New evidence for the antiquity of man in North America deduced from aspartic acid racemization
J L Bada et al. Science. 1974.
Abstract
Ages of several Californzia Paleo-Indlian skeletons have been deduced from the extent of aspartic acid racemization. These dates suggest that man was present in North America at least 50,000 years before the present.
