An interesting discussion on how to remove size from phylogenetic comparative analyses of morphological data is playing out on the R-sig-phylo list-serv (a forum about the use and development of phylogenetic and comparative methods within the R platform). This topic has been contentious for a some time and the ongoing discussion should be of interest to anyone looking to analyze morphological data in a phylogenetic context. Several heavy hitters (Ted Garland & Joe Felsenstein) and Dechronization bloggers (Dan Rabosky & Liam Revell) have already weighed in with insightful remarks.
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.
