 They all belong to Haplogroup B4a1a1a, the typical 'Polynesian motif'.aDNA analysis shows that the three individuals cluster together with another Lapita sample, dating to around 2,680 to 2,340 years old, taken from Talasiu, Tongatapu, Tonga; all together, the samples form a genetically distinct population when compared against modern populations.When compared against modern populations, the ancient samples from Teouma and Talasiu are genetically closest to the Ami and Atayal people from Taiwan, and the Kankanaey people from the northern Philippines, while sharing little similarity with modern Papuans.
