Ongoing research at the Chelechol ra Orrak rockshelter in Palau, Micronesia, has revealed the presence of one of the oldest (ca. 3000-1700 BP) and most demographically diverse cemeteries in the Pacific. Archaeological excavation of only a small portion of the site indicates that dozens of individuals were buried here for more than a millennia. Subsequent osteological analysis coupled with recent attempts to extract ancient DNA and stable isotopes (Sr and Pb) have shed new light on genetic affinities and population movements within and between islands in the archipelago. Results provide important opportunities for examining the origins of colonizers to Palau and their relationship with other groups in the western Pacific.
