A genetic link between Indians and two Aeta populations were unveiled in a study whose proponents include Frederick Delfin, university research associate at the DNA Analysis Laboratory in the University of the Philippines, Diliman.
According to Delfin, it is commonly accepted that the Asia-Pacific—including the Philippines—was peopled by human migration that passed through the coast of South Asia.
But the mitochondrial DNA (mtDNA) Indian-Philippine genetic link that Delfin and his team found “can be a signal of shared ancestry that actually originated from India”.
Two mtDNA sets, M52'58 and M52a, that both originate from Indian populations were found in the Aetas of Zambales and the Agtas of Iriga in the Philippines.
These shared common haplogroups show a link between the populations of India and the Philippines that is about 5,000 to 20,000 years old. This suggests that these migratory groups from India arrived before the Austronesian people landed in Philippine shores and populated the prehistoric Philippine archipelago.
