Axes were computed using three present-day populations (bottom right legend), and other present-day (no fill) and ancient (large filled symbols; newly reported with black outline) individuals were projected and plotted using the first two PCs. Colors correspond to genetic clusters centered around the Solomon Islands (red), New Ireland (orange), New Britain (blue), New Guinea (black), and Polynesia and Taiwan (green). N. G., New Guinea; Polyn., Polynesian; Van., Vanuatu; anc., ancient.
