Upper Palaeolithic Siberian genome reveals dual ancestry of Native Americans
The findings reveal that western Eurasian genetic signatures in modern-day Native Americans derive not only from post-Columbian admixture, as commonly thought, but also from a mixed ancestry of the First Americans.
Genetic Discontinuity Between Local Hunter-Gatherers and Central Europe’s First Farmers
Together, these analyses provide persuasive evidence that the first farmers were not the descendants of local hunter-gatherers but immigrated into central Europe at the onset of the Neolithic.
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 recent bottleneck of Y chromosome diversity coincides with a global change in culture.
A study of 456 geographically diverse high-coverage Y chromosome sequences, including 299 newly reported samples, infer a second strong bottleneck in Y-chromosome lineages dating to the last 10 ky, and hypothesize that this bottleneck is caused by cultural changes affecting variance of reproductive success among males.
A signal, from human mtDNA, of postglacial recolonization in Europe.
The present study shows that the dissection of mtDNA variation into small and well-defined evolutionary units is an essential step in the identification of spatial frequency patterns, and promises to be an efficient strategy for inferring features of human prehistory.
Genomic Diversity and Admixture Differs for Stone-Age Scandinavian Foragers and Farmers
Hunters and Farmers The Neolithic period in Europe saw the transition from a hunter-gatherer lifestyle to farming. Previous genetic analyses have suggested that hunter-gatherers were replaced by
Origin and expansion of haplogroup H, the dominant human mitochondrial DNA lineage in West Eurasia: the Near Eastern and Caucasian perspective.
The phylogeography of hg H in the populations of the Near East and the Caucasus is described, showing how most of the present-day Near Eastern-Caucasus area variants of hG H started to expand after the last glacial maximum (LGM) and presumably before the Holocene.
Genomic analyses inform on migration events during the peopling of Eurasia
A genetic signature in present-day Papuans that suggests that at least 2% of their genome originates from an early and largely extinct expansion of anatomically modern humans (AMHs) out of Africa earlier than 75,000 years ago is found.
The western and eastern roots of the Saami--the story of genetic "outliers" told by mitochondrial DNA and Y chromosomes.
A high-resolution phylogenetic analysis of Saami genetic heritage was undertaken in a comprehensive context, through use of maternally inherited mitochondrial DNA (mtDNA) and paternALLY inherited Y-chromosomal variation, and it was shown that the "Saami motif" variant of mtDNA haplogroup U5b is present in a large area outside Scandinavia.
