A Phylolinguistic Classification of the Quechua Language Family

We present a computational phylogeny for the internal classification of the Quechua language family. Based on a concept list of 150 lexical items, we manually analyzed data from 39 contemporaneous Quechua varieties for cognacy and computed a family tree using Bayesian phylogenetic methods. The results provide further evidence for the classification of individual varieties and compares the results to the existing hypotheses for the evolution of the Quechua language family.
