The evidence for human agency in the late Pleistocene Megafaunal extinctions
Inferring past demographic changes at different spatial scales in Northwest Patagonia and central‐south Chile
In this study, we compare the patterns of demographic changes in populations from Northwest Patagonia and central‐south Chile throughout the Late Pleistocene–Holocene obtained from absolute dates with those resulting from molecular genealogies. We have found that temporal distributions of frequencies of absolute dates constitute a more sensitive demographic indicator than molecular data to make inferences at small spatial scales in the region. Mo…
Prehistoric human diet composition in Northwest Patagonia
In this work, we study diet composition of prehistoric human populations of Northwest Patagonia by exploring the combination of two different approaches frequently used in bioarchaeology, Bayesian isotope mixing models, and zooarchaeological analysis. For this purpose, we compiled a large dataset of previously published δ13C and δ15N human and resource values, as well as zooarchaeological data, corresponding to the Middle-Late Holocene and distri…
Spatio-temporal demographic dynamics of the human populations from Northwest Patagonia and central Chile during the Pleistocene-Holocene
Looking for criteria to define groups and select resources for mixing models in northwest Patagonia. Comments on the paper by Gil et al. (JAS Reports 2020, 34, 102620)
Modelling the Routes of Seasonal Transhumance Movement in North Neuquén (Patagonia)
Hunter-Gatherer Persistence and Demography in Patagonia (Southern South America)
The results of this chapter suggest that hunter-gatherers from northwest and south Patagonia were resilient to the significant ecological changes that took place during the Late Pleistocene and Early Holocene. In particular, the rate of population growth was resistant to reduction in the diversity of available resources as a consequence of megafaunal extinctions around 10 000 BP. The resistance of hunter-gatherers from northwest and south Patagon…
Multidisciplinary studies in Cucurbita maxima (squash) domestication
Mitochondrial-DNA Phylogenetic Information and the Reconstruction of Human Population History
Mitochondrial DNA (mtDNA) sequences are becoming increasingly important in the study of human population history. Here, we explore the diffferences in the amount of information of diffferent mtDNA regions and their utility for the reconstruction of South American population history. We analyzed six data sets comprising 259 mtDNA sequences from South America: Complete mtDNA, Coding, Control, hypervariable region I (HVRI), Control plus cytochrome b…
Estimación de la edad de guanaco (Lama guanicoe) a partir de los dientes incisivos
El guanaco fue el principal recurso para los cazadores-recolectores que habitaron las regiones pampeana y patagónica de Argentina. Este ungulado jugó un rol fundamental en las esferas económica, social e ideológica de estas sociedades durante el Holoceno. En este sentido, comprender la relación entre las poblaciones de humanos y guanacos en el pasado es crucial para la zooarquelogía sudamericana. El objetivo de este trabajo es presentar una metod…
Technical note
OBJECTIVES: One of the biggest challenges in the study of complex morphologies is to adequately describe shape variation. Here, we assess how the random sampling of surface points automatically obtained performs, when compared with observer-guided sampling procedures, and also evaluate the effect of sliding surface points by bending energy and minimum Procrustes distance. MATERIAL AND METHODS: Three datasets comprising structures with disparate l…
Early Holocene Human Remains from the Argentinean Pampas
Morphological comparisons between the earliest and latest human skeletons of America have suggested the existence of a complex scenario underlying the biological diversification of American populations. In the late nineteenth and early twentieth centuries Florentino Ameghino initiated the debate on the antiquity of humans in the Argentinean Pampas, which has been reviewed recently due to new radiocarbon dates obtained. Morphometric analyses from …

Ontogeny of robusticity of craniofacial traits in modern humans
To date, differences in craniofacial robusticity among modern and fossil humans have been primarily addressed by analyzing adult individuals; thus, the developmental basis of such differentiation remains poorly understood. This article aims to analyze the ontogenetic development of craniofacial robusticity in human populations from South America. Geometric morphometric methods were used to describe cranial traits in lateral view by using landmark…
Spatial patterns and evolutionary processes in southern South America
The purpose of this article is to examine the patterns of evolutionary relationships between human populations from the later Late Holocene (1,500–100 years BP) of southern South America on the basis of dental morphometric data. We tested the hypotheses that the variation observed in this region would be explained by the existence of populations with different phylogenetic origin or differential action of gene flow and genetic drift. In this stud…
Early Holocene human remains from the Argentinean Pampas
The cranial morphology of Early Holocene American human samples is characterized by a long and narrow cranial vault, whereas more recent samples exhibit a shorter and wider cranial vault. Two hypotheses have been proposed to account for the morphological differences between early and late‐American samples: (a) the migratory hypothesis that suggests that the morphological variation between early and late American samples was the result of a variab…

The influence of artificial cranial vault deformation on the expression of cranial nonmetric traits
Nonmetric cranial traits have been commonly used in evolutionary relationship studies. They develop during the growth and development of an individual, and for this reason its expression presents different sources of genetic and nongenetic variation. However, the use of these features in evolutionary relationship studies carries the implicit assumption that much of the nonmetric trait variation is essentially genetic. Among the nonheritable facto…
Morphological differentiation of aboriginal human populations from Tierra del Fuego (Patagonia)
This study aims to integrate the craniofacial morphological variation of southern South American populations with the results of mtDNA haplogroup variation, to discuss the South America peopling. Because the causes of morphological differentiation of Fueguian populations are still a controversial subject, the comparison with neutral variation could contribute to elucidate them. Samples of human remains from South America regions were used to anal…
Role of wild plant foods among late Holocene hunter‐gatherers from Central and North Patagonia (South America)
This study evaluates the role of plant foods in the subsistence of hunter‐gatherers that inhabited the Central East, Northwest, and Northeast Patagonia (Argentina) during the late Holocene (ca. 3,000–500 years BP). The goal of the present study is to assess the temporal variation of dental caries ratio and wear rate in skeletal samples to ascertain if the biological information supports the dietary shift toward greater consumption of wild plant f…
Differences between sliding semi‐landmark methods in geometric morphometrics, with an application to human craniofacial and dental variation
Over the last decade, geometric morphometric methods have been applied increasingly to the study of human form. When too few landmarks are available, outlines can be digitized as series of discrete points. The individual points must be slid along a tangential direction so as to remove tangential variation, because contours should be homologous from subject to subject whereas their individual points need not. This variation can be removed by minim…
