Abstract

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

Résumé

Résumé

Las fechas radiocarbónicas para el final de Pleistoceno son alrededor de 2.000 años más jóvenes de lo que realmente son. Además, por causa de perturbaciones significativas de carbón que son manifestadas como mesetas o saltos abruptos de edad, las fechas radiocarbónicas de 12.500 a 10.000 a.p. [14C] deben evaluarse con extremo cuidado. La primera colonización humana del continente americano que tuvo éxito ocurrió, no 11.500, pero 13.500 años atrás. Esta revisión básica de cronología tiene implicaciones importantes para los modelos de colonización de los Paleoindios, el crecimiento de su población, y su divergencia genética y lingüística.
