Native American Origins: Reconciling the Evidence of Ancient Genomes and Archaeology

Where: University of Wyoming, Laramie, WY 82071, Ed Auditorium
Event Details:

Recent analyses of ancient human DNA have transformed our understanding of Native Americans’ origins. Roughly 1/3 of the DNA of ‘Ancestral Paleoindians’ reflects the admixture (ca. 15-20,000 years ago), of East Asians with a now-vanished Siberian population, known as ‘Ancient North Eurasians.’ Based on this evidence, all living Native Americans are direct descendants of the Paleoindians who made Clovis tools extending from Montana, where the Anzick infant was buried ca. 12,800 years ago, to Tierra del Fuego. Any earlier peoples, such as the hypothesized ‘seaweed eaters’ of Monte Verde, the ‘rock-bashers’ of Pedra Furada, or the Cerutti ‘mastodon bone-smashers,’ must have been replaced or genetically swamped by Clovis descendants, if they ever existed at all. This genomic evidence allows us to ask; did these ancestral populations move south via the Pacific coast or along the interior ice-free corridor? Was there a long period of isolation in the far north? And why they prevail?
