The current status of the New World monkey phylogeny
Anais da Academia Brasileira de Ciências, 2000 Four DNA datasets were combined in tandem (6700 bp) and Maximum parsimony and Neighbor-Joining analyses were performed. The results suggest three groups emerging almost at the same time: Atelidae, Pitheciidae and Cebidae.

A new karyotype inCallicebus Torquatus(Cebidae, Primates) [PDF]
Hereditas, 2000 We describe a new karyotype of Callicebus torquatus using conventional staining, G-banding with Wright Stain, CBG, Ag-NOR staining and fluorescence in situ hybridization (FISH) with human telomere probes and comparative analysis with the previously reported karyotype of C. torquatus torquatus (2n = 20).

Incisor cross-sectional area at the cementoenamel junction correlates with an increased reliance on frugivory in anthropoid primates. [PDF]
Anat Rec (Hoboken)Abstract Diet is one of a limited set of key ecological parameters defining primate species. A detailed understanding of dental functional correlates with primate diet is a key component for accurate dietary inference in fossil primates. Although considerable effort has been devoted to understanding post‐canine dental function, incisor function remains

Characterization of Satellite DNAs in Squirrel Monkeys genus Saimiri (Cebidae, Platyrrhini) [PDF]
Scientific Reports, 2020 Abstract The genus Saimiri is a decades-long taxonomic and phylogenetic puzzle to which cytogenetics has contributed crucial data. All Saimiri species apparently have a diploid number of 2n = 44 but vary in the number of chromosome ...

Sperm Morphology in Neotropical Primates
Animals, 2019 The morphological and morphometric characterization of spermatozoa has been used as a taxonomic and phylogenetic tool for different species of mammals. We evaluated and compared the sperm morphometry of five neotropical primate species: Alouatta caraya ...

Characterization of Stone Tool Use in Wild Groups of Critically Endangered Yellow-Breasted Capuchin Monkeys (Sapajus xanthosternos). [PDF]
Am J Biol AnthropolFirst camera trap video footage for wild Sapajus xanthosternos cracking resistant nuts with stone tools. ABSTRACT Objectives A hallmark of hominin evolution is the advent and diversification of stone tool use, and biological anthropologists have a particular interest in characterizing tool use behaviors in different hominin species.

Genetics and Molecular Biology, 2000 Mitochondrial DNA-like sequences have been found in the nuclei of a variety of organisms. These nuclear pseudogenes can be used to estimate relative evolutionary rates of mitochondrial genes, and can be used as outgroups in phylogenetic analyses. In this
