The First Americans

Fresh discoveries are redefining our understanding of when and how humans first migrated into the Americas. Archaeological evidence now firmly suggests human occupation began some 15,500 years ago, not 13,000 years ago, as previously thought. In 2014 advances in DNA analysis enabled the first sequencing of a full Paleo-American genome, at the Anzick site in western Montana—confirmation that the ancestors of modern Native Americans did indeed originate from a population in Asia.
