The genome of a Late Pleistocene human from a Clovis burial site in western Montana
The genome sequence of a male infant recovered from the Anzick burial site in western Montana is sequenced and it is shown that the gene flow from the Siberian Upper Palaeolithic Mal’ta population into Native American ancestors is also shared by the AnZick-1 individual and thus happened before 12,600 years bp.
Genomic evidence for the Pleistocene and recent population history of Native Americans
The results suggest that there has been gene flow between some Native Americans from both North and South America and groups related to East Asians and Australo-Melanesians, the latter possibly through an East Asian route that might have included ancestors of modern Aleutian Islanders.
A requiem for North American overkill
Postglacial viability and colonization in North America’s ice-free corridor
The findings reveal that the first Americans, whether Clovis or earlier groups in unglaciated North America before 12.6 cal. kyr bp, are unlikely to have travelled by this route into the Americas, however, later groups may have used this north–south passageway.
Early human dispersals within the Americas
Analysis of the oldest genomes suggests that there was an early split within Beringian populations, giving rise to the Northern and Southern lineages, and that the early population spread widely and rapidly suggests that their access to large portions of the hemisphere was essentially unrestricted, yet there are genomic and archaeological hints of an earlier human presence.
The population history of northeastern Siberia since the Pleistocene
Analysis of 34 newly recovered ancient genomes from northeastern Siberia reveal at least three major migration events in the late Pleistocene population history of the region, including an initial peopling by a previously unknown Palaeolithic population of ‘Ancient North Siberians’ and a Holocene migration of other East Asian-related peoples, which generated the mosaic genetic make-up of contemporary peoples.
Clovis Hunting and Large Mammal Extinction: A Critical Review of the Evidence
The North American archaeological phenomenon known as Clovis is famous for the fact that a number of sites that contain diagnostic Clovis artifacts also contain the remains of mammoth and perhaps…

Abstract The climate of the Great Plains during the middle Holocene varied considerably, but overall it was marked by a north–south gradient of increasingly warmer and drier conditions, with a…
On the Pleistocene Antiquity of Monte Verde, Southern Chile
The potential importance of the Monte Verde site for the peopling of the New World prompted a detailed examination of the collections from that locality, as well as a site visit in January 1997 by a…
Terminal Pleistocene Alaskan genome reveals first founding population of Native Americans
The results suggest that the far-northern North American presence of northern Native Americans is from a back migration that replaced or absorbed the initial founding population of Ancient Beringians, and support a long-term genetic structure in ancestral Native Americans, consistent with the Beringian ‘standstill model’.
