Integrating ancient DNA, stable isotopes, and species distribution models to reconstruct guanaco population history
From the arid core to the Atlantic coast of North Patagonia
Human-araucaria interactions during the Holocene in northwest Patagonia, Argentina
Araucaria araucana has long had an important role in the subsistence and cultural practices of aboriginal groups on both sides of the Andes in Southern South America. Despite its relevance, systematic studies on past human interactions with this species, which is limited to the Pehuén Forest, are lacking. This study examines the spatial pattern of A. araucana use in Northwest Patagonia from the Early Holocene to historic times, comparing it with …
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…

Modelling the Routes of Seasonal Transhumance Movement in North Neuquén (Patagonia)
Summer Camps Location and Distribution of Archaeological Sites in North Neuquén (Northwest Patagonia)
We study the bioclimatic and landscape characteristics of summer camps of modern transhumant herders from North Neuquén to generate a distribution model of upland areas suitable for herding and project their spatial distribution throughout the Holocene. With this aim, we analyzed ethnographic, bioclimatic and landscape data using habitat suitability models. The location of different types of archaeological sites was then compared with the project…

Mobility of human populations in the Curi Leuvú basin, Northwest Patagonia, during the Holocene
The distribution of the guanaco ( Lama guanicoe ) in Patagonia during Late Pleistocene–Holocene and its importance for prehistoric human diet
The great importance of the guanaco ( Lama guanicoe) for the subsistence of the human populations of Patagonia during the Holocene has been demonstrated in numerous studies. This species is considered as the main prey of the hunter-gatherer groups of the Patagonian interior, indicating the existence of a strong ecological relationship of predator-prey type. Despite the importance of this ungulate for prehistoric human populations, its spatial dis…
Human diet evolution in Patagonia was driven by the expansion of Lama guanicoe after megafaunal extinctions
Sources of obsidian artefacts, exchange networks and landscape use in Auca Mahuida (Neuquén, north‐western Patagonia)
The results of the X‐ray fluorescence (XRF) analysis of 59 obsidian samples from 11 archaeological sites in the Auca Mahuida region of north‐western Neuquén, Argentina, are present. They indicate that several obsidian sources were used; however, the intensities of their exploitation were variable. Strong differences appear between the Colorado River basin, characterized by a low variability of obsidian groups from northern Neuquén; the Auca volca…
Cranial and endocranial diversity in extant and fossil atelids (Platyrrhini
OBJECTIVES: Platyrrhines constitute a diverse clade, with the modern Atelidae exhibiting the most variation in cranial and endocast morphology. The processes responsible for this diversification are not well understood. Here, we present a geometric morphometric study describing variation in cranial and endocranial shape of 14 species of Alouatta, Ateles, Brachyteles, and Lagothrix and two extinct taxa, Cartelles and Caipora. METHODS: We examined …
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…
Dietary patterns in human populations from northwest Patagonia during Holocene
Diversidad morfológica mandibular de los monos capuchinos
La diversificación de los platirrinos a escala macroevolutiva ha sido sistemáticamente estudiada en años recientes. Sin embargo, el origen de la diversidad fenotípica y de taxones observada a escalas filogenéticas menores, p. ej., dentro de los géneros, ha sido menos estudiada. En este contexto, la diversidad de los monos capuchinos ha sido discutida recientemente. Los trabajos previos reconocían un único género y principalmente cuatro especies. …
Multidisciplinary studies in Cucurbita maxima (squash) domestication
Domestication and human demographic history in South America
OBJECTIVES: The early groups of hunter-gatherers who peopled South America faced significant ecological changes in their trophic niche for a relatively short period after the initial peopling. In particular, the incorporation of cultigens during the Holocene led to a wider trophic niche and probably to an increased carrying capacity of the environment. Here, we study the relationship between the incorporation of domestic resources during the Holo…
Early evolutionary diversification of mandible morphology in the New World monkeys (Primate, Platyrrhini)
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…

Dietary patterns in human populations from northwest Patagonia during Holocene
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…

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…
Exploring Dietary Patterns in the Southernmost Limit of Prehispanic Agriculture in America by Using Bayesian Stable Isotope Mixing Models
The contribution of maize to the diet of prehispanic populations that inhabited Mendoza Province, the thensouthernmost limit of agriculture in America, has been largely debated. Recently, on the basis of d13C data, it was suggested that cacti may mimic the pattern of human isotopic values attributed to maize consumption in this region. These studies relied on a univariate qualitative approach not suitable for accurately identifying dietary contri…
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…
Effect of bite force and diet composition on craniofacial diversification of S outhern S outh A merican human populations
Ecological factors can be important to shape the patterns of morphological variation among human populations. Particularly, diet plays a fundamental role in craniofacial variation due to both the effect of the nutritional status—mostly dependent on the type and amount of nutrients consumed—on skeletal growth and the localized effects of masticatory forces. We examine these two dimensions of diet and evaluate their influence on morphological diver…
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…
Analysis of sexual dimorphism of craniofacial traits using geometric morphometric techniques
This work deals with the assessment of cranial sexual dimorphism in human skeletal samples applying geometric morphometric techniques. The purpose of this research is to apply such techniques to quantitatively describe in craniofacial traits the degree and pattern of shape and size sexual dimorphism. Likewise, we evaluate the precision and accuracy of semilandmark-based techniques for sex estimation. We employ a sample of 125 adult skulls of know…

Encephalization and diversification of the cranial base in platyrrhine primates
The cranial base, composed of the midline and lateral basicranium, is a structurally important region of the skull associated with several key traits, which has been extensively studied in anthropology and primatology. In particular, most studies have focused on the association between midline cranial base flexion and relative brain size, or encephalization. However, variation in lateral basicranial morphology has been studied less thoroughly. Pl…
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…
Evolutionary Relationships Among Prehistoric Human Populations
The study of evolutionary relationships among human populations is fundamental to inferring processes that determine their structure and history. Among the different data types used to infer such relationships, molecular data, particularly nuclear and mitochondrial DNA, are preferred because of their high heritability and the low probability of changes during development. However, although the reliability of relatedness patterns based on other tr…

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…

Was there a population replacement during the Late mid-Holocene in the southeastern Pampas of Argentina? Archaeological evidence and Paleoecological basis
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…
Variation and causal factors of craniofacial robusticity in Patagonian hunter-gatherers from the late Holocene
Fueguian-Patagonian skulls have been characterized as some of the most robust of any modern crania. However, the causal factors of such robusticity remain unsettled. We assess within- and among-sample cranial robusticity of seven samples from continental Patagonia and Tierra del Fuego, using geometric morphometric techniques. In addition, the biomechanical, phylogenetic, and climatic hypotheses proposed to account for robusticity in such samples …
