Ray-finned fish phylogeny: Going nuclear!

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.
