Ancestry of first Marianas settlers linked to the Philippines



Ancient DNA analysis obtained from two human skeletons found on Guam dating to around 2,200 years ago suggests that the ancestry of the Mariana Island settlers is linked to the Philippines.


The analysis also suggests a shared genetic drift among the two Guam skeletons to the skeletons of Lapita populations from Vanuatu and Tonga.


The new research was conducted by researchers from the Max Planck Institute for Evolutionary Anthropology, Australian National University and the University of Guam to find out where people came from to get to the Marianas, and how the ancestors of the present Mariana Islanders, the Chamorro, might be related to Polynesians.
