Привожу подпись к этому древу: An example of creating a phylogenetic tree in PAUP* using random text (Pumpkin Pie recipe). A recipe was copied and pasted directly into a nexus file subset of random sequences from Taylor and Knouft (2006). This nexus file was then opened in MacClade to truncate the sequences to the same length to accommodate the recipe. The nexus file was re-opened in PAUP* and executed. The ‘‘NJ’’ command was used to create a neighbor-joining tree and the ‘‘bootstrap’’ command was used for nodal support. All error messages were ignored. The point of the exercise was to show that anyone can insert any text into a nexus file and output a phylogenetic tree, even one with 100% ‘‘support’’ for a bogus clade. PAUP* issues warnings for spacing and symbol errors, not sequence text or homology. A thorough understanding of phylogenetic methods and theory is not required to push buttons in PAUP* to create a tree. This is a great exercise for students to perform when learning the ins and outs of PAUP* and any tree-building software.
