..., they compare their results with a master Tree of Trees to identify instances of homology and homoplasy. After delivering this activity, the majority of students scored the activity as “helpful to very helpful” in increasing their understanding of these concepts. Overall, we deliver a framework for...

..., determine polarity through outgroup comparison, and construct a parsimonious tree based on synapomorphies (shared derived characters). This activity efficiently demonstrates many systematics concepts, including homology, homoplasy (convergence and reversal), polarity, synapomorphy, symplesiomorphy...

Figure 3. Ancestral state reconstructions of reproductive traits for the 67 SCU campus trees. Reproductive mode (cones versus flowers) is homologous (A) , whereas the evolution of fruit types (dry versus fleshy) is homoplasious because of convergence and reversals (B) . When the trait is not

... potential problem with this approach is that it may artificially group together dragons with the same type of breath weapon in a way that renders other synapomorphies (such as the pointed tongue of metallic dragons) as homoplasies instead. It would be worthwhile to discuss with the students how this leads...
