Consider the data displayed in the taxon x character below for a hypothetical group of plant and work the following problems. Assume that taxa 1-3 comprise a monophyletic group In the space below, construct cladograms representing the possible relationship among these four taxa (WITHOUT looking at the characters--this is just all possible trees for 3 taxa + outgroup). Which of these is the most parsimonious cladogram consistent with the data in the table? Which of the eight characte4rs support this conclusion (e.g., they are synapomorphies for the monophyletic in this tree)? List them by letter. Which of the eight characters support this conclusion (e.g., they are synapomorphies for the monophyletic groups in this tree)? List them by letter. Which of the eight character states represent autapomorphies? List them, and indicate the corresponding character (letter) and taxon. Which of the eight characters represent homoplasy? List them by letter. Consider the data displayed in die taxon x character matrix below for a hypothetical group of plants (once again, assume that the taxa 1-3 comprise a monophyletic group). Propose a phylogeny for these taxa, minimizing the number of evolutionary changes (the most parsimonious tree.)
