The most recent issue of Systematic Biology has a great new phylogenetic analysis of actinopterygian fishes that uses 10 nuclear genes. Chenhong Li, Guoqing Lu, and Guillermo Orti present an excellent study of ray-finned (actinopterygian) fish phylogeny. The trees generated in this study reflect some very interesting hypotheses of actinopt relationships hypothesized by pre-cladistic evolutionary biologists and ichthyologists. Li et al. present a cutting edge analysis of a very impressive dataset, and offer a new strategy to consider when partitioning data for maximum likelihood or Bayesian phylogenetic analyses.
Dechronization is authored by evolutionary biologists interested in the development and application of methods for estimating phylogeny and making phylogeny-based inferences. The goal of the blog is to provide a forum for discussion of the latest research and methods, while also providing anecdotes, tidbits of natural history, and other related information.
