The peopling of the Americas marks a major expansion of humans across the planet. However, questions regarding the timing and mechanisms of this dispersal remain, and the previously accepted model (termed ‘Clovis-first’)—suggesting that the first inhabitants of the Americas were linked with the Clovis tradition, a complex marked by distinctive fluted lithic points 1 —has been effectively refuted. Here we analyse chronometric data from 42 North American and Beringian archaeological sites using a… 

Evidence of humans in North America during the Last Glacial Maximum

In situ fossil footprints show that humans were present in North America between ~23,000 and 21,000 years ago during the Last Glacial Maximum, adding evidence to the antiquity of human colonization of the Americas and providing a temporal range extension for the coexistence of early inhabitants and Pleistocene megafauna.

Archaeological evidence shows widespread human depopulation of Last Glacial Maximum Northeast Asia

For decades, archaeologists have debated whether Paleolithic humans withdrew from Northeast Asia during the Last Glacial Maximum (LGM), an issue especially important for the Pleistocene peopling of

Human Occupation of the North American Colorado Plateau ∼37,000 Years Ago

Calibrating human population dispersals across Earth’s surface is fundamental to assessing rates and timing of anthropogenic impacts and distinguishing ecological phenomena influenced by humans from

Demography and evolutionary history of grey wolf populations around the Bering Strait

Glacial and interglacial periods throughout the Pleistocene have been substantial drivers of change in species distributions. Earlier analyses suggested that modern grey wolves (Canis lupus) trace

Climate and mountains shaped human ancestral genetic lineages

The authors' reconstructions show that the sharp separation between African and Eurasian lineages is a consequence of only a few limited periods of connectivity through the arid Arabian peninsula, which acted as the gate out of the Arican continent, leading to the split of European and Asians and the further diversification of these two groups.

Current Understanding of the Earliest Human Occupations in the Americas: Evaluation of Becerra-Valdivia and Higham (2020)

ABSTRACT Various chronologies of the earliest Native American occupations have been proposed with varying levels of empirical support and conceptual rigor, yet none is widely accepted. A recent

The Chiquihuite Cave, a Real Novelty? Observations about the Still-ignored South American Prehistory

ABSTRACT The recently reported discovery of cultural evidence at Chiquihuite Cave (Zacatecas, Mexico), produced by humans of at least 26,500 calendar years ago, is a major advance in research into

Bayesian Modeling of the Clovis and Folsom Radiocarbon Records Indicates a 200-Year Multigenerational Transition

An enduring problem in North American archaeology concerns the nature of the transition between the Clovis and Folsom Paleoindian complexes in the West. Traditional models indicate a temporal hiatus

Ancient DNA Studies in Pre-Columbian Mesoamerica

How aDNA research has helped discern population dynamics patterns in the pre-Columbian Mesoamerican context is reviewed, how it supports archaeological, linguistic, and anthropological conclusions, and how it offers new working hypotheses are reviewed.



Evidence of human occupation in Mexico around the Last Glacial Maximum

Results of recent excavations at Chiquihuite Cave provide new evidence for the antiquity of humans in the Americas, illustrate the cultural diversity of the earliest dispersal groups (which predate those of the Clovis culture) and open new directions of research.

Deglaciation of the Pacific coastal corridor directly preceded the human colonization of the Americas

It is concluded that CIS retreat ensured that an open and ecologically viable pathway through southeastern Alaska was available after 17 ka ago, which may have been traversed by early humans as they colonized the Americas.

Early human dispersals within the Americas

Analysis of the oldest genomes suggests that there was an early split within Beringian populations, giving rise to the Northern and Southern lineages, and that the early population spread widely and rapidly suggests that their access to large portions of the hemisphere was essentially unrestricted, yet there are genomic and archaeological hints of an earlier human presence.

Ancient mitochondrial DNA provides high-resolution time scale of the peopling of the Americas

The data suggest that a small population entered the Americas via a coastal route around 16.0 ka, following previous isolation in eastern Beringia for ~2.4 to 9 thousand years after separation from eastern Siberian populations.

Bison phylogeography constrains dispersal and viability of the Ice Free Corridor in western Canada

The chronology supports a habitable and traversable corridor by at least 13,000 cal y BP, just before the first appearance of Clovis technology in interior North America, and indicates that the corridor would not have been available for significantly earlier southward human dispersal.

The Upper Paleolithic of the Americas

ABSTRACT Substantial archaeological and genetic data suggest that the initial occupation of the Americas is more complex and diverse than previously thought. As evidence for multiple patterns and/or

Postglacial viability and colonization in North America’s ice-free corridor

The 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.

Finding the first Americans

Recent work along the Pacific coastlines of North and South America has revealed that these environments were settled early and continuously provided a rich diversity of subsistence options and technological resources for New World hunter-gatherers.

Test of Martin’s overkill hypothesis using radiocarbon dates on extinct megafauna

The hypothesis that the timing of human arrival to the New World can be assessed by examining the ecological impacts of a small population of people on extinct Pleistocene megafauna is proposed and results suggest north to south, time, and space transgressive declines in megafaunal populations as predicted by the overkill hypothesis.
