Explanation:

The tribal population in Andaman and Nicobar Islands belongs to the Negroid race. The Andaman Islands are home to four \'Negrito\' tribes – the Great Andamanese, Onge, Jarawa and Sentinelese.
Negroid (less commonly called Congoid) is an obsolete racial grouping of various people indigenous to Africa south of the area which stretched from the southern Sahara desert in the west to the African Great Lakes in the southeast, but also to isolated parts of South and Southeast Asia (Negritos).
