The Late Pleistocene Dispersal of Modern Humans in the Americas
Ted Goebel,Ted Goebel,Michael R. Waters,Michael R. Waters,Dennis H. O'Rourke,Dennis H. O'Rourke +5 more
TL;DR: Current genetic evidence implies dispersal from a single Siberian population toward the Bering Land Bridge no earlier than about 30,000 years ago, then migration from Beringia to the Americas sometime after 16,500 years ago.

TL;DR: In this paper, the authors present genome-wide sequence data from ancient and present-day humans from Greenland, Arctic Canada, Alaska, Aleutian Islands, and Siberia, and show that a single Paleo-Eskimo metapopulation likely survived in near-isolation for more than 4000 years, only to vanish around 700 years ago.
Journal ArticleDOI
The Human Genetic History of the Americas: The Final Frontier
Dennis H. O'Rourke,Jennifer Raff +1 more
TL;DR: Rapidly accumulating molecular data from populations throughout the Americas, increased use of demographic models to test alternative colonization scenarios, and evaluation of the concordance of archaeological, paleoenvironmental and genetic data provide optimism for a fuller understanding of the initial colonization of the Americas.
Journal ArticleDOI
Ancient DNA Studies in Physical Anthropology
TL;DR: The analysis of ancient (a)DNA is complicated by the degraded nature of ancient nucleic acids, as well as the presence of enzymatic inhibitors in aDNA extracts as mentioned in this paper.
Journal Article
Refutation of the general single-locus model for the etiology of schizophrenia.
TL;DR: The single major locus model is inadequate to predict the incidence in four classes of relatives of schizophrenic probands (parents, siblings, monozygotic, and dizygotic cotwins) and the observed proportion of affected offspring from dual matings differ significantly from the model's prediction.
