An Application of Compatibility Analysis to the Blackiths' Data on Orthopteroid Insects

Abstract

A natural concept of agreement among characters is defined in a phylogenetic context. A method for estimating phylogenetic relationships using this concept is described. This method is used to choose, among the characters given by Blackith and Blackith, those that agree. These characters are then used to construct an estimate of phylogenetic relationships among the orthopteroid taxa discussed by these authors. This estimate is compared with the conventional one, and with one determined by the method of Camin and Sokal.
