En Argentina, el exceso de peso aumentó continuamente desde el 2005 hasta el presente. Los factores con probada relación con el exceso de peso son socio-ambientales y genéticos. Entre estos últimos, el gen FTO es el más estudiado. El objetivo de este trabajo fue analizar la relación entre dos marcadores del gen FTO (rs9939609 y rs11075997) y variab...

The increased availability of genome‐wide data allows capturing the fine genetic structure of present days populations. Here we analyze the genetic ancestry at a fine scale of an Argentinean Patagonia population to understand the origins beyond the three‐hybrid model, and to compare these results with volunteers' self‐perceived ancestry...
Evaluamos diferentes subregiones del cráneo para detectar si los cambios en la consistencia de los alimentos producen un efecto en la variación de tamaño y forma. Se analizaron tres transiciones económicas poblacionales y tres poblaciones no transicionales. Se digitalizaron noventa coordenadas de landmarks en 3D en una muestra de 459 cráneos y se a...
Self-perception of ethnicity is a complex social trait shaped by both, biological and non-biological factors. We developed a comprehensive analysis of ethnic self-perception (ESP) on a large sample of Latin American mestizos from five countries, differing in age, socio-economic and education context, external phenotypic attributes and genetic backg...
Populations of the South American sea lion (SASL, Otaria byronia) have been intensely exploited for leather and oil in different parts of its distribution range throughout the 19th and 20th centuries, generating large changes in abundance. In Patagonia, the SASL population was reduced by more than 90% of its original abundance, and it began to reco...
Current point cloud extraction methods based on photogrammetry generate large amounts of spurious detections that hamper useful 3D mesh reconstructions or, even worse, the possibility of adequate measurements. Moreover, noise removal methods for point clouds are complex, slow and incapable to cope with semantic noise. In this work, we present body2...
La investigación biomédica está contemplando cada vez más la ancestría genética de las poblaciones, con vistas a potenciales aplicaciones en la prevención sanitaria y en el tratamiento de dolencias población- específicas. Los objetivos fueron indagar sobre la formación en genética, universitaria y posuniversitaria, de médicos/as del país, y relacio...
Objectives:
The diagnosis and treatment of obesity are usually based on traditional anthropometric variables including weight, height, and several body perimeters. Here we present a three-dimensional (3D) image-based computational approach aimed to capture the distribution of abdominal adipose tissue as an aspect of shape rather than a relationshi...
Evteev and Heuzé (1) state that there is no evidence supporting that Chinese, Japanese and Korean populations exhibit cold-adaptation features. However, several facial traits present on these groups were previously interpreted as cold-climate adaptations (2-9). For instance, a composite sample including Chinese, Japanese and Korean individuals show...
Facial asymmetries are usually measured and interpreted as proxies to developmental noise. However, analyses focused on its developmental and genetic architecture are scarce. To advance on this topic, studies based on a comprehensive and simultaneous analysis of modularity, morphological integration and facial asymmetries including both phenotypic...
Significance
Due to its role in humidifying and warming the air before it reaches the lungs, adaptations in the internal nasal anatomy are suspected to have been essential for modern humans and Neanderthals during the settlement of Eurasian harsh landscapes. Unfortunately, the lack of soft-tissue evidence in the fossil record precludes any study of...

Los editores de este libro quieren agradecer a los autores de los capítulos
por su espíritu constructivo a la hora de enfocar, desarrollar y revisar sus
respectivas contribuciones. Se agradece también a Damiana C. Pucciarelli,
quien llevó adelante la traducción al inglés del material Anexo y al Dr. S.
Ivan Perez quien compiló y revisó la base de da...
Accurate gathering of phenotypic information is a key aspect in several subject matters, including biometrics, biomedical analysis, forensics, and many other. Automatic identification of anatomical structures of biometric interest, such as fingerprints, iris patterns, or facial traits, are extensively used in applications like access control and an...
The 'omics' era and its concomitant technological advances have brought great insight into genetics. One of the most promising fields within human genetics is the prediction of physical traits from analysis of genetic material. Besides the predictive potential of DNA, the traceability of pathogenic agents in the human body through molecular analysi...
During its expansion across the globe, Homo sapiens successfully survived to major adaptive challenges as a species, inviting scientific research to plunge into the particularities of continental settlement dynamics. A recurrent paleoanthropological concern is about the understanding of the great deal of craniofacial diversity that evolved into the...
Here we evaluate morphological integration patterns and magnitudes in different skull regions to detect if shifts in morphological integration are correlated to the appearance of more processed (softer) diets.
To do so, three transitional populations were analyzed, including samples from groups that inhabited the same geographical region and for wh...
The bite force is a biomechanical parameter that
indicates the amount of force applied during the mastication
of a type of food. In this paper, we compared the bite force
of six modern human populations which differ in the diets
characteristics. Morphological points were digitized on skull
base photographs, determining the shape of the masticatory...
Antisocial and criminal behaviors are multifactorial traits whose interpretation relies on multiple disciplines. Since these interpretations may have social, moral and legal implications, a constant review of the evidence is necessary before any scientific claim is considered as truth. A recent study proposed that men with wider faces relative to f...
Box and whisker plots of fWHR depicting inter-sexual differences across the populations of each database. a) Howells database; b) Pucciarelli database, c) 2D Geometric Morphometric database, d) 3D Geometric Morphometric database, e) Patagonian groups database. Square: median; box: 25%–75%; whisker: minimum-maximum values. Orange: females, blue: mal...

The adult phenotype is the result of a complex
network of interactions between the genotype and the environment.
Among the factors that contribute to establish the
adult phenotype, developmental processes are particularly
important in determining patterns of variation at different
organization levels within the individual. In this work, two
product...
Different scenarios attempting to describe the initial phases of the human dispersal from Asia into the New World have been proposed during the last two decades. However, some aspects concerning the population affinities among early and modern Asians and Native Americans remain controversial. Specifically, contradictory views based mainly on partia...
El fenotipo craneofacial presente en las poblaciones humanas del noreste asiático es considerado
como una especialización de la morfología craneofacial generalizada del Pleistoceno tardío, y aparece
en el registro arqueológico por primera vez en el este Asiático a mediados del Holoceno. Una
vez evolucionados en Asia, estos rasgos (e.g. marcado apla...
Masticatory loading is one of the main environmental stimuli that generate craniofacial variation among recent humans. Experimental studies on a wide variety of mammals, including those with retrognathic postcanine teeth, predict that responses to masticatory loading will be greater in the occlusal plane, the inferior rostrum, and regions associate...
Neurocranial globularity is one of the few derived traits defining anatomically modern humans. Variations in this trait derive
from multiple and complex interactions between portions of the brain and the size and shape of the cranial base, among other
factors. Given their evolutionary and functional importance, neurocranial globularity is expected...
The structure of the prehistoric population of Northwest Argentina is studied through the
analysis of the phenotypic variability at a regional scale. The sample includes 961 artificially
deformed and not deformed individuals, of both sexes, of post-reproductive ages belonging to four
subregions (Puna, Quebrada of Humahuaca, Valliserrana and Selvas...
