From the arid core to the Atlantic coast of North Patagonia: Long-distance human mobility during the Late Holocene revealed by δ18O isoscape spatial modeling
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 …

Inferring past demographic changes at different spatial scales in Northwest Patagonia and central‐south Chile: Comparing absolute dates with molecular data
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: Complementing isotopic analysis with zooarchaeological information
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…

Current and prehistoric human mobility in North Neuquén: An Approach Using Complex Networks and Stable Isotopic Mixing Models
Ontogenetic changes in functional matrices and facial bone remodeling
According to the functional matrix hypothesis, changes in size and shape and localization of facial bones during individual ontogeny are influenced by periosteal and capsular matrices. However, the interaction of the functional matrices with the distribution of areas of bone remodeling has not been extensively studied yet. Here we evaluate the changes in the volume of the paranasal sinuses and orbital capsule with age and their association with f…

Variation in facial bone growth remodeling in prehistoric populations from southern South America
OBJECTIVES: To assess the intraspecific variation in bone remodeling patterns in modern humans, we studied two populations from southern South America that represent the extremes of morphological variation in this region. We particularly analyzed the ontogenetic changes in the patterns of bone growth remodeling and compared the patterns between samples. MATERIALS AND METHODS: We obtained high-resolution casts of the periosteal surface of the uppe…
Hunter-Gatherer Persistence and Demography in Patagonia (Southern South America): The Impact of Ecological Changes during the Pleistocene and Holocene
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: An approach using Binford's frames of reference and Bayesian isotope mixing models

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…

Morphological differentiation of aboriginal human populations from Tierra del Fuego (Patagonia): Implications for South American peopling
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…

Ontogeny of robusticity of craniofacial traits in modern humans: A study of South American populations
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…
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…
Evolutionary Relationships Among Prehistoric Human Populations: An Evaluation of Relatedeness Patterns Based on Facial Morphometric Data Using Molecular Data
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…

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 …
