Older than we thought: Implications of corrected dates for Paleoindians

Radiocarbon dates for the terminal Pleistocene are about 2,000 years too young. Furthermore, because significant carbon perturbations that are manifest as plateaus or abrupt jumps in age, radiocarbon dates of ca. 12,500 to 10,000 B.P. [C-14] must be critically evaluated. The first successful human colonization of the Americas occurred not 11,500 brit about 13,500 years ago. This basic chronological revision has important implications for models of Paleoindian colonization, population expansion, and ge,lc tic and linguistic divergence.
