On the interpretation of results returned by branch-site models
Keyword(s):
In a recent study, Murrell et al. (2015) compared the performance of several branch-site models of codon evolution. Their interpretation of results published by Lu & Guindon (2014) suggests that the stochastic branch-site model implemented in the software fitmodel is anti-conservative altogether, i.e., positive selection is detected more often than expected when analyzing sequences evolving under a mixture of neutrality and negative selection. I argue here that this presentation of the performance of fitmodel is misleading and should not deter evolutionary biologists from using this approach in exploratory analyses of selection patterns at the molecular level.
