The Pennell group published a new paper “Evaluating the Performance of Widely Used Phylogenetic Models for Gene Expression Evolution” in Genome Biology and Evolution. The study analyses previously published multi-species gene expression datasets to evaluate both the relative fit of alternative trait models as well as the absolute fit of the best of the set.

Dr. Matt Pennell also published a News and Views article in Nature. In this perspective, he discusses emerging statistical discoveries that may confound estimates for when major groups of organisms originated. Read the paper here.
