“…This change in the archaeological record precedes a proposed population replacement in parts of South America starting around 9 kya ( Posth et al., 2018 ). While a different local retraction process and a population replacement in the Middle Holocene (∼8–4 kya), concretely in the latest period, have been proposed based on differences in skull morphology as well as a gap in the radiocarbon database ( Barrientos and Perez, 2005 ), genetic evidence and more dates from archaeological sites indicate population continuity in the region since the Early Holocene ( Politis, 2008 ; Mazzanti et al., 2015 ; Posth et al., 2018 ; Donadei, 2019 ). During the Late Holocene (<4 kya), the complexity of human populations in the Pampas increased due to the introduction of pottery most likely from the subtropical lowlands as well as the development of newly derived technologies from the bow and arrow adoption ( Politis, 2008 ).…”

Summary The Southern Cone of South America (SCSA) is a key region for investigations about the peopling of the Americas. However, little is known about the eastern sector, the Argentinian Pampas. We analyzed 18 mitochondrial genomes—7 of which are novel—from human skeletal remains from 3 Early to Late Holocene archaeological sites. The Pampas present a distinctive genetic makeup compared to other Middle to Late Holocene pre-Columbian SCSA populations. We also report the earliest individuals carrying SCSA-specific mitochondrial haplogroups D1j and D1g from Early and Middle Holocene, respectively. Using these deep calibration time points in Bayesian phylogenetic reconstructions, we suggest that the first settlers of the Pampas were part of a single and rapid dispersal ∼15,600 years ago. Finally, we propose that present-day genetic differences between the Pampas and the rest of the SCSA are due to founder effects, genetic drift, and a partial population replacement ∼9,000 years ago.

“…Las OGSB fueron las rocas más utilizadas para la talla en la Región Pampeana desde el Pleistoceno final, aunque su representación en las distintas áreas varía (i.e., Barros y Messineo, 2006;Bayón, Flegenheimer y Pupio, 2006;Bonomo, 2005;Flegenheimer, Mazzia y Weitzel, 2015;González, 2005;Martínez, 2006;Mazzanti et al 2015; entre muchos otros). En términos generales, para el Holoceno medio se propone un uso del espacio que combina movimientos residenciales y logísticos, con ocupaciones breves (Martínez, 2006) y la elección de una estrategia de abastecimiento de individuos, con el consecuente traslado de formas base, instrumentos terminados y en ciertas ocasiones, pequeños núcleos preparados de OGSB hacia los sitios receptores (Barros et al, 2014;Donadei, 2019;Martínez, 2006). Las características de los núcleos y de los módulos de lascas e instrumentos registradas en el Alero La Esperanza son similares a las observadas, para el mismo periodo, en sitios alejados de las fuentes (Barros et al, 2014).…”

Asimismo, el hecho de que este taller presente los momentos intermedios de la cadena operativa es consistente con una tecnología de obtención de lascas, por percusión directa para el abastecimiento de formas base e instrumentos terminados de estos sitios receptores (i.e., Barros et al, 2014;Donadei, 2019;Mazzanti et al, 2015).…”

Se presentan los resultados del análisis de los materiales líticos recuperados en el sitio Alero La Esperanza (La Numancia, Pdo. de Tandil, Región Pampeana). Se trata de un taller ubicado en inmediaciones de canteras-taller de ortocuarcita grupo Sierras Bayas, datado en el Holoceno medio. Los resultados indican que en este espacio se llevaron a cabo las etapas intermedias de la cadena operativa y los objetivos de producción son consistentes con las propuestas de aprovechamiento de las ortocuarcitas del grupo Sierras Bayas durante el Holoceno medio.

“…4200 cal years BP), a stronger emphasis in terrestrial mammals has been proposed, and some researchers have suggested a specialization in ungulate hunting (Quintana and Mazzanti 2001;Martínez and Gutiérrez 2004;Álvarez 2014). Regarding the lithic technology, orthoquartzite was the preferred raw material for tool production (Martínez 2002;Barros et al 2018;Donadei 2019). Medium-sized triangular projectile points and bola stones were the basic hunting tools, while unifacial tools, mainly side and end scrapers, were the more common processing tools (Politis 2008;Donadei 2019).…”

Despite a long history of hunter-gatherer occupation in the Pampas region starting at the end of the Pleistocene, the known archaeological record is still sparse for some periods, such as the Middle Holocene. Here, we present new archaeological data from Las Toscas shallow lake, located in the inland plains of the southern Pampas, where systematic fieldwork revealed an abundant and diverse archaeological record resulting from hunter-gatherer occupation. The aims of this study were to establish the chronology of the occupations; to evaluate the use of faunal and lithic resources; and to contribute to the understanding of hunter-gatherer land use patterns. Archaeological evidence indicates that procurement, domestic, and ritual activities were conducted around the shallow lake during the Middle and Late Holocene, including hunting of terrestrial game; tool manufacture and repair; storing and use of mineral pigments; and likely human burial practices. Evidence also suggests that the use of this locality was not continuous but redundant and that this shallow lake was a persistent place for hunter-gatherers. Faunal data agrees with regional models that propose that Lama guanicoe was the main food resource during the second half of the Middle Holocene, although a taphonomic bias in favor of larger vertebrates cannot be ruled out. The lithic assemblages suggest that artifacts entered the locality mostly as part of individual toolkits and indicate a strong preference for orthoquartzite. Finally, bone remains of extinct fauna were recovered at the locality; however, a functional association between these remains and cultural material could not be demonstrated.
