The cultural achievements of pre-colonial Philippines include those covered by prehistory and early history of the Philippines archipelago and its inhabitants, which are the indigenous forebears of today's Filipino people. These early Filipinos possessed a culture and technology that were quite advanced considering the timeline of history of science when it flourished. Waves of migrants who came to settle in the islands contributed to the development of ancient Philippine civilization. Prehistoric aborigines, a cross of Afro-Asiatic and Austro-Aborigines, now called Negritos (Aeta, Agta, Ayta) reached the islands by way of land bridges around 15,000 to 30,000 BC, and they were excellent hunters and food gatherers. In its midst, other ancient civilizations were also thriving and evolving. The Proto-Malays, a Mongol-Asiatic race, arrived around 2500 BC using oceanic vessels called balangays, and they brought with them their knowledge in seafaring, farming, building of houses from trees and creation of fire for cooking.
