Cambio secular de la estatura de poblaciones de la Cuenca de México en la época prehispánica
Diversos trabajos sugieren una tendencia hacia la disminución en la estatura adulta conforme aumenta la dependencia de la agricultura en las distintas poblaciones humanas. En este trabajo analizamos los patrones de variación de la estatura humana adulta en poblaciones que habitaron la Cuenca de México desde épocas tempranas. Hemos implementado el análisis de normalidad de la varianza (ANOVA) y el modelo Relethford-Blangero y nuestros resultados, …
Sex estimation using humeral and femoral head diameters in contemporary and prehispanic mexican populations
In bioarchaeology and forensic anthropology the most reliable skeletal element for sex estimation is the pelvis; nevertheless, when it is missing, other postcranial elements must be used. The main goal of this research is to provide sectioning points for sex assessment from humeral and femoral head diameters for three prehispanic and two contemporary Mexican populations. Using a sliding caliper, a total of 386 (45.3% female and 54.6% male) humera…
Recalibration of the Klales et al. (2012) method of sexing the human innominate for Mexican populations
OBJECTIVES: The aim of this study was to test the accuracy of the Klales et al. (2012) equation for sex estimation in contemporary Mexican population. MATERIALS AND METHODS: Our investigation was carried out on a sample of 203 left innominates of identified adult skeletons from the UNAM-Collection and the Santa María Xigui Cemetery, in Central Mexico. The Klales' original equation produces a sex bias in sex estimation against males (86-92% accura…
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…
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…
Technical Note
The greater sciatic notch (GSN) is one of the most important and frequently used characteristics for determining the sex of skeletons, but objective assessment of this characteristic is not without its difficulties. We tested the robustness of GSN sex classification on the basis of geometric morphometrics (GM) and support vector machines (SVM), using two different population samples. Using photographs, the shape of the GSN in 229 samples from two…
Fibroblast growth factor receptor 1 ( FGFR1 ) variants and craniofacial variation in Amerindians and related populations
FGFR1 polymorphisms, especially rs4647905, can have an important role in the normal human skull variation, primarily due to their influence in head length, which would affect other cephalometric absolute/linear measures as well as indices like CI as a result of the pervasive nature of the morphological integration that characterizes the human skull
