Reply to Caetano-Anollés et al. comment on “Empirical genome evolution models root the tree of life”
(2018) In Biochimie 149. p.137-138- Abstract
We recently analyzed the robustness of competing evolution models developed to identify the root of the Tree of Life: 1) An empirical Sankoff parsimony (ESP) model (Harish and Kurland, 2017), which is a nonstationary and directional evolution model; and 2) An a priori ancestor (APA) model (Kim and Caetano-Anollés, 2011) that is a stationary and reversible evolution model. Both Bayesian model selection tests as well as maximum parsimony analyses demonstrate that the ESP model is, overwhelmingly, the better model. Moreover, we showed that the APA model is not only sensitive to artifacts, but also that the underlying assumptions are neither empirically grounded nor biologically realistic.
