Data from: Arrival and diversification of caviomorph rodents and platyrrhine primates in South America.

Céline Poux, Pascale Chevret, Dorothée Huchon, Wilfried W. De Jong & Emmanuel J. P. Douzery
Platyrrhine primates and caviomorph rodents are clades of mammals that colonized South America during its period of isolation from the other continents, between 100 and 3 million years ago (Mya). Until now, no molecular study investigated the timing of the South American colonization by these two lineages with the same molecular data set. Using sequences from three nuclear genes (ADRA2B, vWF, and IRBP, both separate and combined) from 60 species, and eight fossil calibration constraints,...

Data from: Tunicate mitogenomics and phylogenetics: peculiarities of the Herdmania momus mitochondrial genome and support for the new chordate phylogeny

Tiratha R. Singh, Georgia Tsagkogeorga, Frédéric Delsuc, Samuel Blanquart, Noa Shenkar, Lossi Loya, Emmanuel J. P. Douzery & Dorothée Huchon
BACKGROUND: Tunicates represent a key metazoan group as the sister-group of vertebrates within chordates. The six complete mitochondrial genomes available so far for tunicates have revealed distinctive features. Extensive gene rearrangements and particularly high evolutionary rates have been evidenced with regard to other chordates. This peculiar evolutionary dynamics has hampered the reconstruction of tunicate phylogenetic relationships within chordates based on mitogenomic data. RESULTS: In order to further understand the atypical evolutionary dynamics of the mitochondrial...

Data from: An updated 18S rRNA phylogeny of tunicates based on mixture and secondary structure models

Georgia Tsagkogeorga, Xavier Turon, Russell R. Hopcroft, Marie-Ka Tilak, Tamar Feldstein, Noa Shenkar, Yossi Loya, Dorothée Huchon, Emmanuel J. P. Douzery & Frédéric Delsuc
BACKGROUND: Tunicates 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. From a molecular point of view, tunicate phylogenetic relationships have been mostly studied based on analyses of 18S rRNA sequences, which indicate several major clades at odds with the traditional class-level arrangements. Nonetheless, substantial uncertainty remains about the phylogenetic relationships and taxonomic status of key groups...
