Maybe we do know when people first came to North America ; and what does it mean if we do ?

چکیده
The history of research in North America suggests that we already know when people arrived in the continental US: about 11,500 C yr BP. Research also suggests that people were in the southern cone of South America by a comparable age, if not earlier. If the New World was colonized by Late Pleistocene migrants from Asia via the Bering Strait, then the earliest sites should be in North not South America. Several possibilities might account for this apparent paradox: (a) the inability to locate pre-11,500 C yr BP sites in North America, (b) asynchroneity of late Pleistocene/early Holocene C dates between North and South America, (c) inaccurate dating of South American sites, or (d) a coastal migration that by-passed interior North America. All these possibilities currently appear unlikely, and the paradox resists explanation at this date. r 2002 Published by Elsevier Science Ltd.
