Introduction
============

A fundamental problem in evolutionary biology is to determine relative relatedness of species, usually by seeking a rooted tree that diagrammatically depicts these relationships. Although phylogenetic methods of inferring relationships between genes sampled from individuals in the different species are now highly developed, such gene trees are not species trees. Even in the absence of errors due to estimating gene trees from DNA sequences, gene tree topologies need not match the underlying species tree. In recent years, various methods have been proposed for inferring species trees from genetic data [@degnan2009; @edwards2009; @KK]. Many of these methods first estimate gene trees, and then resolve the possible conflicts among them
