ABSTRACT The central lowland of Beringia (aka the Bering land bridge) has been viewed alternately as a barrier or a refugium to the Native American founder population during the Last Glacial Maximum (LGM). Here we suggest that an equally – if not more – likely LGM home for the founder population is the arctic zone of Beringia. People were drawn to eastern arctic Beringia during the post-LGM Younger Dryas (YD) cold period and occupied western arctic Beringia during the cold interval preceding the LGM (GS5/HE3). Arctic Beringia probably contained adequate resources for an LGM human population, especially across the exposed East Siberian Arctic Shelf (“Northwest Beringian Plain”), which supported an extensive steppe-tundra habitat populated by mammoth and other large mammals before and during the LGM. An arctic Beringian refugium would explain a growing body of evidence that indicates an early (or pre-) LGM divergence of the Native American founder population from its Asian source.

期刊介绍:
PaleoAmerica disseminates new research results and ideas about early human dispersal and migrations, with a particular focus on the Americas. It fosters an interdisciplinary dialog between archaeologists, geneticists and other scientists investigating the dispersal of modern humans during the late Pleistocene. The journal has three goals: First and foremost, the journal is a vehicle for the presentation of new research results. Second, it includes editorials on special topics written by leaders in the field. Third, the journal solicits essays covering current debates in the field, the state of research in relevant disciplines, and summaries of new research findings in a particular region, for example Beringia, the Eastern Seaboard or the Southern Cone of South America. Although the journal’s focus is the peopling of the Americas, editorials and research essays also highlight the investigation of early human colonization of empty lands in other areas of the world. As techniques are developing so rapidly, work in other regions can be very relevant to the Americas, so the journal will publish research relating to other regions which has relevance to research on the Americas.
