Modeling lineage and phenotypic diversification in the New World monkey (Platyrrhini, Primates) radiation [PDF]

open access: yes, 2013
Adaptive radiations that have taken place in the distant past can now be more thoroughly studied with the availability of large molecular phylogenies and comparative data drawn from extant and fossil species.

Centromeric enrichment of LINE-1 retrotraposon in two species of South American monkeys Alouatta belzebul and Ateles nancymae (Platyrrhini, Primates)

open access: yesCaryologia, 2022
LINE-1 are retrotransposable elements, a kind of repetitive DNA included in the heterochromatin regions of chromosomes. Repetitive DNA represent one of the major genomic components which role is not still clear challenging genomic assembly.

Divergence Times and the Evolutionary Radiation of New World Monkeys (Platyrrhini, Primates): An Analysis of Fossil and Molecular Data [PDF]

open access: yes, 2013
The estimation of phylogenetic relationships and divergence times among a group of organisms is a fundamental first step toward understanding its biological diversification.

Phylogeny and adaptive evolution of the brain-development gene microcephalin (MCPH1) in cetaceans. [PDF]

open access: yes, 2011
BACKGROUND: Representatives of Cetacea have the greatest absolute brain size among animals, and the largest relative brain size aside from humans. Despite this, genes implicated in the evolution of large brain size in primates have yet to be surveyed in ...

A Molecular Phylogeny of Living Primates [PDF]

open access: yes, 2011
Comparative genomic analyses of primates offer considerable potential to define and understand the processes that mold, shape, and transform the human genome.

Contribution à l’étude de la mobilité de l’hallux et de la phylogénie des primates actuels

open access: yesRevue de Primatologie, 2015
Material and methods: 51 anatomical specimens of non-human primates were dissected (18 embalmed, 33 fresh). The amplitudes of the medial cuneometatarsal and metatarsophalangeal articulations of the first ray of the foot of the various fresh pieces and ...

Identification and diversity of killer cell Ig-like receptors in Aotus vociferans, a New World monkey. [PDF]

open access: yesPLoS ONE, 2013
Previous BAC clone analysis of the Platyrrhini owl monkey KIRs have shown an unusual genetic structure in some loci. Therefore, cDNAs encoding KIR molecules from eleven Aotus vociferans monkeys were characterized here; ten putative KIR loci were found ...

Origin and Deep Evolution of Human Endogenous Retroviruses in Pan-Primates

open access: yesViruses, 2022
Human endogenous retroviruses (HERVs) are viral “fossils” in the human genome that originated from the ancient integration of exogenous retroviruses. Although HERVs have sporadically been reported in nonhuman primate genomes, their deep origination in ...

But how does it smell? An investigation of olfactory bulb size among living and fossil primates and other euarchontoglirans

open access: yesThe Anatomical Record, EarlyView.
Analysis of cranial endocast data of 181 extant and 41 fossil species from Euarchontoglires shows that there was a reduction in olfactory bulb size in Crown Primates, but that there were also subsequent reductions in various other primate clades (Anthropoidea, Catarrhini, Platyrrhini, crown Cercopithecoidea, Hominoidea).

Characterising a microsatellite for DRB typing in Aotus vociferans and Aotus nancymaae (Platyrrhini). [PDF]

open access: yesPLoS ONE, 2014
Non-human primates belonging to the Aotus genus have been shown to be excellent experimental models for evaluating drugs and vaccine candidates against malaria and other human diseases.
