It is widely believed that the change from discoidal flake production to prismatic blade-making during the Middle-Upper Paleolithic transition in Europe led to enhanced technological efficiency. Specifically, blade-making is thought to promote higher rates of blank production, more efficient and complete reduction of the parent core, and a large increase in(More)
BACKGROUND Middle Palaeolithic stone artefacts referred to as 'Levallois' have caused considerable debate regarding issues of technological predetermination, cognition and linguistic capacities in extinct hominins. Their association with both Neanderthals and early modern humans has, in particular, fuelled such debate. Yet, controversy exists regarding the(More)
The “North Atlantic Ice-Edge Corridor” hypothesis proposes that sometime during the Last Glacial Maximum, roughly 26,500e19,000 years ago, human populations from southern France and the Iberian Peninsula made their way across the North Atlantic and colonized North America. A key element of that hypothesis is the apparent similarity between(More)
There are a number of purported distinctions between Clovis and Gainey technology. Prominent among these is the lack of overshot flaking in the production of Gainey bifaces. A recent survey of debitage from the Arc site in western New York state suggests that overshot flaking was indeed practiced by Paleoindians in the Lower Great Lakes, suggesting that(More)
BACKGROUND Estimating assemblage species or class richness from samples remains a challenging, but essential, goal. Though a variety of statistical tools for estimating species or class richness have been developed, they are all singly-bounded: assuming only a lower bound of species or classes. Nevertheless there are numerous situations, particularly in the(More)
A long-standing debate in Pleistocene archaeology concerns the sources of variation in the technology of colonizing hunter-gatherers. One prominent example of this debate is Clovis technology (13,350-12,500 calendar years before present), which represents the earliest widespread and currently recognizable remains of hunter-gatherers in North America. Clovis(More)
Paleoindian unifacial stone tools frequently exhibit distinct, sharp projections, known as "spurs". During the last two decades, a theoretically and empirically informed interpretation-based on individual artifact analysis, use-wear, tool-production techniques, and studies of resharpening-suggested that spurs were sometimes created intentionally via(More)
Lohse, Collins, and Bradley ignore or misrepresent the arguments we have made concerning “controlled” overshot flaking and the purported Ice-Age Atlantic Crossing. Here, we summarize our previous work and explain again how it directly tests the explicit claims of Stanford and Bradley (; Bradley and Stanford , ). We also correct the inaccuracies(More)
The weaponry technology associated with Clovis and related Early Paleoindians represents the earliest well-defined evidence of humans in Pleistocene North America. We assess the technological diversity of these fluted stone points found at archaeological sites in the western and eastern halves of North America by employing statistical tools used in the(More)
