Correction to <i> <scp>Addressing Polymorphism in Linguistic Phylogenetics</scp> </i>

Abstract In Canby et al. 2024, TPS 122(2), 199–222, we provided a new model of linguistic evolution that addressed polymorphism, a simulation study comparing several phylogeny estimation methods under this model showing that a maximum parsimony method (MP4) had the best accuracy, and a phylogenetic analysis using maximum parsimony of an updated Ringe &amp; Taylor IE dataset with polymorphic characters included. We recently discovered that the way we estimated phylogenetic trees for the simulation study used an incorrect script for performing binary encodings of multi‐state characters (originally developed for a different question) that did not produce a binary encoding for any monomorphic character. Here, we provide the updated figures and table that have correct values for the methods that employ the binary encoding in the simulation studies we performed.
