“…These results, together with the rest of the archaeological record, encourage further studies on regional biological diversity. Unfortunately, the high levels of soil organic matter and moisture surrounding the skeletal remains make molecular genetic studies difficult (Cardozo et al, 2021). Although work continues on their extraction in a small sample, these studies are destructive and costly to perform on large sample sizes.…”

Introduction This study assesses the biological affinity between Late Holocene hunter‐gatherers that inhabited the region of the lower Paraná wetland (Argentina) at the end of the Late Holocene (1800–700 years BP). Methods Cranial nonmetric traits were registered in 159 adult individuals of both sexes. Biodistances were estimated between environmental and archaeological units through Smith's Mean Measure of Divergence, Mahalanobis distance, multidimensional scaling, Fst index, and R‐matrix. Biological distances concerning temporal and geographic distances between the archaeological sites were also evaluated through Mantel and partial Mantel tests. Results The environmental units showed statistically significant biodistances according to a distance spatial pattern but low genetic differentiation between groups. Additionally, some archaeological sites with median radiocarbon dates around 700 years BP also presented statistically significant biodistances. Conclusions Gene flow and genetic drift could be responsible for the observed biodistance results. These processes gave rise to different subpopulations of hunter‐gatherers with a shared material culture, whose territorial limits could have been reinforced around 700 years BP or earlier.

“…As a result, the involvement of South American researchers in ancient DNA (aDNA) studies is frequently subordinated to the research agenda of the nonlocal laboratories. This situation discourages the pursuit of locally relevant research objectives that often involve more restricted time or spatial scales (Arencibia et al 2019;Cardozo et al 2021;Crespo et al 2020;Motti et al 2020;Postillone et al 2020;Russo et al 2016Russo et al , 2018Tavella et al 2020). The development of such asymmetrical relationships is common to many scientific fields that depend on costly technological development; this "subordinate integration" (Kreimer 2006;Kreimer and Ugartemendía 2007) is a recurring phenomenon in the global division of scientific labor today.…”

Ancient Human Mitogenome of the Beagle Channel (Tierra del Fuego): An Argentine Collaborative Project

The increasing use of massively parallel sequencing in the study of current and ancient human populations has enabled new approaches to bioanthropological and archaeological issues; however, its application to archaeological samples requires the use of technologies that are not easily accessible outside US and European research centers. To obtain an ancient mitogenome in Argentina, several institutions collaborated to apply massively parallel sequencing and bioinformatic methodologies on an enriched ancient DNA library of an individual from the Beagle Channel (dated 1504 ± 46 years BP), a region of particular interest for this line of inquiry. Phylogenetic reconstruction showed a close relationship with a Yamana from Navarino Island and an individual from Hoste Island (Chilean Antarctic Province): the three shared an ancestor who lived between 203 and 4,439 years ago. These three have mutations reported only for current and ancient individuals from the Beagle Channel, and their relationship with the rest of the D1g sub-haplogroups is unclear. The results obtained here are consistent with the reduction of mobility in the Fuegian archipelago around 4500 years BP that has been proposed based on archaeological evidence.

Durante el periodo prehispánico tardío, la región del Paraná medio e inferior se caracterizó por la coexistencia de diferentes grupos con estrategias económicas basadas tanto en la caza, recolección y pesca como en la horticultura. A partir de la colonización española, la instalación de reducciones desestructuró los modos de vida de las poblaciones nativas y en particular de aquellos individuos que fueron incorporados para sostener tales instituciones. El consumo de alimentos no fue ajeno a estos cambios, tal como lo demuestran las fuentes documentales. En el presente trabajo se examina la dieta de individuos que vivieron en la reducción Santiago del Baradero (Provincia de Buenos Aires) a través del análisis de isótopos estables de carbono y nitrógeno (δ13C, δ15N) y la comparación con los datos relevados por otros investigadores para momentos prehispánicos. En función de ello se realizaron mediciones isotópicas sobre los alimentos que podrían haber sido consumidos en la reducción, según la información que refieren los documentos del Archivo General de Indias. Los resultados indican una mayor dependencia de alimentos caracterizados por un patrón fotosintético C4, similar a la de los grupos horticultores prehispánicos, y un menor consumo de proteínas hacia los últimos años de sus vidas, en algunos de los individuos.
