a pre-lapita origin in the bismarcks is also supported by a further major subclade, b4a1a1a1, nested within the motif clade, defined by a transition at position 6905 (figure s1), dating to 6.8 (95% ci: 3.7, 9.8) ka via complete mtdnas. it was carried into remote oceania but has not been detected in indonesian west papua and has been observed in only one sample from the north coast of papua new guinea. most likely, the clade arose after the main redispersal of the polynesian motif to the west or, at least, was present at a lower frequency at that time and was therefore not carried by the dispersal into isea.
