8) Polynesians and other Pacific Islanders are genetically
linked to Filipinos. The Philippine Islands served as a crucial
gateway for the spread of Austronesian-speaking populations into
the rest of Southeast Asia and the remote islands of the Pacific.
A series of ancient DNA studies since 2015 has provided a better
picture on this important phase of Asia-Pacific prehistory. The first
seminal study is the analyses on the oldest Lapita individuals of
Vanuatu, dated ~3,000 years old, by Skoglund et al. (2015). The
study revealed that the oldest Lapita individuals were most
genetically linked to Filipinos. This is especially significant given
that the Lapita culture is regarded as the predecessor of presentday Polynesian, some Micronesian, and some coastal
Melanesian culture in the islands of the Pacific. Accordingly, the
study portrays a lasting legacy of Filipinos into the genetic makeup of islander populations in the Pacific.
Another study by Pugach et al., looked at the genetic profile of
two ancient individuals from Guam, Mariana Islands in the
western Pacific. The ancient individuals, dated ~2,200 years old,
revealed to have a genetic ancestry that is linked to Filipino ethnic
groups relative to all other worldwide set of populations. This
suggests that the ancestor Chamorro people of Mariana Islands
likely originated from a coastal population inhabiting the
Philippines. Future work still needs to be done, including a
comprehensive analysis on Philippine, Indonesian, and
Taiwanese ancient populations. Such study with wide geographic
coverage will aid us in pinpointing the specific coastal source
population who migrated into the Marshall Islands and distantly
into the coasts of Bismarck archipelago and Vanuatu Islands.
