ABSTRACT

When did humans colonize the Americas? From where did they come and what routes did they take? These questions have gripped
scientists for decades, but until recently answers have proven difficult to find. Current genetic evidence implies dispersal
from a single Siberian population toward the Bering Land Bridge no earlier than about 30,000 years ago (and possibly after
22,000 years ago), then migration from Beringia to the Americas sometime after 16,500 years ago. The archaeological records
of Siberia and Beringia generally support these findings, as do archaeological sites in North and South America dating to
as early as 15,000 years ago. If this is the time of colonization, geological data from western Canada suggest that humans
dispersed along the recently deglaciated Pacific coastline.

    • "The biological variation of Pleistocene–Holocene American populations has been the focus of intense research for more than 150 years (e.g., Chatters et al. 2014; González-José et al. 2008; Hrdlička 1912; Hubbe et al. 2010; Lahr 1996; Lund 1842; Neves and Pucciarelli 1991; Perego et al. 2009; Stringer 1992; Turner 1983). Most of these investigations comprise a wide variety of studies concerning the peopling of the Americas, which have been the subject of continued debates (Goebel et al. 2008; Powell and Neves 1999). The large interest raised by this issue is partially due to the fact that South America was the last continent to be colonized by modern humans (after the Late Glacial Maximum) in association with an apparently fast spread across the region and with relatively high levels of morphological, cultural, and linguistic important because, despite the large morphological variation of the area (Pucciarelli et al. 2010; Sardi et al. 2005), the Southern Cone of South America was one of the latest regions to be inhabited by human populations.

    • "32,000-14,000 14 C yr BP (Bar-Yosef and Kuhn 1999; Collins 2005; Gilead and Bar-Yosef 1993; Smith 1966). Likely humans that arrived in America by any of the currently suggested routes (e.g., Erlandson 2002; Fladmark 1979; Goebel et al. 2008; Miotti 2006; Stanford and Bradley 2012) knew this technology. Although in the oldest sites of South America like Monte Verde, Arroyo Seco, or Piedra Museo, among others, this technology is not recorded. "

    ABSTRACT: This paper presents results of investigation of an early archaeological site in Uruguay, and considers its position on a regional scale. Pay Paso 1 is the first early site of Uruguay to yield both artifacts and faunal remains including records of Pleistocene fauna (Equus sp. and Glyptodon sp.) in a radiocarbon-dated stratigraphic context. From stratigraphic, chronological and archaeological observations, three cultural components for the Pleistocene-Holocene transition have been identified, together representing one of the most intensively AMS dated sites in South America. This solid chronological base allows the positioning of the peopling of Uruguay in the context of the early settlement of the surrounding region including northeastern Argentina and southern Brazil. The site is also remarkable because it yielded evidence of a blade technology at 12,802 cal yr BP, with numerous blades and a depleted blade core, which, together with the records from Laguna Canosa and K87 (Arroyo del Tigre), permit the definition of the Tigre and Pay Paso Paleoamerican cultural complexes. Tigre and Pay Paso bifacial points were produced in post- Fishtail times in the Low Plains, a vast open territory in Uruguay and southern Brazil.
