This article synthesizes the 2000s-era “peopling of the Americas” data drawn from molecular biology, osteology, and archaeology. Collectively, they suggest that colonization proceeded in two pulses, both originating in western Beringia, and before that, south-central and southeastern Siberia. The first pulse occurred circa 16 k–15 k cal. B.P. by watercraft along the coast of Beringia and western North and South America. The second took place 1,000 years later and involved proto-Clovis hunter… 
Early Asiatic Migration to the Americas: A View from South America
During last three decades, American archaeology has generated a large body of information, which has fuelled debate on the early peopling of the New World. This has allowed scientists to propose and

Abstract A substantial amount of archaeological data suggests groups with markedly different lithic technologies and subsistence adaptations were widespread throughout both American continents by
Morphological variation among late holocene Mexicans: Implications for discussions about the human occupation of the Americas.
The results show that the Mexican series share morphological affinities with the East Asian series, but maintains high levels of between-group variation, similar to South America, which supports the suggestion that the high phenotypic variation seen the Americas is not a result of its size, as it can be found in more constricted areas, such as the Mexican territory.
Waterfowl and Lunate Crescents in Western North America: The Archaeology of the Pacific Flyway
California and Great Basin archaeologists have long discussed and debated the function of chipped stone crescents found in Terminal Pleistocene and Early Holocene sites in the Far West of North

Stemmed Points, the Coastal Migration Theory, and the Peopling of the Americas
The flooding of our world’s continental shelves over the last 20,000 years has severely limited our ability to reconstruct human migrations and settlements along New and Old World Pleistocene
Spatiotemporal distribution of Holocene populations in North America
The first maps to the authors' knowledge of spatiotemporal paleodemographic growth following human migration into the Americas for the past 13,000 y are provided, using a statistical approach that simultaneously addresses sampling and taphonomic biases.

Towards an interdisciplinary perspective for the study of human expansions and biocultural diversity in the Americas
The timing and mode(s) of the initial human occupation of the Americas are among the most discussed topics in archaeology and biological anthropology, with hundreds of articles published in the last


The Settlement of the American Continents: A Multidisciplinary Approach to Human Biogeography
When many scholars are asked about early human settlement in the Americas, they might point to a handful of archaeological sites as evidence. Yet the process was not a simple one, and today there is
The Peopling of the New World: Present Evidence, New Theories, and Future Directions
The prevailing archaeological consensus on Paleoindian origins and colonization of the Americas has been shaken by recent wide acknowledgment of pre-Clovis occupation at Monte Verde, Chile, and by
Paleoindian Colonization of the Americas: Implications from an Examination of Physiography, Demography, and Artifact Distribution
Abstract GIS-based, least-cost analyses employing continental scale elevation data, coupled with information on the late glacial location of ice sheets and pluvial lakes, suggest possible movement

The Peopling of the New World: Perspectives from Molecular Anthropology
▪ Abstract A number of important insights into the peopling of the New World have been gained through molecular genetic studies of Siberian and Native American populations. These data indicate that
The Late Pleistocene Dispersal of Modern Humans in the Americas
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.
