobarese and Shompens, are classified under the Mongoloid racial stock, reflecting Southeast Asian affinities, this classification does not apply to the distinct indigenous tribes of the Andaman Islands, which are of Negroid origin. Therefore, it is not the comprehensive or primary classification for "the tribal population" of the entire Andaman and Nicobar Islands in the context of the given options.
