The Pre-Clovis Peoples

Abstract

Scholars have long debated the timing and route by which humans first arrived in the New World. In “Late Upper Paleolithic Occupation at Cooper’s Ferry, Idaho, USA, ~16,000 Years Ago,” published in Science, Loren Davis et al. used radiocarbon dating to establish a chronology for artifacts, and evidence of human activity, that has pushed migration 2,800 years earlier than previously thought.
