Distribution of Polymorphisms Associated With Obesity in a Sample of Admixed Mexican Adults
Influencia de variables genéticas y socio-ambientales en el exceso de peso en una muestra de la población de Puerto Madryn, Argentina
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 variables socio-ambientales con el estado nutricional en una muestra de 155 personas de Puerto Madryn, Chu…

Disentangling Signatures of Selection Before and After European Colonization in Latin Americans
Throughout human evolutionary history, large-scale migrations have led to intermixing (i.e., admixture) between previously separated human groups. Although classical and recent work have shown that studying admixture can yield novel historical insights, the extent to which this process contributed to adaptation remains underexplored. Here, we introduce a novel statistical model, specific to admixed populations, that identifies loci under selectio…
Admixture and population dynamics in the Philippines through craniometric analysis
The Philippine population prior to European contact is the result of the arrival to the archipelago of different subgroups and the admixture between them. Taking the skull as a complex genotype resulting from both genetic inheritance and the environment, and assuming populations with phenotypic similarity will have a greater phylogenetic relationship, the possibility of studying admixture based on geometric morphometry and cranial measurements is…

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 analizaron mediante morfometría geométrica. Adicionalmente se estimo la fuerza de mordida para cada g…
Religion and fertility patterns
Catholicism and Protestantism have different ways of promoting the family unit that could influence survival and fertility at a population level. Parish records in the Austrian village of Hallstatt allowed the reconstruction of Catholic and Protestant genealogies over a period of 175 years (1733–1908) to evaluate how religion and social changes affected reproduction and survival. Life history traits such as lifespan beyond 15 years, number of off…
Functional efficiency and life history of Late Holocene lithic points from southern Patagonia
Body shape
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 relationship among classical anthropometric measures. METHODS: A morphometric approach based on landmarks and se…

Automatic feature extraction and classification of Iberian ceramics based on deep convolutional networks
Obesity, genomic ancestry, and socioeconomic variables in Latin American mestizos
The proportion of obesity was heavily dependent on the index and the population. Genomic ancestry has a significant influence on the anthropometric measurements, especially on central adiposity. As a whole, we detected a large interpopulation variation that suggests that better approaches to overweight and obesity phenotypes are needed in order to obtain more precise reference values
Describing the children's body shape by means of Geometric Morphometric techniques
INTRODUCTION: Large shape variations take place during the growth process of children, including quantitative mass and size increase plus qualitative changes in their body shape. The aim of the present study is to apply Geometric Morphometric techniques in order to visualize and quantify such body shape differences in healthy children aged 6-59 months with optimal nutritional status. MATERIALS AND METHODS: Anthropometrical measurements of weight,…
Variation in dental morphology and inference of continental ancestry in admixed Latin Americans
Objectives To investigate the variation in dental nonmetric traits and to evaluate the utility of this variation for inferring genetic ancestry proportions in a sample of admixed Latin Americans. Materials and Methods We characterized a sample from Colombia ( N = 477) for 34 dental traits and obtained estimates of individual Native American, European, and African ancestry using genome‐wide SNP data. We tested for correlation between dental traits…
Testing an ethnographic analogy through geometric morphometrics
Measuring fitness heritability
Objectives Traditional interpretation of Fisher's Fundamental Theorem of Natural Selection is that life history traits (LHT), which are closely related with fitness, show lower heritabilities, whereas morphological traits (MT) are less related with fitness and they are expected to show higher heritabilities. In humans, although few studies have examined the heritability of LHT and MT, none of them have analyzed the same sample for comparative pur…

En este trabajo se evalúa la relación entre la asimetría fluctuante facial (AFF) y los tratamientos hormonales, cirugías maxilofaciales, ortodoncia, traumatismos y malformaciones. En el marco del proyecto CANDELA, se tomaron cinco fotografías faciales de 3162 voluntarios entre los 18 y 85 años. Por fotogrametría se colocaron 34 landmarks o puntos en 3D y mediante el método Procrustes ANOVA se obtuvieron valores individuales de asimetría fluctuant…
Shifts in subsistence type and its impact on the human skull's morphological integration
OBJECTIVE: 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. METHODS: To do so, three transitional populations were analyzed, including samples from groups that inhabited the same geographical region and for which the evidence shows that major changes occurred in their subsistence mode. Ni…
The relationship between facial shape asymmetry and attractiveness in Mexican students
OBJECTIVES: It has been postulated that symmetric faces are considered more attractive than asymmetric ones because symmetry may signal high quality due to developmental stability. However, other studies showed that both symmetric and slightly asymmetric faces are considered attractive. Here we aim to explore this discrepancy, beginning with the analysis of the normal prevalence of facial symmetry in a population as a necessary first step prior t…
Ancient remains and the first peopling of the A mericas
OBJECTIVE: A noticeably well-preserved ∼12.500 years-old skeleton from the Hoyo Negro cave, Yucatán, México, was recently reported, along with its archaeological, genetic and skeletal characteristics. Based exclusively on an anatomical description of the skull (HN5/48), Chatters and colleagues stated that this specimen can be assigned to a set of ancient remains that differ from modern Native Americans, the so called "Paleoamericans". Here, we ai…
Facial asymmetry and genetic ancestry in L atin A merican admixed populations
Fluctuating and directional asymmetry are aspects of morphological variation widely used to infer environmental and genetic factors affecting facial phenotypes. However, the genetic basis and environmental determinants of both asymmetry types is far from being completely known. The analysis of facial asymmetries in admixed individuals can be of help to characterize the impact of a genome's heterozygosity on the developmental basis of both fluctua…
FGFR1 signaling is associated with the magnitude of morphological integration in human head shape
OBJECTIVES: The head can be used as a model to study complex phenotypes controlled simultaneously by morphological integration (MI) due to common factors, and modular patterns caused by local factors affecting the development and functional demands of specific structures. The fibroblast growth factor and receptor system (FGF/FGFR) participates in cell communication and pattern formation in osseous tissues, among others, and there is compelling ev…
Bite force estimates and its relationship with characteristics of diet
La fuerza de mordida (FM) es un parámetro biomecánico que indica la cantidad de fuerza que se aplica durante la masticación de un determinado tipo de alimento. En este trabajo se compararon las FM de seis poblaciones de humanos modernos que difieren en las características de sus dietas. A partir de fotografías de la base del cráneo se digitalizaron puntos morfológicos que determinan la forma de los músculos masticadores y permiten las estimacione…
Identifying design and reduction effects on lithic projectile point shapes
The peopling of America
Twenty‐two years ago, Greenberg, Turner and Zegura ( Curr. Anthropol. 27,477–495, 1986) suggested a multidisciplinary model for the human settlement of the New World. Since their synthesis, several studies based mainly on partial evidence such as skull morphology and molecular genetics have presented competing, apparently mutually exclusive, settlement hypotheses. These contradictory views are represented by the genetic‐based Single Wave or Out o…
Size and Shape Variation in Late Holocene Projectile Points of Southern Patagonia
Since the beginning of systematic archaeological studies in southern Patagonia (Argentina and Chile), projectile points have played an important role as cultural markers. A sequence of projectile point types was established according to their changes in size and shape. These stone tools, along with others cultural evidences, served to differentiate a series of “culturai periods” which were, for decades, the frame of reference to understand the cu…

Patterns of phenotypic covariation and correlation in modern humans as viewed from morphological integration
Proportionality of phenotypic and genetic distance is of crucial importance to adequately focus on population history and structure, and it depends on the proportionality of genetic and phenotypic covariance. Constancy of phenotypic covariances is unlikely without constancy of genetic covariation if the latter is a substantial component of the former. If phenotypic patterns are found to be relatively stable, the most probable explanation is that …
Craniometric variation and the settlement of the Americas
New archaeological findings and the incorporation of new South American skull samples have raised fundamental questions for the classical theories of the Americas' settlement. The aim of this study was to estimate craniometric variability among several Asian and Native American populations in order to test goodness of fit of the data to different models of ancient population entries and dispersions into the New World. Our data set includes Howell…
The Settlement of Patagonia
Matrix correlation represents an innovative methodology to evaluate the explanatory power of several hypotheses by measuring their correspondence with observed morphological variation. In this paper, we view the origins of Patagonians from a matrix correlation approach. Personal and published data on nonmetric cranial traits were used to estimate a biological distance matrix involving five major groups from Patagonia and two from the northwest an…
Early Holocene human skeletal remains from Cerca Grande, Lagoa Santa, Central Brazil, and the origins of the first Americans
We present the results of comparative multivariate morphological analyses based on nine skulls from Cerca Grande. The site is in the Lagoa Santa karst in Central Brazil, a key area for understanding the peopling of the Americas. The region has several archaeological sites with excellent preservation of late Pleistocene and early Holocene material culture and human skeletal remains. Stratigraphic association and direct dating of the Cerca Grande h…
Functional‐cranial approach to the influence of economic strategy on skull morphology
Environmental factors are assumed to play an important role in the shaping of craniofacial morphology. Here we propose a statistical approach which can be of utility in estimating the magnitude and localization of a particular nongenetic factor upon the specific functional components of the skull. Our analysis is a combination of previous attempts of apportionment of variance and the application of craniofunctional theory. The effect of subsisten…
The influence of masticatory loading on craniofacial morphology
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 associated with the attachments of the temporalis and masseter muscles. Here we test these experimentally‐der…

Late Pleistocene/Holocene craniofacial morphology in Mesoamerican Paleoindians
Several studies on craniofacial morphology showed that most Paleoindians, who were the first settlers of the New World, clearly differ from modern Amerindians and East Asians, their supposed descendants and sister group, respectively. Here we present new evidence supporting this view from the Late Pleistocene/Early Holocene horizon from Mexico, as well as from the most complete set of dated Paleoindian remains. We analyzed the phenotypic resembla…

Phenotypic evolution of human craniofacial morphology after admixture
An evolutionary, diachronic approach to the phenotypic craniofacial pattern arisen in a human population after high levels of admixture and gene flow was achieved by means of geometric morphometrics. Admixture has long been studied after molecular data. Nevertheless, few efforts have been made to explain the morphological outcome in human craniofacial samples. The Spanish‐Amerindian contact can be considered a good scenario for such an analysis. …
South Amerindian craniofacial morphology
The most compelling models concerning the peopling of the Americas consider that modern Amerindians share a common biological pattern, showing affinities with populations of the Asian Northeast. The aim of the present study was to assess the degree of variation of craniofacial morphology of South American Amerindians in a worldwide context. Forty‐three linear variables were analyzed on crania derived from American, Asian, Australo‐Melanesian, Eur…
Evaluating microevolutionary models for the early settlement of the New World
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 partial evidence such as skull morphology or molecular genetics have led to hypotheses such as the "Two Wa…
