The timing of human entrance into North America has been a topic of debate that dates back to the late 19th century. Central to the modern discussion is not whether late Pleistocene-age populations were present on the continent, but the timing of their arrival. Key to the debate is the age of tools—bone rods, large prismatic stone blades, and bifacially chipped and fluted stone weapon tips—often found associated with the remains of late Pleistocene fauna. For decades, it was assumed that this…

Paleoamerican Occupation, Stone Tools from the Cueva del Medio, and Considerations for the Late Pleistocene Archaeology in Southern South America

Archaeological excavations at the Cueva del Medio performed during the 1980s and 1990s yielded an important record of both faunal and stone tool remains, as well as data, to discuss issues that

Forty years ago, Knut Fladmark (1979) argued that the Pacific Coast offered a viable alternative to the ice-free corridor model for the initial peopling of the Americas—one of the first to support a

ABSTRACT The Clovis techno-complex has figured prominently in American archaeology since the 1930s, when fluted stone weapon tips and other tools were found alongside the remains of late Pleistocene

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.

Why we're still arguing about the Pleistocene occupation of the Americas

The now classic and probably incorrect story of New World colonization begins in Late Pleistocene Siberia, with small a population of foragers migrating across Beringia through an ice‐free corridor and traveling through the interior of North America.

Origins and spread of fluted-point technology in the Canadian Ice-Free Corridor and eastern Beringia

Results link morphologies and technologies of Clovis, certain western Canadian, and northern fluted points, suggesting that fluting technology arrived in the Arctic from a proximate source in the interior Ice-Free Corridor and ultimately from the earliest populations in temperate North America, complementing new genomic models explaining the peopling of the Americas.

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.

Beringia and the global dispersal of modern humans

The settlement of Beringia now appears to have been part of modern human dispersal in northern Eurasia, and developments suggest that the settlement of the Americas may be integrated with the global dispersal of modern humans.

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.

Early Human Settlement of Northeastern North America
