Upward Sun River 1, an individual from a unique burial of the Denali tradition in Alaska (11500 calBP), is considered a type representative of Ancient Beringians who split from other First Americans 22000–18000 calBP in Beringia. Using a new admixture graph model-comparison approach resistant to overfitting, we show that Ancient Beringians do not form the deepest American lineage, but instead harbor ancestry from a lineage more closely related to northern North Americans than to southern North… 
ABSTRACT The study of the peopling of the Americas has been transformed in the past decade by astonishing progress in paleogenomic research. Ancient genomes now show that Native American ancestors
Deep genetic affinity between coastal Pacific and Amazonian natives evidenced by Australasian ancestry
It is demonstrated that the Australasian genetic signal is present in the Pacific coast region, indicating a more widespread signal distribution within South America and implicating an ancient contact between Pacific and Amazonian dwellers.
Indian genetic heritage in Southeast Asian populations
The finding suggests that a massive migration of Indian people in the past was responsible for the spread of Indian culture in mainland Southeast Asia, and support for a close genetic affinity between Kra-Dai- and Austronesianspeaking populations, which fits a linguistic hypothesis suggesting cladality of the two language families.
Peopling the Americas: Not “Out of Japan”
ABSTRACT A widely accepted model for the peopling of the Americas postulates a source population in the Northeast Asian maritime region, which includes northern Japan. The model is based on
Dental Morphology of Naia, a Late Pleistocene Human from Mexico and the Sinodont/Sundadont Issue
ABSTRACT The dental morphology of the earliest Americans is poorly known, partly because existing data are largely unpublished and partly because dental wear is typically extreme in the few complete
Circumpolar peoples and their languages: lexical and genomic data suggest ancient Chukotko-Kamchatkan–Nivkh and Yukaghir-Samoyedic connections
A weighted permutation test was developed and applied to basic vocabularies of a number of languages and reconstructed proto-languages to show that at least three groups of circumpolar language families in the Northern Hemisphere show evidence of relationship though borrowing in the basic vocabulary or common descent.
Indian genetic heritage in Southeast Asian populations 1 2
The results obtained allowed us to assess the importance of knowing the carrier and removal status of canine coronavirus, as a source of infection for other animals, not necessarily belonging to the same breeds.


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.
Ancient genomes document multiple waves of migration in Southeast Asian prehistory
Ancient migrations in Southeast Asia The past movements and peopling of Southeast Asia have been poorly represented in ancient DNA studies (see the Perspective by Bellwood). Lipson et al. generated
Ancient DNA indicates human population shifts and admixture in northern and southern China
Genetic differentiation in this region was higher in the past than the present, which reflects a major episode of admixture involving northern East Asian ancestry spreading across southern East Asia after the Neolithic, thereby transforming the genetic ancestry of southern China.
A Working Model of the Deep Relationships of Diverse Modern Human Genetic Lineages Outside of Africa
A model that provides a good statistical fit to allele-frequency correlation patterns among East Asians, Australasians, Native Americans, and ancient western and northern Eurasians, together with archaic human groups is reported, providing a useful summary of deep Eurasian population history.
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’.
The prehistoric peopling of Southeast Asia
Neither interpretation fits the complexity of Southeast Asian history: Both Hòabìnhian hunter-gatherers and East Asian farmers contributed to current Southeast Asian diversity, with further migrations affecting island SEA and Vietnam.
Ancient genomes from northern China suggest links between subsistence changes and human migration
55 ancient genomes from the YR, WLR, and Amur River regions are presented to suggest a link between changes in subsistence strategy and human migration, and fuel the debate about archaeolinguistic signatures of past human migration.
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.
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.
