Differences between sliding semi‐landmark methods in geometric morphometrics, with an application to human craniofacial and dental variation
Comparing the results obtained by bootstrapped‐based Goodall's F‐test, Foote's measurement, principal component (PC) and discriminant function analyses on human molars and craniometric data shows that both criteria yield different estimates of within‐ and between‐sample variation. Expand
Geometric morphometric approach to sex estimation of human pelvis.
The use of geometric morphometrics and multivariate statistics is a reliable method to quantify pelvic shape differences between the sexes and could be applied to discriminate between females and males. Expand
Artificial cranial deformation in South America: a geometric morphometrics approximation
The bioarchaeological record of South America is characterized by the high frequency of individuals with a variety of cranial deformations concentrated in three areas (North-West, Central-West andExpand
Species tree estimation for a deep phylogenetic divergence in the New World monkeys (Primates: Platyrrhini).
This work used coding and non-coding sequences to infer the species tree and embedded gene trees of the platyrrhine genera using the Bayesian Markov chain Monte Carlo method for the multispecies coalescent (*BEAST) for the first time and compared the results with those of a Bayesian concatenated phylogenetic analysis.

Divergence Times and the Evolutionary Radiation of New World Monkeys (Platyrrhini, Primates): An Analysis of Fossil and Molecular Data
The estimates based on the two approaches used in this study recalibrate the ages of the major platyrrhine clades and corroborate the hypothesis that they constitute very old lineages, and show that the use of different approaches and well supported fossil information gives a more robust divergence time estimate of a clade.

Brain shape convergence in the adaptive radiation of New World monkeys
It is shown that brain morphology evolved in association with the occupation of several ecological niches, and that convergence in brain morphology among clades may be associated with an evolutionary increase in the complexity of social behaviors. Expand
Role of wild plant foods among late Holocene hunter-gatherers from Central and North Patagonia (South America): an approach from dental evidence.
The results indicate that caries percentages in Patagonian samples fall within the range established for hunter-gatherers but there are significant geographical differences, and there is a marked temporal trend toward the reduction of wear rates in the three areas, suggesting a change to less hard and/or abrasive diets in the final late Holocene.

Early Holocene human remains from the Argentinean Pampas: additional evidence for distinctive cranial morphology of early South Americans.
The first craniometric study of three early skulls from the Argentinean Pampas are shown to be morphologically similar to other Early Holocene American skulls that exhibit long and narrow cranial vaults, which underscore the important differences in cranial morphology between early and late-American samples.

Ontogeny of robusticity of craniofacial traits in modern humans: a study of South American populations.
The results obtained indicate that the pattern of interpopulation variation in shape and size is already established at the age of 5 years, meaning that processes acting early during ontogeny contribute to the adult variation. Expand
Discrepancy between Cranial and DNA Data of Early Americans: Implications for American Peopling
Comparing craniometric and mtDNA data of diachronic samples from East Central Argentina dated from 8,000 to 400 years BP shows that even when the oldest individuals display traits attributable to Paleoamerican crania, they present the same mtDNA haplogroups as later populations with Amerindian morphology.
