The timing of eukaryotic evolution: does a relaxed molecular clock reconcile proteins and fossils?
The use of nucleotide and amino acid sequences allows improved understanding of the timing of evolutionary events of life on earth. Molecular estimates of divergence times are, however, controversialExpand

The tribal radiation of the family Bovidae (Artiodactyla) and the evolution of the mitochondrial cytochrome b gene.
The nucleotide sequence of the complete mitochondrial cytochrome b gene has been determined and compared for 51 species of the family Bovidae and 10 potential pecoran and tragulid outgroups. AExpand

Influence of Tertiary paleoenvironmental changes on the diversification of South American mammals: a relaxed molecular clock study within xenarthrans
BackgroundComparative genomic data among organisms allow the reconstruction of their phylogenies and evolutionary time scales. Molecular timings have been recently used to suggest that environmentalExpand

From the Old World to the New World: a molecular chronicle of the phylogeny and biogeography of hystricognath rodents.
Hystricognath rodents include Old World Phiomorpha and New World Caviomorpha. These two groups have an enigmatic biogeographical history. Using a nuclear marker, the exon 28 of the von WillebrandExpand

The mitochondrial control region of Cervidae: evolutionary patterns and phylogenetic content.
The mitochondrial control region (CR) sequence, also known as the D-loop, has been determined for six Cervidae (Artiodactyla, Ruminantia): the red and fallow deers (subfamily Cervinae), the brocketExpand

An updated 18S rRNA phylogeny of tunicates based on mixture and secondary structure models
BackgroundTunicates have been recently revealed to be the closest living relatives of vertebrates. Yet, with more than 2500 described species, details of their evolutionary history are still obscure.Expand

Evidence for genetic exchange and hybridization in Trypanosoma cruzi based on nucleotide sequences and molecular karyotype.
Trypanosoma cruzi is thought to undergo predominant clonal evolution, as determined by population genetics studies. However, this model does not exclude occasional recombination, which existence isExpand

Variance of molecular datings, evolution of rodents and the phylogenetic affinities between Ctenodactylidae and Hystricognathi
The von Willebrand factor (vWF) gene has been used to understand the origin and timing of Rodentia evolution in the context of placental phylogeny. vWF exon 28 sequences of 15 rodent families andExpand

Molecular phylogenetics of Diseae (Orchidaceae): a contribution from nuclear ribosomal ITS sequences.
We present here the first molecular phylogeny of tribe Diseae (Orchidoideae: Orchidaceae). Nuclear ribosomal ITS1, 5.8S rDNA, and ITS2 sequences were compared for 30 Diseae, 20 Orchideae, and fourExpand

The evolutionary radiation of Arvicolinae rodents (voles and lemmings): relative contribution of nuclear and mitochondrial DNA phylogenies
BackgroundMitochondrial and nuclear genes have generally been employed for different purposes in molecular systematics, the former to resolve relationships within recently evolved groups and theExpand
