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… 

A genomic perspective on South American human history.

The present review aims to create a comprehensive picture of the main events involved in the formation of contemporary South American indigenous populations and the dynamics responsible for shaping their genetic diversity by integrating current genetic data with evidence from archeology, linguistics and other disciplines.

Overview of the Americas’ First Peopling from a Patrilineal Perspective: New Evidence from the Southern Continent

A comprehensive and updated phylogeny of the distinctive Native American branches of haplogroups C and Q is provided and the first Y-chromosome insights into the early peopling of the South American hinterland and on overlying inland migrations are provided.

Indigenous peoples in eastern Brazil: insights from 19th century genomes and metagenomes

Although Brazil was inhabited by more than 3,000 Indigenous populations prior to European colonization, today’s Indigenous peoples represent less than 1% of Brazil’s census population. Some of the

Weaving Mitochondrial DNA and Y-Chromosome Variation in the Panamanian Genetic Canvas

Compared to a new sample collection from 431 individuals belonging to either the general population, mixed groups, or one of five Indigenous groups currently living in Panama, different proportions of paternal and maternal lineages in the Indigenous groups testifying to pre-contact demographic events and genetic inputs that created genetic structure are found.

Insights into human history from the first decade of ancient human genomics

The continued development in the ancient DNA field has transformed the understanding of human genetic history and will keep uncovering the further mysteries of the authors' recent evolutionary past.

A Tale of Native American Whole-Genome Sequencing and Other Technologies

There is a need for more involvement of the home countries as leads in indigenous genomic studies, and it is found that 607 indigenous groups are still missing representation in genomic datasets.

A critical assessment of claims that human footprints in the Lake Otero basin, New Mexico date to the Last Glacial Maximum

The ancient human footprints in valley-bottom sediments in Tularosa Valley, New Mexico, are fascinating and potentially important because they suggest interactions between Pleistocene megafauna as

The immunogenetic impact of European colonization in the Americas

It is shown that post-contact Indigenous immune adaptation, possibly influenced by selection exerted by introduced pathogens, is highly complex and likely to be affected by multifactorial causes, highlighting the need for the implementation of population genetic approaches that model the short time spans and complex demographic histories under consideration.

Morphometric affinities and direct radiocarbon dating of the Toca dos Coqueiros’ skull (Serra da Capivara, Brazil)

The biological variation of the earliest skeletons of South America has been intensely debated for the last two centuries. One of the major research constraints has been the limited number of

A genomic view of the peopling of the americas

Whole genome studies enhanced by technological breakthroughs in ancient DNA now provide evidence of a sequence of events involving initial migration from a structured Northeast Asian source population, followed by a divergence into northern and southern Native American lineages.

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.

Ancient human parallel lineages within North America contributed to a coastal expansion

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.

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’.

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.

Genomic insights into the early peopling of the Caribbean

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.

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.

Ancient mitochondrial DNA provides high-resolution time scale of the peopling of the Americas

The data suggest that a small population entered the Americas via a coastal route around 16.0 ka, following previous isolation in eastern Beringia for ~2.4 to 9 thousand years after separation from eastern Siberian populations.

Ancient individuals from the North American Northwest Coast reveal 10,000 years of regional genetic continuity

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.
