Late colonization of Easter Island.

چکیده
Easter Island (Rapa Nui) provides a model of human-induced environmental degradation. A reliable chronology is central to understanding the cultural, ecological, and demographic processes involved. Radiocarbon dates for the earliest stratigraphic layers at Anakena, Easter Island, and analysis of previous radiocarbon dates imply that the island was colonized late, about 1200 A.D. Substantial ecological impacts and major cultural investments in monumental architecture and statuary thus began soon after initial settlement.

9 Abstract Easter Island, a remote island in the Pacific 10 Ocean, is currently primarily covered by grasslands, but 11 paleoecological studies have shown the former presence of 12 different vegetation. Much of its original biota has been 13 removed during the last two millennia, most likely by 14 human activities, and little is known about the native flora. 15 Macrofossil and pollen analyses o...
