A 2021 genetic study examining representatives of 115 indigenous communities found evidence of at least five independent waves of early human migration. Negrito groups, divided between those in Luzon and those in Mindanao, may come from a single wave and diverged subsequently, or through two separate waves. This likely occurred sometime after 46,000 years ago. Another Negrito migration entered Mindanao sometime after 25,000 years ago. Two early East Asian waves were detected, one most strongly evidenced among the Manobo people who live in inland Mindanao, and the other in the Sama-Bajau and related people of the Sulu archipelago, Zamboanga Peninsula, and Palawan. The admixture found in the Sama people indicates a relationship with the Htin and Mlabri people of mainland Southeast Asia, both peoples being speakers of an Austroasiatic language and reflects a similar genetic signal found in western Indonesia. These happened sometime after 15,000 years ago and 12,000 years ago respectively, around the time the last glacial period was coming to an end. Austronesians, either from Southern China or Taiwan, were found to have come in at least two distinct waves. The first, occurring perhaps between 10,000 and 7,000 years ago, brought the ancestors of indigenous groups that today live around the Cordillera Central mountain range. Later migrations brought other Austronesian groups, along with agriculture, and the languages of these recent Austronesian migrants effectively replaced those existing populations. In all cases, new immigrants appear to have mixed to some degree with existing populations. The integration of Southeast Asia into Indian Ocean trading networks around 2,000 years ago also shows some impact, with South Asian genetic signals present within some Sama-Bajau communities. There is also some Papuan migration to Southeast Mindanao as Papuan genetic signatures were detected in the Sangil and Blaan ethnic groups.
