Aeta, Agta and Dumagat, are collective terms for several indigenous peoples who live in various parts of Luzon islands in the Philippines. They are included in the wider Negrito grouping of South and Southeast Asia, with whom they share superficial common physical characteristics such as: dark skin tones; short statures; frizzy to curly hair; and a higher frequency of naturally lighter hair colour (blondism) relative to the general population. They are thought to be among the earliest inhabitants of the Philippines—preceding the Austronesian migrations. Regardless, the modern Aeta populations have significant Austronesian admixture, and speak Austronesian languages.
