In less than a decade, analyses of ancient genomes have transformed our understanding of the Indigenous peopling and population history of the Americas. These studies have shown that this history, which began in the late Pleistocene epoch and continued episodically into the Holocene epoch, was far more complex than previously thought. It is now evident that the initial dispersal involved the movement from northeast Asia of distinct and previously unknown populations, including some for whom… Expand

Early human dispersals within the Americas
TLDR
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.

A genomic view of the peopling of the Americas.
TLDR
It is shown that during the Holocene, new migrations from Asia introduced the Saqqaq/Dorset Paleoeskimo population to the North American Arctic ∼4500 years ago, ancestry that is potentially connected with ancestry found in Athabaskan-speakers today. Expand
Ancient human parallel lineages within North America contributed to a coastal expansion
TLDR
91 ancient human genomes from California and Southwestern Ontario are presented and the existence of two distinct ancestries in North America is demonstrated and these proportions are consistent with a coastal dispersal and multiple admixture events. Expand
Terminal Pleistocene Alaskan genome reveals first founding population of Native Americans
TLDR
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’. Expand
Genomic insights into the early peopling of the Caribbean
TLDR
Genome-wide data for 93 ancient Caribbean islanders reveals evidence of at least three separate dispersal events into the region, including two early dispersals into the Western Caribbean, one of which seems connected to radiation events in North America. Expand
Genomic evidence for the Pleistocene and recent population history of Native Americans
TLDR
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. Expand
Reconstructing the Deep Population History of Central and South America
TLDR
Genome-wide ancient DNA from 49 individuals forming four parallel time transects in Belize, Brazil, the Central Andes, and the Southern Cone suggests a population replacement that began at least 9,000 years ago and was followed by substantial population continuity in multiple regions. Expand
The population history of northeastern Siberia since the Pleistocene
TLDR
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. Expand
Ancient individuals from the North American Northwest Coast reveal 10,000 years of regional genetic continuity
TLDR
It is concluded from individuals sampled through time that people of the northern Northwest Coast belong to an early genetic lineage that may stem from a late Pleistocene coastal migration into the Americas. Expand
Ancient Genomics of Modern Humans: The First Decade.
TLDR
New insights based on prehistoric modern human genomes are reviewed, including greatly increased resolution of the timing and structure of the out-of-Africa expansion, the diversification of present-day non-African populations, and the earliest expansions of those populations into Eurasia and America.
