text: "East Polynesia colonized faster and more recently than previously thought"

  "The study was based on an analysis of the validity of more than 1,400 radiocarbon dates from 47 islands in the region collected from their own and other researchers' published studies.
  Polynesian ancestors settled in Samoa around 800 B.C., then much later moved to colonize the region in two distinct phases—earliest in the central Society Islands between A.D. 1025 and 1120, four centuries later than previously assumed. Then, between 70 and 265 years later, dispersal continued in one major ‘pulse’ to all remaining islands including New Zealand, Hawai`i and Easter Island (Rapa Nui) between A.D. 1190 and 1290. The timing and sequence of this remarkable event has been highly debated and poorly resolved, precluding the understanding of cultural and ecological change that followed".
