Archaeological Roots of Human Diversity in the New World: A Compilation of Accurate and Precise Radiocarbon Ages from Earliest Sites
A compilation of 63 stratigraphic situations with evidence for human presence and two or more radiocarbon ages older than 10,500 B.P. has been processed to increase the accuracy and precision of the estimated ages and to compare their distributions at hemispheric scale. The compilation was developed...
