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…
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…
A geometric morphometric approach to the study of variation of shovel‐shaped incisors
OBJECTIVES: The scoring and analysis of dental nonmetric traits are predominantly accomplished by using the Arizona State University Dental Anthropology System (ASUDAS), a standard protocol based on strict definitions and three-dimensional dental plaques. However, visual scoring, even when controlled by strict definitions of features, visual reference, and the experience of the observer, includes an unavoidable part of subjectivity. In this metho…
Relación entre tratamiento hormonal, cirugía-ortodoncia maxilofacial, traumatismos y malformaciones craneofaciales y la asimetría fluctuante
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…
Puede El Adn Mitocondrial Proporcionar Información Sobre La Etnogénesis De Los Pueblos Originarios Chilenos
A pesar del esfuerzo realizado por numerosos investigadores, el conocimiento existente acerca del origen de la mayoría de los pue- blos originarios chilenos continúa siendo fragmentario y parcialmente contradictorio. En consecuencia nos hemos propuesto como objetivo contribuir al esclarecimiento de este importante aspecto de la historia del pueblo chileno, ofreciendo un enfoque desde la perspectiva de la genética histórica. Examinamos, en primer …
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…
