The Puzzles of the First American Immigration | Adventure Diffusion
Who were the first Americans, where did they come from and how did they spread? The story is as thrilling as an adventure story—in fact, it is one.
Place: North America
Analysis of the human Y-chromosome haplogroup Q characterizes ancient population movements in Eurasia and the Americas
To assess the timing, places of origin and extent of admixture between these components, we performed an analysis of the Y-chromosome haplogroup Q, which is the only Pan-American haplogroup and accounts for virtually all Native American Y chromosomes in Mesoamerica and South America.
How strong was the bottleneck associated to the peopling of the Americas? New insights from multilocus sequence data
In spite of many genetic studies that contributed for a deep knowledge about the peopling of the Americas, no consensus has emerged about important parameters such as the effective size of the Native Americans founder population.
Terminal Pleistocene Alaskan genome reveals first founding population of Native Americans
The remains of two infants were recovered at Upward Sun River (USR), and have been dated to around 11.5 thousand years ago (ka)6.
Genetic studies of the peopling of the Americas: What insights do diachronic mitochondrial genome datasets provide?
Here we briefly review the evidence for current hypotheses on the peopling process of the Americas and discuss how ancient mitochondrial DNA can provide a unique temporal perspective.
Genetic structure of First Nation communities in the Pacific Northwest
This study presents genetic data for nine Native American populations from northern North America. Analyses of genetic variation focus on the Pacific Northwest (PNW).
Ancient individuals from the North American Northwest Coast reveal 10,000 years of regional genetic continuity
We present genome-wide sequences of individuals from the northern Northwest Coast covering a timespan of ∼10,000 years and show that continental patterns of demography do not necessarily apply on the regional level.
A time transect of exomes from a Native American population before and after European contact
To investigate whether a pre-existing genetic component contributed to this phenomenon, here we analyse 50 exomes of a continuous population from the Northwest Coast of North America, dating from before and after European contact.
A continuum of admixture in the Western Hemisphere revealed by the African Diaspora genome
Here we present genetic variation from deeply sequenced genomes of 642 individuals from North and South American, Caribbean and West African populations, substantially increasing the lexicon of human genomic variation and suggesting much variation remains to be discovered in African-admixed populations in the Americas.
Postglacial viability and colonization in North America’s ice-free corridor
Our 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.
