The study deciphers entire DNA of "three individuals from Vanuatu (about 3,100–2,700 years before present) and one from Tonga (about 2,700–2,300 years before present)," fuh out from ancient graves. Locations of Babuatu and Tonga are in Figure 1, left panel.

"our modelling indicates that Philippine populations (Kankanaey) are the closest outgroup to the First Remote Oceanians, indigenous Taiwanese (Atayal) second closest, and mainland southeast Asians such as the Dai most remote, consistent with models of population movement along a route from Taiwan to the Philippines to Near Oceania to Remote Oceania."

Then go to Figure 3, panels b-e, to see how each waves of migration populate that part of the world.

("Subsequent study of the nuclear genome from this specimen suggests that Denisovans shared a common origin with Neanderthals, that they ranged from Siberia to South-East Asia, and that they lived among and interbred with the ancestors of some modern humans, with about 3% to 5% of the DNA of Melanesians and Aboriginal Australians deriving from Denisovans")
