Sex Differences in Bilateral Asymmetry Among Hunter‐Gatherers From the Lower Paraná River Wetlands (Argentina)
Exploring dental macrowear in a Sambaqui population from Encosta da Lagoa (southern Brazil)
ZooMS Analysis of Archaeological Bone Tools From the South American Lowlands in the Paraná Basin
During the Late Holocene, hunter‐gatherers in the Lower Paraná wetland crafted a wide variety of bone tools. Although traditionally assumed as standardized, recently we found certain morphological, stylistic, and technological variability. Traditional taxonomic identifications based on morphology identified mainly the use of local deer species, but also camelids from the Pampas and non‐dietary carnivore species were detected as secondary bone mat…
Esferoides líticos atípicos entre grupos de cazadores-recolectores de laregiónpampeana
3Artifacts made from non-local raw materials, some of which may have held symbolic value, havebeen recovered in various areas and archaeological sites of the Pampaean region associated withhunter-gatherer groups. Their presence has been interpreted as theresult of processes thatdeveloped especially during theLate Holocene, including the formation of extensive alliancenetworks, an intensification of social interaction, and long-distance exchange o…

Osseous harpoon heads of hunter‐gatherers from the lower Paraná wetland
Harpoons are part of the composite technologies, widely dispersed throughout the world. In South America, a unique type of throwing harpoon reveals a limited distribution, primarily discovered in hunter‐gatherer archaeological sites within the lower La Plata basin. Specifically, they are found in two archaeological units named Incised Pottery and Plain Pottery which are defined by different material properties but share several common aspects as …
Projectile Point Stem Repairs
This study explores the reworking of projectile point stems by hunter-gatherers in southeastern South America. Techniques employed to rework stems included pressure and percussion flaking and, eventually, light abrasion of fractured sections, methods that were applied opportunistically to resolve various types of stem fractures. Although the local literature has often overlooked the presence of reworked stems, it appears that point rebasing was a…

Fishtail Projectile Points from South America
The projectile points known as Fishtail or Fell represent a specific design associated with the earliest hunter-gatherers of the Pleistocene-Holocene transition in South America. Brazil was traditionally considered as a marginal area of their distribution because in the past there were only a small number of findings known, often inadequately documented. In this paper we present a general and unified overview of the Brazilian record, including pr…

Hunter-gatherer Mobility Analysed Through δ 18 O in the Patchy Environment of the Paraná Valley, South American Lowlands
In this study we analyse the mobility of complex hunter-gatherers in the Lower Paraná wetland (South America) through δ18O values. To do this, we characterise the isotopic composition of water and bioapatite of stenoic and sedentary species from the region and the surrounding Pampa plain, and then we compare them with those obtained in human bones recovered at local archaeological sites. The results show that humans appear to have developed spati…
From the Atlantic coast to the lowland forests
In this study, we analyze the diet of forager-horticulturalist societies of southeast South America through different isotopic markers (δ13Ccollagen, δ13Capatite, and δ15N). The economy of these populations was based on hunting, fishing, gathering, and, to a greater or lesser extent, horticulture, showing a different emphasis on each one of these options. The samples analyzed here were recovered from different environments, including the Atlantic…

Complete Mitochondrial Genomes of Ancient Canids Suggest a European Origin of Domestic Dogs
Dog Domestication The precise details of the domestication and origins of domestic dogs are unclear. Thalmann et al. (p. 871 ; see the cover) analyzed complete mitochondrial genomes from present-day dogs and wolves, as well as 18 fossil canids dating from 1000 to 36,000 years ago from the Old and New Worlds. The data suggest that an ancient, now extinct, central European population of wolves was directly ancestral to domestic dogs. Furthermore, s…
