Data from: Patterns of cranial shape diversification during the phylogenetic branching process of New World monkeys (Primates: Platyrrhini)

Sergio I Perez, Júlia Klaczko, Guido Rocatti & Sergio F Dos Reis
One of the central topics in evolutionary biology is understanding the processes responsible for phenotypic diversification related to ecological factors. New World monkeys are an excellent reference system to investigate processes of diversification at macroevolutionary scales. Here, we investigate the cranial shape diversification related to body size and ecology during the phylogenetic branching process of platyrrhines. To investigate this diversification, we used geometric morphometric techniques, a molecular phylogenetic tree, ecological data and phylogenetic comparative methods....

Data from: Early evolutionary differentiation of morphological variation in the mandible of South American caviomorph rodents (Rodentia, Caviomorpha)

Alicia Álvarez, Sergio I Perez & Diego H Verzi
Caviomorphs are a clade of South American rodents recorded at least since the early Oligocene (>31.5 Ma) that exhibit ample eco-morphological variation. It has been proposed that phylogenetic structure is more important than ecological factors for understanding mandibular shape variation in this clade. This was interpreted as a result of the long-standing evolutionary history of caviomorphs and the early divergence of major lineages. In this work we test this hypothesis through analysis of morphological variation...

Data from: Pervasive genetic integration directs the evolution of human skull shape

Neus Martínez-Abadías, Mireia Esparza, Torstein Sjøvold, Rolando González-José, Mauro Santos, Miquel Hernández & Christian Peter Klingenberg
It has long been unclear whether the different derived cranial traits of modern humans evolved independently in response to separate selection pressures or whether they resulted from the inherent morphological integration throughout the skull. In a novel approach to this issue, we combine evolutionary quantitative genetics and geometric morphometrics to analyze genetic and phenotypic integration in human skull shape. We measured human skulls in the ossuary of Hallstatt (Austria), which offer a unique opportunity because...
