Characterized by shortness of stature, darkness of pigmentation, and kinky hair, the Negritos constitutes one of the most complex populations of indigenous people and are widely of dispersed in the whole archipelago. In popular beliefs, two major races landed in the Philippine archipelago between 30,000 to 20,000 years ago.
One moving on the eastern flank going up to the north to the Pacific side of the Sierra Madre mountains like the Alta, Arta, and Agta groups; the second group moved along the western side, similarly going up northern Luzon which now includes the Pinatubo Negrito. Other corresponding major subgroupings are the Dumagat, Ata, Ati, Atta, Sinauna, and Batak.
Nowadays, they are widely distributed and found in highland areas like in the Pacific side of northern Luzon to the Bicol peninsula, the northern tip of the Cordillera, the Zambales ranges and the Bataan peninsula, Bondoc peninsula, and the islands of Negros, Panay, Palawan and other more.
