The Aeta were included in the group of people termed "Negrito" during Spanish colonial rule as Negritos. Various Aeta groups in northern Luzon are known as "Pugut" or "Pugot," a name designated by their Ilocano-speaking neighbors, and which is the colloquial term for those with darker complexions. In Ilocano, the word also means "goblin" or "forest spirit."
The history of the Aeta continues to confound anthropologists and archaeologists. One theory suggests that the Aeta are the descendants of the original inhabitants of the Philippines, who, contrary to their sea-faring Austronesian neighbors, arrived through land bridges that linked the country with the Asian mainland about 30,000 years ago. Unlike many of their Austronesian counterparts, the Aetas have shown resistance to change. The attempts of the Spaniards to settle them in reducciones or reservations all throughout Spanish rule failed.
Mining, deforestation, illegal logging, and slash-and-burn farming has caused the indigenous population in all parts of the Philippines to steadily decrease to the point where they number in the thousands today. The Philippines affords them no protection. In addition, the Aeta have become extremely nomadic due to social and economic strain on their culture and way of life that had previously remained unchanged for thousands of years. The Aeta have no sense of money or land ownership and sometimes can be seen camping out in city parks or panhandling.
While resisting change from the other society for hundreds of years, the Aetas have adjusted to social, economic, cultural, and political pressures with remarkable resilience; they have created systems and structures within their culture to cushion the sudden impact of change.
The Aetas are also animists. For example, the Pinatubo Aeta believe in environmental spirits such as anito and kamana. They believe that good and evil spirits inhabit the environment, such as the spirits of the river, sea, sky, mountain, hill, valley, and other places.
No special occasion is needed for the Aeta to pray, although there is a clear link between prayer and economic activities. The Aeta dance before and after a pig hunt. The night before Aeta women gather shellfish, they perform a dance which is partly an apology to the fish and partly a charm to ensure the catch. Similarly, the men hold a bee dance before and after the expeditions for honey.
Their traditional clothing is very simple. The young women wear wrap around skirts. Elder women wear bark cloth, while elder men wear loin cloths. The old women of the Agta wear a bark cloth strip which passes between the legs, and is attached to a string around the waist. Today most Aeta who have been in contact with lowlanders have adopted the T-shirts, pants and rubber sandals commonly used by the latter.
Women exclusively weave winnows and mats. Only men make armlets. They also produce raincoats made of palm leaves whose bases surround the neck of the wearer, and whose topmost part spreads like a fan all around the body.
Other "decorative disfigurements" include the chipping of the teeth. With the use of a file, the Dumagat mutilate their teeth during late puberty. The teeth are dyed black a few years afterwards.
The Aetas generally use ornaments typical of people living in subsistence economies. Flowers and leaves are used as earplugs for certain occasions. Girdles, necklaces, and neckbands of braided rattan incorporated with wild pig bristles are frequently worn.
