Building the Tree of Life, Genome by Genome

sea-maid submitted, created time 4 months 4 weeks (www.sciencemag.org)

Phylogenetic studies have gone 'omic. Whereas researchers used to be satisfied comparing one gene, or a few, to sort out the branching of the tree of life, the push now among those building phylogenies is to consider whole genomes--at the very least, dozens of genes and thousands of DNA bases--in establishing kinships among flora and fauna. In this way, evolutionary biology is joining the bandwagon of data-intensive studies pioneered by genomics

Fossils, Molecules, Divergence Times, and the Origin of Lissamphibians

A review of the paleontological literature shows that the early dates of appearance of Lissamphibia recently inferred from molecular data do not favor an origin of extant amphibians from temnospondyls, contrary to recent claims. A supertree is assembled using new Mesquite modules that allow extinct taxa to be incorporated into a time-calibrated phylogeny with a user-defined geological time scale. The supertree incorporates 223 extinct species of lissamphibians and has a highly significant stratigraphic fit

Phylemon: a suite of web tools for molecular evolution, phylogenetics and phylogenomics

channel submitted, created time 1 year 7 months (nar.oxfordjournals.org)

The Phylemon web server is available at http://phylemon.bioinfo.cipf.es. Phylemon is an online platform for phylogenetic and evolutionary analyses of molecular sequence data. It has been developed as a web server that integrates a suite of different tools selected among the most popular stand-alone programs in phylogenetic and evolutionary analysis. It has been conceived as a natural response to the increasing demand of data analysis of many experimental scientists wishing to add a molecular evolution and phylogenetics insight into their research.
