| Abstract: | A simple statistical test for comparing three alternative phylogenetichypotheses for four monophyletic groups is presented. This test is based onthe minimum-evolution principle, and it does not require any informationregarding the branching order within each monophyletic group. It iscomputationally efficient and can be easily extended to five or moremonophyletic groups. |
