The availability of whole genome sequences was expected to supply essentially unlimited
data for phylogenetics. However, strict reliance on single-copy genes for this purpose has …

When a phylogenetic reconstruction does not result in one tree but in several, tree metrics
permit finding out how far the reconstructed trees are from one another. They also permit to …

Background The availability of hundreds of bacterial genomes allowed a comparative
genomic study of the Type VI Secretion System (T6SS), recently discovered as being …

Spiny-rayed fishes (Acanthomorpha) dominate modern marine habitats and account for
more than a quarter of all living vertebrate species. Previous time-calibrated phylogenies …

The origins and the divergence times of the most basal lineages within primates have been
difficult to resolve mainly due to the incomplete sampling of early fossil taxa. The main …

We present Procrustean Approach to Cophylogeny (PACo), a novel statistical tool to test for
congruence between phylogenetic trees, or between phylogenetic distance matrices of …

Abstract Background The Nucleo-Cytoplasmic Large DNA Viruses (NCLDV) comprise an
apparently monophyletic class of viruses that infect a broad variety of eukaryotic hosts …

Delimiting and describing species is fundamental to numerous biological disciplines such as
evolution, macroecology, and conservation. Delimiting species as independent evolutionary …

Background Comparative genomics has revealed extensive horizontal gene transfer among
prokaryotes, a development that is often considered to undermine the'tree of life'concept …

Phylogenetic networks are a generalization of phylogenetic trees that allow for the
representation of nontreelike evolutionary events, like recombination, hybridization, or …
